INTRODUCTION
The DCRG8F automatic power factor controller has been designed incorporating the state of the art in the functions required for dynamic power factor correction applications. Made with a dedicated housing of
extremely compact dimensions, DCRG8F combines 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. The LCD graphic
display permits a clear and intuitive user interface.

FIRST POWER-UP
– At the first power-up, the controller may ask the user to set the clock-calendar (RTC), in case it is not operational.
– Then a window will appear asking to specify the language you want to use for display navigation. Press OK (
✔
) for direct access to the parameter P01.01 for the selection of the language.
– 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.
– The above-given procedure will be repeated every time the device is powered up until the CT primary value is set in parameter P02.01.
