5. TROUBLESHOOTING
Possible causes if the error indication LED and the load LED blink:
- the lamp is defective
- the load is not connected
Possible causes of dimmer malfunction, no LED indication:
- no power on the mains
- there is no control signal
- thermal protection is activated
- combination of the above causes.
- The dimmer is provided with a thermal protection. If the
temperature rises too high, the light is automatically dimmed
to ±40%. If the temperature continues to rise, the dimmer is
switched off. If this happens:
- check whether the load is not too high. Take into account the
reactive power of ferromagnetic transformers.
- check the temperature in the distribution board (max. 35°C).
If the temperature is too high, provide additional ventilation.
Provide sufficient space at the top of the board. Place, if
necessary, a ventilator.
- If several modules are installed next to each other, provide
min. 1 module distance via adapted blank plates.
The dimmer is automatically switched on again as soon as the
temperature has dropped sufficiently.
- The error indication LED continuously blinks or lights. This
indicates:
- overload
- overvoltage or overcurrent
- short circuit
- the load is not dimmable, neither in phase control, nor in
reverse phase control.
