The overcurrent alarm is triggered when sampling current is bigger than
6.0A.
The switching lock-up time for the same group of capacitors is 3 minutes.
Provides circular self-test function for factory testing of capacitor screen.

Current ratio setup range for external sampling current transformer: 5~1200, set ratio
(factory preset 60 means 300/5)
5~120 seconds (factory preset 30 seconds)
Full automatic mode (display code 1): no need to set adding threshold and removing
threshold.
Manual setup mode(display code 0): adding threshold and removing threshold need
to be set manually.
Full automatic mode: capacity of the smallest capacitor bank
Manual mode: reactive set value, 1~120kvar(factory preset 10 kvar)
Power factor, 0.85~-0.95 continuously adjustable (factory preset 1.00)
