5.4. Step 4: Basic commissioning parameters set up (using PQF-Manager)

In order to set up the basic commissioning parameters with the PQF-Manager, navigate to [/Welcome/Settings/Com-
missioning].The complete commissioning must be done at the first installation of a filter system and each time a filter
unit is added to an existing filter system.
If the window or some of its items are locked (i.e. a small
hardware and/or software lock has been engaged. Refer to Chapter 7 of the detailed manuals for more information on
these features and for guidelines on how to unlock the filter setting menus.
In the commissioning window, the following basic parameters have to be specified:
– The network characteristics:
The parameters to enter are the nominal network voltage, network frequency and filter synchronization mode. The
filter synchronization mode shall normally not be changed unless specifically instructed by the HITACHI ENERGY ser-
vice provider.
– The filter characteristics:
For a PQFS filter, this consists of setting up the filter connection mode: 3-wire (no neutral connected) or 4-wire (neu-
tral connected).
– The CT settings:
The CT settings can in many cases be automatically detected or can be entered manually.
automatic and manual CT detection procedure.
– The Rating parameter:
If the filter is installed at locations higher than 1000m /3300ft or is running under ambient temperature conditions
higher than 40°C/104°F, the filter has to be derated. For more information on how to calculate the derating required
and how to enter the rating value, refer to the detailed manuals provided on the USB key.
Remarks:
– Although the user requirements for harmonic filtering and reactive power compensation/balancing can be set up
from the commissioning window this should not be done before the filter has been started successfully for the first
time (Cf.
Section 5.6
and
– If digital I/O and/or the alarm contact have been cabled on the PQF-Manager, the appropriate software settings
have to be made. This has to be done in the 'Customer settings' menu ([/Welcome/Settings/Customer set.]). Refer
to the respective PQF manual for detailed information on how to set up digital I/O, alarms and warnings. In order
to achieve full redundancy with master-master filters, the digital I/O have to be cabled to all master units and all
the PQF-Managers have to be set up accordingly.
– In order to change the temperature unit used by the system, go to [/Welcome/Settings/Customer set./Temp unit].
– For setting up advanced filter functions such as the auto restart feature (after power outage), the filter standby fea-
ture (which stops the IGBTs when the load requirement is low), the system clock, the external communication pro-
tocol (Modbus or PC) and the software lock, refer to the detailed manuals. In order to achieve full redundancy for
the communication features in master-master filters, this function has to be cabled to all master units and all the
PQF-Managers have to be set up accordingly.
If the CTs have been set up correctly at this stage, go to step 6
of the CT connections, go to step 5
