To clear a fault message power the unit down and then up again. Wait for minimum 30 seconds
before you power the inverter up again.
Fault memory:
The last four faults are saved and can be read out as display parameters 95 ERR1 in the VAL menu
branch, using the FBG 01 keypad. Details saved are the type of error and the operating time up to
fault occurrence.
If the FBG 01 control unit is plugged in at the time the fault occurs, display parameters VAL 12 F, 13 V,
14 IS, 15 IW and 17 VZK are frozen at the time the fault occurs and can be read out until the unit is
reset.
