Operations

Phase Loss: Unit trips on loss of any Phase L1, L2 or L3, regardless of any regenerative voltages. Phase Reversal (Out-of-Sequence): Unit trips if sequence (rotation) of the three phases is anything other than L1-L2-L3. It will not work on L3-L2-L1. Phase Unbalance: Adjustable from 5 – 25% unbalance or can be disabled. Unit trips when any one of the three lines deviates from the average of all three lines by more than the adjusted set point for a period longer than the adjustable trip delay.
