Figure 88: PQF error treatment procedure in flowchart format
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.
If ‘ACK. FAULT’ is present on the PQF-Manager display, look at the ‘Armed’ indicator
(By default mapped to the 4
th
digital output of the PQF-Manager) to know whether
the filter will restart automatically after clearance of the problem or not.
‘Armed’ indicator ON: The filter waits for the problem to disappear and then restarts
automatically (unless the user acknowledges the fault).
‘Armed’ indicator OFF: The filter is permanently stopped and the customer has to
solve the problem, acknowledge the fault and restart the filter manually.
