Technical Documentation

Operation:

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. Any one of five fault conditions will de-energize the relay after a delay. As standard, re-energization is automatic upon correction of the fault condition. Manual reset is available if an external momentary N.C. switch is connected to terminals 4 and 5. A bi-color status LED indicates normal condition and also provides specific fault indication to simplify troubleshooting (see right).
