NOTE: If your actuator is equipped with a Type AV positioner as
ordered, verify that all the connections are secure and make any
adjustments as required.
Use the following procedure for mounting guidelines.
1. Set the actuator at the 0 position. Connect the adjustable link-
age to the drive arm. The drive arm holes correspond to stroke
length of the actuator. Refer to Figure
each drive 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, lin-
ear; 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).
