Phase & Motor Rotation Tester Model PMR-1
WARNING:
If the Red clockwise or counter-clockwise LED
is lit before rotating the motor shaft, it means there is voltage
present. Stop the test, disconnect the test leads and turn off the
external power.
If the clockwise red LED turns on when rotating the motor
shaft in the clockwise direction, it means the 3-phase motor
connection to the power source is in the A-B-C sequence and
the 3-phase motor should rotate clockwise when powered.
3. Rotate the motor shaft counter-clockwise. If the counter-clock-
wise red LED turns on, it means the 3-phase motor connection
to the power source is in the A-B-C sequence and the 3-phase
motor should rotate clockwise when powered.
4. If you require the motor to rotate counter-clockwise, change
the power source connections to a B-A-C sequence. The
motor should then rotate counter-clockwise when powered.
