Note
Do not use the large number on the display to determine mid
-travel position, use the
mechanical indicator on the actuator.
● Once at the mid-travel position, release push-buttons.
● Adjust slip clutch, until number in display is within a range of: 48-52.
Figure A-1 Slip Clutch
● Move valve by pressing button only until it reaches actuator's end-stop, and verify if:
– Numerical value goes through zero, for example:
○ Number increments from: 98, 99, 100, ---, 0, 1, 2, or
○ Number decrements from: 3, 2, 1, 0, ---, 100, 99, 98
– If numerical value goes through zero then check slide bar setting and slide bar locking
mechanism, see Transmission Ratio/Slide Bar (see Appendix A). If adjustment was
made to the slide bar, repeat previous step.
● For linear applications, it is possible slide bar is set correctly but feedback pin is too close
to positioner’s input shaft. Therefore secure feedback pin further away from positioner’s
input shaft.
Adjust Potentiometer
● Using the above push button procedure to move valve, move the valve to the mid-travel
position.
Note
Do not use the large number on the display to determine mid
-travel position, use the
mechanical indicator on the actu
ator.
● Once at the mid-travel position, release the push-buttons.
