1.2 Front Panel
On the front panel; 3 display lines with four digits which consist of 7
segments, 4 buttons, alarm, capacitor step and display LEDs exist.
Measured parameters are observed in the related displays. Displayed
values for related parameters are selected via indicator leds. When an
alarm occurs, related alarm LED blinks. 12 capacitor step LEDs indicate
which capacitor step is switched on. Detailled information about buttons,
display, alarm and capacitor step LEDs will be explained in the coming
sections.

:
In the observation mode, they are used for
switching between observed parameters. In
the programming mode, they are used for
browsing the menu choices and changing
the parameter values.
In the observation mode, it is used to switch
between harmonic measurement mode and
instant value measurement mode. In the
programming mode, it is used to return to
the previous menu or exit without saving any
committed changes.
In the observation mode, it is used to show
the harmonic value of the measured
parameter. If it is pressed for 3 seconds,
programming mode appears. In the
programming mode, it is used to enter to a
menu or confirm the data entry.
1. INTRODUCTION
1.1 General Information
In todays world, the reactive loads on a network continue to increase with
the contracted power rise. The increase of the power on transformers,
transmission lines and generators caused a rise in the reactive power levels
just as much and maybe more than the active power levels. To prevent any
overloads and under voltage conditions, the compensation of the reactive
loads became a necessity in todays energy network.
Power factor controllers monitor the reactive power of a plant and try to
match the power factor value which is defined as the ratio of the active
power(W) to the apparent power(VA) to a power factor valuewhich is defined
on the device by the user.
RG3-12C/CS power factor controller is designed for reactive power
compensation in single phase and 3-phase systems.
RG3-12C/CS compensates each phase separately and so, this makes
RG3-12C/CS series a unique solution for unbalanced load compensation.
In order to achieve this feat, single phase and 3-phase capacitor steps
must be connected to the device at the same time.

1) Panel cut-out dimension must be 139 mm x 139 mm
(Type PR16).
2) Before installation, remove the mounting brackets.
3) Mount the device to the front panel.
4) Insert the mounting brackets.
5) Voltage and current terminals are designed for cables
with a cross-section of 2,5 mm
2
but these terminals are
suitable for cables with cross-sections up to 4 mm
2
.
6) CAT5 cable is recommended for RS-485 input terminal.
Excessive force can damage the device.
Turn the screw into the terminals and tighten until the
RG3-12C/CS is secured in place.
