The MVP will monitor line voltages from 200 up to 480VAC, 3Ø and automatically selects the correct operating range. Based on the adjustable settings, the output contacts will be energize when: 1. All phases are present 2. The voltages are within the adjustment parameters 3. The phases are in proper rotation. If any of these conditions are not satisfied, the output relay will drop out after the drop out time delay. There is an adjustabel re-start time delay for staggered starting. The MVP has a built-in manual reset feature with a reset button on the top.
