Fault code tabel
Fault code:
(number of LED flashes.)
Fault: Possible cause:
5 Fault in the voltage zero-cross circuit - Fault on the lighting net work
- K8028 faulty.
6 Fault in the current zero-cross circuit - Load too small or not connected
- Load fuse blown
- K8028 faulty.
7 Phase shift fault!
Measured phase shift outside the limit value.
- Load too inductive
- Unloaded transformer.
8 Phase shift fault! (
The triac cannot be triggered.
- Load too inductive
- Unloaded transformer.
9 Voltage zero-cross fault with proportional motor
control.
- Fault on the lighting net work.
- Unsuitable load.
- K8028 faulty.

WARNING:
 The built-in fuse must always be replaced by an original type. Under no circumstances may the fuse exceed a current
rating of 2.5 A.
 Do not forget to connect the earth of each lighting point that is connected to the mains. The earth conductor must be
present, even if there is no earth terminal on the lighting point.
 The operating pushbuttons are always at mains voltage. They must always be suitable for the mains voltage used.
 Never connect a transformer to the output while the synchronous motor speed control is active
