6. Insert connection bar into the YT-1000L feedback

lever. The connection bar should be inserted at the

50% point on the feedback lever, which would help to

reduce hysteresis.

(Figure 5)

7. If the connection bar does not point at the 50%

point, then adjust the bracket or feedback link bar

position. Failure to position at 50% would lower the

linearity of the positioner.

NOTE: After installing the YT-1000L, operate the valve

from 0% to 100% stroke by using the air filter regulator

on the actuator. Both at 0% and 100%, the feedback

lever should not touch the lever stopper, which is

located on the backsideof the YT-1000L.

(Figure 8)

If the feedback lever touches the lever stopper,

YT-1000L should be installed further away from the

center of the yoke.

9. After the proper installation, tighten all the bolts on

the bracket, the feedback lever, and the connection

bar.
