LED indications in case of error:
When the CPU detects an error, LD1 (green) lights up continuously, whereas LD2 (red) repeatedly emits a
series of flashes.
We advise you to briefly interrupt the supply voltage and evaluate the situation.
The “MON” connection on the PCB is only used by our technical department for purposes of repair and diagnosis.
Flashes
LD2
Error
Possible cause
1
Time out in the positive alternation of
the mains voltage
error in voltage zero-crossing circuit (T1, ...)
2
Time out in the negative alternation
of the mains voltage
error in voltage zero-crossing circuit (T1, ...)
3
Triac triggering time out
- Triac defective ?
- Light source defective ?
- T2 defective ?
- Load doesn't conform to specifications ?
4
Phase shift is too great
- Load behaves too inductively ?
- No load connected ?
- No load on transformer (because of defective lamp ?)
- Load not conform ?
