SETTINGS
Rotate the knobs to the appropriate setting for the application following the guidelines below. Do
not
apply excessive force when adjusting settings.
L ine Voltage
Rotate the VOLT ADJ. (VAC) knob to the nominal 3-phase line voltage feeding the motor to be
protected.
R estart Delay
Rotate the RESTART (SEC) knob to the desired position. The restart delay is the time between the
MotorSaver® measuring acceptable voltage and 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 between 10 and
20 seconds.
T rip Delay
Rotate the TRIP DELAY (SEC) knob to the desired setting. This setting does not affect the trip delay
on single-phasing faults (See SPECIFICATIONS Table). Typically, the trip delay is set between 1 and
5 seconds. In areas where voltage fluctuations are frequent, the trip delay may be set greater than 10
seconds.
V oltage Unbalance
Rotate the UNBALANCE TRIP (NEMA%) knob to the desired unbalance trip level. The NEMA MG1
standard does not recommend operating a motor above 1% voltage unbalance without derating the
motor. The NEMA MG1 standard also recommends against operating a motor above a 5% voltage
unbalance under any circumstances. SymCom recommends consulting the motor manufacturer for
specific tolerances.
