Its circuit design separately senses Phase Reversal, Undervoltage, and Voltage Unbalance including Phase Loss. Protection is assured during periods of large average voltage fluctuations, or when regenerated voltages are present. Both Delta and Wye systems can be monitored; no connection to neutral is required. Operation Operation Field Adjustment: Field Adjustment: Operation Operation Operation Field Adjustment: Field Adjustment: Field Adjustment: ANSI Device #47/27 The output relay is energized and the LED glows when Set voltage, trip delay, and voltage unbalance all voltages are acceptable and the phase sequence percentage (consult equipment manufacturer's is correct. Undervoltage and voltage unbalance must specifications). Make connection to all three line be sensed for a continuous trip delay period before phases as shown in the connection diagram. Protects Against: Phase the relay and the LED are de-energized. Re- Apply power. If the relay fails to energize, check Loss, Phase Reversal, energization is automatic upon correction of the fault the wiring of all 3 phases, voltage, and phase Undervoltage & condition. The output relay will not energize if a fault sequence. If phase sequence is incorrect, swap Unbalance Voltages condition is sensed as power is applied. any two wires.
