Reverse Phase Relay

 Senses phase reversal on Wye or Delta

 190 to 500 VAC range

 Machine tool case

 UL Recognized & CSA Certified

DESCRIPTION

The Model 2532 Reverse Phase Relay is designed to
continuously monitor phase rotation of 3-phase lines.
This device should be used in applications where proper
phase rotation is critical, such as fan motors,
compressors, grinders, elevators, etc.

The solid-state sensing circuit drives an internal
electromechanical relay which energizes when power,
with correct phase rotation, is applied.

The relay will not energize if the applied phases are
reversed. It will de-energize if phase rotation is reversed
while the motor is running. An LED indicator will
illuminate with correct ABC phase rotation.

READ ALL INSTRUCTIONS BEFORE INSTALLING, OPERATING OR SERVICING THIS DEVICE.

KEEP THIS DATA SHEET FOR FUTURE REFERENCE.

GENERAL SAFETY

POTENTIALLY HAZARDOUS VOLTAGES ARE PRESENT AT THE TERMINALS OF THE MODEL 2532.

ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING.

THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.

Installation Instructions

INSTALLATION

Mount the Model 2532 in the desired location.

Connect the 3-phase power to the terminals marked A,
B, and C.

Connect the control circuit to the terminals with the
contact markings. Refer to the Typical Application
wiring diagram for additional information.

If the relay contacts do not transfer when power is
applied (LED indicator-Off), check that all three
voltages are correct.

If power is present and the voltage is correct, remove
power. Reverse two of the three phase connections.
Re-apply power.

The contacts should transfer to the normal condition
(normally open contacts closed; LED indicator-On).
Calibrations or adjustments are not required.

TROUBLESHOOTING

Should the relay fail to operate properly, check that all
three voltages are present and are of the correct level.
Check all fuses and verify that all wiring connections are
correct. Should problems persist, contact the factory for
assistance.
