Smart Positioner YT-2700L,R Installation manual
3) Attach YT-2700L (with bracket) to the actuator yoke – DO NOT TIGHTEN COMPLETELY.
4) Connect YT-2700L feedback lever to the actuator clamp. The gap on the YT-2700L
feedback lever is 6.5mm. The connection bar thickness should be less than 6.3mm.

5) Connect air filter regulator to the actuator temporarily. Set supply pressure of the regulator in
order to position the actuator clamp at 50% of valve stroke. <Figure 4>
6) Insert connection bar into the YT-2700L feedback lever. The connection bar should be
inserted at the 50% point on the feedback lever, which would help to reduce hysteresis.
7) If connection bar does not point at 50% point, then adjust bracket or feedback link bar
position. Failure to position at 50% would lower the linearity of the poistioner. <figure5>
