When the proper 3-phase line voltage is applied to the unit and the phase sequence (rotation) is correct, the relay is energized after the Restart Delay is completed. An out-of-sequence condition will prevent the relay from energizing on start-up or de-energize the relay if it occurs when it is energized. Re-energization is automatic upon correction of the fault condition. A bi-color status LED indicates both a normal condition with the proper phase sequence (solid GREEN) or a fault condition with the phases out of sequence (solid RED).
