The Model
455
-480R, 3-phase voltage monito r combines line and load-side monitoring to alert the user of contactor failure. Line-side monito ring will protect the motor from damaging power conditions including high and low voltage, voltage unbalance, single-phasing, phase reversal and rapid cycling. The Model 455-480R has a high voltage relay to handle up to 600V control voltage and is now equip
ped
with an infrared LED to communicate with the hand-held diagnostic tool, the Informer MS
Ed
ition, t
o display trip points, real-time data, and the last 20 faults and 32 motor starts.
CON
NECTION
S
1.
Mount
the MotorSaver® in a convenient location in or near the motor control panel. If the
location is wet or dusty, it should be mounted in a NEMA 4 or 12 enclosure.
2. Connect L1, L2, and L3 on the MotorSaver® to the LINE SIDE of the motor starter.
3. Connect M1, M2 and M3 to the power lines on the LOAD SIDE of the motor starter. NOTE: If a 2-pole contactor is used, jump the hard-wired line from the L side terminal (the wire
not connected through the con tactor) to its co rresponding M terminal.
If load-side protection is not desired, connection to the M terminals is not required—the Model 455-480R will operate as a line-side only voltage monitor in this configuration.
4. Connect the output relay to the circuitry to be controlle d . Connect the normally open contact
in series with the magnetic coil of the motor starter as shown in Figure 1.
NOTE: L1 and M1 must be connected to the same supply line as shown. Similarily, L2 and M2, as well as L3 and
M3 must be connected to the same supply lines.

1. LINE
VOLTAGE
ADJUSTMENT: Rotate the
VOLT. ADJ. (VAC) knob to the nominal 3-phase line voltage feeding the motor to be protected.
2. RESTART DELAY: Rotate the RESTART (SEC) knob to the desired positio n. The restart delay is the time between the Moto rSaver seeing acceptable power and the MotorSaver closing its output contacts. For compressor applications, the restart delay should be set fo r the approximate time it takes for the head pressure to bleed off of the compressor. For o the r applica tions, the restart delay is typically set to 2 se conds. NOTE: This delay is also the minimum cycle time or rapid-cy cle time r for the motor or compresso r when control power is lost such a s the operation of the thermostat.
The manual position (MAN) on the restart adjustment can be used as a manual reset after any fault condition, or loss of incoming power. To utili ze this feature, rotate the restart adjustment to “2” to allow the run light to come on—then rotate the restart delay knob back to the manual position. NOTE: When the manual feature is used , the unit will not have rapid-cycle protection if the control power is lost (i.e. thermostat control); but will require a manual reset if any fault or loss of incoming power is experienced.
3. VOLTAGE UNBALANCE: Rotate the UNBALANCE TRIP (NEMA %) to the desi red voltage unbalance trip level. The NEMA MG1 standa rd does not recommend operating a motor above a 1% voltage unbalance as determined by the following formula without derating the motor.
% Voltage Unbalance = Maximum Deviation from the Average
x 1
00%
Average
The NEMA MG1 stan dard also recommends against operating a motor above 5% voltage unbalance under any circumstan ce s. Therefo re, a 5% UB se tting is a good place to start, but SymCom recommends con sulting the motor manufacture r for specific tolerances.
4. TRIP DELAY ADJUSTMENT: Rotate the TRIP DELAY knob to the desired setting. The adjustment does not affect the trip delay on a single-phasing fault. Typi call y , the trip delay is set to 4 seconds, in areas where voltage fluctuations are freq uent, the trip delay may need to be set higher.
POWER-UP
Tur
n on the 3-phase 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 light will illuminate. If the contacts do not energi ze and the RUN light doe s not illuminate , see the TROUBLESHOOTING section .

The RUN
li
ght does not blink on initial power-up and all three fault lights are on.
Check the RESTART DELAY. If it is set to the manual position (MAN), the Model 455 is in manual reset mode. Turn the RESTART DELAY out of MAN until the output contacts close.
N
o
LEDs are lit—the unit
seems completely dead.
Measure the three line-to-line voltages. If any of the voltages is less than 305VAC, the MotorSaver® does not have enough power to operate its internal electronics. This may occur on a single-phased system.
PHASING FAULT l
ight is

inking on initial power-up.
Turn off the 3-phase power. Swap any two leads powering the Model 455: L1, L2, or L3. There is a 50:50 chance of co rrectly connecting the leads the first time. Re-apply power.
PHASING FAULT l

previously been running.
The incoming lines have been reverse-phased. Swap any two incoming power lines to the magnetic contactor.
The PHAS
ING
FAULT light is on and the unit will not reset even though the RESTART DELAY is not in the manual (MAN) position.
Measure incoming lines for correct voltage. If the voltage s do not exceed the NEMA unbalance setting, a single-phasing condition has occurred on the load side o f the contactor. Check the contacts on the magnetic contactor. If the contacts appear in good condition, check the wiring to M1, M2 and M3. Power must be removed an d re-applied to clear this fault condition. If the contacts and wiring are good, call SymCom at (800) 843-8848.

Measure the three line-to-line voltages and calculate the av erage. If the average is outside ±7% of the nominal voltage as set by VOLT. ADJ., the MotorSaver®is functioning properly. If the voltage is within ±7% of the nominal voltage, call Sym Com at (800) 843-8848.
