Once back in AUTO Mode, the RVC automatically switches on the necessary steps to reach the programmed target
cos ϕ.
The actual cos ϕ appears on the LCD display.
Note: a negative cos ϕ indicates that the load is re-injecting reactive power on the network. The RVC continues to
work normally.
For RVT, please refer to RVT manual provided within the capacitor bank.
