6.2.2 Single-Phase Motor
NOTE: Your application may vary from the standard wiring configuration for the single-phase motor
shown in Figures 6.3 and 6.4. Refer to the specific actuator wiring diagram for wiring configuration.
1. Using the Handwheel, move the valve to a midtravel position. Midtravel position allows electrical
operation in the valve “safe” area and keeps the OPEN and CLOSED limit switches from tripping
while testing motor direction.
2. Momentarily press the OPEN pushbutton to test motor direction. If the actuator moves toward
CLOSED, immediately turn power OFF and proceed with the instructions that match your applica-
tion. Permanent Split Capacitor single-phase motors can be connected for opposite rotation by
interchanging the leads T1 and T2 coming from the motor to the terminal strip.
