- Rotation Limitation for MS40-7043 Series
- 1. Determine the amount of damper rotation required. The actuator stop block provides limited rotation from 40˚ to 95˚.
- 2. Loosen the screw securing the stop block to the actuator.
- 3. Slide the stop block into position, so that its edge lines up with the degree graduation on the actuator face which corresponds with the required rotation. See Figure-5.
- 4. Secure the stop block in place.
- 5. Test the damper rotation by applying power and the required control signal. Re-adjust if necessary.
- Figure-5 Adjusting Stop Block for Limited Rotation.
- 1. Determine the amount of damper rotation required. The actuator stop block provides limited rotation from 40˚ to 95˚.
- Rotation Limitation for MS4X-7153 and MS4X-7073 Series
- 1. Determine the amount of damper rotation required.
- 2. Locate the AM-689 rotation limiter on the actuator so that its edge lines up with the degree graduation on the actuator face which corresponds with the required rotation. See Figure-6.
- 3. Find the appropriate cross-hair location through the slot of the rotation limiter. This is the mounting location for the retaining screw.
- 4. Pierce through the label material to allow easy fastening of the retaining screw.
- 5. Position the rotation limiter back to the desired position, making sure the locating “teeth” on the rotation limiter are engaged into the locating holes on the actuator.
- 6. Fasten the rotation limiter to the actuator using the self-tapping screw provided.
- 7. Test the damper rotation by applying power and the required control signal. Re-adjust if necessary.
- Figure-6 Securing the AM-689 Rotation Limiter.
- 1. Determine the amount of damper rotation required.
- Minimum Damper Positioning
- 1. Position the damper to its minimum position by providing the appropriate control signal to the MS4X-7073 or MS4X-7153.
- 2. Place the position indicator onto the actuator spline in the approximate position shown in Figure-7. Fasten it with the retaining clip.
- 3. Place the AM-689 rotation limiter on the actuator so that it either makes contact with, or is as close as possible to, the edge of the indicator. See Figure-8.
- 4. Make sure that the locating teeth are engaged into the locating holes on the actuator. If all of the mounting teeth do not al...
