M9106-xGx-2 Series Electric
Non-Spring Return Actuators
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 lbin (2.8 Nm).
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.
