SETTINGS

1. LINE VOLTAGE ADJUSTMENT: Rotate the LINE VOLTAGE
ADJUSTMENT to the nominal three-phase line voltage
feeding the motor to be protected. The Model 460L will
automatically sense whether it is connected to a 200V or
400V 60 Hz or 380V - 416V 50Hz power system.

2. RESTART delay: Rotate the RESTART delay to the
desired position. The restart delay is the time between the

MOTORSAVER

®

seeing acceptable power and the

MOTORSAVER

®

closing its output contacts. For compressor
applications, the restart delay should be set for the
approximate time it takes for the head pressure to bleed
off of the compressor. For other applications, the restart
delay is typically set at 2 seconds.

POWER-UP

Turn on the power to the motor. The green RUN LIGHT will blink during the RESTART delay.
After the RESTART delay, the MOTORSAVER

®

will energize its output contacts and the green RUN
LIGHT will light. If the contacts do not energize and the RUN LIGHT does not light, then see the
TROUBLESHOOTING section.
