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)
INSTALLATION
Caution:
1. Installer must be a qualified, experienced technician.
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
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
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.

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.

Mounting Instructions
Refer to Figures 10 through 13 and 15.
1. Attach the mounting plate to the duct or wall with the
damper shaft protruding through the locator hole in the
mounting plate. If this is not possible, additional shaft
extensions may be used to allow locating the actuator
farther from the damper shaft. Each extension provides 4"
(101.6 mm) of extension to the actuator shaft.
2. Install pivot stud into the correct hole in the actuator
mounting plate (see Figures 10 through 12).
3. Remove the ball joint connector from the actuator.
4. Install the shaft extension onto the actuator shaft.

8. Mount the leaf connector to the damper frame with #10
self-tapping screws that are provided.
9. Thread a 5/16" - 24 hex nut onto the threaded rod and
tighten the two nuts on the threaded rod against the pivot
stud.
10. Tighten the pivot stud nuts to the actuator mounting
bracket and tighten the rod end bolt.
WIRING
The wiring connections are made to 6" (152 mm) color coded
leads. See Figure 17 and Tables 4 through 6 for wiring
information.
Note: All wiring must be Class 1 circuits
Control Leads
Use 18 gage three-conductor twisted leads (Part Number
W-103) for runs up to 500 ft (157 m) between the controller
and the actuator. Use a larger size for longer runs.
Caution: Use 18 gage shielded cable (twisted) when it is
necessary to install the signal leads in the same conduit with
power wiring, or when high RFI/EMI generating devices are
near. Terminate the shield at the controller only on the COM
(-) terminal. Never connect the shieldings to earth ground.
Power Leads
See Table 4 for selection of proper gage wire versus voltage
and length of wire run.

CHECKOUT
After the entire system has been installed and actuator has
been powered up, the following checks can be made for
proper system operation.
Go No Go Test (Two-Position Operation)
1. The actuator should be powered.
2. Disconnect the control leads from the controller.
3. To make the actuator shaft extend fully, short the yellow
lead to the red lead.
4. To make the actuator shaft retract fully, short the yellow
lead to blue lead.
5. Check for proper operation of the valve or damper as the
actuator is operated.
6. Reconnect the control wiring.
Manual Positioning with TOOL-201 (Manual
Positioner)
1. The actuator should be powered.
2. Disconnect the control leads from the controller.
3. Attach the slidewire leads from TOOL-201 to the same
color leads on the actuator.
4. The actuator can be manually positioned by turning the
knob of TOOL-201; turning knob in the increase direction
will make the shaft of the actuator retract and in decrease
direction will make the shaft of the actuator extend.
5. Check for proper operation of the valve or damper as the
actuator is operated.
6. Reconnect the control wiring.
Positioning the Actuators with the Controller
If the sensed media is within the controller’s setpoint range,
the actuator can be positioned by adjusting the controller
setpoint up and down. Check for correct operation of the
actuator (valve or damper) while the actuator is being stroked.
Figure-18 AM-158 Auxiliary Switch Installation.
Auxiliary Switch Kit (AM-158) Installation (See
Figures 18 and 19)
Warning: Risk of electrical shock - open all disconnects
before servicing.
1. Remove 4 x 4 cover from the actuator. Save cover for
reinstallation.
2. Remove single screw at mid-left-hand side of cavity (see
Figure 18). Save screw for reinstallation.
3. Press in simultaneously on the two places indicated by
“X” on Figure 18. The insulator will fold in, perpendicular
to the rest of the insulator.
4. Remove small rectangular piece of insulation in lower
left-hand corner (see Figure 18) if obstructing the four pin
receptacles on the main drive printed circuit board
(P.C.B.).
5. With insulator properly aligned on the auxiliary switch
P.C.B. (see Figure 18), align the four auxiliary switch pins
with the four receptacles on the main drive P.C.B.
6. Once the pins and receptacles are aligned and in contact,
press the auxiliary switch assembly firmly into place. The
auxiliary switch assembly should be slightly raised above
the main drive P.C.B. [approximately 1/8" (3mm)].
Warning: Be sure no wires get pinched.
7. Reinstall screw to hold auxiliary switch assembly firmly in
place.
8. After properly wiring auxiliary switch to the device to be
controlled, rotate auxiliary switch adjustment
potentiometer fully CCW, which will disable the auxiliary
switch.
9. Apply power to actuator and adjust auxiliary switch trip
point to desired position.
10. Replace 4 x 4 cover on the actuator.
