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.
