d. Depress the Green "I" start button then the Red "O" stop buttons. This
will quickly cycle the pump motor.
e. Remove the shaft cover plug to observe the motor shaft. When the unit
is on, the motor shaft will rotate. When switched off, the shaft will slowly
“coast” to a stop. As the shaft slows, the operator can identify the rotation
of the motor shaft.
Correct rotation (correct phase) is “clockwise”, when viewed from
the rear of the motor.
Correct shaft rotation is clockwise.
Incorrect rotation is “counter-clockwise” (incorrect phase) when viewed
from the rear of the motor.
If the shaft does not rotate when the unit is switched on, the operator
must identify the cause as outlined in the troubleshooting and repair
section of this manual.
f. If the motor shaft is phased correctly (shaft turns in a clockwise
direction), continue with
step C . If the motor shaft is NOT phased
correctly (shaft turns in a counter-clockwise direction), correct as outlined
in
step 2 .
2. If the unit is phased incorrectly , the operator must:
a.
Disengage the electrical power supply to the unit at the unit’s disconnect
switch. Follow all facility proper lock-out tag-out procedures before
proceeding.
b. Once the electrical power supply is disengaged the operator can change
rotation by switching any two incoming power conductors at the terminal
block or customer supplied main power disconnect.
