Commissioning Procedure - Proportional Control
After completing all mounting and wiring procedures and main power is available, it is now possible to commission
the actuator .
1. Utilize the handwheel or override shaft 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. Apply correct power to the unit.
4. Measure correct power and polarity on terminals 1 & 2 AT THE MAIN TERMINAL BLOCK.
5. Command the fi eld device to generate a 20mA (10vdc) signal. The actuator OUTPUT shaft rotates in a CCW direction
(as viewed from above) and stops at the full CCW (Open) position.
6. Measure terminals 5 (+) and 6 (-) to read 20mA (10vdc).
7. Read continuity between terminals C & D to show the CCW Aux switch is closed.
8. Command the fi eld device to generate a 4mA (2vdc) signal . The actuator OUTPUT shaft rotates in a CW direction
(as viewed from above) and stops at the full CW (Closed) position.
9. Measure terminals 5 (+) and 6 (-) to read 4mA (2vdc).
10. Read continuity between terminals A & B to show the CW Aux switch is closed.
11. Generate a 12mA (6vdc) signal at the fi eld device to move the actuator to its mid-travel position.
12. Actuator stops at 50% travel, and feedback measuers 12mA (6vdc) +/- tolerance error if any (single decimal).
13. Return Field control to automatic mode. Actuator is now commissioned and operational.
