Insert the coupler in the CW face of the actuator for

easier access to the coupler set screw. (Refer to the

Removable Coupler section.)

Removable Coupler

If the damper shaft is less than 3.2 in. (80 mm) long,

insert the coupler in the face of the actuator closest to

the damper.

If the damper shaft is shorter than 1.7 in. (42 mm),

mounting the actuator requires a shaft extension.

To change the coupler’s position, refer to Figure 3 and

proceed as follows:

Figure 3: Changing the Position of the Coupler

1. Pull the locking clip off the coupler, and remove

the coupler from the actuator.

Note: Proceed to the Rotation Range section for a

rotation range less than 90°.

2. Reinsert the coupler into either the CW or CCW

face of the actuator (determined by the shaft

length discussed earlier in this section).

Note: The coupler splines (shown in Figure 3) are

designed to prevent inserting the coupler at the wrong

end of the rotation range.

IMPORTANT: For 0 to 93° rotation, the coupler

must fit as close as possible to, but not on top of, the

metal plate at the spring return position.

3. Snap the locking clip securely into the coupler

groove to retain the coupler in the actuator.

Mounting

Mount the M9206-DNx actuators in any convenient

orientation in economizer applications only. Install the

actuators on a 1/2 in. (13 mm) round damper shaft,

using the M9000-159 anti-rotation bracket. If the shaft

extends less than 3.2 in. (80 mm), refer to the

Removable Coupler section.

Note: The anti-rotation bracket is part of the

economizer installation, but not included with an

M9206-DNx actuator. If the bracket is missing, order

one using product code number M9000-159.

You may use the existing mounting arrangement. For a

new application, mount the actuator as follows:

1. Attach the M9000-159 anti-rotation bracket to the

appropriate face of the actuator, using two

4.5 mm x 13 mm Phillips thread-forming screws

(Figure 4). Use the most appropriate pair of

notches in the bracket tab.

2. Tighten the screws to 15 lb·in (1.7 N·m).

IMPORTANT: The tab on the anti-rotation

bracket must fit into the actuator slot. This prevents

actuator binding and premature wear.

Do not overtighten the sheet metal screws to avoid

stripping the threads. Do not overtighten the Phillips

thread-forming screws to avoid stripping the actuator

threads.

3. Position the M9206-DNx actuator (with the

M9000-159 anti-rotation bracket attached) on the

damper shaft, and secure the bracket to the

mounting surface with two No. 10-16 x 5/8 in. hex

washer-head tapping screws.

4. Rotate the damper to the desired position when

power is lost. If a tight seal is required, grasp the

damper drive shaft with pliers and compress the

damper seals.

5. Hold the damper shaft in this position, and tighten

the coupler set screw. Recommended torque for

the set screw is 150 to 180 lb∙in (17 to 20 N∙m).

Rotation Range

The actuator is factory set for 0 to 93° rotation.

To reduce the rotation range, reposition the coupler as

follows:

1. Make sure that the damper blade is visually

accessible or its position is permanently marked

on the end of the damper shaft (Figure 5).

Figure 5: Damper Position Icons

2. Determine the desired rotation range, and subtract

this amount from 90°.

3. Remove the locking clip from the coupler.

(Shown in Figure 3.)

4. Manually reposition the coupler, so the coupler set

screw aligns with the nodule guide that

corresponds to the value determined in Step 2.

Examples:

1. For a rotation range of 60°, move the coupler so

the coupler set screw is at the 30° nodule guide

(90° - 60° = 30°). Refer to Figure 6.

2. For a rotation range of 45°, move the coupler so

the coupler set screw is midway between

the 40° and 50° nodule guides (90° - 45° = 45°).

Note: The minimum rotation range is 34.5°.

3. Snap the locking clip securely into the coupler

groove to retain the coupler in the actuator.

Auxiliary Switch (DNB Models)

The M9206-DNB-3S model has a built-in auxiliary

switch with a switch adjuster accessible on either face

of the actuator. (See Figure 1 and Figure 2.) The

factory setting is 20°. Refer to the Auxiliary Switch

Rating in the Technical Specifications section.

The switch point is continuously adjustable from

0 to 90°. For the most accurate position of the switch,

refer to Figure 9 and use the method in the following

example.

To change the trip point:

1. Position the actuator in the full spring return

position.

Note: The switch is factory set to trip when the

actuator reaches the 20° position.

2. Turn the switch adjuster until it points to the

desired switch trip point.

3. Connect the switch to an ohmmeter and apply

power to the actuator through the economizer

controller. Modify the settings so the actuator

passes the point where the switch should trip. If

the point is not in the proper position, turn the

switch adjuster again to optimize the setting.
