After the problem is solved the system has to be manually reset (fault
acknowledgement) before normal operation can be resumed.
· In general the occurrence of transient faults is no problem for the proper
operation of the active filter. Only when an error becomes 'critical', a problem
may exist.
A fault is considered critical if after occurrence, it cannot be successfully
automatically cleared by the system within a reasonable time. The time frame
considered depends on the error type.
In practice the word 'Critical' will appear in the 'Event logging' window if the
system has detected a critical error. The user can then backtrack in the logging
window to see which errors were already present in the previous events, to know
which is/are the critical error(s).

The 'Active warnings' menu [/Welcome/PQF monitoring/Active warn.]

The 'Active warnings' menu is constantly updated by the system. It shows at any time the
warning conditions set up by the customer that are met. For more information on setting
up the programmable warnings, refer to
Table 48 shows an overview of the warning messages that will be displayed and the
corresponding warning condition.
For multi-master filters, this data can be obtained for each individual unit.
Table 48: Warning messages that can be displayed by the PQF-Manager and corresponding
Warning condition

The 'Total number of errors' menu [/Welcome/PQF monitoring/Number of errors]

The 'Total number of errors' menu keeps track of all the errors that have been recorded
since the controller system has been initialized at the production stage. The errors that
have occurred the most are listed first. Errors that have not occurred are not listed. For an
explanation on the errors listed, refer to the
For multi-master filters, this data can be obtained for each individual unit.
7.8.6

The 'PQF operation' and 'Fan operation' parameters

The 'PQF operation' ([/Welcome/PQF monitoring/PQF Operation]) parameter indicates
the total operating time of the filter (filter 'on').
The 'Fan operation' ([/Welcome/PQF monitoring/Fan Operation]) parameter indicates the
total operating time of the fans cooling the filter.
For multi-master filters, this data can be obtained for each individual unit.
7.8.7

The 'Trip. Phase' parameter

The value shown in the menu is by default 0. If a trip due to an overtemperature occurs,
the value will become 1 for the unit in which the problem occurred.
