NOTES:
1. High temperature Type AV1 positioners are only available without manifolds or position transmitters; however, gage blocks are permitted.
2. Explosionproof Type AV2 positioners are not available with position transmitters or manifolds.
3. No longer available as of October 2003.

Install the positioner as required on the actuator. Figures
B-2 show typical mounting arrangements. Use the following pro-
cedure for mounting guidelines.
NOTE: If the actuator is equipped with a Type AV positioner as
ordered, verify that all the connections are secure and make any
adjustments as required.
1. Set the actuator at the zero position. Connect the adjustable link-
age to the drive arm. The drive arm holes correspond to stroke length
of the actuator. Refer to Figure
arm hole.
2. Install the cam (black, direct acting; or red, reverse acting) that
will provide the required direction of rotation.
NOTE: Cams have three mounting holes: A, square root; B, linear;
C, square. Each mounting hole is star shaped so the cam can be
rotated in 45° increments to suit the application.
3. With the actuator in the closed position, adjust the connecting
linkage so that the zero radial line on the cam intersects the center of
the cam roller (Fig. B-4).
4. Lock all linkage components in place.
