Model 201-SP is a plug-in voltage monitor designed to protect single phase
motors regardless of size. It can be used on 95-120 VAC (201-100-SP),
190-240 VAC (201-200-SP), or 380-480 VAC (201-400-SP) motors to pre-
vent damage caused by low voltage or high voltage (optional).
The unique microcontroller-based voltage and phase sensing circuit
constantly monitors the voltage to detect harmful power line conditions.
When a harmful condition is detected, the MotorSaver's output relay is
deactivated after a specified trip delay. The output relay reactivates after
power line conditions return to an acceptable level for a specified amount
of time (RESTART DELAY). The trip delay prevents nuisance tripping due
to rapidly fluctuating power line conditions.

INSTALLATION INSTRUCTIONS FOR SYMCOM’S
MOTORSAVER®MODELS 201-SP, 201-SP-T, 201-SP-T01
BE SURE POWER IS DISCONNECTED PRIOR TO INSTALLATION!!
FOLLOW NATIONAL, STATE AND LOCAL CODES!
SETTINGS
1. LINE VOLTAGE ADJUSTMENT: Rotate the LINE VOLTAGE ADJUSTMENT to the nominal line voltage feeding the motor to be protected.
POWER-UP
Turn on the power to the motor. The MotorSaver then goes through it's restart delay and the LED will flash green. After the RESTART DELAY, the
MotorSaver ®will energize its output contacts and the RUN LIGHT will turn solid green. If the contacts do not energize and the RUN LIGHT does not
turn solid green, then see the TROUBLESHOOTING section.
Congratulations!!! You have just installed the finest motor protection available!
TROUBLESHOOTING
If the output relay does not energize and the RUN LIGHT does not turn solid green after waiting for the RESTART DELAY time, then:
1. Measure the line-to-line voltage. If the voltage is 10% above (for units with optional high voltage protection) or 10% below the voltage adjust set point,
the MotorSaver is functioning properly, saving your motor from abnormal power conditions.
2. If the unit seems to be malfunctioning, then contact SymCom at 1-800-843-8848 OR 1-605-348-5580 and we will be happy to help you.
To control a motor: Connect the normally open contact in series with the magnetic coil of the motor starter as shown for each model.
Figure No. 1:Typical Wiring Diagram
CONNECTIONS
1. Mount the MotorSaver in a convenient location in or near the motor control panel. If the location is wet or dusty, then the MotorSaver
should be mounted in a NEMA 4 or 12 enclosure.
2. Connect the lines of the power supply to L1 and L2 on the MotorSaver’s octal socket (see Figure No. 1).
3. Connect the output relay to the circuitry to be controlled (see Figure No. 1).
For motor control, use the ‘C’ and the ‘NO’ terminals.
For alarm circuits, use the ‘C’ and the ‘NC’ terminals.
