Open Stop Adjustment
When a valve's open stop is a few percent more than the rated trave, correct it by:
1. Perform Auto or Manual Stop Limits.
2. Close the Calibration dialog box.
3. Change the mode to Manual Operating.
4. Move the valve until the mechanical stem travel indicator reads 100% open. The
positioner's Actual Position appears on the Main screen.
5. Open the Calibration Range dialog box.
6. Select Open Stop Adjustment to open the edit box.
7. Enter the noted position.
8. Select the GO button. The positioner exhausts air from the actuator and then fills it to
determine the mechanical stop to stop travel. The positioner multiplies the
stop-to-stop travel by the factor entered in the Open Stop Adjustment text box to
establish the position that corresponds to 100% of the adjusted travel.
