Description of Function
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 pins 6 and 7. A bi-color status LED indicates normal condition and also provides specific fault indication to simplify troubleshooting (see right).
Product Overview
Features:
Protects against phase loss, phase reversal, phase unbalance, undervoltage, overvoltage & rapid cycling
True RMS voltage measurement ensures accurate sensing across more applications
Retains fault indication and continues monitoring all voltages even with a lost phase
Ultimate three-phase protection with a variety of user-selectable and adjustable settings
Full fault indication on top of unit for easy troubleshooting
Manual reset option works with external switch to reset the relay from outside the enclosure

Reset: As standard, the PMP Series relays are in the Automatic Reset mode. However, they can be set in the Manual Reset mode by connecting an external N.C. switch across terminals 6 and 7. Upon application of line voltage, the PMP Series will go into Manual Reset mode if it recognizes a closure across terminals 6 and 7. After a fault clears, the relay will not reset until the N.C. switch is opened.
