When the proper 3-phase line voltage is applied to the unit and the phase sequence (rotation) is correct, the relay is energized. A phase loss or phase reversal condition will de-energize the relay after a delay. Re-energization is automatic upon correction of the fault condition. A bi-color status LED indicates normal condition and also provides specific fault indication to simplify troubleshooting (see right).
