Page 9: Introduction To This Manual
1.1. What this chapter contains This quick start-up guide is intended to assist the users in installing and commissioning of PQF range of filters. This is a simplified version of the detailed operation, installation and maintenance manual available in a CD-ROM supplied with your filter.
Page 10: Knowing Your Filter
3. Knowing your filter The PQF range of active filter is modular in design. It consist of mainly an IGBT based inverter (current generator) and digital control system together with a user interface (PQF Manager). A simplified schematic with external connec-...
Page 11 All hardwired connection such as digital input/output, communication ports etc. are specific to a PQF-Manager except for those connected to the PQF-Manager of the real master. The hardwired connection for digital input/output and communication connections to master PQF-Manager is effective for the entire filter system.
Page 12: Location Of The Main Pqfi Components
Terminals for heat extraction fans The PQF Main controller board has connectors which are predominantly pre-wired for use within the filter. However, it also contains a DIP-switch used to set the identification address and CAN bus connectors for use in a multi-module filter arrangements.

Location of the main PQFS components Figure 12 shows a picture of the PQFS without cover panel.
Page 14: The Pqf Main Controller
CT signals to different units (master or slave) must be routed through daisy chain principle with return path. If second unit is a slave unit, it will not have a PQF-Manager. If second unit is a master unit, it will have a PQF-Manager.
Page 15 All slave units have their own AC-connection and breaker (or contactor) protection. A PQF active filter system consists of up to 8 units. Additional units to the first master unit may be master or slave units. Slave units do not have a PQF-Manager.
Page 16: The Pqf-Manager User Interface
In multi-unit filters consisting of only one master, only the master has a PQF-Manager. In multi-unit filters consisting of more than one master, all the master units have a PQF-Manager. However, only the PQF-Manager that is connected to the master unit which has the overall control will be active. The PQF-Manager in- stalled on the units operating as "slaves"...
Page 17 – Selection of main filter settings or auxiliary filter settings (e.g. different filter settings for the day and for the night) The PQF-Manager is used to associate the required functionality with the chosen digital input. The digital inputs can also be disabled.
Page 18 Maximum continuous dc rating: 110 Vdc/0.3 A; The common is rated at 9A/terminal, giving a total of 18 A. Information on cabling the digital output contacts and on setting up the digital outputs with the PQF-Manager is given in the detailed manuals.
Page 19: Upon Reception
– Pin L: CAN Low signal – Pin Shield: shielding The CAN bus wiring terminates into the PQF-Manager connection plug and is subsequently routed to the main con- trol. It is used for PQF internal communications only. Power supply terminals The PQF-Manager power supply is provided by the filter itself.
Page 20 – Remove the right side of the protective cover and put it aside (see Figure 19 item 2) – Unplug the PQF-Manager from the main system (see Figure 19 item 3). Then the protective cover can be safely put aside.
Page 21: Identification Tag
Before connecting the filter to an already existing master or in case of multiple units, the DSP and µc software ver- sions of both filters have to be checked. If the versions are different, contact your HITACHI ENERGY representative 4.2. Storage...

• the electrical drawing and connection diagram • the communication cable needed for multi-unit operation Any loss or damage should be notified immediately to your HITACHI ENERGY representative. WARNING: Make sure that the filter is installed at a location where no conductive dust is present. Conductive dust when distributed in the filter panel may lead to equipment failure.
Page 23: Step 2: Setting The Address Of Each Unit In A Multi-Unit Filter And Terminate The Can Bus
– Check the tightness of all connections including power cable connections section and tightness, CT connections, digital I/O connections on the PQF-Manager and the control board connections inside the filter. 5.2. Step 2: Setting the address of each unit in a multi-unit filter and terminate the CAN bus Each filter is defined by a filter address.

Page 27: Step 4: Basic Commissioning Parameters Set Up (Using Pqf-Manager)
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.
Page 28: Step 5: Automatic And Manual Ct Detection Procedure
PQF connection diagram Figure 22 shows the standard connection diagram for the PQF. It must be noted that: – L1, L2 and L3 rotation must be clockwise. – The CTs must be on the supply (line) side of the PQF.
Page 29: Automatic Ct Detection Procedure
– For deselecting the load balancing option of the main filter settings disable the option ‘Balance load’ in [/Wel- come/Settings/Customer set./Main settings/Main PFC/Bal.].

– For deselecting the load balancing option of the auxiliary filter settings disable the option ‘Balance load’ in [/Wel- come/Settings/Customer set./Auxiliary settings/Aux. PFC/Bal.]. For more information on the main and auxiliary settings concept, refer to the detailed PQF manuals. 5.7. Step 7: Start the filter Close the filter door (fit the filter top cover in the PQFS filter) before starting the filter.
Page 31: Step 9: Set Up The User Requirements
At this stage, verify the functioning of the settings made for the digital I/O if possible (e.g. remote control, local start/stop buttons). Remarks: – Refer to respective PQF manuals for troubleshooting problems. – Filter running at 100% load while RMS current rating is not attained. STATUS...
Page 32 When consulting the harmonic selection table of the PQF-Manager, harmonics put in ‘standby’ can be recognized by the label ‘S’ that is displayed in the harmonic selection column (which reads otherwise either ‘Y’ or ‘N’).
Page 33: Commissioning Report
– In installations where 2 non-compatible masters, such as a PQFM with a PQFS or two PQF of different genera- tions, are connected to the same CT, select different harmonics on both units. 5.10. Commissioning report The commissioning report is designed to help the person in charge of the commissioning.
Page 34: Filter Identification
Applicable only for PQF range Read on identification tag located at the outside of each cubicle door. After the filter has been commissioned, navigate with the PQF-Manager to [/Welcome/User interface/About PQF]. Select whether this unit is a master (M) or a slave (S) unit.
