6.2.1 Three-Phase Motor
NOTE: Your application may vary from the standard wiring configuration for three-phase shown in
Figures 6.1 and 6.2. Refer to the specific actuator wiring diagram for wiring configuration.
1. Using the Handwheel, move the valve to a midtravel position. Midtravel position allows brief
electrical operation in the valve “safe” area and keeps the OPEN and CLOSED Limit Switches from
tripping while testing motor direction.
2. Test motor direction by momentarily pressing the OPEN pushbutton:
a. If the actuator moves toward CLOSED, immediately turn all power OFF and reverse the
motor leads T1 and T3 on terminal strip.
b. If the actuator moves toward OPEN, the motor is wired properly for the application.
