Manual Power Quality Filter PQFM
WARNING: Under no circumstances close the main contactor manually. Failure to
adhere to this guideline may result in physical injury and/or in filter damage.
Normally, the commissioning engineer has set up the filter and the desired filter
requirements. As a result, the user only has to start and stop the filter. Detailed
information on the filter start/stop menu can be found in
Section 7.7
9.2.1
Starting the filter with the PQF-Manager
In order to start the filter with the PQF-Manager follow the instructions given below:
−
Ensure that power is supplied to the filter and that the filter auxiliaries are ‘on’
(auxiliary fuse holder contains good fuses and is closed).
−
Press
on the PQF-Manager 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 visible.
−
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.
Remarks:
−
If your filter is equipped with bulb indicators, the bulb corresponding to the
present filter state will be on.
−
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. In filter systems consisting
of more than one unit, an ACK. FAULT message will only occurs when all the
masters in the system have failed.
−
In filter systems consisting of more than one master, one master unit is the main
one and the other units behave as slaves. The PQF-Manager of the main master
unit has full functionality and can be used to control the complete system. If the
main master unit fails, then another master unit will assume the role of main
master unit. The order in which master units assume control has been determined
at the moment of commissioning.
−
If some units of a multi-unit filter system do not start, this implies that the units
concerned are in error. Refer to [Welcome/PQF Monitoring/Status of units] to
identify the unit that is at fault and for which reason. 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
