Mounting Using Direct Coupling (Typical)Due to the wide range of applications that the Type AV positioneris suited for, we can only provide general information aboutmounting. Use the following procedure to mount the positioner.WARNINGBefore mounting or installing positioner, check nameplatedata to make certain positioner is suitable for applicationdesired. DO NOT AT ANY TIME EXCEED THE RATINGSLISTED ON THE NAMEPLATE.1. Set the actuator at the zero position. Connect the adjustablelinkage to the drive arm. The drive arm holes correspond to strokelength of the actuator. Refer to Figure 3-3 for the stroke length foreach drive arm hole.2. Install the cam (black, direct acting; or red, reverse acting) thatwill provide the required direction of rotation.A direct acting (black) positioning cam with segments A, B and C(Fig. 3-7) and a reverse acting cam are furnished with each positioner.The reverse acting cam has red radial lines and arcs andis stored on the inside of the positioner cover. Cam A is for asquare root function, cam B is for linear motion and cam C is for aMOUNTING TYPE AV POSITIONERS3 - 6
INSTALLATIONsquare function (Table 3-1). Cam B is in place when the positioneris shipped from the factory. The cams may be shaped to conformto special applications. Refer to Appendix C for information aboutcam shaping.NOTE: If the application is reverse acting, the reverse actingcam (red radial lines) must be installed and the connections toports 01 and 02 must be reversed.RADIALLINESCONCENTRICARCS45° CAMAV??1????90° CAMAV??2????T00805AFigure 3-7.

Cammotion is 90 degrees (Type AV__2____) or 45 degrees (TypeAV__1____) depending on the positioner type specified bynomenclature (Figure 3-7).Each cam shape (A, B or C) has its own eight-point center hole formounting on the camshaft (Fig. 3-7). Place the cam in one of theeight 45-degree positions so that the midpoint of the cam correspondsto the mid stroke of the actuator. The drive arm should beperpendicular to the motion of the actuator with the actuator at midstroke.3. Adjust the connecting linkage so that the zero radial line onthe cam intersects the center of the cam roller when the actuatoris at its zero position (Fig. 3-8).MOUNTING TYPE AV POSITIONERS3 - 7
