Error
possible cause / solution
1
Time-out in the positive alternation of the mains
voltage during operation.
Error in the voltage zero crossing circuit in charged condition (circuit T1,
power failures on the mains, charge not compatible with module...)
2
Time-out in the negative alternation of the mains
voltage during operation
Error in the voltage zero crossing circuit in charged condition (circuit T1,
power failures on the mains, charge not compatible with module...)
3
Time-out in the positive alternation of the mains
voltage during self test.
Error in the voltage zero crossing circuit in uncharged condition
(circuit T1...)
4
Time-out in the negative alternation of the mains
voltage during self test.
Error in the voltage zero crossing circuit in uncharged condition
(circuit T1...)
5
Mains frequency is too high.
Freq. > 62 Hz.
Check your local mains frequency. It should be 50 or 60 Hz.
There may be power failures on the mains.
6
Mains frequency is too low.
Freq. < 48 Hz.
Check your local mains frequency. It should be 50 or 60 Hz.
There may be power failures on the mains.
