5. Attach the FVP110 to the actuator with the bracket using the specified bolts.
The linkage between the FVP110 positioner and control valve’s stem via the clamp
and lever and the adjustment of this linkage is a decisive factor for determining the
characteristics of the control valve combined with the FVP110 positioner.
6. Insert the FVP110’s feedback shaft into the small hole on the stopper side of the lever
(Figure 19).
CAUTION Attaching the lever in the wrong orientation causes the
feedback shaft to rotate at an angle exceeding its mechanical
limits of ±55 °, resulting in the FVP110 being seriously
damaged.
A stopper is attached to the feedback shaft to prevent an over-rotation of the shaft
(Figure 19).

7. Install the lever, ensuring you install it on the stopper and fix the lock screw
(Figure 20).
