Allowable Range Of Rotation Angle Of Feedback Shaft - GE FVP110 Maintenance Manual

Installing FVP110 on
Figure 23 Allowable Range of Rotation Angle of Feedback Shaft
1. Attach the bracket to the FVP110 using the four M8 bolts provided (See "Part
Names" on page 33). The installation method is determined by the combination of
the control valve and positioner, as well as by the valve manufacturer who performs
the adjustment. For details, consult the control valve manufacturer.
2. Attach the feedback lever by:
a. Ensuring that the stopper located on the side of the FVP110 to prevent an
over-rotation of the shaft (Figure 24) is attached to the feedback shaft.
3. Instal the lever, ensuring you install it on the stopper and fix the lock screw.
4. Attach the FVP110 to actuator with the bracket by (Figure 25):
a. Carefully positioning the bracket to the actuator so that the center of the rotation
axis of the valve plug and the FVP110 positioner's feedback shaft are aligned
Attaching the lever in the wrong orientation causes the
CAUTION
feedback shaft to rotate at an angle exceeding its
mechanical limits of ±55°, resulting in the FVP110 being
seriously damaged.
