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).

Application Information

• Load (Burden): Less than 40 VA

• Response Times:

  Power Up/Restart After Fault: Fixed at 2 Seconds
  Drop-out Due to:   Phase Loss & Reversal   Phase Unbalance   Undervoltage   Overvoltage	100ms Fixed Fixed 4 Seconds Fixed 4 Seconds Fixed 4 Seconds

• Minimum/Maximum Voltage: 156V Minimum / 550V Maximum1, 50/60Hz. +5%

• 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.
