The 'Pqf Operation - ABB PQFM Instruction Manual

The '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 Table 53 and Table 54.
For multi-master filters, this data can be obtained for each individual unit.

7.10.6 The 'PQF operation'

The 'PQF operation' ([/Welcome/PQF monitoring/PQF Operation]) parameter indicates
the total operating time of the filter (filter 'on').
The 'Fan operation' parameter indicates the total operating time of the fans cooling the
filter. The reset fan operation button resets the number of fan operation and should be
used after a fan is replaced.
For multi-master filters, this data can be obtained for each individual unit.
If a problem exists, an external intervention is required to solve the problem after which
the unit has to be reset by acknowledging the fault for the unit considered. After this,
the parameter value will be reset to 0.
Note: the reset of fan operation is protected by a password (default password is 1234).
If the user changes the password in [/Welcome/Settings/Installation
settings/Password], the "Reset Fan operation" password is changed as well.
