7. Inspect actuator for proper lubrication. Refer to “Lubrication” Section 6.1 for lubrication instructions.
8. Verify that Motor rotation is operating in the proper direction; the Motor rotation will have a direct impact on the Limit Switch and
Torque Switch functions. Follow the procedure “Verifying Motor Rotation Direction” in Sections 4.4.2, 4.4.3 and 4.4.4).
9. Close Electrical Compartment Cover (piece 200-1).
10. The actuator is now ready for electrical operation. Continue to “Electrical Start-up Procedure” in Section 5.3.
4.2.2 Motor rotation (phasing) and OPEN/CLOSE Pushbutton Operation
It is very important to check for correct motor rotation to ensure that serious damage to your valve or other equipment does not occur. If
the actuator motor rotates in the wrong direction, damage could occur by over-torquing equipment into a seated position.
Prior to being shipped from the factory, each actuator is inspected to verify proper operation of the Torque and position Limit Switch and
to ensure that they function correctly (i.e. closes when the CLOSE pushbutton is depressed, opens with the OPEN pushbutton, etc.). These
inspections are made with a properly phased power source connected as described in the actuator manual.
a
CAUTION:
To ensure proper operation and to prevent your actuator or other actuated equipment from damage, verify that your actuator
is properly connected to its power source.
NOTE:
Your application may vary from the following standard wiring configurations for Three-phase, Single-phase and DC motors.
Refer to your actuator wiring diagram for user-specific wiring configuration.
4.2.3 Three-Phase Motor
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. Be prepared to immediately remove power should the actuator run the wrong way.
3. 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.
NOTE:
Refer to your actuator wiring diagram for user-specific wiring configuration.
B) If the actuator moves toward OPEN, the motor is wired properly for the application.
4.2.4 DC Motor
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. Test the 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 A1 and A2.
NOTE:
Refer to your actuator wiring diagram for user specific wiring configuration.
B) If the actuator moves toward OPEN, the motor is wired properly for the application.
