POWER FACTOR CONTROLLER
RG3-12C/CS
2. INSTALLATION OF RG3-12C/CS
When RG3-12C/CS is energised for the first time, if the power value
of any phase is negative, it switches on&off the first capacitor step
automatically to recognize the connection error and records the connections.
Later, automatic setup (Refer to page 6 - Automatic setup) is selected
from the menu in order to recognise the connections and connected
capacitor steps automatically.
After automatic recognition, RG3-12C/CS checks all capacitor step
values. If variable loads exist in the system, these variable loads must be
disconnected first and then automatic setup process must be done.
Otherwise, power factor controller may not measure capacitor step powers
correctly. Capacitor step powers and connection types also can be entered
to the power factor controller manually.
(
Refer to page 10 - Setting of the capacitors connection and power values
)
After recognising the capacitor step powers, target Cos
j
value is set in order to start the compensation. Factory set value for target
Cos
j
is ind. 1.000 and Cos
j2
is ind. 0.900
Note: PFC decreases the switching on&off time to 3 seconds in
Automatic Setup mode but discharge time is not changed. After the
automatic setup process, set values become valid.
After the device is energised, it finds connection errors and corrects
them automatically. Power values of the capacitor steps are measured
automatically according to program selection. If PS-10 program is
selected, power values of all capacitor steps are measured (Refer to
Program Section). If any other program is selected, device measures
first capacitor step value and then calculates other capacitor steps
according to the selected program. For this reason, a 3-phase capacitor
must be connected to the first step. Single phase and/or 3-phase
capacitors can be connected in any order to the other steps. After the
device calculates and saves the capacitor values, it will switch them on
and off when needed.

3.1.a Manuel Operation Mode Setting
RG3-12C/CS has two operating modes which are automatic
and manual. The operation mode is choosed by selecting the
Auto Operati option as
on
(automatic mode) or
off
(manual
mode).
Manual mode is used for test purposes. In this mode,
capacitor steps are switched on&off to test relay outputs. In
manual mode, capacitor steps are switched on with
SET
button and switched off with
ESC
button. The conditions of
the steps can be monitored from the 12 step LEDs on the front
panel. C+ LED lights up when a step is switching on and C-
LED lights up when a step is switching off. Factory set values
for switching on (t-on) and switching off (t-of) time are 10 sec.
These values can be changed by the dELy menu (
Refer to
Switching on&off Time for Capacitor Steps and Discharge
Time Settings
). In manual mode; step numbers, which will be
switched on&off, can be programmed in StEP menu (
Refer
to Step Number Setting
). Even if manual mode is selected,
device switches to automatic mode after 5 minutes continues
to operate in this mode.

Press the
SET
button for 3 sec. in order to enter to the menu.
Press
SET
button to set the parameters in Auto menu option.
Press
UP
or
DOWN
button. To select the automatic operating mode,
choose
on
with
UP
or
DOWN
buttons and press
SET
button. To
select the manual operating mode, choose
oF
with
UP
or
DOWN
buttons and press
SET
button.
The first setting in this menu is the operation mode(Operati). The operation
mode of the device is selected according to this options
on
or
off
selection.
Press
SET
button to change this setting.
Numerical values of the parameters are set via buttons in the
display. The blinking digit indicates which digit will be set.
Numerical value of the related digit is increased or decreased via
UP
or
DOWN
button. To set the next digit,
SET
button is
used. To go back to the previous digit,
ESC
button is used
.
When automatic mode is selected, AUTO/MAN LED lights up
continuously.
When manual mode is selected, AUTO/MAN LED blinks.
Warning: Device warns user by blinking (short ON, long OFF)
the LED of the capacitor steps which will be switched on. Also
device warns user by blinking (long ON, short OFF) the LED
of the capacitor steps which will be switched off.
For proper operation; 3-Phase, neutral, voltage and current terminals
must be connected as shown in the connection diagram. Device does not
work properly without 3-phase connection.
After the connection of the current and voltage lines, connect the
capacitors to the device. The most important point is connecting a 3-phase
capacitor to the first step. Remaining single phase and 3-phase capacitors
can be connected to the other steps in any order and power values.
After the connection of capacitor steps; J-Type 0-400 V thermocouple
must be connected if temperature measurement function will be used
(Temperature measurement feature is optional).
Lastly, computer communication connection must be done.
Do not energise the device before verifying the connections.
Always connect a 3-phase capacitor to the 1st step.
