6. Insert connection pin into the feedback lever. The pin should be inserted when the
actuator clamp is at 50% of the total valve stroke.
7. Check if the feedback lever is parallel to the ground at 50% of the
valve stroke. If it is not parallel, adjust the bracket or feedback link
bar to make parallel. Improper installation may cause poor
linearity.
8. Check the valve stroke. The stroke marks are indicated on the feedback lever.
Position the connection pin at the number on the feedback lever which corresponds to
the desired valve stroke. To adjust, mover the bracket or the connection pin or both.
9. After installing the SPTM-5v, operate the valve from 0% to
100% stroke by using direct air to the actuator. On both 0%
and 100%, the feedback lever should not touch the lever
stopper, which is located on the backside of SPTM-5V. If the
feedback lever touches the stopper, SPTM-5V should be
installed further away from the yoke.
