1 Safety

1.1 Definition of Symbols


Stop (Stop Danger). This symbol warns of serious danger of severe injury to

persons. It must be strictly observed.

Attention (Warning). This symbol indicates information the non-observance of

which can lead to extensive damage to property. The safety warning must be

strictly observed.

Information. This symbol indicates key information on use. Non-observance can

lead to failure.

1.2 Safety Advice

The ELC must be installed and connected in compliance with existing

regulations and practices. This is e.g. EN 60204-1 in Europe.

Repairs on the ELC may only be carried out by the manufacturer.

The installation and starting up may only be carried out by skilled electricians.

Do not open the ELC before it is disconnected from the mains. BEWARE OF

RESIDUAL VOLTAGE! The unit may still be live up to three minutes after it has

been switched off.

ELC PE22_PE32-V2.2-09.11-GB Subject to technical alterations


1 Safety page 2

The ELC causes a leakage current greater than 3.5 mA!

Safeguarding by means of leakage current protection type A and type AC

according to IEC 60755 is not permitted!

The ELC operates in principle as a frequency converter and is equipped with a

mains filter whose leakage current could activate fuse protection.

Contact to the grounding connector must always be ensured.

Additional measures must be taken to ensure that there is no danger when

touching the appliance. This could be by means of a universal leakage current

protection type B, taking into consideration the increased response threshold, or

by means of an independent equipotential connection.

1.3 Correct operation

The ELC is an electrical unit intended to be installed in the switch cabinets of

industrial high-voltage power installations. It is conceived as an electronic ballast

for the operation of lamps intended for this purpose.

Any other use is deemed as misuse. The manufacturer will not assume liability

for damage resulting from misuse.

A pre-requisite for authorised operation of the ELC is the observance of both the

operating and maintenance instructions and the safety advice.

1.4 Extended use

Extended use beyond the operating specifications as stated is not permitted.

The manufacturer will not assume liability if the equipment is used in any other

way. The operator acts at his own risk.

Any operation beyond the scope of the authorised operation is considered to be

misuse.

2 Description of functions page 3

2 Description of functions

The ELC is an electronic power supply unit for the operation of gas discharge lamps with

electrical properties as described in chapter 6.

In contrast to conventional ballasts (inductive lamp ballast or transformer or transformer with

transductor), the lamp with an electronic ballast is operated with high frequency (approx.

100 kHz). The lamp does not flicker and dimming is infinitely adjustable to a range between

20 % and 100 % of the electric power or to between 15 % and 100 % of the UV radiation

respectively.

Dimming

The possibility of dimming the lamp has two advantages. Firstly the lamp can be switched to

minimum load (standby operation) during longer idle times and energy can thus be saved.

Secondly the optimum lamp power can be determined and adjusted as appropriate.

Power control

The ELC offers a high level of lamp power constancy due to its integrated power control.

Variations in operating voltage of ± 10 % do not affect lamp power.

Ignition device

When the lamp is switched on the ELC initiates trigger pulses to fire the lamp; a separate

ignition device is not required.

Other performance characteristics

• High level of electrical efficiency.

• Configuration, control and monitoring of the ELC is carried out via PROFIBUS-interface.

• The ELC monitors the lamp cables for earth fault.

• The lamp output potential is separated from that of the supply voltage.

• The ELC is both short-circuit proof and safe in open circuit operation at the lamp output.

3 Installation

3.1 Mounting of casing

The ELC must be installed in a control cabinet with at least IP 54 protection (see

EN 60529). Operation without a control cabinet or in a control cabinet with a

lower degree of protection is not permitted.

It is only permitted to install the appliance in the positions described in 3.1.1 or

3.1.2. When installed vertically, as described in Fig. 1, the control connections

must be positioned at the bottom and supply connections at the top. Installation

must allow for the minimum spacing.

The ELC should not be mounted in the immediate proximity of sensitive

electronic equipment. An appropriate distance must be maintained to scatter

field transformers or other inductors.

The flow of cool air for the ELC must be safeguarded. The ambient temperature

must not exceed the values prescribed in chapter 6.

Ventilation must be provided for the switch cabinet.

The amount of air necessary is determined by the size and positioning of the

switch cabinet, the total electrical losses and the external temperature. Please

consult your switch cabinet manufacturer. For the recommended throughput of

air please see the technical data in chapter 6.

Impure cooling air could affect the functionality of the ELC. This can be avoided

by installing a fine air filter.

3.4 Comments on the safety functions of the ELC

Fig. 10: Safety circuits of the ELC

3.4.1 Safety relay

ELC PE22_PE32-V2.2-09.11-GB Subject to technical alterations

ELC with PROFIBUS feature

two safety circuits, as shown

schematically in Fig. 10:

1. Safety relay K1 with

feedback via the normally

closed contact (paragraph

3.4.1)

2. Monitoring of the

initialisation signal

(paragraph 3.4.2)

To set the ELC ready for operation, the safety relay K1 has to be activated by applying +24V

to pin X1.3 and GND on pin X2.3.

As long as the safety relay is not activated, lamp operation is not possible! There are two

feedback paths:

• a normally closed relay contact. It may be tapped on pins X2.1 and X2.2.

• the [Warning Register] of the PROFIBUS-input-data (see below and paragraph 5.2:

Bit 4 {Safety Relay Open})

If the safety relay is deactivated during lamp operation, lamp operation will be shut down.

After reactivating the safety relay, the lamp has to be restarted.


3 Installation page 15

3.4.2 Initialisation signal

Furthermore lamp operation will not be allowed unless +24V are applied to pin X1.1 and

GND on pin X1.2. This is an additional monitoring function for the safe operation of the

installation. The status of pin X1.1 is visualized in the [Warning Register] of the PROFIBUSinput-data

(see below and paragraph 5.2: Bit 7 {Init Signal Ok}).

If the initialisation signal is deactivated during lamp operation, lamp operation will be shut

down. After re-applying the initialisation signal, the lamp has to be restarted.

3.5 Configuration

Communication between ELC and installation control is carried out via PROFIBUS DPV0.

The ELC represents a non-modular DPV0-Slave, the installation control functions as the

Master.

For configuration, control and monitoring of the ELC 16 input registers (Master receiving data

from ELC) were implemented, as well as 6 output registers (Master sending data to ELC).

For registers overlapping more than one byte, the byte order was determined according to

”Big-Endian“.

The preset baud rate is recognized automatically by the ELC. Software supports all baud

rates from 9.6kBit to12MBit; tested values can be taken from the technical data in chapter 6

(limitations may be caused by the connector).

The necessary adjustments during the installing of the ELC will be explained in this

paragraph, the adjustments for lamp operation will follow in chapter 4.

• To ignite the lamp set the {Start Lamp}-Bit in register [Lamp Control] to 1.

• {n/a}: not available. These bits are reserved for future applications.


4 Operation of ELC page 22




Power must be applied to the ELC for at least 2 seconds before attempting to

fire the lamp.

In case of an error the ELC will not try to ignite the lamp. After eliminating the

error the [Error Register] has to be cleared additionally (see paragraph 5.3).

As long as the safety circuits are not activated the ELC will not try to ignite the

lamp (see paragraph 5.2).

During warm-up the lamp power stays at a very low level over a longer period of time and

after approximately 60 seconds rapidly increases to its nominal power. The lamp is operated

with increased current until the nominal power is reached. The actual condition of the lamp

may be read out from register [Lamp Status] of the PROFIBUS-input-data:

4.5 Dimming operation

After having reached nominal operation the desired lamp power can be infinitely adjusted.

• Enter the desired power in Watts in register [Power Set Value].


A set value of less than 20% of the ELC-nominal-power will automatically be

increased by the ELC to 20% of the ELC nominal- power.

4.6 Standby operation

During longer idle times the ELC can be switched to standby operation. The lamp is operated

at minimum power but can be brought up to nominal power within a few seconds.

• Standby operation corresponds to 20% of the ELC nominal power. This can be attained

by setting the register [Power Set Value] at a value equal to or lower than 20% of ELC

nominal power.

The warm-up time from standby operation to nominal operation depends on the lamp's

ambient conditions. If cooling is too intensive during dimming operation, the acceleration time

is prolonged.

4.7 Switching off the lamp

• The lamp is switched off by setting the {Start Lamp}-bit to 0 in register [Lamp Control].


In order to avoid heat accumulation in the ELC the power supply should be left

on for a few minutes. Before restarting, the lamp must be sufficiently cooled

down as it cannot be fired otherwise.

5.1 Earth fault control

Supplementary to the safety functions of paragraph 3.4 which prevent danger to the

operator, the earth fault control of the ELC lamp circuit represents another monitoring

function.

ELC PE22_PE32-V2.2-09.11-GB Subject to technical alterations

An earth fault occurs when the isolation resistance

R_error (see Fig. 14) drops below approx. 200 kOhm.

The ELC will shut down the lamp automatically in

case of an earth fault.

In order for the earth fault control to function properly

it is essential that the ELC is connected as

prescribed, particularly the earth connectors.

An earth fault is reported by the {Earth Leakage

Fault}-bit in the [Error Register] (in normal

operation status the bit value is 0).

Earth fault monitoring is also active if the lamp is not

running. However the error message will only be

effectuated when trying to start the lamp.

In order to avoid an unwanted reaction of the earth fault control during faultless

operation, the isolation resistance of the lamp cables and all lamp connectors

must be greater than 10 MΩ.

5.2 Warning messages

The bits in the [Warning Register] are divided into two groups:

• Group1-Nibble: the bits 0-3 represent critical operating conditions of the lamp. However

they won’t shut down the lamp.

• Group2-Nibble: If a bit in the Group2-nibble (bits 4-7) is set, the lamp cannot be started

or will be shut down during operation.

The bits of the [Warning Register] will automatically be reset as soon as the triggering status

has been resolved.

Bit 0: The {Lamp Voltage Low}-bit is set if the burning voltage of the lamp falls

below its minimum (set by the manufacturer). This bit will be reset if the lamp

voltage exceeds the minimum.

Bit 1: The {Run Up Long}-bit is set if the warm up of the lamp takes longer than

expected. Reset occurs as soon as the {Start Lamp}-bit in register [Lamp

Control] is set to 0 (the lamp being thus actively shut down by the operator

via the PROFIBUS output data).

Bit 4: The {Safety Relay Open} bit is set if the safety relay is not closed (e.g. on

emergency shutdown). There are two different cases:

• If in register [Lamp Control] {Start Lamp} bit is 0, the {Safety Relay

Open} bit is automatically reset as soon as the safety relay is closed.

• During lamp operation ({Start Lamp}=1 in [Lamp Control]) the {Safety

Relay Open} bit remains set and the lamp will be shut down by the ELC.

In this case {Safety Relay Open} will only be reset if {Start Lamp} in

[Lamp Control] is reset and the safety relay has been closed.

Bit 5: If the ELC cannot ignite the lamp the {Lamp Ignition Failed} bit will be set

and remains in this status as long as {Start Lamp}=1 in [Lamp Control]. The

{Lamp Ignition Failed} bit is reset as soon as {Start Lamp} in [Lamp

Control] is reset.

Bit 7: The {Init Signal Ok} bit reflects the status of the Init-Pin X1.1 of the

initialisation signal (see paragraph 3.4.2).

• {Init Signal Ok}=1 means 24 V on X1.1, the lamp may be ignited and

operated normally.

• {Init Signal Ok}=0 means 0 V on X1.1, the lamp cannot be operated.

To render the ELC operational again in case {Init Signal Ok}=0 the

initialisation signal on X1.1 has to be 24V and the start signal {Start Lamp}

has to be reset.

Bit 2, Bit 3 und Bit 6: {n/a} bits (not available) are reserved for future applications.

5.3.3 Resetting the error register

Each error has to be acknowledged by setting the {Clear Error} bit in register [Lamp

Control] to “1”. First of all set the {Start Lamp} bit in register [Lamp Control] to 0. Then

only the transgression of the {Clear Error} bit from “0” to “1” can reset the [Error Register].

After the PROFIBUS has transmitted the [Lamp Control] Register (check e.g. via the [Error

Register]: if error eliminated all error bits are „0“ again) and after an ELC internal

synchronisation time of additional 15 ms, the {Clear Error}-bit has to be reset to „0“.
