    • to use a longer switching delay time and as a result, to reduce the number of switchings. On the basis of the reactive power demand measured during the switching delay time, the RVC identifies the number of steps to be switched on. It then automatically switches the bigger outputs first to avoid unnecessary intermediary switchings.

Energize the PF Controller Note: If you have a short-circuit on the CT’s secondary winding AUTO do not forget to open it after having connected the current input of the PF Controller. After a power outage, the reset delay time is 40 seconds. During this delay time, the alarm icon blinks and the alarm contact remains closed.
