Manual Power Quality Filter PQFS Commissioning instructions 155
WARNING: Under no circumstances close the main contactor manually. Failure to
adhere to this guideline may result in physical danger and in filter damage.
With all harmonics and reactive power compensation/balancing deselected, you can
start the filter.
In order to do this with the PQF-Manager:
− Press repeatedly until the ‘Welcome’ screen is displayed.
− Highlight the filter start/stop menu (‘PQF’ item in the list). In this menu, the
‘START’ indication should be present.
− Press . The filter will ask confirmation and then it will start. The main
contactor should close within 30 seconds. One second after closing, the IGBTs
will start and the filter will work under no load condition.
− The ‘START’ indication in the start/stop menu changes in a ‘STOP’ indication once
the filter is running.
Detailed information on the filter start/stop menu can be found in Section 7.7.
Remarks:
− If the start/stop menu reads ‘ACK. FAULT’ (i.e. ‘acknowledge fault’), the filter has
encountered a fault that needs to be corrected before the filter can be started.
Refer to Chapter 11 for troubleshooting the problem.
− If the filter when activating the start menu displays a message to indicate that it
is remote control mode, the filter either has to be started by remote control or
the remote control mode has to be deactivated. More information about the
remote control functionality is given in Section 6.12.1 and Section 7.9.1.4.
− If one of the units in a multi-unit filter system does not switch on, the unit
considered is in error. Refer to [/Welcome/PQF Monitoring/Status of modules])
to find out about the problem.
8.9 Step 8: Generate filter load
Once the filter is connected to the supply and is running, some filter load can be
generated to verify if the filtering is performing well.
When a harmonic load is present, the filtering performance can be tested by selecting a
harmonic, e.g. of order 11, and verifying if it is filtered properly.
− For setting up the filter’s main harmonics selection go to
[/Welcome/Settings/Customer set./Main settings/Main harmonics].
