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.

Measure the three line-to-line voltages. If
any of the voltages are below 150 VAC, the

may occur on a single-phased system. If
the voltages are correct, call SymCom at
1-800-843-8848 or 1-605-348-5580.
Turn off the three-phase power. Swap any
two leads powering the MotorSaver

connecting L1, L2, and L3 correctly the fi rst
time. Re-apply the three-phase power.
The incoming lines have been reverse

the phase sequence.
The voltage is unbalanced or
single-phased. Measure the incoming line
voltages and calculate the % unbalance. If
the voltage unbalance does not exceed the
% unbalance reset value, call SymCom at
1-800-843-8848 or 1-605-348-5580.
The voltage is out of tolerance. Measure
the three line-to-line voltages. Calculate
the average of the three voltages. If the
average is 7% above or below the nominal
voltage as selected by the LINE VOLTAGE
ADJUST, the MotorSaver

selected line voltage, call SymCom at
1-800-843-8848 or 1-605-348-5580.
