1.08 DESCRIPTION OF BASIC MENU PARAMETERS
P.01 - CT primary current
For values higher than 1000, a flashing dot indicates "thousands".
P.02 - Smallest step kvar
Rated power in kvar of the smallest installed capacitor bank.
Example: For 10 kvar, set 10.0
P.03 - Rated capacitor voltage
Rated voltage (nameplate) of the capacitors.
Example: For 460V, set 460
P.04 - Reconnection time of the same step in seconds
Minimum time needed for the capacitor to discharge and be ready to be used again.
Example: For 60 seconds, set 060
P.05 - Sensitivity
The sensitivity is a coefficient, which allows adjusting the controller operating speed. A
low sensitivity provides faster adjustments but with a greater number of switchings. With
high sensitivity, the regulation is slower but with fewer switchings.
The sensitivity value corresponds to the time the controller waits before responding to a
