Dimming actuator, 4-gang
Switch on the mains voltage of the outputs again. Switch the affected output off and on
again.
When a short-circuit occurs the affected output switches off. Automatic restart when short-
circuit is eliminated within 100 ms (inductive load) or 7 seconds (capacitive or ohmic
load). After that lasting switch-off.
When a short-circuit occurs during the calibration process, the load calibrates itself again
after the short-circuit is eliminated.
Cause 4: load failure.
Check load, replace light bulb. For inductive transformers, check primary fuse and replace
if necessary.
Manual control with button field not possible
Cause 1: Manual control has not been programmed.
Program manual control.
Cause 2: Manual control via bus disabled.
Enable manual control.
None of the outputs can be operated.
Cause 1: All of the outputs are disabled-
Cancel disabling.
Cause 2: Manual mode active.
Deactivate manual mode (switch off continuous manual mode).
Cause 3: Application software missing or faulty.
Check programming and correct.
All outputs off and not possible to switch on
Cause 1: bus voltage failure.
Check bus voltage.
Luminaires flicker or buzz, proper dimming not possible, device buzzes
Cause: wrong dimming principle set
Installation or commissioning error. Disconnect device and luminaire, switch off circuit
breaker.
Check installation and correct.
If the wrong dimming principle has been preselected: Set correct dimming principle.
If dimming actuator calibrates itself incorrectly, e.g. with highly inductive mains or long
load cables: preselect correct dimming principle with commissioning.
LED lamp is dimly lit when dimmer is switched off
Cause: LED lamp is not optimally suited for this dimmer.
Use a compensation module, see accessories.
Use another type of LED lamp or an LED lamp of another manufacturer.
