PRE-INSTALLATION

Inspection

Inspect the package for damage. If damaged, notify the appropriate carrier immediately. If undamaged, open the package and inspect the device for obvious damage due to shipping. Return damaged products.

Required Installation Items

• Wiring diagrams

• Tools (not provided):

Digital volt-ohm meter (DVM) Appropriate drill and drill bit for mounting screws Appropriate wrenches for adjustment of damper and valve linkages TOOL-209, 135 ohm slidewire and 0 to 7 mA manual positioner

• Appropriate accessories

• Mounting screws or bolts (not provided)

• Wire nuts (not provided)

Mounting

The actuator can be mounted in any position in a weather protected area. It is recommended that valve actuators be mounted above the centerline of the valve body. When selecting a location, allow sufficient room for accessories and for service of the product.

MS-8301X Valve Actuators

For the correct installation of valve linkages refer to the instruction sheets for AV-430 (F-19072) or AV-495 (F-21665) which-ever is appropriate for the particular valve body.

INSTALLATION

Caution:

1. Installer must be a qualified, experienced technician.

Figure-1 Dimensions for MX-830XX Series.

2. Disconnect power supply before installation to prevent electrical shock and equipment damage.

3. Make all connections in accordance with electrical wiring diagram, and in compliance with national and local codes. Use copper conductors only.

4. Do not exceed the ratings of the device.

5. Avoid locations where excessive moisture, corrosive

Accessories typically required for mounting per Figure 3

• Crank arm for damper shaft; AM-111, AM-112, AM-113 or

AM-115

• Ball joint; AM-122 or AM-132

• Damper rod, 5/16" dia.; AM-125 or AM-125-048

fumes or vibration are present. NEMA Type 1 housings are intended for indoor use primarily to provide a degree of production against contact with enclosed equipment.

Mounting Tips

1. Select a convenient position to mount the damper actuator that will provide the desired normal position of the damper, see Figure 3.

2. The damper should be linked for angular rotation of less than 90° that will provide the required flow. This will provide the optimum close-off and controllability. Typically 60° rotation of the damper will provide almost maximum flow.

3. Damper rod that is too long is not rigid enough for good control and damper rod that is too short makes it difficult to adjust the linkage.

4. The best position for the actuator is with the actuator crank arm and the damper crank arm at 90° angle to the damper push rod when actuator is in mid-stroke, see Figure 3.

Figure-2 Dimensions for MS-8304X Series.

Mounting Instructions (Refer to Figure 3)

1. Hold the actuator up to the duct in an appropriate position and mark the four (4) mounting hole positions.

2. With an appropriate drill or punch, pierce the mounting holes marked in step1.

3. Using four (4) screws or bolts (not provided) mount the actuator to the duct.

4. Attach a ball joint to the slot in the damper crank arm at a position from the centerline of the shaft hole in the crank arm; position equal approximately 1-1/2" (38.1 mm) for 90° damper rotation and 2" (50.8 mm) for 60° damper rotation.

5. Rotate the damper to its normal position. Attach and secure the damper crank arm to the damper shaft at an angle (30° for 60° rotation damper and 45° for 90° rotation damper) from the mid-stroke position of the crank arm and pointing toward the actuator.

6. Slide the damper rod through the ball joint on the damper crank arm and into the connector on the actuator. Tighten the nut on the connector on the actuator. Cut off excessive damper rod.

Figure-3 Typical Mounting for MS-8304X Series.

For normally open dampers

, tighten the nut on the ball joint. When the damper is closed the actuator should be 1/16" (1.6 mm) from the extend end of stroke (verify in step 8).

For normally closed dampers

, push the damper closed using the crank arm and tighten the nut on the ball joint while holding the damper closed. This adjustment should

be made when the actuator is powered and positioned so that it is 1/16" (1.6 mm) off its retract positioned so that it is 1/16" (1.6 mm) off its retract position to ensure close-off of the damper.

7. After the actuator is powered and can be controlled, refer to the CHECKOUT section to ensure the damper is linked correctly.

Accessories typically required for mounting per Figure 5

Mounting Tips

1. Select a convenient position to mount the damper actuator that will provide the desired normal position of the damper, see Figure 5.

3. A damper rod that is too long is not rigid enough for good control and a damper rod that is too short makes it difficult to adjust the linkage.

4. The best position for the actuator is with the damper crank arm at a 90° angle to the damper push rod when actuator is in mid-stroke, see Figure 5.
