Dimming actuator 1-gang 200 W with binary input, 3-gang
With the "Universal" setting: Define the dimming principle manually.
Connected HV-LED lamps or compact fluorescent lamps in the lowest dimming position are too
bright; dimming range is too small
Cause 1: The set minimum brightness is too high.
Reduce minimum brightness.
Cause 2: HV-LED trailing edge phase control dimming principle does not optimally match the
connected lamps.
Check operation in the "HV-LED leading edge phase control" setting, reduce connected
load as well if necessary.
Exchange lamps for another type.
Output has switched off.
Cause 1: overheating protection has tripped.
Disconnect output from mains, switch off associated circuit breakers.
HV-LED trailing edge phase control: Reduce the connected load. Exchange lamps for an-
other type.
HV-LED leading edge phase control: Reduce the connected load. Check the operation in
the "HV-LED trailing edge phase control" setting. Exchange lamps for another type.
Let device cool down for at least 15 minutes. Check installation situation, ensure cooling,
e.g. provide distance from surrounding devices.
Cause 2: Surge protection has triggered.
HV-LED trailing edge phase control: Check the operation in the "HV-LED leading edge
phase control" setting, reduce the connected load as well if necessary.
Exchange lamps for another type.
The response of the surge protection can be signalled by sending a short-circuit telegram
or can be determined by polling the "short-circuit" communication object.
Cause 3: short-circuit in output circuit
Disconnect the output from the mains supply.
Eliminate short-circuit.
Switch on mains voltage 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.
Output cannot be operated.
Cause 1: Output is disabled.
Cancel disabling.
Cause 2: Application software missing or faulty.
Check programming and correct.
Output 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
