Cause
The system detected an
overtemperature of the
main controller board.
Internal system error.
Internal system error.
The DC capacitors could
not be charged.
Two or more units in a
filter system have the
same CAN_ID.
The communication
through the CAN bus
between units is not
working properly.
What to do
- Verify the ambient temperature and
the cooling of the filter (dust filters,
fans, heatsinks ...).
- If the ambient conditions and the
filter cooling is ok, the main control
board is suspect. Contact your ABB
service provider. The main control
board may have to be replaced.
Reset the filter by switching off and on
the power. If the problem persists,
contact your ABB representative. The
controller card must probably be
replaced or the controller software
upgraded.
Reset the filter by switching off and on
the power. If the problem persists,
contact your ABB representative. The
controller card must probably be
replaced.
- Measure the three line voltages and
check if they are within limits.
- Verify the preload circuit.
- Inspect the DC-bus for traces of
damage that may have caused a
short circuit on the DC-side of the
IGBT-module or on the DC voltage
measurement board.
- Check the CAN_ID of the different
units in the set of filters: each unit
has to have one unique CAN_ID on
the DIP switch S5-1 to S5-3.
- Reset the filter by switching off and
on the power. If the problem
persists, contact your ABB
representative. The controller card
must probably be replaced.
- Check the RJ-45 cables between
modules.
- Check the termination for the CAN
bus: both (and only) the ends of the
bus must have the DIP switch S5-4 in
the "set" status.
- Reset the filter by switching off and
on the power. If the problem
persists, contact your ABB
representative. The controller card
must probably be replaced.
