Non-Spring Return Actuators

Installation

IMPORTANT: Use this M9106-xGx-2 Series

actuator only as an operating control. Where failure
or malfunction of the this M9106-xGx-2 actuator
could lead to personal injury or property damage t o
the controlled equipment or other property,
additional precautions must be designed into the
control system. Incorporate and maintain other
devices, such as supervisory or alarm systems or
safety or limit controls, intended to warn of or prot ect
against failure or malfunction of the M9106-xGx-2
Series actuator.

Utiliser ce M9106-xGx-2 Series actuator uniquement
en tant que dispositif de contrôle de fonctionnement.
Lorsqu'une défaillance ou un dysfonctionnem ent du
M9106-xGx-2 actuator risque de provoquer des
blessures ou d'endommager l'équipement contrôlé
ou un autre équipement, la conception du système
de contrôle doit intégrer des dispositifs de prot ection
supplémentaires. Veiller dans ce cas à intégrer de
façon permanente d'autres dispositifs, tels que des
systèmes de supervision ou d'alarme, ou des
dispositifs de sécurité ou de limitation, ayant une
fonction d'avertissement ou de protection en cas de
défaillance ou de dysfonctionnement du
M9106-xGx-2 Series actuator.

Mounting

The actuators are not position sensitive, and may be
mounted in any convenient orientation. They may be
installed on a 3/8 to 1/2 in. (10 to 12.7 mm) round shaft
or a 3/8 in. (10 mm) square shaft, 1.7 in. (43 mm) or
longer. If the shaft is less than 1.7 in. (43 mm), install
an extension recommended by the damper
manufacturer.

To mount the actuator, proceed as follows:

1. Press and hold the gear release lever, and rotate
the coupler to the 0 or 90° position. Release the
gear release lever. (See Figure 1.)

2. Bend or cut the anti-rotation bracket to fit t he
damper frame or duct as shown in Figure 2.

3. Close the damper.

4. Insert the anti-rotation bracket tab into the slot at
the bottom of the actuator (shown in Figure 2), and
slide the actuator onto the shaft.

5. Refer to the “A” Dimensions in Table 1 and
Figure 1 to position the anti-rotation bracket tab
midway in the actuator slot.

IMPORTANT: The anti-rotation bracket tab
must be placed midway in the actuator slot to
prevent actuator binding and premature wear.

6. Use the anti-rotation bracket as a guide, and drill
the holes in the damper frame or duct for the
bracket (based on the measurements obtained in
Table 1 and Figure 1).

Note: When installing the actuator to a
Johnson Controls damper, use the existing holes in
the damper frame.

Note: Keep the actuator parallel to the mounting
surface while tightening the set screw.

10. Press and hold the gear release lever, and turn
the shaft by hand to ensure the damper rotates
from its fully closed to fully open position.

11. Release the gear release lever.

Rotation Range

The damper must be checked as follows:

1. Make sure that the damper blade is visually
accessible or its position is permanently m arked
on the end of the damper shaft as shown in
Figure 3.)

Figure 3: Damper Position Icons

2. Grasp the damper shaft firmly with a pliers and
manually turn the damper to fully open.

90 Degrees

If the damper shaft rotation is 90°:

1. Press and hold the gear release lever shown in
Figure 1, and rotate the actuator coupler and
damper shaft to the fully closed position as shown
in Figure 4.

7. Attach the anti-rotation bracket to the damper

IMPORTANT: Do not overtighten the mounting
screws to avoid stripping the threads.

8. Secure the coupler to the shaft using a 5/16 in.

9. Continue tightening the coupler set screw to

2. Note the rotation travel (30 to 90°) and direction,
either Clockwise (CW) or Counterclockwise
(CCW), required to close the damper.

If rotation is less than 90°, proceed to the Less
than 90 Degrees section.

3. Release the gear release lever.

If the damper shaft rotation is less than 90°, the
rotation range of the actuator has to be adjusted with
the scale on the actuator cover. (See Figure 5. )

Figure 5: Setting the Rotation Range

Use the center of the coupler set screw as a pointer to
observe the position on the scale when rotat i ng the
coupler from one side to the other.

Examples:

• For a rotation range of 90°, move both end-stop
set screws fully up as shown in Figure 5.

• To set a rotation range of 60°, leave one end-stop
set screw fully up, and adjust the other set scr ew
so the coupler rotates between the 30 and 90°
indicator marks on the scale.

• For a rotation range of 45°, adjust both end-stop
set screws so the coupler rotates between t he
30 and 75° indicator marks on the scale.

• To set a rotation range of 30°, move both end-stop
set screws so the coupler rotates between t he
30 and 60° indicator marks on the scale.

IMPORTANT: Do not remove the end-stop
set screws, as this could interfere with the act uator’s
operation.

4. Repeat Steps 1 through 3 to set the desired
maximum rotation position.

5. Tighten both end-stop set screws to a minimum of
25 lb∙in (2.8 N∙m).

6. Turn the actuator coupler and the damper shaft t o
the minimum rotation position.

Setup and Adjustments

Direction of Action

In the Direct Acting (DA) mode, a minimum co ntrol
signal drives the actuator to the full CCW position, and
a maximum control signal drives it fully CW. Fo r
Reverse Acting (RA) operation, a minimum cont rol
signal drives the actuator to the full CW posit i on, and a
maximum control signal drives it fully CCW. To set an
actuator for RA, proceed to the appropriate se ct i on for
the actuator model.

Floating Application: AGx and IGx Models

For CW rotation and RA operation, apply 24 VAC to
the Common (COM) and CW Terminals. For CCW
rotation and DA operation, apply 24 VAC to the COM
and CCW Terminals. (See Figure 6.)

To accurately set the end stops:

1. Press and hold the gear release lever. Turn the
actuator coupler to the minimum rotation posit ion
for the minimum ventilation flow require d.

2. Release the gear release lever.

3. Use a No. 2 Phillips screwdriver to loosen the
end-stop set screw on the actuator that is closest
to the stop gear, and move it in its slot so it is tight
against the stop gear. (See Figure 5.)

AGx and IGx Model

On/Off Application: IGx Model Only

Drive the IGx model as an On/Off actuator by wiring
continuous 24 VAC power to the COM and
CW Terminals. At the same time, command the
actuator to open by powering the CCW Terminal with
24 VAC. To drive the actuator back to the ful l CW
position, remove the 24 VAC signal from the CCW
Terminal.
