FAQ during Commissioning:
1)
No indication AUTO
PFC is stopped
Cause: manual operation, SETUP/100/PFC = OFF or HOLD,
temperature is too high, current < 15mA, voltage oder THD U is out
of tolarance.
2)
Indication U ALARM
"
voltage out of tolerance
Check settings for nominal voltage (SETUP/Un) and
voltage transformer (SETUP/Pt)
3)
Indication I Lo ALARM
"
current < 15mA
Cause: connection error of CT; short-link of CT is not removed; CT-
ration is too big compared to real current; no current
4)
