Commissioning
After completing all mounting and wiring procedures and main power is available, it is now possible to commission
the actuator.
1. Utilize the handwheel to rotate the actuator and damper, valve or other connected device through its full travel from
full CW to full CCW and back again to check for any possible interference. Do NOT utilize any mechanical advantage
devices to rotate the handwheel (pipes, wrenches, extension bars, etc.).
2. Manually position the actuator to its mid-stroke position.
3. Make certain the 3 wire orange plug is fully seated on the 3-pin receptacle on the switch board.
4. Apply correct power to the unit.
5. Measure correct power on terminals 1 and 2 on the switch board.
6. Measure correct power on the two heater terminals on the switch board.
7. Command the field device to generate a CCW signal. The actuator rotates in a CCW direction (as viewed from above).
8. Actuator will stop when it reaches it's full CCW position.
9. Command the field device to generate a CW signal. The actuator rotates in a CW direction (as viewed from above).
10. Actuator will stop when it reaches it's full CW position.
11. Generate a mid-position signal at the field device to move the actuator off its full CW trip position.
12. Actuators with no -TS options are now commissioned and operational. See below for additional -TS steps.
Commissioning for TS units
TS units incorporate a torque overload protection system. In NORMAL
operating mode, the torque switch drive cam is in this position:
WARNING! Do NOT
adjust
the
torque
switch cam settings.
This will VOID the
warranty.

Test Torque Switch functions
1. Generate a 4mA or 20mA control signal and let the actuator
drive towards that CW or CCW position.
2. As the motor is running, simulate a torque switch event:
Depress the top or bottom torque switch and hold it (one
will immediately stop the motor).
3. Release the torque switch.
4. Test recovery from the torque switch event.

5. Repeat steps 5.A through 5.D in the opposite direction
(20mA or 4mA) to test the opposing direction torque switch
functionality.
