Operation

The PVC’s output contacts energize when:

1. All the phases are present;

2. The voltages are within 10% of the setting;

3. The phases are in the proper rotation

4. The phases are balanced;

5. The frequency is within tolerance.  Built into the PVC series is a 5 second pick-up delay to allow the three phase line to stabilize. If any of these conditions shift beyond the setpoints, the output contact will de-energize after a 5 second time delay.  Single phase conditions will be detected when the voltage in one phase is 5% different from the voltages in the other two phases (Phase Imbalance).
