Cause
Explanation
Incorrect signal from the Hall-ICs,
error in the commutation.
The device is provided with a built-in Following a shut off, a start up
phase-monitoring function for the
mains supply. In the event of a mains 15 seconds, if the voltage supply is
interruption (failure of a fuse or
mains phase) the unit switches off
after a delay (approx. 200 ms).
Function only when load for the con-
troller is high enough.
If after 8 seconds cummutation no
