  • Page 2: Introduction

    INTRODUCTION The DCRG8 and DCRG8IND automatic power factor controllers have been design incorporating the state of the art in the functions required for power phase correction applications. Made with a dedicated housing of extremely compact dimensions, DCRG8 and DCRG8IND combine a modern front panel design with practical fitting and the possibility of expansion at the back, where modules of the EXP series can be housed.

  • Page 3: Operating Modes

    – Another window will then be displayed, prompting you to set the CT primary winding, something usually referred to the installer or end user. Even in this case, it activates a direct access to the setting of the relevant parameter P02.01. –...

  • Page 4: Password Access

    FRONT BUTTON LOCK The front buttons can be locked to prevent involuntary access to the pages of DCRG8 and DCRG8IND. To enable the button lock, go to the main page and then, holding down the ◄ button, press the ▲ button three times then the ▼ button twice. A pop-up window will appear on the display to indicate that the buttons are locked.

    – The graph is automatically updated about every second. EXPANDABILITY – Thanks to the expansion bus, DCRG8 and DCRG8IND can be expanded with additional modules of the EXP series. – It is possible to connect a maximum of 4 EXP… modules at the same time.

  • Page 7: Additional Resources

    – The two channels can communicate at the same time. – By activating the Gateway function, it is possible to have a DCRG8/DCRG8IND equipped with an Ethernet port and a RS485 port which works as a “bridge” towards the other DCRGs provided with the RS485 port only, and so obtain a saving (one Ethernet access point only).

  • Page 8: Limit Thresholds

    MASTER-SLAVE CONFIGURATION – To further extend the flexibility of DCRG8/DCRG8IND, the Master-Slave function has been made available, which for high-powered systems allows a cascaded series of panel to be set up, each with its own controller and corresponding capacitor banks.

  • Page 9: Power Factor Correction By Single Phase - Sppfc

    Example 2 (Application in series): A system with 18 steps of 40kvar each is divided into three identical panels, each with 6 steps, 240kvar in total. For each slave panel, the 8 relay outputs of the controller are used as follows: the first six for the steps (OUT1...6), the seventh for the cooling fan (OUT7) and the last for the alarm (OUT8). On the master panel, there will be 18 logic 40kvar steps.

    USB programming dongle type CX01 PARAMETER SETTING (SETUP) WITH PC – Xpress configuration and remote control software can be used to transfer parameters (previously set) from the DCRG8 and DCRG8IND to a PC hard disk and vice versa. – Parameter transfer from a PC to the DCRG8 and DCRG8IND may be partial, i.e. only the parameters of specified menus will be transferred.

    – Remember that, solely for the setup data that can be edited using the buttons, a backup copy can be made in the DCRG8 and DCRG8IND’s EEPROM. This data can be restored, when necessary, in the work memory. The data backup copy and restore commands can be found in the commands menu.
