Setting Up The Filter Characteristics - ABB PQFM Instruction Manual

WARNING: If the filter nominal frequency is changed to the wrong value, the filter will
refuse to start indicating a frequency error in the event logging window.
- The active filter synchronization mode (Synchro Mode): by default single phase
synchronization is used (Single ph.). In exceptional circumstances this may not
be adequate. In that case choose three phase synchronization (Three ph.).
WARNING: This parameter shall only be changed by experienced commissioning
engineers or after advice from the ABB service provider. Using the wrong synchro
mode will lead to filter malfunctioning.
Remarks:
- After going through the network characteristics menu, the filter system will be
automatically reset after which the new values will be taken into account.
- The filter needs to be stopped before the network characteristics menu can be
accessed. Attempting to access the menu while the filter is running will result in
a fault message being displayed.
When involuntarily entering the menu, walk through the menu by pressing the
-
button or following the complete menu. This way the menu can be quit
without modifying any values.
