11.4.1 Verification of the PQF-Manager status and the system LEDs

As a first phase of troubleshooting make a record of the information provided by the
PQF-Manager:
−
'ACK. FAULT' message present of not.
−
Filter event log information messages.
−
Alarm horn on or not?
−
Status of the digital output contact monitor.
The most recent messages are shown first in the event log.
Refer to
the corresponding troubleshooting tips. Note that for troubleshooting it may
be necessary to remove the filter right protective cover. Always remove power
to the units and allow time for the DC capacitors to discharge (min. 25 mins)
before removing the filter cover.
When the filter right cover is removed and power is supplied again to the filter, the
status of the control card LEDs can be monitored.

Provide the data provided by the PQF-Manager and the LED status information to the
ABB service provider when discussing a potential filter problem.
