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.

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.

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.

3. 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.

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.

•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.)

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.

Note: To avoid excessive wear or drive time on the

motor, use a controller and/or software that provides a

time-out function to remove the signal at the end of

rotation (stall).

The 20 in. (0.5 m) CBL-2000-1 Wiring Harness,

accepted by Underwriters Laboratories, Inc.® (UL) for

plenum use, is pre-wired with the M9106-AGS-2N02 or

may be ordered separately.

The plenum-rated 20 in. (0.5 m) CBL-2000-2 and

72 in. (1.8 m) CBL-2000-3 Wiring Harnesses are also

available. (See Table 1.)

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.

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.

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.

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.

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.

DPT-2015

The DPT-2015 must be auto zeroed by a

Johnson Controls VAV controller. If the DPT-2015 is

not operating properly:

•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.
