Operating instructions
1 Safety instructions
Electrical equipment may only be installed and fitted by electrically skilled persons.
Failure to observe the instructions may cause damage to the device and result in fire and
other hazards.
Danger of electric shock. Always disconnect before carrying out work on the devise or
load. At the same time, take into account all circuit breakers that supply dangerous
voltage to the device or load.
Danger of electric shock. Device is not suitable for disconnection from supply voltage.
The load is not electrically isolated from the mains even when the device is switched off.
Do not connect any electronic lamps, e.g. switchable or dimmable compact fluorescent
lamps or LED lamps. Device can be damaged.
Fire hazard. For operation with inductive transformers, each transformer must be fused
on the primary side in accordance with the manufacturer's instructions. Only safety
transformers according to EN 61558-2-6 may be used.
These instructions are an integral part of the product, and must remain with the end
customer.

i Brief flickering upon load detection of ohmic loads. No operation is possible during load
detection.
Behaviour on failure and return of the mains power supply
If only the main power supply fails, then the status of the load output remain intact at first. The
dimmer station initialises when the mains power supply returns. All load outputs are switched off
after initialisation.
i During initialisation the dimmer station cannot be operated. The green and red Status
LEDs (4) of all the load outputs A1...A4 illuminate. Initialisation is complete as soon as all
the Status LEDs are off.
Behaviour on failure and return of the mains voltage on one or more load outputs
Should the mains voltage fail, the affected load outputs will switch off. When the mains voltage
returns, the affected load outputs will recalibrate themselves. During the calibration operation,
the green and red Status LEDs (4) illuminate and the load outputs cannot be operated. The load
outputs are switched off after calibration.
Function of hotel card switch
In combination with a hotel card switch, the light is switched on at switch-on brightness when
the hotel card is inserted. When the hotel card is removed, any switched-on lights remain
switched on for 1 minute and the dimmer station can be operated. When this time has elapsed,
the light is darkened within 3 minutes to minimum brightness and is then switched off. The
dimmer station can no longer be operated.
i Only load outputs to whom the central function has been assigned are switched on, whilst
all the load outputs are switched off.

Connecting loads to load outputs switched in parallel
Figure 4: Connection example of load outputs switched in parallel
CAUTION!
Risk of destruction of load outputs switched in parallel if the device is set
incorrectly.
Dimmer and loads may be destroyed.
Specify the Master and the Slave before connecting the loads to the load
outputs.
CAUTION!
400 V are shorted when outputs switched in parallel are connected to different
outer conductors.
The device will be destroyed.
Always connect outputs switched in parallel to the same outer conductor.
CAUTION!
When connecting power extensions to load outputs switched in parallel, there
is no guarantee that the dimmer sets the dimming principle suitable for the
load.
Dimmer, power extension and load may be destroyed.
Do not connect any power extensions to load outputs switched in parallel.
Only subject load outputs switched in parallel to up to 80%.
The minimum load of parallel switching of load outputs is 150 W.

other control sections such as push-buttons (24 V) (18), push-button modules 24 V (18) and
unlit installation buttons (20), to the dimmer station.

Operation of two dimmer stations with a sensor module or push-button module
Sensor modules or push-button modules can operate two dimmer stations together. This
requires connection of both dimmer stations in parallel. To do this, the sensor modules must
have at least release version R2. The device address of a dimmer station must be changed
(see "Setting the device address")
Figure 8: Connection example for one sensor module or push-button module to two dimmer
stations
o Connect the sensor module or push-button module to two dimmer stations according to the
connection example (figure 8).
i Connect the power supply of the dimmer stations to the same outer conductors.
i Even dimmer stations switched in parallel may only have four sensor modules or push-
button modules connected to them.
Operation of multiple dimmer stations with a push-button 24 V or push-button module 24
V
In operation with push-button 24 V or push-button module 24 V, they can be connected to up to
four dimmer stations. To do this, the negative poles of the individual dimmer stations have to be
connected to each other. It is possible, for example to switch load outputs of several dimmer

6.2 Troubleshooting
Load output switches the load off briefly and then on again.
Cause: short-circuit protection has tripped but now there is no longer a fault.
Load output switches the load off and cannot be switched on again.
Cause 1: short-circuit protection has tripped, the red and green Status LEDs (4) of the
appropriate load output flash.
Eliminate short-circuit.
Switch on load output again.
i Short-circuit protection is not based on a conventional fuse, no metallic separation of the
operational current.
Cause 2: overtemperature protection has tripped, the red Status LED (4) of the appropriate load
output flashes.
Load output is defective.
Load output switches the load off and can only be switched on again after a certain time.
Cause: overtemperature protection has tripped due to an overload or an excessively high
ambient temperature, the red Status LED (4) of the appropriate load output flashes.
