Mount Actuator onto Damper Shaft (PVL0000AS, PVL4022AS, and PVL6436AS) PVL0000AS, PVL4022AS, and PVL6436AS controllers include the direct-coupled actuator with Declutch mechanism, which is shipped hard-wired to the controller. The actuator mounts directly onto the VAV box damper shaft and has up to 44 lb-in. (5 Nm) torque, 90-degree stroke, and 90 second timing at 60 Hz. The actuator is suitable for mounting onto a 3/8 to 1/2 in. (10 to 13 mm) square or round VAV box damper shaft. The minimum VAV box damper shaft length is 1- 9/16 in. (40 mm). The two mechanical end-limit set screws control the amount of rotation from 12° to 95°. These set screws must be securely fastened in place. To ensure tight closing of the damper, the shaft adapter has a total rotation stroke of 95° (see Fig. 1). NOTES: 1. The actuator is shipped with the mechanical end limit set screws set to 95 degrees of rotation. Adjust the two set screws closer together to reduce the rotation travel. Each “hash mark” indicator on the bracket represents approximately 6.5° of rotation per side. 2. The Declutch button, when pressed, allows you to rotate the universal shaft adapter
