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; the 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 been switched off.
Cause 1: overheating protection has tripped.
Disconnect all outputs from the mains, and switch off the corresponding circuit breakers.
HV-LED trailing-edge phase control: Reduce the connected load. Exchange lamps for another 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 the 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, and reduce the connected load as well if necessary.
Exchange lamps for another type.
The response of the surge protection can be signaled by sending a short- circuit telegram or can be determined by polling the “short-circuit” communication object.
Cause 3: short-circuit in the output circuit
Disconnect all outputs from the mains.
Eliminate short-circuit.
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 a 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, and replace a light bulb. For inductive transformers, check the 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 cancer 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 are off and not possible to switch on
Cause 1: bus voltage failure.
Check bus voltage.
Luminaires flicker or buzz, proper dimming is not possible, device buzzes
** Cause: wrong dimming principle set
Installation or commissioning error. Disconnect device and luminaire, switch off the circuit breaker.
Check installation and correct.
If the wrong dimming principle has been preselected: Set the correct dimming principle.
If the dimming actuator calibrates itself incorrectly, e.g. with highly inductive mains or long load cables: preselect the correct dimming principle with commissioning.
LED lamp is dimly lit when the dimmer is switched off Cause: the 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.
