INSTALLATION INSTRUCTIONS

FOR SYMCOM’S MOTORSAVER



MODEL 460

The Model 460 MotorSaver



is an auto ranging voltage monitor designed to

protect three-phase motors regardless of size. The MotorSaver



is used on

190-480 VAC, 50 to 60 Hz motors to protect from damage caused by single

phasing, low voltage, high voltage, phase reversal, and voltage unbalance.

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, L2 and L3 on the MotorSaver’s terminal strip to the LINE SIDE

of the motor starter. (See Figure No. 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 as shown in Figure No. 1. For alarm operation, connect the

normally closed contact in series with the control circuit as shown in Figure

No. 2.

SETTINGS 1. Line voltage adjustment: Rotate the “VOLTAGE ADJ. (VAC)” to the nominal three-phase line voltage feeding the motor 208 220 416 440 230 to be protected. 200 400 460 2. Restart delay adjustment: Rotate the 190 240 380 480 “RESTART (SEC)” adjustment to the desired position. The restart delay is the time between MotorSaver seeing MODEL 460 acceptable voltage and the MotorSaver closing its output contacts.
PAGE 4
POWER-UP Turn on the 3∅ 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.
PAGE 5
TROUBLESHOOTING SYMPTOM No lights are on. The unit seems completely dead. Red light is blinking (on initial power up). Red light is blinking (after the motor has been previously running). Red light is blinking in this pattern. Red light is on steady. LIGHT PATTERN SOLUTION N/A Measure the three line-to-line voltages. If any of the voltages are below 150 VAC, the MotorSaver does not have enough power to operate its internal electronics. This may occur on a single-phased system.
