Document Outline
- Application
- DuraDrive ™ Direct Coupled Actuators are designed to be used in both damper and valve control applications. The follow general instructions are for damper applications, refer to the Applicable Literature table for valve literature.
- The MA40-704X, MA4X-707X and MA4X-715X series spring return actuators are used for the on-off, fail safe control of dampers and valves in HVAC systems.

- Rotation Limitation for MA40-704X 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. 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 MA4X-715X and MA4X-707X 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. Re-adjust if necessary.
