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. 15 step LEDs indicate which step
is switched on. Detailled information about buttons, display,
alarm and capacitor step LEDs will be explained in the
coming sections.
POWER FACTOR CONTROLLER
RG3-15C/CS/CL/CLS
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.
RG3-15C/CS/CL/CLS power factor controller is designed
for reactive power compensation in single phase and 3-
phase systems. RG3-15C/CS/CL/CLS compensates each
phase separately and so, this makes RG3-15C/CS/CL/CLS
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.

:
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.
