1 Introduction
1.1 Dimmable lighting systems
Dimmable electronic control gears (DIM ECGs) are playing an
increasingly important role in all areas of application of modern
lighting technology. Dimmable ECGs from OSRAM, integrated in a
building management system, form the heart of intelligent lighting systems
which save up to 80 % of energy compared to conventional
electronic control gears. The reason for this is that many requirements
of a lighting system are simple and elegant to realize by means of light
control. Economy, lighting comfort, reliability and safety are the driving
forces here.
1.1.1 Economy
Intelligent energy-saving concepts in building management lower the
lighting costs many times over:
• Up to 50 % less power consumption compared to operation with
magnetic, conventional electronic control gears (CCG)
• More than 50 % longer lamp lifetime compared to operation with
ECG and low-loss electronic control gears (LLG) through defined
lamp operation ! Lower maintenance costs
• Lowering of energy costs for air conditioning systems by reducing
the cooling load
Figure 1: Global energy saving potential with dimmable electronic
control gear

1.1.2 Lighting comfort
Lighting situations at the touch of a button (lighting scenes), also with
integrated presence detection and daylight/time-dependent control,
increase lighting comfort. The features of a high-quality dimmable
ECG also include:
• Flicker-free ignition
• Comfortable, continuously dimmable (1(3)…100 %) and flicker-free
lighting without stroboscopic effects
• Virtually noise-free, no irritating humming of chokes (CCG/LLG)
• No flashing of defective lamps
• Automatic restart after lamp replacement
• Easy-to-use, feedback messages to the control unit and configuration
of personal lighting values create individuality
Figure 2: Energy saving and increased lighting comfort through integrated
presence detection with daylight/time-dependent control
This has been made possible mostly thanks to technical developments.
Modern dimmable ECGs with digital (DALI = Digital Addressable
Lighting Interface) or analog (1…10 V) interface in combination
with corresponding control elements, control units and sensors create
the preconditions for simple and low-cost realization of more efficient
and convenient lighting systems.
5

1.1.3 Reliability/Safety
Reliability and safety play a crucial role in the use of electronic control
gear. Key features of high-quality ECGs include:
• Preheating of both lamp filaments
• Dependable lamp ignition to an ambient temperature of -20 °C 1
• Dependable lamp operation in the temperature range of -20 °C to
75 °C
• Dependable shutdown of the ECG in the event of a fault and at
"End of Life" (EoL)
• Compliance with all current applicable ECG standards:
• Safety (EN61347)
• Performance (EN60929)
• Harmonic current emissions (EN61000-3-2)
• Radio interference suppression from 9 kHz to 300 MHz
(EN55015: 2006 + A1:2007)/CDN measurement
• Immunity (EN61547)
1.1.4 The right control unit for every application
Dimmable ECGs have a very wide range of uses. Some examples of
applications are offices and industrial buildings with light-dependent
control, conference and assembly rooms with lighting for the particular
situation or CAD offices and switch rooms with individually adjustable
light levels. The core of the lighting system are the dimmable
QUICKTRONIC Intelligent ® ECGs from OSRAM with DALI or 1…10 V
interface (QTi DALI/DIM) for the operation of compact and fluorescent
lamps. These are controlled by a control unit, a sensor or a simple
button/rotary dimmer switch. The choice of the right dimming components
for controlling the lighting depends on the desired application.
The requirement profile of the dimmable lighting system must, therefore,
be defined in detail.

2.2 DALI in comparison to 1…10 V and EIB/LON
What modern lighting technology needs is a system that is as flexible
as it is simple, a system that focuses on room-based lighting
control with just a few low-cost components, minimal wiring and a
user-friendly operating concept. The lighting industry has therefore developed
a new digital communication standard for lighting systems:
DALI closes the gap between the former 1…10 V technology and
complex bus systems. DALI can be used either as a very simple local
solution or as a subsystem integrated in a building management
system.
Figure 4: Overview of 1…10 V, DALI and EIB/LON
With traditional electrical installations and even with the widely used
analog 1…10 V interface such requirements are very difficult to meet
and involve a great deal of time, effort and expense. A large number
of components have to be used to enable a programmed scene to
be changed, to provide flexible grouping at the same time and then
possibly to integrate these settings in a daylight-dependent control
system.
2.2.1 DALI and 1…10 V characteristics
The basis for any control system are the defined physical properties
at the interface and the properties of the interface cables as the
transmission medium. Thanks to a high signal-to-noise ratio and wide
ranges for digital “low” and “high”, it is virtually impossible with DALI
for data transfer to be affected by interference. Consequently, there is
no need to use shielded control cables. As in the case of the 1...10 V
interface, the mains and control inputs in the ECGs are electrically
isolated. A conscious decision was taken not to use safety extra-low
voltage (SELV) in order to offer low-cost installation without additional
8

special lines or cable penetrations. A 5 x 1.5 mm 2 NYM cable, for
example, can be used for the mains feed and DALI.

2.3 DALI installation & features
2.3.1 Simplified installation
The installation of DALI is carried out with commercially available installation
material for 230 V line voltage. The two wires of the five-wire
cables (e.g. NYM 5 x 1.5 mm²) that are not needed can be used for
the DALI interface - regardless of polarity. Thus, no separate bus cable
is required! The ECG and control unit can be operated on different
line voltage phases.
2.3.2 Construction site mode
The ECGs can be switched on or off at any time via the fuse protection
even if there is no controller installed or programmed (basic DALI
function). With ECGs straight from the factory the lighting is always
switched on at 100 % luminous flux.
2.3.3 Benefits of DALI ECG with group assignment
Each ECG in the DALI system can be addressed individually and digitally.
Each ECG is assigned an address and group association on
start-up. Each ECG may belong to as many as 16 groups – and to
several groups at the same time. The ECGs can be addressed individually,
in groups or all together. The group assignment can be changed
at any time without rewiring.
2.3.4 Integrated scene memory
Each ECG can store up to 16 light values, irrespective of the group
assignments. Fading from one scene to the next is synchronous. This
means that all ECGs start fading to the new scene at the same time
and finish at the same time (by varying the dimming rate).
2.3.5 Status report from the ECG
The control unit can query the status of each and every ECG. This
enables a lamp fault (or failure) or the brightness of a lamp to be determined,
for example. The feedback capability of the OSRAM DALI
ECG is crucial in association with complex bus systems (EIB, LON) in
building management systems (e.g.: the OSRAM BASIC checks for
lamp faults and can forward these via a potential-free message contact;
the OSRAM Advanced provides the option of analysis by means
of the HPT (Hand Programming Tool, see www.osram.com/ecg-lms).
10

2.3.6 No more switching relays
The ECGs are switched on and off via the interface. The former external
relays required for switching are therefore no longer needed.
2.3.7 Addressing is not essential
DALI can also be used without any addressing (groups or individual
addresses). A method known as broadcast mode is used here, which
simply means that all control units are addressed together.
2.4 Installation and wiring instructions
2.4.1 Burning-in instructions/Cable insulation
• For forming and basic stabilization new lamps must be burned in
for 100 hours at 100 % dimmer setting (undimmed). Interruptions
during the burning-in are permissible. In dimming operation without
burning-in this can result in the lamps flickering, premature endblackening
and shorter operating life. For measurements based on
IEC 60081, the lamps must also be correspondingly burned in, in
order to achieve maximum luminous flux and optimum lamp stability.
3
• Dimming is generally only possible with filament preheating. The
filament temperature must be kept constant by auxiliary heating as
this can to lead to effects such as tungsten depletion (sputtering)
or to elevated vaporization of the emitter material.
• The control input (DALI or 1…10 V) is insulated from the mains
(230 V voltage-proof) by basic insulation (not SELV). The mains
cable and control line can therefore be routed together in a 5-core
NYM cable. 4
3
The electrodes of a low pressure discharge lamp are coated with an emitter (barium, strontium and
calcium oxide) to reduce the work function of the electrons from the tungsten filament wire. These
oxides are strongly hygroscopic and interact with the humidity of the air (consequence: relatively low
light yield, high lamp voltage and short service life of the lamp)
! Solution: Intermediate reaction due to carbonate compounds from which the oxides are formed
at temperatures above 600 °C. The actual reduction of the filament work function requires atomic
barium on the emitter surface, which is only fully formed at the max. dimming setting (100 % luminous
flux) and high temperatures (1900 K electrode temperature) over a time period of 100 h. If
these conditions are not fulfilled, an increased cathode voltage drop results and leads to material
deposits on the filament: Reduced service life
4
In accordance with DIN VDE 0100 Part 520 Section 528.11, main current circuits and associated
auxiliary circuits can be laid together, even if the auxiliary circuits carry a lower voltage than the main
current circuits.
11

Note (acc. to DIN VDE 0100/11.85, T 520, Sect. 528.11):
• Cables or lines that are insulated for the maximum operating
voltage must be used, or each conductor of a multi-wire cable/
line must be insulated for the next voltage appearing in the
cable/line.
• When laying conductor lines in electrical installation pipes or
ducts only the conductors of a main power circuit including the
associated auxiliary power circuit may be laid together
• Several main power circuits including the associated auxiliary
power circuits can also be combined in a single cable or line
• Cables and terminals approved for use the mains voltage (230 V)
must be used for the installation
• The installation must be carried out in such a way that when the
supply voltage is switched off, all signal and control cables are also
switched off at the same time
• All components of the main power and control power circuits must
be designed for 250 V working voltage to ground
• All the luminaires must be wired with H05 cables provided U OUT
does not exceed 430 V eff,
and also be subjected to an insulation
test (in accordance with VDE) in conjunction with OSRAM DALI/
DIM ECGs. OSRAM QUICKTRONIC DALI/DIM ECGs do not exceed
430 V eff
even for T5-Ø 16 mm HE and HO florescent lamps.

2.4.2 Safety instructions
Electronic control gear should be installed and maintained by qualified
electricians only
Disconnect electronic control gear from the power supply before
maintenance work
Use indoors only
13

2.4.3 Radio interference suppression of dimmable luminaires
The use of dimmable ECG is only approved in luminaires of protection
class I (PC I) as only here is adequate grounding assured.
Note:
When dimming, the operating frequency of the lamp and the lamp
burning voltage increases at the same time which can lead to elevated
leakage currents. Leakage currents emerging from the lamp always
flow back into the ECG because the current circuit must be closed. To
keep cable-related interference as low as possible, the leakage current
is offered a different return path, the ground conductor (=casing)
and the PE connection of the ECG.
In brief: Dimming is not possible without grounding. Dimmable ECGs
only function in PC I luminaires and not in PC II luminaires as these
have no protection contact. Connecting the dimmable ECG to the
functional ground is not permissible.

The maximum 50 Hz leakage current of the ECG via the ground fault
circuit interrupter (FI switch) is 0.5 mA.
• Mains cables and control lines may be routed together and should
be laid close to the luminaire wall
• Mains and control cables must not be laid close to the lamp cables
• If crossovers of mains and lamp cables are unavoidable, they
should cross perpendicularly
• Do not lay the PE conductor together with the lamp cables
• Do not use shielded lamp cables (reduction of capacity leakage
currents)
• The OSRAM DALI/DIM ECG must always be installed near the
lamp(s) so that the lamp cables can be kept short in the interests of
good radio interference protection
14

Notes:
• Max. lamp cable length of the "hot end" (higher potential to
ground): T5, T8: 1 m/T4: 0.5 m
• Excessively long lamp cables cause the following problems:
- Poor radio interference suppression
- Uncertain lamp detection (not in T8)
- Poor synchronization of 2-lamp OSRAM DALI/DIM ECGs
• Lay the lamp cables close together and close to the lamp
• Lamp cables must not be laid in metal pipes and must not be
shielded cables
• Guide the cables of the different lamp ends separately
• In the case of multi-lamp OSRAM DALI/DIM ECGs, the cables to
the respective lamp ends must be of the same length to prevent
differences in the brightness
• When dimming florescent lamps the maximum lamp voltage is
reached at the lowest dimmer setting (3 %-10 %) due to the negative
current-voltage characteristic

2.4.4 Operation of multiple ECGs in a luminaire
If several dimmable ECGs are operated in a luminaire, there can be
interference effects and hence to flickering, jerky dimming or even to
shutdown of the ECGs if they have not been correctly installed. The
cause for this are inductions between the lamp current circuits of several
ECGs: If a lamp running at 100 % transfers just 1 % of its current
into the neighboring lamp dimmed to 1 %, this represents a fault of
100 %. The same applies to coupling between a heating current circuit,
i.e. feed and return lines to one side of the lamp and the neighboring
lamp circuit.
There should, therefore, be a minimum spacing of 12 cm between the
lamp circuits (lamp and cables) of different ECGs. If this is not possible,
the lamp wiring must be carefully installed so coupling between
the lamp circuits is reduced to a minimum:
• Lay the lamp cables close to the appropriate lamps so that the
area covered by the lamp circuit is as small as possible. The lamp
circuits of the two ECGs must not overlap. This is particularly important
for color control if adjacent ECGs are dimmed to different
levels.
• There should be a spacing of several centimeters between the
lamp cables of two ECGs
• The "short" (hot) lamp cables (see also ECG imprint) should lead to
one side of the lamp and should be as short as possible. The "long“
(cold) lamp cables to the other side of the lamp (see Table 2)
• Mains and control cables should not be laid close to the lamp cables
(prevents undesired couplings into the control cable)
• All the mains and control cables may be routed together. To ensure
that radio interference suppression is not impaired, there should be
a gap of several centimeters to the lamp cables.
16

The better these recommendations are implemented, the more stable
is the light at the lowest dimmer setting, even with a very small lamp
spacing – and, hence, the full temperature range of the ECGs can be
used.
• In the "worst case" twist the cables of the heating circuits together,
hence ensuring they lie close together. With 1-lamp ECGs these
are the 21-22 and 26-27 cables, with 2-lamp ECGs; 21-22 and
21-23, 24-25 and 26-27. This is particularly important if adjacent
ECGs are operated at the lowest dimmer setting (1(3)%).
If there still are problems: Remove all lamps except for the most
"problematic" ECG – this will eliminate possible faults from the other
lamps. If the lamp then works correctly over the entire dimming range,
the decoupling measures for the other lamps (cables) are still not adequate.
2.4.5 Wiring examples of dimmable electronic control gear
Figure 6: Three 1-lamp ECGs
Correct:
The lamp lines are laid close to
the respective lamps.
There are no overlapping lamp
current circuits. The “hot" side
is up and the “cold" is down.
Wrong:
The lamp lines of all ECGs are laid
together, also overlapping lamp
current circuits are formed in this
way.
17

Figure 7: Three 2-lamp ECGs
Correct:
The lamp lines are laid close
to the respective lamps. The
overlapping of the three right
lamp current circuits is minimized.
Wrong:
The lamp lines of all ECGs are laid
together, also overlapping lamp
current circuits are formed in this
way.
Note:
T5 florescent lamps must be used so that the lamp stamps are on
the same side. The lamp stamp must be underneath (Cold Spot) in
the upright burning position. If this is not the case, the lamp parameters
will fluctuate which can lead to unstable burning behavior of the
lamp.
2.5 The DALI interface – technical details
DALI defines the digital communication between a control unit with
DALI interface and a DALI controller (ECG). The detailed specifications
of the DALI interface can be found in IEC 62386.
2.5.1 The DALI system principle
Each control unit works as a "master" and controls communication on
the control cable. ECGs, in contrast, may only respond as a "slave" to
a request of the "master".
DALI relies on consistent intelligence distributed throughout the
system, an intelligent control unit communicates with intelligent components.
For example, the control unit only issues the command:
"Scene 1" and the processor in the ECG adopts the desired light
value. This way all ECGs achieve the set value at the same time.
18

2.5.2 DALI topology
The DALI ECGs are wired in parallel to each other and groups are not
taken into consideration. Star configurations are also possible. Ring
wiring is not permitted (indicated by X in the diagram). There is also no
need for terminating resistors on the communication cable.
Figure 8: DALI topology
2.5.3 DALI parameters in the ECG
The following data can be stored in the DALI ECGs when a DALI
system is started up:
• Group assignment of the DALI ECG (max. 16 groups, multiple
assignment is possible)
• Individual address for accessing each ECG directly (max. 64)
• Lighting values for the individual scenes (max. 16)
• ECG parameters that determine the behavior of the ECG:
• Dimming rate
• Behavior if the voltage fails on the interface (System Failure Level)
• Behavior when the mains voltage is restored (Power On Level)
In addition to the above-mentioned options, it is always possible to
address all the devices together, even without programming the devices
beforehand (construction site function).
19

2.5.4 Requirements to be met by the transmission cable
When selecting a cable make sure that the voltage drop on the line
does not exceed 2 V at 250 mA. As with 1…10 V systems, the power
supply and control line can be run in the same cable. This means, for
example, a 5-core NYM cable can be used to connect the DALI ECG
without any problems. The maximum permitted total length of cable
between the controller and the connected ECG is 300 m.
Cross section of the power cable:
A = L x I x 0.018
A = Line cross section in mm², L = Cable length in meters,
I = Max. current of the supply voltage in A,
0.018 = Specific resistance of copper
The following formula is used as a basis for finding the cable cross
section (transmission and power cable):
Line length up to 100 m 100 to 150 m 150 to 300 m
Line cross section 0.5 mm 2 0.75 mm 2 1.5 mm 2
Note:
Because of the different technical properties of the DALI interface in
control units found on the market and the differing local conditions of
the installation, it is recommended to limit the overall line lengths used
in the system to 300 m.

2.6 DALI data transfer
With DALI, data telegrams are produced by short-circuiting and releasing
the line in order to generate the corresponding "low" or "high"
logic states. This may be caused by either the ECG or by the controller.
In the event of a short-circuit the current is limited by the interface
supply to 250 mA. In the idle state (no data transfer) approx. 16 V DC
is
on the ECG. The following figures illustrate data transfer via DALI:

a logical zero and a rising edge a logical one.
2.6.1 Behavior in the event of a fault
If there is no power at the DALI interface (controller faulty or switched
off), the System Failure Level is set. The Power On Level is activated
after a mains voltage failure (230 V). The System Failure Level has the
higher priority.
Both values are set at the factory to 100 % luminous flux, but can
be individually programmed with the Dali Luminaire Tool (DLT) from
OSRAM, for example.
2.7 The DALI dimming curve
IEC 62386 defines the dimming range of a DALI controller from 0.1 to
100 %. The dimming curve is shown in the graphic below. As far as
the eye is concerned, this categorization is a linear response 5 according
to the Weber-Fechner Law.
5
The Weber-Fechner law states that the subjective strength of sensory stimuli is
logarithmically related to the objective intensity of the physical stimulus.
23

The dependency of the relative luminous flux X (n) on the digital 8-bit
value n is described by the following correlation:
n−1
253
3
X ( n)
− X ( n + 1)
X ( n)
= 10 ! = 2,8 % = Const.
X ( n)
This results in the following graphical association:
Figure 13: DALI dimming curve
2.7.1 Brief overview of the most important dimming values
percentage luminous flux 0 0,1 0,5 1,0 3 5 10 20
digital dimming value 0 1 60 85 126 144 170 195

digital dimming value 210 220 229 235 241 246 250 254
Table 3: Values of digital dimming value against percentage luminous
flux
As not all DALI controllers start at 0.1 % luminous flux, the smallest
value for DALI ECG is 85 for example (corresponds to 1 % luminous
flux). All values below 85 (except for 0 = off) are interpreted as the
minimum light level. To ensure that the transitions from one digital level
to the next are not visible, DALI ECGs from OSRAM feature digital
“smoothing" (this is an additional function of the QTi for increasing
lighting comfort and is not part of the DALI standard).
24

2.8 Features of the digital interface
• IEC 62386 – This allows the combination of units from different
manufacturers. A special feature to be noted is that the DALI manufacturers
represented in the AG DALI. 6 test their units together in
order to guarantee high functional security.
• Physical usable data rate of 1200 bit/s enables fault-free operation
7
• Safe interference voltage gap – the generously dimensioned interference
voltage gap of the high and low level guarantee safe operation
• Data coding – the Manchester code is used; its structure allows
detection of transmission errors
• Maximum system current – the maximum current that a central interface
8 supply must deliver is 250 mA. Each control unit may take
max. 2 mA. This must be taken into consideration when selecting
the interface supply.
• Limited system size – a maximum of 64 control units with an individual
address can be operated differently in a single system
• Feedback of information – ON/OFF, current brightness value of the
connected lamps, lamp status etc. are possible
• Two-wire control line – there should be two basic insulations between
two conductors. Hence, single-layer insulation of a conductor
is adequate. Control and supply lines can be laid together; a
minimum cross section of the line must be maintained here. The
maximum line length between two connected system subscribers
must not exceed 300 meters
• Potential-free control input – the control input is electrically separated
from the mains supply. The ECGs can thus be operated on
different outer conductors (phases)
• No terminating resistors required – the interface lines do not need
to be connected to resistors
6
Every ECG manufacturer that has the DALI logo on its ECG is a member of the
AG DALI

40 commands/s and 16 bits ! 640 bit/s

DALI interface on the control unit:
The DALI interface of the control unit also supplies the DALI interface of the
connected DALI components. To ensure that the total current of max. 250 mA
permitted for DALI is not exceeded, no other DALI supplies or DALI controllers
can be connected to this system. In order not to exceed the max. permissible
voltage drop of 2 V on the interface lines, the line cross section must be chosen
according to the table in the technical details (2.5.4).
25

• Dimming range 1 %…100 % (the lower limit depends on the lamp
and manufacturer). The progression of the characteristic is standardized
and adapted to the sensitivity of the eye (logarithmic
characteristic). Because of the standardization, a similar sense of
brightness is achieved when using control units from different manufacturers
• Programmable dimming times – special settings such as light
change speeds (e.g. from 1 % to 100 % dimmer setting) are possible
• Disconnection of the data line – the specified light values are adopted
automatically
• Storage of light scenes (different group-dependent dimming states)
– up to 16 scenes can be stored
• Connection via converter to building management systems – the
interface is primarily conceived for room applications; it can be integrated
into building management systems via gateways
• Simple system reconfiguration – once the system is set up and
configured, changes of the system function, the light scene and
light functions are only a matter of configuration and do not require
any changes to the hardware. Example: Regrouping of luminaires
in a large office building
• Simple integration of new components – if an existing illumination
system is to be extended, new components can be added anywhere
within the system. Attention must be paid here to adequate
dimensioning of the system supply
• Polarity freedom of the interface
2.9 Characteristics of the 1…10 V interface
Note:
This chapter is based on OSRAM ECGs types QTi DIM and HF DIM,
abbreviated to OSRAM DIM ECGs in the following
• Control is carried out via a fail-safe DC signal of 10 V (maximum
brightness; control line open) to 1 V (minimum brightness; control
line shorted)
• The control power is generated by the ECG (max. current: 0.6 mA
per ECG)
• The voltage on the control line is voltage-insulated from the mains
line (basic insulation), but there is no safety extra-low voltage
(SELV)
• ECGs in different phases can be dimmed by the same controller
26

Note:
Due to the characteristics of the 1…10 V interface, the following must
be noted:
• All control lines of an ECG installation must be connected with the
right polarity (+/-)
• The control line is voltage-insulated from the mains line but there is
no safety extra-low voltage (SELV). Therefore, cables and terminals
that are approved for supply voltage 230V must be used for the
installation
• The control voltage is simple to limit upwards or downwards with
resistors; several control units can be combined with one another
• The correct function of the ECG can be tested as follows:
• Switch-on of the ECG with open control line. The lamp must
ignite and burn with max. luminous flux
• Switch-on of the ECG with shorted control line (wire jumper).
The lamp must burn with min. luminous flux
• Each OSRAM DIM ECG can be used as a normally non-dimmable
ECG if there is no control unit connected to the control line
• The dimmable ECGs are only dimmed via the 1…10 V interface
and switched via the mains line
• The maximum load capacity of the control unit (switched output
and 1…10 V output) must be heeded
• The connected control unit must always be able to handle the current
supplied in the control line by the ECG (current sink) and to
reduce the control voltage. This precept is fulfilled by accordingly
dimensioned potentiometers as well as by all OSRAM control
components. Normal power supplies, converter boards etc. do not
necessarily have this characteristic! To check, connect the control
unit, set to the lowest brightness and measure the voltage on the
control line. The set value is 1V or less
• OSRAM DIM ECGs cannot be dimmed via the mains line (e.g. with
phase control mode, round control pulses etc.)
27

2.9.1 The 1…10 V dimming curve
The 1…10 V interface is defined in IEC 60929. In the control voltage
range of 3 V to 10 V there is a largely linear relationship to the relative
luminous flux. In the 1…10 V interface, a logarithmic response
(like the DALI units) is adjusted by a logarithmic potentiometer.
luminous flux in %
Control voltage in V
Figure 14: The 1…10 V characteristic: Luminous flux against control
voltage
The control current in the 1…10 V interface drops with increasing
control voltage. Unlike the DALI interface, this does not therefore remain
constant.

3 Additional characteristics of
dimmable electronic control
gears from OSRAM 9
3.1 OSRAM DALI/1…10 V ECG: Added-value through intelligent features
• Automatic lamp detection through intelligent multi-lamp operation
(reduction of the ECG type variety)
Lamps of the same length and different powers can be operated
on an ECG. Furthermore, there are special approvals for specific
ECG lamp combinations 10
• Dimming range to 1 % of the rated luminous flux (3 % in CFL)
• Ignition of the lamp at an ambient temperature of -25 °C
• Optimized lamp warm start within 0.6 s [including HF DIM]
• Temperature-dependent “cut-off” at dimmer settings > 80 %
Shutdown of the filament heating at dimmer settings > 80 % prevents
a permanent heating current through the lamp electrodes
during operation. This reduces the filament loading and the power
loss by approx. 2W
• Power reduction by the ECG at excessively high ambient temperatures
in order to protect the electronics ! Can be used in very
close, hot luminaires (operating life, increased light yield, simplified
safety approval)
• High T c
point values (T c
< 80 °C) enable operation at high ambient
temperatures (T a
values)
• Stable dimming operation also in amalgam lamps (CFL (IN) and
OSRAM T5 CONSTANT lamps) ! particularly suitable for use in
areas with low ambient temperatures (e.g. cool rooms, outdoors):
relative luminous flux > 90 % from 0 °C to 70 °C
• Intelligent power control upon detecting instabilities in the lamp circuit
(amalgam lamp start) – protects lamp/ECG
• Permanent Heat Mode (PHM) for lighting effects (permanent filament
heating, switch-on of the continuous lamp pre-heating by
digital command, not DALI standard): The PHM ensures that, at
a light value = 0 (switched off lamp(s)), the lamp electrodes are already
heated. A delay-free lamp start is therefore possible
• > 1 s on/off switching cycle in the PHM ! No restrictions
• 0.5 s < t < 1 s on/off switching cycle in the PHM ! 30 k
switching actions with T5, 100k switching actions with T8
• < 0.5 s on/off switching cycle in the PHM ! 15 k switching
actions with T5, 50k switching actions with T8
• Optimized filament heating and lamp operation at mains undervoltage
(no damage to the lamps)

• EEPROM for backing up settings/parameters even if the mains
supply fails
• Lamp replacement without mains reset (automatic lamp reactivation
after lamp replacement) [including HF DIM]
• DC operation in the input voltage range of 154-276V/lamp start
above 198V [including HF DIM]
• Optimized radio interference suppression: Maintaining the requisite
EMC thresholds with a comfortable safety margin for ease of luminaire
installation [including HF DIM]
• DALI standard acc. to IEC 62386 -101/-102/-201
• 1…10 V standard acc. to IEC 60929
3.2 OSRAM DALI ECGs and TouchDIM interface
To realize light controllers as economically as possible, the DALI ECGs
from OSRAM also have the integrated TouchDIM function 11 . It is therefore
possible to dim and switch DALI ECGs directly with mains voltage
on the DALI control terminals (TouchDIM Interface = TDI). Only
one commercially available switch is required, the ECG assumes the
control function.
The changeover between both operating modes – TouchDIM or
DALI operation – can only be realized after mains voltage. Hence, it is
not possible to switch between the operating modes via an integrated
safety mechanism during operation. Switching between both operating
modes can take place as often as necessary. TouchDIM must
never be used at the same time with a DALI control system.
TouchDIM offens all the functions of a comfort dimmer:
• Soft starting of the lamp (lamp starting at the lowest dimmer setting
(1 % (3 %), lowest luminous flux)
• Short press: On/Off
• Long press: Dimming
• Memory function (light value stored by double-clicking)
• All settings are remained even after a power outage
11
TouchDim is not part of the DALI standard
30

3.2.1 Wiring and line compensation
• The line lengths between buttons and the farthest away DALI ECG
should not be longer than 25 meters. Where line lengths over
25 meters are required, compensation methods (bell transformer,
resistor) must be used
• Do not use more than 6 DALI ECGs in one TouchDIM application
(up to 6 ECG can be controlled by one switch, the number
of operating points is limited to 2)
• Different lamp families should not be mixed because of the
different preheating times (e.g. HO lamps (500 ms starting time) vs.
HE lamps (700 ms starting time)
• If more than one operating point is required, a maximum of 2 buttons
per TouchDIM application can be switched in parallel
• The TouchDIM wiring must be rated for mains voltage (230 V)

Note:
• Only use switches without control lamp and with 230 V normallyclosed
contact as the permanent current through the glow lamp
can lead to malfunctions
• TouchDIM is not part of the DALI standard (IEC 62386), but rather
an additional OSRAM function
3.2.2 Operating parameters for TouchDIM
To operate the TouchDIM, AC voltages of 10…230 V (RMS) at
a frequency of 46…66 Hz can be used – there is no DC voltage
allowed.
3.2.3 Compensation of interferences
A control transformer which complies to the following figures and values
must be used with a total line length from the switch to the ECG of
25 m to 100 m in order to prevent interference (e.g. through capacitive
induction):
Primary 230 V/Secondary 12 V, transformer rating required: 25 mW

per ECG)

The option of connecting a conventional resistor is also available

3.2.4 TouchDIM operation
• Switching the lamp on/off: Short button press (< 0.5 s)
• Dimming: Long button press (> 0.5 s), (dimming direction changes
each time the button is pressed)
• Save the reference value in the switched-on condition: "Doubleclick“
(press briefly 2 x within 0.4 s)
• Delete reference value: Double-click with the lamp switched off
(ECG starts with 100 % luminous flux when switched on again)
Note:
Long button press with the lamp switched off: Lamp is switched on at
the minimum dimmer setting and, hence, remains highly dimmed until
the switch is released.
3.2.5 Operating modes with TouchDIM
With the QTi DALI, OSRAM offers two modes for TouchDIM that differ
in switch-on behavior (this refers to the software-controlled switching
on/off and not to the switching off of the voltage supply):
Mode 1:
The electronic control gear switches with the last dimming value that
it had before being switched off. The following applies:
Short press: Switching
Long press: Dimming/Switching on at minimum dimmer setting
12
For example: Vishay Beyschlag: MBA/SMA 0204, MBB/SMA 0207, MBE/SMA
0414 - Professional
33

Mode 2:
The electronic control gear switches on with the dimming value (preset
value) last stored by double-clicking. The following applies:
Short press: Switching
Long press: Dimming/Switching on at minimum dimmer setting
The following figure shows the options of both operating modes to the
user:

3.2.6 Asynchronism/Automation of the system
The increased use of DALI ECGs in button operation shows again and
again that in systems with
• not completely sinusoidal supply voltage (e.g. electronic dimmer on
the same mains supply),
• excessively long line lengths or
• high DALI ECG count (more than 6 ECGs per TouchDIM application)
increasing results in asynchronism of the connected DALI ECGs. To
consistently prevent asynchronously running lighting systems in practice,
the permissible number of DALI ECGs is limited to 6 units.
3.2.6.1 Prevention/Remedying of asynchronism
With the aid of the DALI repeater that is described in more detail in the
context of the LMS (Light Management Systems) portfolio (see
www.osram.com/ecg-lms), up to 64 ECGs can easily be operated in
the TouchDIM function without having to be concerned about asynchronism.
Without the repeater, the TouchDIM application is however
only restricted to floor-standing luminaires or small offices.
3.2.6.2 Synchronization
For physical reasons a TouchDIM can work asynchronously, i.e. the
switching status and dimming direction of the separate luminaires are
different. The following steps help in the synchronization of a Touch-
DIM system:
1st. step: Longpress (> 0.5 s)
! All luminaires switch on
2nd. step: Shortpress (< 0.5 s)
! All luminaires switch off
3rd. step: Longpress (> 0.5 s)
! All luminaires switch on and dim
4th. step: Double-click
! Save dimmer setting (if required)
After these four steps – long–short–long–double-click – the ECGs
again behave synchronously.
Note:
TouchDIM was developed for manual control and is not suitable for
automation, e.g. for connecting to a PLC.
36

3.2.7 Behavior after mains voltage failure
If the luminaire is disconnected from the mains, the ECG saves all
set values. If the light value has been changed before being switched
off, this value is restored, i.e. after a voltage loss, exactly the last
status is reestablished (instant switch-on to the previous present
luminous flux, no "intermediate path" above 100 % luminous flux and
subsequent dimming). All settings (dimming values, lamp on/off,…)
also remain intact with a prolonged mains voltage failure. By doubleclicking,
the stored reference value also remains in the ECG after a
power failure and can, if required, be called up again with the luminaire
on/off. If the luminaire was switched off at power failure, it also remains
off when the mains voltage is restored. For this reason, operation in
the TouchDIM mode is not suitable for centrally supplied emergency
lighting applications.
3.3 OSRAM DALI ECGs in emergency lighting applications
Due to the variety of emergency lighting control systems and applications,
this topic cannot be described in detail in this primer.
The integration and testing of the complete emergency lighting system
acc. to VDE 0108 must always be conducted by the persons responsible
for the overall system as the ECG is only one element of the
overall system. The VDE 0108 is a system standard and not an ECG
standard. There are special electronic control units on the market for
local emergency lighting applications with battery integrated in the luminaire.
The instructions described here for wiring and programming
the DALI controllers are based exclusively on central battery applications
and, hence, on standard DALI controllers (ECGs).
QUICKTRONIC INTELLIGENT DALI ECGs are suitable for emergency
lighting systems based on VDE 0108. All OSRAM DALI controllers detect
emergency operation (system failure level) if there is an absence
of voltage on the DALI input (16V DC in normal operation). This function
is part of the DALI standard and is supported by all vendors.
37

For emergency lighting/voltage loss 13 in the DALI controllers two values
can be configured/programmed separately for each unit (e.g. using
the OSRAM DALI Luminaire Tool DLT).
• System failure level: Emergency operation (1…100 % light), detected
by switching off the control line
• Power on level: Light value after the mains voltage is restored
(1…100 % light)
The system failure level always has priority over the power on level,
especially when switching over (in the event of a brief power outage,
emergency operation is therefore ensured). The factory setting
for both values is 100 % light.
Typical data for the QUICKTRONIC INTELLIGENT DALI family important
for emergency lighting systems are*:
Starting time of the lamp (max.)
Permissible voltage range (DC)
Min. voltage for lamp start (DC)
Permissible voltage range (AC)
Mains frequency
0.6 s
154…276 V
198 V
198…264 V
0, 50…60 Hz

*Further technical data of the respective ECG type can be found in the
corresponding datasheet or on our homepage at www.osram.com/qti.
The DALI or dimming function of the QTi DALI … DIM is identical in AC
and DC operation.
13
• During power outages < 200 ms, the light stays on (no light failure) because
the ECGs are not preheated again.
• During power outages > 200 ms, the ECGs go through the entire preheating
cycle. The following applies to the QTi DALI/DIM and HF DIM family: The
starting time in HO lamps is 0.5 s and in HE lamps it is 0.7 s. DALI ECGs
require an additional 0.5 s for initialization

The OSRAM DALI ECG (1) emergency lighting is supplied with AC
voltage via the central battery system. All electronic control gear can

For maintenance functions (e.g. for servicing, caretaker switching) the

via the monitoring module (2), the commands of the DALI controller (3)
(e.g. dimmer setting) are ignored.
A difference is now made between two cases when switching the
lighting system into emergency operation:
3.3.1 Mains failure at the subdistributor (UV)
In accordance with VDE 0108 when AC mains is present at the central
battery system (CB) in emergency operation, the system must not be
switched to battery but the security luminaires (1) must be switched to
permanent light. The external DALI controller is ignored, the OSRAM
DALI ECG (1) emergency lighting is dimmed to 100 % by the monitoring
module (2) using a DALI instruction set.
39

3.3.2 Mains failure at the main distributor (HV)
The central battery system (CB) provides DC supply voltage. The external
DALI controller (3) is ignored, the ECG is dimmed to a previously
defined value by the monitoring module (1), which is DC compatible,
via a DALI instruction set. The emergency lighting level is pre-specified.
OSRAM DALI ECGs (1) can communicate DALI and, hence, be
individually dimmed by applying a DC voltage supply.
3.3.4 DC emergency operation of the lighting system without monitoring module
The DALI controller (3) is switched off with switchover to the emergency
operation of the lighting system. Through the absence of the
DALI voltage (approx. 16V DC that is always present during normal
operation on the terminals of the DALI controllers), the DALI controllers
(4) detect that the "System Failure Level" must be set.
Note:
The "System Failure Level" has priority over the Power On Level, i.e.
if the DALI voltage is absent when applying the supply voltage to the
ECG, the System Failure Level will be set.
The "System Failure Level" can be configured individually for each
ECG – from 0…100 % light.
3.3.5 QTi DALI: Benefits in emergency lighting applications
• Unrestricted DALI communication to the ECG even in emergency
operation of the lighting system
• The luminous flux factor can be freely adjusted during battery
operation and, hence, matched to the illumination situation
• Efficient utilization of the battery capacity through reduced luminous
flux maintenance
• Simple installation in the luminaire
• Use of DALI ECGs as emergency lighting ECGs with unrestricted
luminance flux reduction also possible without bus
3.4 OSRAM DALI LUMINAIRE TOOL (DLT)
The OSRAM DALI LUMINAIRE TOOL (OSRAM DLT) is a testing and
programming tool for luminaries with DALI controllers. All functions
(except for the individual OSRAM serial number Chip Identification
Number (CIN)) correspond to the DALI standard and are hence vendor-independent.
40

The functions of the OSRAM DLT are:
• Luminaire function test (for production)
• Reading of all DALI parameters (e.g. in the event of complaints)
• Preprogramming of all DALI parameters (e.g. for projects)
• Reading and printing of the unique OSRAM operating unit address
(OSRAM-ID ! CIN (Chip Identification Number)) of each
QUICKTRONIC INTELLIGENT ECG and printing on barcode
(128-bit) for simplified system commissioning
o Placing the label on the luminaire
o Max. 4 ECGs in a luminaire
o Purpose/Advantage
- Simplified installation of a DALI system (no flashing, start-up
from outside)
- No predefined position of the luminaire (position defined with
ID in the luminaire plan)
- System integrator: Assignment of the ID to the position
Figure 22: Reading and printing of the unique OSRAM control unit
address on barcode
The following section of the software interface shows the DALI parameters
that can be configured by the DLT. Special attention is drawn
here to the "System Failure Level" and "Power On Level" which come
into play for use in emergency lighting systems:

3.5 Basic switching actions of 1…10 V control gear
The simplest type of light control can be realized via an appropriate
logarithmically-dimensioned potentiometer (available from the electrical
trade). Because the control power of the OSRAM DIM ECG is
generated by the ECG itself, the resistance value is dependent on the
number n of the connected ECG. It can be calculated according to
the formula:
100 kΩ
log
R Poti
=
n
If the calculated value is not contained in the resistance table, a similar
value should be selected as otherwise full modulation of the lamps is
not possible (this overdimensioning may possibly lead to the fact that
the whole rotation angle of the potentiometer for the brightness control
cannot be used). The potentiometer must be designed for at least
a power of P Potentiometer
= 2.8 mW · n.
A mains switch is also required for switching the lighting system. When
connecting the potentiometer, it is important to note that the full lighting
level is reached by turning to the right. When connecting more
than 2 OSRAM DIM ECGs, it is recommended to use a DIM MCU
manual control. Detailed information on this can be found in the relevant
documentation (LMS portfolio, see www.osram.com/ecg-lms).

3.5.1 1…10 V: Staircase operating modes
As a basic principle, frequent switching is not ideal for fluorescent
lamps and compact fluorescent lamps. Hence, bulbs are
still used in applications with extremely high switching frequency
despite the high energy consumption. In staircase operation,
OSRAM DIM ECGs dim the light (1 % luminous flux) when it is not
required. This avoids unnecessary switching operations and saves
energy. Further benefits of the staircase circuit: Because the light is
not completely switched off, a certain amount of light still remains
available as an orientation light. When needed, the full light is immediately
present, without having to wait for a preheating period.
Typical applications of the standby circuit are all applications with high
operating cycles, such as staircase, hallway or underground carpark,
especially when the light is controlled with motion detectors or
timer switch.
3.5.1.1 Applications
a) Stairwell lighting timer switch
Here a special stairwell lighting timer switch (e.g. Siemens: Type 5TT1
303, see Siemens Catalog) provides the readiness switching of the
OSRAM DIM ECG. Functionality: The stairlight timer switch switches
on the OSRAM DIM ECG at the push of a button (100 % light). After
max. 10 min (time can be adjusted) the light is lowered to a preselected
level without intermediate stages. After a total of 30 min it is
switched off entirely. This 30-min cycle can be restarted at any time
by pressing a switch. Thus, the lamp-protecting mode is employed
in the evening hours when the staircase is used more frequently. The
light only switches between the dimmer settings, real switchings are
infrequent. At night, when the stairwell lighting is not required for prolonged
periods, the remaining 13 % energy consumption are also still
stored at the lowest dimmer setting.
43

Figure 25: Stairwell lighting timer switch
b) Stairwell lighting timer switch and motion detector
Because the button engages the line voltage (L), it can be replaced by
a motion detector. Parallel switching with the switch is also possible.
Because the switch-on time is set on the stairwell lighting time switch,
the switch-on time of the motion detector can be set to a minimum.
Figure 26: Stairwell lighting timer switch and motion detector
44

3.5.1.2 Control via analog output
The external control with an analog output 0…10 V (e.g. PC card)
is basically possible. This control module must be capable of taking
the current supplied by the ECG in the control line and of reducing
the control voltage to at least 1 V. For that reason, however, the analog
output must fulfill two requirements: It must be potential-free and
may not therefore be connected galvanically with touchable parts or
circuits that are subject to SELV requirements (test voltage 2500 V,
the test voltage to grounded parts is 1500 V). The analog output can
operate as a current sink because it must take the control current of
the OSRAM DIM ECG. Mostly, it is not known whether and how much
current an analog output can take but assistance can always be provided
by an interface circuit.
3.5.1.3 Interface circuit
In the case of up to three OSRAM DIM ECGs, it is recommended to
connect the control inputs of the ECG directly with the analog output
(e.g. PC card) and, in the case of four and more OSRAM DIM ECGs,
to interconnect a signal amplifier. Then start up the system, set the
control voltage to 0 V and check with a multimeter directly at the analog
output. If the measured value is less than 1 V, the situation is okay
and the system can be started. If the control voltage here is greater
than 1 V, the analog output cannot take enough current and an additional
current sink is required in the form of a parallel switched resistor
R. The required value is determined as follows: At a default control
voltage of 0 V, a potentiometer (approx. 5 kΩ linear) is also set on the
analog output and a 1 V control voltage set with it. Disconnect the potentiometer
and measure the resistance value (must be greater than
680 Ω), provide and connect corresponding fixed resistor (construction
form 0207, power rating 0.25 W, possibly next smaller resistance
value).

3.5.1.4 Control via instabus EIB
Dimmable ECG with 1…10 V interface can be easily integrated in
installations with the instabus EIB building control system. The link between
EIB and the dimmable lighting system is a switching/dimming
actuator. A switching/dimming actuator is required for each lighting
group. The digital bus signal is converted by the switching/dimming
actuator into the analog 1…10 V control voltage for OSRAM DIM
ECGs. The ECG is switched on/off by an integrated relay contact.
Different functions can be parameterized: on, off, brighter, darker, as
well as a default defined control voltage. Sensors for daylight control
etc. are normally connected at the instabus level. Detailed information
is available from manufacturers of the instabus EIB.
3.6 Special wiring diagrams, tips and tricks
3.6.1 Temperature-dependent control
The recognized temperature problems in dimmed fluorescent lamps
can be resolved by a temperature-dependent lower limit of the dimmer
setting.
The latest generation of the QTi DIM (as of the end of 2008) does this
automatically. For older versions, the following implementation applies:
The stability threshold (stable dimming operation at low temperatures
(< 10 °C)) depends greatly on the lamp tolerances. In control types
where the lamp starts at 100 % (e.g. stairwell switching), the temperature
limit can be lower. Therefore, in an automatic control both the
response temperature and the control voltage should be adjustable.
The following circuit is recommended:

Figure 28: Temperature-dependent control
46

The temperature controller can be a room temperature controller for
heating control, for example. The switching temperature (e.g. 0 °C)
should be as precisely adjustable as possible. The switch must be a
closer, i.e. must be closed at high temperatures. Such appliances are
offered with a bimetal contact (e.g. 2NR9 090-1, power supply not
required) or with a temperature sensor (e.g. 2NR9 078, power supply
required). Any existing heating resistors for thermal feedback (RF)
or nighttime temperature reduction (NA) are not connected. The only
power supply line is the possibly required power supply. Depending
on the application, different protection types are necessary. Further
details are available from specialist personnel for heating and air handling
units.
3.6.2 Limitation of the control voltage
For certain applications, it is necessary to set an upper or lower limit
of the control voltage for the OSRAM DIM ECGs. Reasons for this can
include special lamp-ECG combinations and occurrence of flickering
at lower temperatures, for example.
a) Upper limit
The simplest option of dealing with this is the parallel switching of a
Zener diode with the corresponding value. For a limit of 7 V, for example,
a Zener diode with the nominal value of 7 V or a value close to
this must be used. (Zener diodes are available as the E24 series. The
type Bzx 55C xVx is recommended. For example, for xVx a value of
7V5 = 7.5 V must be taken. At least 20 ECGs can be controlled with
this type.) As a general rule, for parallel switching of several control
units the control unit with the lowest value applies as the default for
the OSRAM DIM ECG. This applies for all passive control units, i.e.
units that acts as a current sink.

) Lower limit
An effective lower limit can be realized by a series connection of 2
control units. The sum of the two units is effective. With one unit,
the default control voltage of the other unit cannot be undercut. Attention:
In a series connection, two control units (e.g. DIM MCU) is
the smallest achievable control voltage approx. 2 V (~= 4 % luminous
flux) connections must be realized according to the diagram.
Figure 30: Lower limit of the control voltage
3.6.3 Line length of the 1…10 V control line
The control line length is only limited by the drop in voltage. It can
generally be said that a line length of 100 m is completely noncritical.
For a more precise estimate, the following formula can be used:
For example, with 1.5 mm², strip of luminaires, supply at the beginning:
L max
= 35 km/no. of ECGs
= 350 m for 100 ECGs
= 700 m for 50 ECGs
Systems of any size can be realized with DIM SA signal amplifiers.
3.6.4 1…10 V DIM ECG and emergency lighting
QUICKTRONIC DIM is suitable for emergency lighting systems in accordance
with VDE 0108. If QUICKTRONIC ® DIM are used in emergency
lighting systems, the control line should be disconnected by
suitable measures at the plus pole during emergency operation. Corresponding,
simple-to-wire changeover converters that pass on a
presettable control voltage to the OSRAM DIM ECG, thereby enabling
battery-saving emergency lighting operation at less than 100 % luminous
flux, are commercially available.
48

Figure 31: Emergency lighting with 1…10 V DIM ECG
It must be noted that some accessory components (e.g. DIM SA signal
amplifiers) are not approved for battery operation. Therefore, it is
important to make sure that these components are never connected
to DC voltage. In this case the signal amplifier, for example, constitutes
a fixed resistance that is connected to the control line. The dimmer
setting of an ECG is then around 20 %, and accordingly higher
for more than one.
3.7 Terminals/Cable cross-sections/Wire stripping lengths
For the combined terminals used in the QTi DALI/DIM for T5 and T8
fluorescent lamps, both solid lines as well as flexible lines are permissible.
The contacts of the terminal can be made at the top via a socalled
insulation displacement contact and via a plug contact (wire
stripping length 8.5-11 mm). Likewise for ECGs with push terminals
(HF DIM, QTi T/E DALI/DIM), both solid lines (wire stripping length
8.5-9.5 mm) and flexible lines are also permitted provided these are
tinned, ultrasound welded or fitted with wire-end sleeves.

3.7.3 Basic insulation
IEC 61347 demands basic insulation between the control circuit and
mains supply for control inputs. The DALI standard (IEC 62386) is
related to this. Consequently, the DALI line is “only” basically insulated
and must be treated like the mains voltage for this reason as is the
1…10 V interface.
3.7.4 Lamp holders
The lamps must be mechanically secure and make contact in the
lamp sockets. The holders must be selected according to the type of
ECG/lamp used.
3.7.5 Master/slave circuit
(2-lamp ECG for the operation of 2 single luminaires) Master/slave operation
with multilamp dimmers is not permitted. This is because of
the capacitive leakage currents that can lead to imbalances, different
luminances and unstable operation in the dimmed state (flickering).
3.7.6 Minimum reflector gaps
The reflector must never rest on the lamp, otherwise this can lead to
vibrations and noise emissions. A minimum gap of 6 mm must be
maintained between the lamp and the reflector in all luminaires. If the
gap is less, this can lead to different brightnesses along the length of
the lamp due to the capacitive leakage currents. Flickering can also
occur.

increases excessively for cold HO lamps lies just below the 30 % dimmer
setting. For HE lamps, this point is reached at the same power
density. Because of the 100 % power being approx. only half as
high, the dimmer setting is 60 % here. The HO49 lies between HE
14…35 W and HO 24…80 W/Dimming of the amalgam lamps T5 HO
CONSTANT (24 W, 39 W, 54 W, 80 W), CFL (DL CONSTANT 40 W,
55 W, 80 W and T/E IN PLUS 26 W, 32 W, 42 W, 57 W) is possible.
The temperature range of the luminaires can be expanded downwards
by raising the lowest dimmer setting until the light has reached
a higher inner temperature, otherwise flickering or/and starting problems
of the lamp can be expected. From the end of 2008 units do this
automatically.
3.8.1 Intelligent thermal management in hot luminaires
Intelligent thermal management enables operation in a wide ambient
temperature range through power reduction.
From the generation at the end of 2008, the QTi (DALI)…DIM ECG
from OSRAM include the feature of intelligent temperature regulation.
Features
• Notable increase in the light yield (lm/W) of hot luminaires
• Virtually no loss of luminous flux (lm) compared with uncontrolled
operation
• No reduction in the service life of the ECG within the control range
• Simplifies the safety approval of hot luminaires
• Relieves luminaire components
52

Note:
• Limits the t c
temperature to < 80 °C (depending on installation condition),
but never switches the ECG due to excessive temperature
• Thermally problematic luminaires do not necessarily become standard
conformant devices, even with these ECGs
• Power reduction is carried out up to 50 % of full load operation
Functionality
The ECG measures the ECG temperature once per minute. At the
selected limiting temperature it begins to reduce the power in order to
lower the temperature of the luminaire and to prevent the temperature
of the ECG from increasing further. The T c
temperature lies between
75 °C and 80 °C depending on installation conditions (e.g. heat coupling
into the ECG from top or bottom).
A reduction of the system power by 10 %-20 % at an ambient temperature
of 25 °C is sufficient in most cases even in hot luminaires,
however, only approx. 1 %-2 % light is lost because the level of efficiency
of the system increases.
Dimming is always possible the temperature regulation may affect
the upper dimming level only significantly.
!
The regulation of the lamp power compensates the loss of light
output in hot luminaires.

Why are the light losses so small due to the temperature limitation?
Assuming a luminaire whose inside temperature (= lamp ambient
temperature) is to be lowered from 65 °C to 55 °C. A reduction of
the system power by 20 % is required for this. The diagram shows the
Φ(T) curves of T5 lamps for 100 % and 80 % system power.
During the transition from the 100 % curve to the 80 % curve and the
lowering of the lamp ambient temperature by 10 °C, the luminous
flux remains roughly the same.

QTi (DALI)…DIM never stop thinking: Instructions for the thermal
coupling of lamp and ECG
!
Temperature limitation is control engineering in the classical sense
and requires, therefore, a closed control loop: The lamps must be
able to heat the ECG. This is ensured when the ECG and lamps are
housed in the same luminaire space, separated by a reflector if necessary.
If the ECG is mounted outside the luminaire, it cannot exploit the benefits
of the thermal managment.
55

3.8.2 Color temperature
Between the maximum and minimum luminous flux of the lamp the
color temperature of the lamp changes – in a DULUX L this is approx.
150 Kelvin. Due to the great difference in luminance density, the color
difference appears to be visually considerably greater. As a result, the
subjective perception of the human eye does not reflect the objective
color temperature change. Directly after changeover from maximum
to minimum luminous flux, a temporary color displacement of up to
400 Kelvin occurs (displacement to the red end that decreases after
approx. 30-40 minutes to the color difference mentioned above (stabilization
phase)).
Figure 40: Color-phase diagram acc. to DIN 5033
Note:
Measurement of the most similar color temperature with greatly
dimmed lamps places the highest demands on the electronics and
receiver of the color measuring device. Incorrect valuations cannot be
excluded with conventional color measuring devices.
3.8.3 Outdoor applications
For applications out of doors a special OSRAM housing, the
“OUTKIT”, is available for protecting the ECG against humidity. It is
available for ECGs with a headroom of 30 mm or even 21 mm, in the
lengths of 360 mm and 423 mm. Details of this can be found in the
current light program. For outdoor applications the temperature range
of the system lamp-ECG should be examined in detail. In all outdoor
applications attention must be paid to sufficient mains quality (above
all, lightning protection) so that the ECGs are not damaged.
56

3.8.4 Functional test of luminaires
The dimmable QTi family from OSRAM (DALI and 1…10 V) gives in
the luminaire test (with 10 Ω filaments) the following power per lamp:
1-lamp/2-lamp (T5 and T8): 32 Watts
3-lamp/4-lamp (T5 and T8): 16 Watts
This function is independent of the deployment of the actual lamp.
For special applications/luminaires, the filament detection can be
switched off – details on request.
If the end test of the luminaire is carried out in TouchDIM mode,
note that the lamp must be dimmed to 100 % light before the disconnection
of the luminaire from the mains supply . Only in this way is
it ensured that the light can also be switched on with the protection
(without control unit) (DALI standard) during installation of the luminaire.
If the luminaire was switched off via TouchDIM the luminaire
also remains off after a loss of voltage – the installer could mistakenly
assume a defective ECG in this case.
If the luminaire has mains voltage applied to it for the first time (without
control unit), it must be switched on with 100 % luminous flux (= DALI
factory setting). The changeover of DALI to TouchDIM mode or vice
versa, assumes a mains voltage failure of the ECG (safety interlock).

Functionality of QTi DALI/DIM: Power boost and amalgam
lamps
HO 39 W CONSTANT
The amalgam releases just as much mercury as is required for the
discharge and, as a result, considerably decreases the luminous flux
at high or low temperatures. After a change of the operational mode,
however, it takes a number of minutes until the mercury balance is
discontinued again. If the lamp is switched off for a prolonged period
– no discharge and no mercury requirement – the amalgam collects
all the mercury. On a restart, therefore, there is initially a lack of
mercury which can be detected by the "pink phase“.
If the lamp is dimmed at the same time, its maintaining voltage can
rise to non permitted values and the discharge can become instable.
Here the power boost of the QTi DALI/DIM comes into play: It
automatically increases the lamp power in order to lower the
lamp voltage and to stabilize the discharge phase. Then when
the amalgam has released enough mercury, the lamp power is automatically
reduced again and the lamp can be dimmed normally.

Also in normal mercury lamps the power boost takes effect and
simplifies dimming during the ignition phase of the lamps as well as for
very low temperatures:
When there are instabilities in the lower dimming level, the Power
Boost regulation helps to stabilize the burning conditions.

Functionality of QTi DALI/DIM: Relative luminous flux > 90 %
over an additional expanded temperature range from 0 °C to
+70 °C
Mercury T5 lamps reach their luminous flux optimum at an ambient
temperature of 35 °C – but only if their mercury household is not
influenced by additional electrode heating. The QTi DALI/DIM units,
therefore, have a cut-off, i.e. the electrode heating is switched
off when it is not needed.
Neu! New!
It can be shown that, at low ambient temperatures, amalgam lamps
give off more light when the electrodes are heated somewhat.
At high temperatures, however, this effect is reversed. The QTi DALI/
DIM uses its internal temperature sensor in order to switch off
the electrode heating at a sufficiently high temperature.
This means a further increase of the luminous flux of cold amalgam
lamps is achieved: The temperature at which the luminous flux
falls below the 90 % line drops from +5 °C to 0 °C.

3.9.1 Dynamic dimming procedures with amalgam lamps
The frequency of dimmer setting changes is primarily limited by the
inertia of the control input, a passage of the dimming range takes approx.
200 ms for 1…10 V, and approx. 50 ms for DALI. Thus, rapid
flashing blurs to a middle dimmer setting. At 10 Hz, this effect is already
particularly visible at 1…10 V. No damage to the lamp is to be
expected. A dimming process every 2 s is possible without any problem.
60

3.9.2 Benefits of amalgam technology
Note:
Dimming of amalgam lamps is also suitable for outdoor applications.
Sufficient attention should be paid that the ECG is protected against
external influences (IP67).
Figure 44: Relative luminous flux against ambient temperature in the
luminaire of T5 standard and T5 HO CONSTANT lamps
Figure 45: More light from new luminaires thanks to amalgam technology
61

Note:
• Amalgam and mercury lamps must never be mixed in multilamp
ECGs because the power increase available in amalgam lamps
would lead to a vigorous overshooting of the light in a mercury
lamp. In addition, the synchronization in the lower dimming range
would be poor.
• No release: Dimming of a T5 amalgam lamp with predecessor
units up to the end of 2008 (DALI and 1…10 V):
• For dimmer settings below 30 %, the following applies:
- Voltage peaks arise through unwanted controller oscillations 14
- Unfavorable operating condition leads to lamp flickering and a
reduction of the lamp service life
• Recommendation: Dimming of amalgam lamps is possible,
but this is not released by OSRAM. Burning-in of the lamps
at 100 % luminous flux after each restart for approx.
2-3 minutes, then dimming. In principle, however, dimming of
T5 amalgam lamps with predecessor units is not recommended
for the reasons mentioned above.
14
Oscillations – typically in the lower third of the dimming range – can develop
when fluorescent bulbs with electronic control gear are dimmed, which are
caused by the interaction of lamp characteristic, lamp time constants, resonant
circuit and control.
62

4 System energy consumption
and dimmer setting
Because there is a largely linear relationship between the power
consumption of the DALI/DIM systems (lamp and ECG) and the dimmer
setting, the power consumption PN(d) can be calculated for
each dimmer setting d (in percent) from the values PN100 % (100 %
nominal power, PN = Power Nominal) and PN1 % (nominal power of
1 %) (depending on ECG lamp combination, available on request):

Numerous applications in the downlight sector can be covered by
one luminaire type in combination with the new QTi T/E DALI/DIM
generation from OSRAM. Thus, for example, it is possible to design
the lighting of a building with different room heights and different
luminaire installation locations (e.g. corridors, foyers etc.) so they are
simple and flexible to dim. Thus, several “lumen packages" are possible
for each room. Due to optimized filament preheating, the lamp
starts inside 0.6 seconds which means the user does not have to
accept unnecessary waiting periods after switching on.
The intelligent QTi T/E DALI/DIM units automatically adjust the filament
preheating for very low temperatures. Thus, amalgam lamps
can be operated in a stable way.
Intelligent power reduction at excessive temperatures ensures a
high service life and reliable operation.

6 The Activity Group DALI
(AG DALI)
The “DALI" workgroup was set up in 1999 under the auspices of the
ZVEI (the German Central Association of Electrical Engineering and
the Electrical Industry) with the aim of establishing this new standard
on the market. All the leading manufacturers of ECGs and controllers
are represented in this Activity group so they can develop and market
their products in accordance with the requirements of the DALI standard.
The AG DALI is an open community that any company can join
for a modest annual fee.
The AG DALI has published a “DALI Handbook” and various other information
brochures that can be downloaded from their home page.

8 Frequently asked questions
(FAQ)
8.1 DALI part
8.1.1 TouchDIM
• Can the TouchDIM function and a DALI controller be used at
the same time?
No. Either a DALI controller or the TouchDIM function! TouchDIM
and DALI operation are mutually exclusive.
• How do the ECGs behave after a mains voltage failure?
The DALI ECG of the QTi series automatically reestablish the previous
status. Both the switching status (on/off) and the dimmer setting
are taken into account here.
• Can devices that do not run synchronously be synchronized
again?
Yes. The procedure is as follows:
Press switch for long period (> 3 s) (all ECGs on).
Press switch for short period (all ECGs are switched off).
Press switch for long period (all ECGs switch on with minimum
dimmer setting and then fade up) ! Long – short – long
• Is it also possible to connect more than one DALI ECGs to a
switch?
Up to 6 ECGs can be controlled by one switch, the number of control
sections is limited to 2. With one DALI repeater, up to 64 DALI
ECGs can be operated in TouchDIM mode.
• How long should the cable be between the switch and the
ECG?
The line length should not exceed 25 meters. In the case of longer
lines, additional measures must be taken in order to suppress interference
(e.g. bell transformer).
• Which switches can be used?
All button can be used that are suitable for mains voltage, but no
button with glow lamps.
• Does TouchDIM only work with 230 V AC voltage?
No, TouchDIM control is possible with AC voltages between 10 V
and 230 V (effective value!).
• Can I also use DC voltage for TouchDIM?
No, it must be AC voltage with a frequency between 46 and
66 Hz.
72

• Can a TouchDIM system be upgraded with a DALI controller?
Yes, an upgrade is possible at any time. Changeover of the DALI
ECGs from TouchDIM to DALI takes place automatically after a
power outage on the ECG when the first DALI command is sent.
TouchDIM and DALI control cannot be used at the same time!
• Can the motion function of the TouchDIM sensor be
switched off (holiday mode)?
Yes, the so-called "holiday mode" prevents the lighting system being
switched on by the motion sensor. It is activated by doubleclicking
on the switch if the light has not been manually dimmed in
the previous 30 seconds. The motion function is active again if the
luminaire is switched on manually at the switch.
8.1.2 DALI in general
• Do the ECGs have to be addressed in DALI?
No, it can also function without addressing (broadcast mode).
• What is the difference between DSI and DALI?
DSI is a corporate solution, not a general standard like DALI. DSI
does not allow digital addressing so it is not possible to form
groups freely or check individual lamps for faults! Groups have to
be formed by wiring as well as in the case of 1…10 V systems.
• Does attention have to be paid to the group arrangement in
DALI when wiring the system?
No, the groups are generally assigned (addressed) when the system
is started up.
• Does attention have to be paid to the polarity of the DALI
control line?
When OSRAM DALI control gear is used there is no need to worry
about polarity.
• How can DALI ECGs be addressed?
They can be addressed individually, in groups or all together.
• Can I get feedback messages from DALI ECGs?
Yes, all device settings as well as the device status, such as lamp
faults, can be checked.
73

• Can a DALI ECG belong to more than one group at the same
time?
Yes. Each DALI controller can belong to up to 16 groups.
• Where are the data for the group assignments and light
scene values stored?
They are stored directly in the internal EEPROM of the ECG.
• Are the data in the ECG lost if there is a power failure?
No, the data are permanently stored in the ECG. They are retained
even if the power failure is prolonged.
• What happens if an ECG fails?
The ECG simply has to be replaced and adjusted to the appropriate
settings (the procedure depends on the control unit).
• What happens if a control unit is faulty?
If the DALI interface voltage is lost, all ECGs take on the so-called
"system failure level" (ECG factory setting: 100 % light).
• Can DALI be integrated in superordinate building management
systems (e.g. EIB or LON)?
Yes, by using gateways or control units with the appropriate interface.
• Is DALI a competitor to EIB or LON?
No, DALI is only a subsystem of the building management system
for controling the lighting.
• Can 1…10 V components also be incorporated in a DALI
lighting control system?
Yes, by using DALI to 1…10 V converters.
• Can existing 1…10 V lighting systems be upgraded with a
DALI controller?
Yes, a DALI to 1…10 V converter is needed for each 1…10 V luminaire
group (e.g. DALI CON 1…10 SO).
• Can the wiring of the DALI ECG be checked on a building
site?
This depends on the control unit used. DALI ECGs that are still in
their factory setting always produce 100 % light when the mains
voltage (with protection) is applied.

• What insulation is required for the DALI control line?
The DALI control line must be approved for mains voltage (as in the
case of the 1…10 V interface).
• Can existing 1…10 V control lines be used?
Yes, provided they are rated for mains voltage.
• How long can a control line be?
A maximum of 300 m between the controller and the furthest connected
DALI unit.
• Can control and power cables be laid together?
Yes, a 5 x 1.5 mm 2 NYM cable can be used, for example.
• What line cross section must the control line have?
Up to 100 m: min. 0.5 mm 2 /from 100 m to 150 m: 1.0 mm 2 /from
150 m: 1.5 mm 2 .
• Can any company develop a DALI controller or DALI ECG?
Yes, there are no restrictions except that the DALI logo
may only be used by members of the DALI Activity Group.
See also http://www.dali-ag.org/.
• What happens if I use DALI ECGs from different manufacturers
in the same system?
The controllers are DALI-compatible if they carry the DALI logo. It is
important to note, however, as in 1…10 V technology, ECGs from
different manufacturers can result in different filament preheating
times and different lamp starting times.
• Can controllers from different manufacturers be combined?
No, DALI ECGs are interchangeable, but the control components
cannot normally be combined.
• Is it possible to limit the maximum and minimum luminous
flux?
Yes, these values can be changed/limited with the appropriate
controller in the ECG.
75

8.1.3 DALI to 1…10 V converter
• Is it possible to switch and dim
with DALI to 1…10 V converters?
Yes, with the converter both are possible.
• Can the converter also offer the TouchDim function?
Yes, the converter behaves like a DALI ECG here in TouchDIMmode
1.
• Why does the converter have characteristic changeover?
So that it is possible to compensate for the different behaviours
of incandescent lamps and fluorescent lamps. You should therefore
choose between the linear characteristic (incandescent lamps)
and the logarithmic characteristic (fluorescent lamps) depending on
whether the converter is operating a fluorescent lamp ECG or a
dimmer for incandescent lamps).
8.1.4 Troubleshooting TouchDIM mode
Before you start troubleshooting, please check each time that the
controller is wired according to the operating manual and that the corresponding
power supply is on. In the case of luminaires, please also
check the light sources and replace if necessary.
• The ECG are not reacting as expected to switch operations.
If the button was pressed too long (> 1 second), the lamp starts
at the lowest dimmer setting which may be difficult to see in bright
ambient surroundings.
• Individual luminaires have a different brightness level and
conflict with one another.
→ Manual synchronization of the system:
Long button (>3 s) press (all lamps on).
Short button press (all lamps are switched off).
Long button press (all lamps switch on at minimum dimmer setting
and dim upwards).
• The ECGs react without any button being pressed.
1. The line between button and luminaire (ECG) is possibly too
long.
2. A button with glow lamp was used which is not permissible.
• The motion detection function of the TouchDIM sensor is
not working.
1. The luminaire was switched off by double-clicking the switch
and this has deactivated the motion detection function (holiday
mode)
76

2. The available daylight is sufficiently bright. Cover the sensor and
observe the response of the luminaire.
3. The motion detection is deactivated for 30 s after the lighting
system has been switched off manually. This time will only expire
if there are no more people in the detection zone.
• The luminaire is not regulating its the brightness to the setpoint
value
1. After setting the brightness, you must press the button twice
inside 30 s (to store the setpoint value). If you press the button
later than that, the holiday mode will be activated.
2. The dimming was carried out manually – this deactivates the
brightness control. Switch the luminaire off and on again.
3. No setpoint value has been stored.
Set the required light value and double-click to store it.
• Holiday mode cannot be activated.
The brightness level has been changed within the past 30 seconds
– holiday mode can only be activated after this time.
8.1.5 Troubleshooting DALI controllers
• The ECGs are not reacting to commands from the controller?
Please check the wiring where approx. 16 V DC
should be applied to
the DALI terminals of the ECG.
8.1.6 DALI to 1…10 V converter
• Not all lighting strips can be switched off.
Please check that the power supply of the relevant lighting group
has been routed via the load contact of the respective converter.
8.2 1…10 V DIM ECG part
• How long can the 1…10 V control line be?
The maximum permissible length of the control line is 100 m (also
applies to the DALI control line). (Note: Due to the low control current,
a drop in voltage is only noticeable on the control line after
approx. 300-400 m)
• What line cross section should the 1…10 V control line
have?
1.5 mm² is recommended as the cross section. The insulation of
the line used must be designed for mains voltage.
77

• Can control and supply lines be laid together?
Yes, control and supply lines can be laid together (VDE 0100 520
Section 528.11). The following points must be noted:
• The lines used must comply with the maximum operating voltage
that occurs. (VDE 0100/11.85, T520 Section 528.11)
• When laying core lines in installation ducts or channels, only the
conductor of a main current circuit, including the associated
auxiliary circuits, may be laid.
• Also a number of main current circuits, including the associated
auxiliary circuits, can be laid in one line. (VDE 0100/11.85, T520
Section 528.11)
• How can permanently selected lighting levels be controlled
simply and economically?
A simple control for preset lighting levels with 100 % or 1 % luminous
flux and several values lying between is possible with fixed
resistors or Zener diodes.
• Can 1…10 V dimmable ECGs from OSRAM be used for emergency
lighting?
Yes, but the use of dimmable ECGs in systems for emergency lighting
is associated with additional expense. Components such as
signal amplifiers, ICM 10 or the light constant holding module would
be destroyed by supplying them with DC voltage. This means that,
in the case of switching over to a DC voltage supply, these components
must be disconnected from the mains supply.
• Can compact fluorescent lamps with a 2-pin base be
dimmed?
No, ECG operation of 2-pin lamps is not generally allowed. The
glow igniter integrated in the base can lead to problems such as
poor, unreliable ignition, reduced lamp service life or destruction
of the ECG. Here additional heating of the lamp electrodes is not
possible in dimmed operation which would lead to a significantly
reduced lamp service life. Basically, only 4-pin base lamps with the
designation /E (e.g. DULUX S/E, D/E, T/E) can be operated on the
ECG and dimmed with this.
• Does continuous operation in the lowest dimmer setting
have an effect on the service life of fluorescent lamps?
Long-term operation of fluorescent lamps and ECG from
OSRAM in the dimmed state has no negative influence on the service
life of the lamp.
78

8.2.1 Troubleshooting 1…10 V
• Lamp does not burn with 100 % luminous flux
The control line is not connected or not correctly connected to the
control unit, or the control unit is not a sufficiently good current sink
and, hence, cannot reduce the control voltage.
Check the wiring. Check that the control voltage is reduced while
dimming and, if necessary, install a parallel resistor in the control
line.
Also one or more control inputs may be pole reversed:
• Disconnect control unit
• Subdivide control circuit
• Further subdivide control circuit
• Lamp always burn at minimum brightness
+ and - connectors of the control line are reversed, or short circuit
in the control line.
Connect lines with correct polarity, check wiring
• The lamp does not show the required luminous flux when
controlled with potentiometers or fixed resistors.
Potentiometers or resistors are wrongly dimensioned. Check the
values
• Insufficient brightness along the lamp
Spacing of the reflector to the lamp is too small, capacitive discharge
currents occur.
Increase gap between the reflector and the lamp
• Synchronous lamp flickering
Fault is outside the dimming system, e.g. N conductor disconnection,
control voltage not OK
Check N conductor connection and control unit

9.1.1 Minimum B/C characteristic triggering levels
The minimum triggering levels increase from B to C characteristic by
the factor = 1.67, i.e. not quite a factor of 2. At the same time, however,
the total current must not exceed the value of the automatic
cutouts.

9.2 DALI fade time and fade rate
The fade time can be set to any of 16 different steps (0 to 15) and
denotes the fade time to go from one scene to another (room lighting
states). The fade rate, which can also be set to any of 16 settings,
is the number of fade steps per second and acts on the speed with
which the lighting is faded up or down manually.

9.5 Energy classifications
In accordance with the CELMA classification scheme, the following
classes to which the typical controllers belong are available:
• Class A1: Dimmable electronic control gear
• Class A2: Electronic control gear with reduced losses
• Class A3: Electronic control gear (ECGs)
• Class B1: Magnetic control gear with very low losses
• Class B2: Magnetic control gear with low losses
• Class C: Magnetic control gear with moderate losses
• Class D: Magnetic control gear with very high losses
Dimmable ECGs are classified as A1 if they meet the following requirements:
• At a light power setting of 100 %, the ECG meets at least the requirements
according to A3 (OSRAM DIM ECG meet A2)
• At a light power setting of 25 %, the total power is the same or less
than 50 % of the power at the 100 % light power setting
• The ECG must be capable of reducing the light power to 10 % or
less of the maximum power
85

9.6 The DALI standard (IEC 62386) at a glance
• Each controller must fulfill Part 102.
• A controller can belong to a number of different device types (Part
100, 200, 300).
• Specific commands and features are defined and described in
