Cause
IGBT defective
Note:
Monitoring only works when the load resis-
≥
tance is so low that
controller nominal current (max. load cur-
rent) is flowing.
Device temperature is higher than 100 °C
(Excess temperature)
Device temperature is higher than 105 °C.
Device is too hot, output level is reduced!
(Limited power due to excess temperature)
DC intermediate circuit voltage is not with-
in specified tolerance range
v Chapter 10.1 "Voltage supply, load
current"
Input current too small for the set measur-
ing range.
Input voltage too small for the set measur-
ing range.
No connection to Modbus master or Mod-
bus master is inactive.
This message appears when the
power required by the setpoint specifica-
tion can no longer be reached with the load
present.
The firing pulse inhibit has been triggered
via a PLC level.
No power from the power controller.
The current monitoring module has sig-
naled an excessive peak current. To pre-
vent destruction of the device, a firing
pulse inhibit is briefly triggered.
The firing pulse inhibit has been triggered
via an interface.
Remedy
The device must be returned to JUMO
for repair.
