Cause
Communication problem
between the main controller
board and the external PC
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
– Ensure that the PQF-Link cable is
properly connected.
– Contact your ABB service provider.
– 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
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.
