2. Turn off the 3-phase power. Swap any two leads: L1 and L2; L2 and L3; L3 and L1. You have a 50-50
chance of connecting L1, L2 and L3 up correctly the first time. Turn on the 3-phase power.
3. If the MotorSaver
®
still seems to be malfunctioning, measure the three line-to-line voltages. Calculate
the average of the voltages. If the average voltage is 10% above (high voltage protection standard on
Model 250 only) or 10% below the voltage adjust setpoint, the MotorSaver
®
is functioning properly,
saving your motor from abnormal power conditions.
4. If the average of the three line voltages is within ±10%, calculate the voltage unbalance using the
NEMA method shown below:
% voltage unbalance = (max. deviation / average of the three voltages) x 100
EXAMPLE: Find the largest deviation from the average voltage and divide it by the average for the
NEMA unbalance.
L1 - L2 = 460VAC, L2 - L3 = 466 VAC, L3 - L1 = 490 VAC
Average = (460 + 466 + 490)/3 = 472
490 is the largest deviation from the average voltage.
Max. deviation = 490 - 472 = 18
% voltage unbalance = (18/472) x 100 = 3.8%
If the percent voltage unbalance is greater than 4.5%, MotorSaver
®
is functioning properly, saving your
motor from abnormal power conditions.
5. If the percent voltage unbalance is less than 4.5%, contact SymCom at 1-800-843-8848 OR
1-605-348-5580 and we will be happy to help you.
