M9106-AGx-2N0x Series Electric
Non-Spring Return Actuators
Installation
IMPORTANT: Use this M9106-AGx-2N0x Series
Actuator only to control equipment
under normal operating conditions.
Where failure or malfunction of the
actuators could lead to personal
injury or property damage to 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 protect against
failure or malfunction of the
actuators.
IMPORTANT : Utiliser ce M9106-AGx-2N0x Series
Actuator uniquement pour
commander des équipements dans
des conditions normales de
fonctionnement. Lorsqu'une
défaillance ou un dysfonctionnement
du actuators 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 protection
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 actuators.
The actuator may be mounted in any convenient
orientation. When installing the DPT-2015 Differential
Pressure Transmitter on the actuator, mount it so the
tubing connecting the flow pick-up device to the
DPT-2015 creates a moisture trap. This will prevent
condensation from entering the sensor.
Parts Included
• M9106-AGx-2N0x Actuator
• CBL-2000-1 Wiring Harness and DPT-2015-0
Differential Pressure Transmitter (included with the
M9106-AGS-2N02)
• No. 10 self-drilling sheet metal screw
Special Tools Needed
• 5/16 in. (8 mm) square socket
• 3/8 in. (10 mm) 12-point socket
• drill with a 5/16 in. hex nut driver
• digital voltmeter (for troubleshooting the
transmitter)
Mounting
To mount the actuator to a damper:
1. Position the actuator on the damper shaft so the
damper shaft protrudes through the actuator
coupler as shown in Figure 1.
Figure 1: Mounting on the Damper Shaft
2. Make sure the actuator is in the desired mounting
position, parallel to the mounting surface as shown
in Figure 2.
No extra mounting brackets, linkage, or couplers are
required for standard mounting, but wiring terminals
must be accessible and protected from moisture and
corrosive fumes.

3. Verify that the shoulder washer is centered
between the plastic ribs of the actuator housing to
allow actuator movement during rotation.
(See Figure 3.)

To set the actuator stroke, proceed as follows:
1. Grasp the damper shaft firmly with pliers and
rotate the damper fully closed. (See Figure 5.)
Figure 5: Damper Rotation
4. Hold the actuator in place on the damper shaft,
5. Place a 5/16 in. (8 mm) socket on the screw and
IMPORTANT: Do not overtighten the mounting
screw to avoid stripping the threads.
Rotation Range
Make sure that the damper blade is visually accessible
or its position is permanently marked on the end of the
damper shaft as shown in Figure 4.

Figure 3: Shoulder Washer Position
and insert the self-drilling sheet metal screw
through the shoulder washer. (See Figure 3.)
using a drill and extension, drill the screw into the
mounting surface until tight against the washer.
2. Press and hold the gear release lever shown in
Figure 2, and rotate the actuator coupler to the
fully closed position.
3. Make a note of the rotation travel and direction,
either Clockwise (CW) or Counterclockwise
(CCW), required to close the damper.
If rotation is less than 90°, proceed to Less Than
90 Degrees section.
IMPORTANT: Do not remove the sheet metal
screw and force the damper blade closed by rotating
the actuator. This puts additional stress on the gear
train and could reduce the life of the actuator.
90 Degrees
1. Release the gear release lever.
2. Secure the coupler to the shaft using a crescent
wrench or one of the tools from the Special Tools
Needed section to tighten the coupler set screw
against the damper shaft. (See Figure 6.)
