Tech Tip
Reversing Positioner
We regularly receive calls from customers asking us how to reverse the action of the positioner. Follow the simple three-step process below to achieve reversing the action on your positioner.
For this Tech Tip, the positioner was originally set to 4mA closed and 20mA.

Step 1: Swap tubing of C+ and C- ports. 
Step 2: Change the Cam Configuration: Remove cover and loosen cam nut. Take cam out and flip it to the opposite side. Place cam back in the positioner making sure it is on the correct lobe. Do not tighten cam nut.
Step 3: Stroke Actuator to 4mA Position: 1) Apply supply air to the positioner. At 4mA input all the supply is directed out of the C- port to the actuator.  2) Tighten the cam nut. 3) The positioner is now set to operate from 4mA open to 20mA closed.
