1 Multifunction Control Unit MDK-ES-10 

1.1 Introduction 

The MDK-ES-10 is a multifunction control unit employing forward phase control technique. It can be controlled in 

various modes and can also regulate different loads: 

•= control via potentiometer 

•= control by a single key 

•= control by several keys 

•= control with switch-dim actuator 

•= 

•= 

regulating fluorescent lamps via dimmable electronic ballast 

regulating additional standard control units 

The MDK has both a an analogue output (0...10V) and a switched output (230V). Both outputs have an 

integrated switch-on/off function, so that installation of the usual contactor is superfluous. 

The MDK can be connected to several control points, and several MDKs may be paralleled to a central control 

panel. 

Moreover the MDK can control the load according to daylight or movement, or switch the load on and off 

centrally. 

1.2 Intended use 

A varitens multifunction control unit is intended solely for controlling light sources. It is suited for use in indoor 

switch panels, though the ambient conditions set out in Section 11 (Technical Data) must be assured for certain. 

The control unit may be put into operation and placed under voltage only after proper connection according to 

Section 3 to 5 "Control", "Load Circuit" and "Standard Diagrams" (Standard Applications). 

Note: 

The manufacturer (or supplier of the MDK-AN06 as the case may be) declines all liability for any 

damage or injury to persons caused by improper use or failure to observe these instructions. 

1.3 Basic specifications 

The MDK is supplied complete as a snap-on unit for cap rail mounting, together with these operating instructions. 

All functions described in the instructions are implemented at all times. 

2 Safety rules 

2.1 Responsibilities 

Installation, commissioning or maintenance of the MDK-ES-10 may be performed only if the following safety rules 

are observed as well as the safety-relevant instructions in the individual sections. In particular the person 

installing the control unit is responsible for the security of persons and for any material damage, also for 

providing the operator with the necessary information. He is furthermore responsible for satisfying the general 

work safety regulations in force and the safety rules for working on medium-voltage electrical equipment. 


CH-8957 Spreitenbach 

11522e V3


2.2 Safety symbols 

The following symbols draw attention to the various danger levels in the individual sections: 

Information, instructions or prohibitions to prevent serious damage or injury to persons. 

Special information, instructions or prohibitions for preventing lesser damage. 

Note: 

Special information for obtaining the best use from the equipment. 

2.3 Residual dangers 

If the MDK-ES-10 is used as it should be, all relevant standards and regulations aimed at preventing injury to 

persons and damage will be fulfilled. Nevertheless residual dangers from live connections cannot be ruled out 

entirely. The principal parts with potential residual dangers are shown in Fig. 2-1 below: 

Fig. 2 - 1 

Potential residual danger by touching connections under medium voltage (230 Vac) 

2.4 Special rules to be observed 

The MDK-ES-10 multifunction control unit may be installed and used only if it is in perfect 

condition and the operating instructions are complied with. 

The electrical connections (supply and control unit output etc.) may be connected and 

disconnected only when not under voltage (see also section 2.3: Residual Dangers). 

Working on live connections may lead to severe injury due to electric shock. 

The output LS is not isolated when the control unit is switched off. A separate automatic cutout 

must be fitted in the supply lead. 

11522e V3 




3 Control 

The MDK differentiates between 8 operating modes, which are adjusted on it from outside with 3 DIP switches. 

The 8 modes differ in the way the MDK is controlled: 

•= analogue control with ON/OFF key 

•= analogue control without ON/OFF key 

•= single-key control (ETS)) 

•= daylight-dependent control (TLR) 

•= multikey control (MTS) with 4 presets with program enable 

•= multikey control (MTS) with 4 presets without program control 

•= multikey control (MTS) with 2 presets with program control 

•= ultikey control (MTS) with 2 presets without program co 

With a further DIP switch the control unit may be switched over into a service mode, and with another 2 DIP 

switches the kind of lamp may be selected.

3.1 Analogue control with ON/OFF key 

With a standard 10 k potentiometer the load is regulated from the adjustable minimum light value to the similarly 

adjustable maximum. Instead of the potentiometer a 0-10V control voltage or sink current source (e.g. EIB 

switching dimming actuator) may be used. With sink current control a jumper must be placed between IN:0-10V 

and 12V-10k . Using an ON/OFF key with back signalling (LED), the MDK is switched on and off. When the 

control unit is switched off the switched output is likewise inactive. 

In this operating mode the inputs for movement detector (Section 3.9) and central ON/OFF (Section 3.10) are 

usable.

•= Analogous with ON/OFF 

Fig. 3 - 1 Potentiometer and ON/OFF key with back signalling, e.g. PDP-H-ETE, Art. No. 313.10.014 

3.2 Analogue control without ON/OFF key 

A potentiometer, an external control voltage 0-10V or a sink current source (e.g. EIB switching dimming actuator) 

is to be connected. In this mode the control unit is switched on and off via the control voltage. A voltage below 

0.6V switches the control unit off, a voltage above 0.6V switches it on again. When the control unit is switched off 

the switched output for preheating is also inactive. 

In this operating mode the inputs for movement detectors (Section 3.9) and central ON/OFF (Section 3.10) are 

usable.

•= 

Analogous without ON/OFF 

Note: The connection diagram is as Fig, 3-1 without ON/OFF key. 

11522e V3 




3.3 Single-key control (ETS) 

In this mode only the ON/OFF key with back signalling is active. A short actuating pulse (50...300 ms) switches 

the control unit on or off. A long pulse (exceeding 300 ms) dims. The sense of action is reversed by releasing the 

key and then pressing it again longer than 300 ms. The control unit runs from one limit to the other. When it is at 

minimum (service parameter "minimum light") the heat conductor remains switched on. 

The heat conductor and the phase angle are switched off by the ON/OFF function. 

When the control unit is switched off and the ON/OFF key is pressed and not released, the control unit runs from 

0% to 100% brightness after 300 ms (dimming function). 

If the light is dimmed to 0% brightness, depending on the control the output LS switches off after 1s (see Section 

4). 

When the control unit is switched on by briefly pressing the key, the value active before switching-off is assumed. 

If this was less than 5% of the maximum, the switch-on light value is assumed. (The switch-on value is stored 

with the ON/OFF key in the MTS mode).

3.4 Daylight-dependent control (TLR) 

By connecting a mixed light sensor (LFM) with an ON/OFF key and "lighter" and "darker" keys, daylightdependent 

control can be obtained. For the ON/OFF key a back signalling LED may be controlled. With the 

lighter and darker keys the setpoint can be altered. With the ON/OFF key the adjusted light setpoint can be 

stored (press till the back signal of the ON/OFF key flashes). When the control unit is switched on, the stored 

value is regulated (basic value 5V). If the daylight changes, the MDK regulates the artificial light till the adjusted 

setpoint is reached. If artificial light is no longer necessary, it is switched off. When daylight fades (e.g. in the 

evening) the artificial light is switched on again.

In this mode the following keys may be connected: 

•= ON/OFF with back signalling 

•= lighter 

•= darker 

•= preset 1..4 with back signalling 

The control unit is switched on with the ON/OFF key. The switch-on light value is assumed. By pressing one of 

the preset keys (50 ms ... 3 s) the control unit can be switched on also. A preselected light value is then 

assumed. With the "lighter"/"darker" keys the value may be altered and stored as new setpoint by prolonged 

pressure (over 3 s) on the corresponding preset key. By prolonged pressure (over 3 s) on the ON/OFF key the 

switch-on light value can be stored. Light values cannot be stored while the control unit is switched off.

3.9 Movement-dependent control 

A movement detector connected to the MDK with potential-free contacts (or open collector output) switches on 

the lighting when the room is entered and switches it off again when it is left. This operating mode may be 

combined with others, though with multikey control there may be only 2 presets still available. 

Note: 

The movement detector is connected at terminal T4, consequently this operating mode cannot be 

combined with multikey control with 4 presets and program enable or multikey control with 4 presets 

without program enable.

11522e V3 




3.10 Central switch-on/off 

By connecting an ON and an OFF key, one or more MDKs may be switched on and off centrally from a single 

point. 

Note: 

The central ON and OFF keys are connected at the terminals R3 and R4. Consequently this 

operating mode cannot be combined with multikey control with 4 presets and program enable or 

multikey control with 4 presets without program enable.

3.11 Switch-on or overdrive with analogue signal with key control 

By applying a voltage at the analogue input (IN 0-10V) the control unit is switched on or overdriven. In this way 

an emergency circuit may be obtained. There are two possibilities for this: 

•= With a potential-free contact the 10V output of the control unit is switched onto the analogue input.

•= 

An external voltage (below 10V) may be switched onto the analogue input.

11522e V3 




4 Load circuit 

With the multifunction control unit, dimmable electronic ballasts (EVGs) or dimmers are operated. Besides the 

analog output (0...10V) the unit has a solid-state relay with which loads up to a current of 10A are switched on 

and off. 

With the DIP switches 1 and 2 the load to be controlled can be selected. When an EVG is selected, the switched 

output has a preheat time of 0.45/1.5s compared with the analogue output (see Section 7 for preheat time of 

EVG). With dimmers the preheat time is 50ms. 

If the light is dimmed to 0% brightness with key control in the 2nd switch setting (EVG is cut out at min. light), the 

output LS cuts out as soon as the minimum light has been controlled during 1 s. With the other two switch 

settings the output LS remains switched on.

4.1 Fluorescent lamps (FL) with dimmable electronic ballasts (EVGs) 

When using dimmable electronic ballasts the switched voltage of the MDK is taken as supply voltage and the 

analogue output as control signal. The analogue output may be loaded up to +6,-100mA (equivalent to 650 

setronic(R) EVGs). The switched output LS can be loaded with 10A. If a heavier current is needed, a contactor 

may be controlled with this output (see Section 4.3). 

If the light is dimmed to 0% brightness in the 2nd switch setting (EVG cuts out at minimum light) the output LS 

cuts out as soon as the minimum light has been controlled during 1s. In the other switch setting the output LS 

remains switched on.

4.2 Standard dimmers 

When using dimmers (phase angle or phase interval) the switched voltage of the MDK is utilized as supply 

voltage and the analogue output as control signal. The analogue output may be loaded up to +6,-100mA. The 

switched output LS can be loaded with 10A. If a heavier current is needed, a contactor may be controlled with 

this output (se Section 4.3).

4.3 Three-phase load with EVGs 

With dimmable electronic ballasts (EVGs) a three-phase distribution of the load is possible too. The output can 

be loaded with up to +6,-100mA. These additional EVGs may be isolated from the network with a load relay 

controlled by the switched output of the MDK.

5 Standard diagrams (standard applications) 

5.1 Several MDKs, paralleled control points (external supply) 

Any number of MDKs operating in parallel for different lighting circuits can be controlled from a central panel and 

with distributed secondary operating points. Together with the preset keys it is possible to store 4 genuine 

lighting moods. 

Each circuit has separate "lighter" and "darker" keys, allowing a different light value to be programmed for each 

circuit. All circuits together have a common ON/OFF key, common "lighter" and "darker" keys and up to 4 preset 

keys. The common "lighter" and "darker" keys must be connected through diodes. 

As digital control unit the MDK can be actuated from any number of parallel control points. The integrated power 

supply allows acknowledgement diodes up to 40 mA to be paralleled. If more acknowledgement diodes are 

needed, an external voltage source must be connected. The MDK can switch acknowledgement diodes up to a 

maximum current of 700 mA.

If the control units happen to be asynchronous, they can be synchronized again by pressing a preset 

key.

5.2 Daylight-dependent regulation with 2 circuits 

Daylight-dependent regulation of 2 lighting circuits is to be provided in a room with different light levels in 2 

zones. The lighting on the window side and on the opposite side for instance is to be controlled by separate 

circuits. To adjust the setpoint of circuit 1, circuit 2 is switched off with ON/OFF key 2. The light value for circuit 1 

is selected with the "lighter" and "darker" keys and stored with ON/OFF key 1. Circuit 2 is adjusted similarly.

5.3 Room interconnection in MTS mode 

A room is separated by a removable partition. In both parts the lighting is regulated with an MDK. When the 

partition is removed it must be possible to adjust the entire room lighting from either control point. By pressing 

the "COMMON" key, the keys of the control consoles are interconnected, enabling genuine light moods to be 

obtained.

Note: 

If the control units happen to be asynchronous, they can be synchronized again by pressing a preset 

key. 

11522e V3 




6 Switch-on/off ramps 

When switching on and off the control unit is always run up and down a ramp of 500 ms. As a result, any 

transformer connected does not get saturated when switching on: there is no current peak. 

Fig. 6 - 1 

Switch-on and switch-off ramps 

7 Switched output 

The switched output LS is activated before the switch-on ramp of the analogue output begins. This enables the 

electrodes of fluorescent lamps to warm up to the requisite temperature, which makes for longer lamp life. 

Depending on the load (EVG or dimmer) being used, different values are taken. The preheat time used with 

EVGs can be fixed in the service mode between 0.45 s and 1.5 s (see Section 9.6 "Preheat Time").

8 LED signalling on control unit 

There are three LEDs on the control unit: 

•= red LED 230 V supply (power) 

•= yellow LED control unit working (run) 

•= green LED status display (status) 

The red LED indicates the presence of the supply voltage. 

hen the yellow LED flashes at 1-second intervals the control unit is working properly. 

The green LED lights while the control unit is switched on and is dark when it is switched off. The green LED also 

signals overheating inside the MDK. This is tripped around 70°C (green LED flashes). The control unit then 

automatically reduces the analogue output to 50%. If the temperature continues to rise, the switched output LS is 

cut out completely.

When returning to the operating mode (DIP switch 3 to OFF) the changed parameters are taken over. 

9.1 Setting time analogue 

"Setting time analogue" denotes the time taken by the control unit in the analogue operating mode to effect a 

change from one setpoint to another. This way continuous fading is obtained despite abrupt setpoint change. The 

value can be altered in 0.5 s steps between 0.5 s and 20 s. 

If the control unit is in the analogue mode, after changing DIP switch 3 the "setting time analogue" parameter is 

selected. The light now runs endlessly up and down between minimum and maximum. 

t = Setting time analogue 

Fig. 9-1 Analogue output with parameter adjustment "setting time analogue" 

The back signalling of the ON/OFF key lights. By briefly pressing the ON/OFF key (50ms...300ms) the time is 

lengthened by 0.5 seconds. Prolonged pressing of the ON/OFF key (over 300 ms) shortens the time by 0.5 

seconds. 

Note: 

If a variant with only one potentiometer (without ON/OFF key) is selected, an ON/OFF key must be 

connected temporarily to the corresponding terminals to adjust the "setting time analogue. 

9.2 Setting time 

The setting time is the time needed by the control unit in a digital operating mode (ETS or MTS) to change the 

setpoint from 0% to 100% with the "lighter" key. The value may be altered in 0.5 s steps between 0.5 s and 20 s. 

If the control unit is in the ETS or MTS mode, after changing DIP switch 3 the setting time parameter is selected 

automatically. The light now runs up and down endlessly between minimum and maximum.

time is lengthened by 0.5 seconds. By prolonged pressing of the same key (over 300 ms) the time is 

shortened by 0.5 seconds. 

With the preset 1 key the setting time is selected. The back signal of preset 1 key lights. By operating 

the "lighter" and "darker" keys the parameter may be increased or reduced in 0.5s steps. 

9.3 Fading time 

The fading time is the time taken by the control unit in the MTS mode to change from one preset value to 

another. It may be altered in 0.5 s increments between 0.5 and 20 seconds 

If the control unit is in the MTS mode, after changing DIP switch 3 the setting time parameter is selected 

automatically. The light now runs up and down endlessly between minimum and maximum. 

t = Fading time

9.4 Minimum light value 

The minimum light value is the minimum control unit output that can be modulated. It can be varied between 0% 

and 50%. 

TLR: 

After changing the DIP switch 3 the minimum light value parameter is selected automatically. It can be 

raised or lowered with the "lighter" and "darker" keys. (Pressing the ON/OFF key changes from the 

maximum light value to the minimum light value parameter) 

If the minimum light value is greater than 0, the control unit does not cut out although there is 

sufficient light. 

MTS: 

With the preset 3 key the minimum light value is selected. The back signal lights on the preset 3 key. 

After selecting the parameter the adjusted value is modulated. It can be increased or reduced with 

the "lighter" or "darker" key. 

9.5 Maximum light value 

The maximum light value is the maximum control unit output that can be modulated. It may be altered between 

50% and 100%. 

TLR: 

After changing DIP switch 3 the maximum light value parameter is selected automatically. By pressing 

the ON/OFF key the maximum light value parameter is selected. It may be increased or reduced with 


MTS: 

With the preset 4 key the maximum light value is selected. The back signal of the preset 4 key lights. 

After selecting the parameter the adjusted value is modulated. It may be increased or reduced with 


9.6 Preheat time 

The "preheat time" is the time by which the switched output of fluorescent lamps is switched on before the ramp 

of the dimmed output. It may be changed between 0.45 s and 1.5 s. 

MTS: 

By prolonged simultaneous pressing of preset keys 1 and 2 (more than 3s) the preheat time is 

changed between 0.45s and 1.5s. The change is indicated by the ON/OFF key flashing. 

9.7 General reset 

If the control unit is in its service mode, a general reset can be obtained by pressing the ON/OFF key at least 10 

seconds. After releasing it the acknowledgement flashes, indicating that the general reset has been carried out. 

Pressing any key returns the control unit to the normal service mode; parameters may be altered again. The 

basic adjustments are: 

•= setting time in MTS, ETS 8s 

•= fading time 5s 

•= minimum light value 0% 

•= maximum light value 100% 

•= preheat time 5s 

•= switch-on light maximum light value 

•= setting time analogue 500ms 

•= daylight control regulating value 5V 

•= preset 1 33% 

•= preset 2 50% 

•= preset 3 67% 

•= preset 4 100%

10 Installation and wiring 

To install the multifunction control unit the supply voltage must be cut off on the input side. 

10.1 Installing the MDK 

The MDK is mounted on a cap rail by placing in onto the rail from below and then engaging it onto the front with 

a light pressure. 

 

 

 

Fig. 10 - 1 Dimensions of the MDK 

11522e V3 




10.2 Placing in electric's cubicle 

A number of MDKs may be accommodated in an electric's cubicle. A distance of 8 mm must be assured between 

the control units themselves and between the associated cable channels. A distance of 25 mm must be 

maintained between groups. The control units may also be installed staggered against a common cable channel. 

Each individual MDK generates a 15W power loss under nominal load. When installing several control units in 

the cubicle therefore, it must be ensured that the temperatures of the individual controllers do not exceed 70øC. 

With unventilated cubicles the power loss of all equipment installed must not exceed 270 W/mm3. Accordingly in 

a cubicle measuring 1800x800x600 mm about 15 MDKs could be installed. 

If ventilation is provided in addition, or the control units do not operate under nominal load simultaneously, the 

number of control units may be increased.

13 Maintenance and disposal 

Maintenance 

There are no parts needing maintenance inside the MDK. It must be replaced if it is defective. Excessive dust 

should be cleaned from the outside of the MDK from time to time. (The power electronics inside it set up heat, 

which can be dissipated only if there is adequate air circulation. Excessive dust will obstruct the air circulation). 

Disposal 

If the MDK has to be disposed of it must be treated as electrical scrap. There are no parts in it demanding 

treatment as special waste.
