LD1
Error Possible cause / solution
1 Time-out in the positive alternance
of the mains tension Error in the voltage zero crossing circuit (T1, …)
2 Time-out in de negative alternance
of the mains tension Error in the voltage zero crossing circuit (T1, …)
3 Time-out triac control - Faulty triac?
- Faulty power point?
- T2
defect?
- Charge does not comply with specifications?
4 Phase shift too big - Charge behaves too inductively?
- No charge connected?
- Transformer uncharged (by faulty lamp)?
- Not-compatible
charge?
LED INDICATIONS DURING FAULT REPORT :
When the CPU detects an error, LD1 (red) can give us an indication on the nature of the problem. LD2
(yellow) will then burn continuously while LD1 (red) will repeatedly flash a number of times.
We suggest interrupting the mains tension for a moment and evaluating the situation.
The K8038 can be restarted without switching the tension off: keep the control button pressed until both
LEDs go out (approx. 10 seconds).
