POWER FACTOR CONTROLLER
RG3-12C/CS
7
The last capacitor step number is entered between 1-12 for RG3-12C/CS
in this menu. For example; if this number is entered as 8, only the steps 1
through 8 will be operated by the device. After this setting is changed, the
device must be de-energised and re-energised. If not, the active steps
which aren’t selected may stay activated.
NOT: When program 10(PS-10) is selected, it is better if the last capacitor
step number is set as 12. When program 10 is selected, the activation
and deactivation of the steps without a capacitor connected to them
is not an issue because with program 10, the connection for these
steps can be set as “oFF“. The last capacitor step number should be
used with the switching sequences other than the 10th.
3.3 Last Capacitor Step Number Setting
Press
“SET”
button for 3 sec. in order to enter to the menu.
Using the “UP/DOWN” buttons, find the step number(StEP) menu
option. When the step number setting menu is selected, the STEP
LED will turn on.

If you want to leave the setup menu without making any other
changes, press the
“ESC” button until “SAVE SEt yES” shows
on the screen. If you want to save the changes, press the “SET”
button. If not, press the “ESC” button.
Press the “SET” button to enter the last capacitor step number.
Using the “UP/DOWN” buttons, enter a last capacitor step number
between 1-12 and press the “SET” button.
Using the “UP/DOWN” buttons, enter to another menu option
which you wish to change. If you are not going to change any
more settings, press the
“ESC” button.
3.2 Target Cos
j
and Target Cos
j
2 Value Setting
The device has two target Cos
j
values as Cos
j
ve Cos
j2.
If there is a voltage between 110-250 VAC present on the generator inputs
of the device, the target “Cos
j
” set on the device is deactivated and target
“Cos j 2” is activated. Then the device starts the compensation according to
target Cos
j
2. This operation mode continues until the voltage on the generator
input is disappeared.
Target Cos
j
ve Cos
j2
values may be adjusted between “0,800 ... -0,800” by
the user. Negatif values represent
Capacitive
region and positive values represent
Inductive
region. RG3-12C/CS tries to match the systems Cos
j
to the user
defined value. If the need for compensation of a phase is lower than 0,625 times
of the capacitor which is connected to that phase, the device doesn’t activate or
deactivate any steps and stays at NORMAL status. If there aren’t any connected
capacitors on that phase, the device operates according to one-third(the power
for that phase) of the 3-phase capacitor with the lowest power value.
Target Cos j and Cos j2 values may be entered between “0,800 ... -0,800”.
Negative values represent
Capacitive Region,
positive values represent
Ýnductive
Region
.
3.2.a Inductive / Capacitive

j
and Cos
j
2 Setting
Press the “SET” button for 3 sec. in order to enter to the menu.
Using the “DOWN / UP” buttons, find the Target Cos
j
(COS or
COS2) menu option.
Press the “SET” button to enter the Target Cos
j
menu.
Using the “UP/DOWN” buttons, enter a Cos
j
value between -
0,800 ... 0,800 and press the “SET” button.
Using the “UP/DOWN” buttons, enter to another menu option
which you wish to change. If you are not going to change any
more settings, press the
“ESC” button.
If you want to leave the setup menu without making any other
changes, press the
“ESC” button until “SAVE SEt yES” shows
on the screen. If you want to save the changes, press the “SET”
button. If not, press the “ESC” button.
