1. Setting Main CT Primary, Main CT Secondary, PT Ratio and Mode of control action.
In order to give actual voltage and current values in your system, Main CT Primary and
Secondary as well as PT Ratio should be set. Main CT Primary can be select from 5 to
5000. main CT Secondary can be select 1 or 5. PT Ratio can be select from 1, 3.7727, 4.0,
6.2727, 30, 60, 100, 200, 300, 600 and 1200.
For PF correction, there are four types of Control Action such as VAR, PID, SFIFO and
FIFO which are selectable at site. In case the control action is selected to VAR, Minimum
Bank, Capacitor CT and AUTOSENSING become relevant as programmable parameters.
However, these parameters are not applicable in case of FIFO or SFIFO mode control
action.
To set above parameters, proceed as follows:
Once in Programming mode,
1. Set Arrow (>) to the desired parameters using and keys and press key. Now
Arrow (>) starts blinking which means value of this parameter can be set now. Set desired
value by using and keys and again press key to save its value.
2. If other parameters need to be changed, do so using similar method. Else, press
key for about four seconds continuously. The unit will restart and enter into run mode.

Setting Capacitor CT Enable, Capacitor CT Primary and Secondary and Desired PF
In VAR control action mode, using capacitor CT, proper Bank KVAR can be sensed.
Capacitor CT Primary and Capacitor CT Secondary will be enable in case of CAP_CT_ENB
is set to YES. Capacitor CT Primary can be set from 5 to 5000. Capacitor CT Secondary
can be set to 1 or 5. The desired PF can be set to either LE
AD or LAG according to user’s
requirement. In case of LAG, the PF could be set from 0.800 to 1.000. In case of LEAD, the
PF could be setting from 1.800 to 1.999. e.g., the PF to be set for 0.998 LEAD should be
set as 1.998.
To set above parameters, proceed as follows:
Once in Programming mode,
1. Set Arrow (>) to the desired parameters using and keys and press key. Now
Arrow (>) starts blinking which means value of this parameter can be set now. Set desired
value by using and keys and again press key to save its value.
