gas module
Error 03.zzz Examples:
Error 03.128 128 = Error on the gas module
Error 03. 5 5 = 4 + 1

Overcurrent (FC output
recognition current
on the FC stays for a
long time
above the
rated
current) e.g.
in the event
of smaller
overloads
Examples:
5 = Error on the frequency converter 1 and motor temperature too high -
36 = 32 + 4 Overcurrent recognition on the FC1+ Electronic temperature of
the FC1-
0 = FC2 is ok
32 = Error on the frequency converter 2 -
0 = FC1 is ok -
144 = 128 + 16 Motor was stopped because of error + FC output current
remains for a long time above the rated current
