Symptom Cause / State What to do
When selecting a
harmonic, the filter
attempts to identify it
but after a while it is
put in standby. The
letter ‘S’ appears in
the harmonics
selection list. The
harmonic is not
filtered.
The network conditions
do not allow for the
harmonic to be filtered at
present or there is a CT-
problem.
− Check the CT-setup.
− Reselect the harmonic
to see if the problem
persists.
− Leave the harmonic in
standby. The filter will
automatically restart
identifying/filtering it
when another harmonic
component is
successfully
(re)identified.
The ‘ACK. FAULT’-
message is present on
the PQF-Manager. The
alarm contact
switches on after
some delay.
The filter has stopped due
to an error.
