Setting Up The Filter Characteristics - ABB PQFS Installation, Operation And Maintenance Instructions

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.
· Pressing
in the network characteristics setup menu will result into jumping to
the next step in the menu without the values entered being taken into account.
When involuntarily entering the menu, walk through the menu by pressing
repeatedly. This way the menu can be quit without modifying any values.

7.7.2.2 Setting up the filter characteristics

For modifying the filter characteristics (3-wire or 4-wire connection mode) and number of
units/unit ratings, go to [/Welcome/Settings/Commissioning/Filter charact.]
The filter may be connected in 3-wire mode (only phases connected) or in 4-wire mode
(both phases and the neutral connected). Also the filter may consist of up to 4 parallel
hardware units of the same rating. The filter connection mode must be adapted in software
to the on-site configuration. In addition, when the filter configuration is changed on site
(e.g. going from one connection mode to another), the filter setup has to be adapted
accordingly.
WARNING: Setting up a wrong filter configuration may lead to filter malfunction.
This should only be done by experienced commissioning engineers.
When entering the 'Filter characteristics' window, first the connection mode has to be
defined:
· 3-W: choose this mode when only the phases are connected. In this case, the
filter can filter harmonics that are flowing between phases and make phase to
phase balancing but cannot filter harmonics in the neutral nor make line to
neutral balancing.
· 4-W: choose this mode when both the phases and the neutral are connected. In
this case, the filter can filter harmonics between phases as well as harmonics in
the neutral, and can perform balancing of loads connected between phases as
well as connected phase to neutral.
Further note that:
WARNING: All hardware units in a master-slave filter arrangement must have the
same rating. Combining hardware units of different ratings in the same filter panel
will lead to hardware failure and/or inability for the filter to start up.
Remarks:
· The filter needs to be stopped before the unit ratings menu can be accessed.
Attempting to access the menu while the filter is running will result in a fault
message being displayed.
