POWER FACTOR CONTROLLER

RG3-12C/CS

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.

SAUE

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 Cosj and Target Cosj2 Value Setting

The device has two target Cosj values as Cosj ve Cosj2.

If there is a voltage between 110-250 VAC present on the generator inputs

of the device, the target Cosj set on the device is deactivated and target

Cosj2 is activated. Then the device starts the compensation according to

target Cosj2. This operation mode continues until the voltage on the generator

input is disappeared.

Target Cosj ve Cosj2 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 Cosj 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 Cosj and Cosj2 values may be entered between 0,800 ... -0,800.

Negative values represent Capacitive Region, positive values represent Ýnductive

Region.

3.2.a Inductive / Capacitive Cosj and Cosj2 Setting

Press the SET button for 3 sec. in order to enter to the menu.

Using the DOWN / UP buttons, find the Target Cosj (COS or

COS2) menu option.

Press the SET button to enter the Target Cosj menu.

Using the UP/DOWN buttons, enter a Cosj value between -

0,800 ... 0,800 and press the SET button.
