INSTALLATION INSTRUCTIONS FOR SYMCOM’S

MOTORSAVER®MODEL 202-200-SP-NHV

BE SURE POWER IS DISCONNECTED PRIOR TO INSTALLATION!!

FOLLOW NATIONAL, STATE AND LOCAL CODES!

CONNECTIONS

1. Mount the MotorSaver®in a convenient location in or near the motor control panel using a 1/4” socket head cap screw (customer supplied). If
the location is wet or dusty, the MotorSaver®should be mounted in a NEMA4 or 12 enclosure.

2. Connect the two lines of the motor’s single-phase power supply to L1 and L2 using insulated 1/4” female, ULrecognized quick connectors.

3. Connect the output relay to the circuitry to be controlled using insulated 1/4” female , UL recognized quick connectors.

(A) To co ntrol a motor: Connect the normally open contact in series
with the magnetic coil of the motor starter as shown.

(B) To so und an alarm: Connect the normally closed conta ct in series

with the alarm as shown.

SETTINGS

1. LINE VOLTAGE ADJUSTMENT: Rotate the LINE VOLTAGEADJUSTMENTto the nominal single-phase line voltage feeding the motor to be protected.

2. TIME DELAY RESTART: 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 othe r application s, the restart delay is typically set to 2 seconds. If the
RESTART DELAY is in the manual (MAN) position, the unit will not restart until it is turned out of the manual position.

Setting multiple units at staggered restart delays will enable sequential starting after a complete power loss.

POWER-UP

Turn on the power to the motor. During the restart delay the STATUS LIGHT will flash green. After the RESTART DELAY, the MotorSaver®will
energize its output contacts and the STATUS LIGHT will turn solid green. If the contacts do not energize and the STATUS LIGHT does not turn
solid green, see theTROUBLESHOOTING section.

TROUBLESHOOTING

If the output relay does not energize and the STATUS LIGHT does not turn solid
green after waiting for the RESTART DELAY time:

1. If the STATUS LIGHT turns solid red, upon applying power, the Model 202
may be in the manual reset mode. Rotate the RESTAR DELAY knob
clockwise 1/8 turn, above "2." If thelight does not flash green, proceed to
step 2.

2. If the MotorSaver® still seems to be malfunctioning and the STATUS
LIGHT is solid red, measure the single-phase voltage. If the voltage is lower than 93% of the Line Voltage Adjustment setpoint, the MotorSaver®is
functioning properly—a low voltage condition is present.

3. If the voltage is above 93% of the Line Voltage Adjustment, contact SymCom at 1-800-843-8848 or 1-605-348-5580, we will be happy to help you.
