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.

approximately 1/2 turn to achieve 150 to 180 lb∙in
(17 to 20 N∙m) torque.
4. Press and hold the gear release lever, and turn the
coupler by hand to ensure the damper rotates from
end to end.
Proceed to the DPT-2015 section if needed.
Less Than 90 Degrees
If the damper shaft rotation is less than 90°, the stroke
of the actuator has to be adjusted using the scale on
the actuator. (See Figure 6.)
Use the center of the coupler set screw as a pointer to
observe the position on the scale when rotating the
coupler from one side to the other.
Examples:
• For a rotation range of 90°, set both end-stop
set screws fully up as shown in Figure 6.
IMPORTANT: Do not remove the end-stop
set screws, as this could interfere with the actuator’s
operation.
4. Hand tighten the set screw so it remains in this
position.
5. Secure the coupler to the shaft by 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.)
6. Keeping the actuator parallel to the mounting
surface, continue tightening the coupler set screw
approximately 1/2 turn to achieve 150 to 180 lb∙in
(17 to 20 N∙m) torque.
7. Repeat Steps 1 through 3 to set the desired
maximum rotation position.
8. Use the Phillips screwdriver to tighten both
end-stop set screws to a minimum of 25 lb∙in
(2.8 N∙m).
9. Press and hold the gear release lever, and turn the
coupler by hand to ensure the damper rotates from
end to end.
DPT-2015
The M9106-AGx-2N housing has two mounting bosses

procedure in the installation instructions included with
the DPT-2015, DPT-2015 Differential Pressure
Transmitter for VAV Box Applications Installation
Instructions (Part No. 24-7547-18).
• For a rotation range of 60°, leave one end-stop
set screw fully up, and adjust the other one, 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 30 and
75°.
• For a rotation range of 30°, move both end-stop
set screws, so the coupler rotates between the
30 and 60° indicator marks on the scale.
To accurately set the end-stops:
1. Press and hold the gear release lever, and turn the
actuator coupler to the minimum rotation position
for the minimum ventilation flow required.
2. Release the gear release lever.
3. Use a Phillips screwdriver to loosen the end-stop
set screw that is closest to the stop gear. Move the
end-stop set screw in its slot until it is tight against
the stop gear. (See Figure 6.)

Setup and Adjustments
Air Pressure (M9106-AGS-2N02)
The flow pickup device provided with the Variable Air
Volume (VAV) box must be connected to the
DPT-2015 using field-supplied tubing as follows:
1. Cut two lengths of tubing, and connect them to the
flow pickup device.
CAUTION: Risk of Property Damage.
Do not apply power to the system before checking all
wiring connections. Short circuited or improperly
connected wires may result in permanent damage to
the equipment.
MISE EN GARDE : Risque de dégâts matériels.
Ne pas mettre le système sous tension avant d'avoir
vérifié tous les raccords de câblage. Des fils formant
un court-circuit ou connectés de façon incorrecte
risquent d'endommager irrémédiablement
l'équipement.
IMPORTANT: All wiring must be in accordance
with the National Electrical Code and local electrical
regulations.
The actuator requires a 24 VAC control signal and is
compatible with a variety of controllers. Refer to
Figure 8 for the wiring configuration.
IMPORTANT: Make sure the tubing is properly
sized and made of an elastic material, such as
silicone rubber, to ensure airtight connections and
minimize flow measurement errors.
2. Connect the tubing from the flow pickup device to
the corresponding barbed high and low pressure
ports on the DPT-2015. (See Figure 9.)
Note: The upper port is the low pressure port and
indicated as (-)LO on the transmitter.
Figure 8: Wiring Diagra m
Note: To avoid excessive wear or drive time on the
motor, use a controller and/or software that provides a
rotation (stall).
The 20 in. (0.5 m) CBL-2000-1 Wiring Harness,
accepted by Underwriters Laboratories, Inc.® (UL) for
time-out function to remove the signal at the end of
plenum use, is pre-wired with the M9106-AGS-2N02 or
may be ordered separately.

3. Route the tubing so a portion of it is lower than the
DPT-2015. This creates a trap that prevents any
condensation from entering the sensor. Avoid
making any sharp bends in the tubing.
IMPORTANT: Overpressure limit is 15 in. W.C.
(3.74 kPa). Do not blow into ports to test their
operation, as this could damage the sensing
element.
Commissioning
M9106-AGx-2N0x
After wiring is completed, apply power to the controller
and provide signals to the actuator to drive it at least
one complete cycle open and closed.
DPT-2015
To commission the transmitter:
1. Perform the checkout procedure provided in the
controller installation instructions, DPT-2015
Differential Pressure Transmitter for VAV Box
Applications Installation Instructions
(Part No. 24-7547-18), to ensure proper operation
of the transmitter.
Troubleshooting
M9106-AGx-2N0x
If the actuator is not responding or working properly:
• Verify that the actuator assembly is properly
secured to the duct.
• Check that all electrical connections are complete
and power is applied.
• Verify that the damper fully opens and closes,
using the gear release lever on the actuator.
• Check that the actuator stroke is set for the
desired application.
IMPORTANT: Perform commissioning when
the transmitter is permanently mounted and
operating at normal temperatures.
2. Set up and zero using HVAC PRO software
when using a DPT-2015 with a Johnson Controls
VAV Series controller. Refer to the Variable Air
Volume Controller Technical Bulletin
(LIT-6363040) for details.
• Verify that the air lines on the DPT-2015 are
connected to their respective high and low ports
with no kinks in the tubing.
• Check the supply voltage to ensure it is within the
14.5 to 17 VDC range and the polarity is correct.
• Disconnect the air lines from the high and low
ports, and place a voltmeter across the OUT and
GND terminals on the DPT-2015. If the output is
not between 0.4 and 0.6 volts with power applied
to the DPT-2015 in the vertical position, the
transmitter is defective and should be replaced.
Note: Voltage readings may vary by 0.1 volt if the
transmitter is in the horizontal position.
