TIME MARK 153 Installation Instructions Manual

MODEL 153
Reverse Phase Relay
l Senses phase reversal on Wye or Delta
l 190 to 500 VAC range
l l Surface-mount Enclosure
l l Low power consumption
DESCRIPTION
The Model 153 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.
illuminate with correct A B C phase rotation.
