INSTALLATION INSTRUCTIONS

FOR SYMCOM’S MOTORSAVER



MODEL 460-SP

The Model 460-SP MotorSaver is a voltage monitor designed to protect
single-phase motors regardless of size. The MotorSaver



is used on 190­240 (95-120) VAC, 50 to 60 Hz motors to protect from damage caused by low
voltage and high voltage.

CONNECTIONS

1. Mount the MotorSaver in a convenient location in or near the motor

control panel. If the location is wet or dusty, the MotorSaver should
be mounted in a NEMA 4 or 12 enclosure. The MotorSaver can be
mounted to a back panel using two #6 or #8 x 5/8 screws or can be
snapped onto a DIN rail.

2. Connect L1 and L2 on the MotorSaver’s terminal strip to the LINE SIDE

of the motor starter (See Figure 1).

3. Connect the output relay to the circuitry to be controlled. For motor control,

connect the normally open contact in series with the magnetic coil of the
motor starter (See Figure 1). For alarm operation, connect the
normally closed contact in series with the control circuit (See Figure 2).

SETTINGS

1. Line voltage adjustment: Rotate the “VOLTAGE ADJ. (VAC)” to the nominal
line voltage feeding the motor to be protected.

2. Restart delay adjustment: Rotate the “RESTART (SEC)” adjustment to the
desired position. The restart delay is the time between the MotorSaver®
seeing acceptable voltage 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 between
2 and 10 seconds.

CONGRATULATIONS!!

YOU HAVE JUST INSTALLED THE FINEST

MOTOR PROTECTION AVAILABLE!!

POWER-UP

Turn on the power to the motor. The MotorSaver’s 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 illuminate. If the
contacts do not energize and the RUN light does not illuminate, see the
TROUBLESHOOTING section.

TROUBLESHOOTING

SYMPTOM

LIGHT

PATTERN

SOLUTION

No lights are on.

The unit seems

completely dead.

N / A

Measure the voltage. If the voltage is below
75 VAC, the MotorSaver



does not have
enough power to operate its internal elec­tronics.
If the voltage is correct, call SymCom at
1-800-843-8848 or 1-605-348-5580.

Red light is on

steady.

The voltage is out of tolerance. Measure
the input voltage. If the voltage is 7% above
or below the nominal voltage as selected
by the LINE VOLTAGE ADJUST, the
MotorSaver



is functioning properly. If the
voltage is within ±7% of the selected line
voltage, call SymCom at
1-800-843-8848 or 1-605-348-5580.

Green light blinks

and motor is not

running.

The MotorSaver



is in restart delay.

Green light is on

steady, but motor

does not start.

The MotorSaver



is in run mode. Ensure
other control devices are allowing the
motor to start. Check control circuit for
loose wires or malfunctioning switches.
