7 Troubleshooting
Connected LED lamps or compact fluorescent lamps switch off in the lowest dimming position
or flicker
The set minimum brightness is too low.
Increase minimum brightness.
Connected LED lamps or compact fluorescent lamps flicker
Cause 1: Lamps are not dimmable.
Check manufacturer's instructions.
Exchange lamps for another type.
Cause 2: Dimming principle and lamps do not optimally match.
For HV-LED: Check operation in another dimming principle, reduce connected load as
well if necessary.
For LV-LED: Check the lamp operating device and replace as necessary.
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 all outputs from the mains, switch-off the corresponding 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 all outputs from the mains.
Eliminate short-circuit.
9 / 11
82402712 10.07.2020

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.
