Fault message on
7-segment
display
The fault or warning code is displayed in BCD format. The following display sequence
is adhered to (e.g. fault code 84):
The display switches over to the operating display following a reset or if the fault or
warning code once more resumes the value "0".
List of faults
A dot in the "P" column means that the response is programmable (P83_ Fault
response). The factory set fault response is listed in the "Response" column.
