1) AUTO :

This automatic switching program uses intelligent switching sequence. The step switching sequence is not fixed and the

program automatically select the most appropriate steps to switch in or out in order to achieve shortest reaction time with

minimum number of steps.

For equal ageing of the capacitor and contactors, the program will select the least used step to be switched in if there are

two equally rated steps.

Under this switching program, the power factor regulator automatically detects the CT polarity during power up. Once this

polarity reference is fixed, any subsequent re-generative power condition detected.No need for external capacitor CT.

2) MANUAL :

When this switching program is selected, the capacitor steps are controlled manually by the "UP" or "DOWN" keys.

The "UP" key will connect the capacitor step and "DOWN" key will disconnect the capacitor step.

Steps are switched in a rotational manner based on first-in-first-out basis. No need for external capacitor CT.

3) ROTATIONAL :

This switching program is similar to the manual switching method and it is based on rotational first-in-first-out sequence.

Unlike the manual switching program, this option will automatically switch in and out the capacitors according to the

targeted power factor, sensitivity setting and the reconnecting time setting. No need for external capacitor CT.

4) KVAR RUN :

This parameter relay switching is based on KVAR base, If we have not use external capacitor CT we can put all rated

capacitor bank KAR steps Value Manually.

5) KVAR TUNE :

This parameter is indicated auto sensing rated capacitor KVAR for each capacitor bank. We have to Mandatary used

external capacitor CT. After Completed tuning automatically switching RUN mode.

You Can Manually enter capacitor bank kvar value for each step. (Range: 000.0 to 100.0)
