M9102-AGA-2S and M9104-xGA-2S Series Electric Non-Spring Return

Actuators Installation Instructions 1

Applications

The M9102 and M9104 Series Actuators are direct-

mount, non-spring return electric actuators that operate

on AC 24 V power and use plenum cables for field

wiring. Employing a synchronous motor, these

actuators provide floating control (AGA), floating contol

with automatic shutoff (IGA), and proportional control

with selectable 0-10 or 2-10 VDC (GGA).

All models are compact in size and are easily installed

on Variable Air Volume (VAV) boxes, Variable Air

Volume and Temperature (VVT) two-position zone

applications, or small to medium-sized dampers with a

round shaft up to 1/2 in. (13 mm) in diameter, or a

3/8 in. (10 mm) square shaft.

The M9102 Series Electric Non-Spring Return

Actuators provide a running torque of 18 lb·in (2 N·m),

and the nominal travel time is 30 seconds at 60 Hz

(36 seconds at 50 Hz) for 90° of rotation.

The M9104 Series Electric Non-Spring Return

Actuators provide a running torque of 35 lb·in (4 N·m),

and the nominal travel time is 60 seconds at 60 Hz

(72 seconds at 50 Hz) for 90° of rotation.

Installation

The M9102 and M9104 Series Electric Non-Spring

Return Actuators mount directly to the surface in any

convenient orientation using a single No. 10 self-drilling

sheet metal screw (included with the actuator). No

additional linkages or couplers are required. Electrical

connections on the actuator are clearly labeled to

simplify installation.

Parts Included

• one electric non-spring return actuator with an

integrated 48 in. (1.2 m) long cable

• one No. 10 self-drilling sheet metal screw

Special Tools Needed

• 5/16 in. (8 mm) square socket

• #2 Phillips screwdriver

• 3/8 in. (10 mm) 12-point socket

• drill with a 5/16 in. (8 mm) hex nut driver

• digital voltmeter or M9000-200 Commissioning

Tool

IMPORTANT: Use this M9102 or M9104 Series

Electric Non-Spring Return Actuator only to control

equipment under normal operating conditions.

Where failure or malfunction of the electric actuator

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 electric

actuator.

IMPORTANT: Before specifying M9102 or M9104

Series Electric Non-Spring Return Actuators for

plenum applications, verify acceptance of exposed

plastic materials in plenum areas with the local

building authority. Building codes for plenum

requirements vary by location. Some local building

authorities accept compliance to UL 1995, Heating

and Cooling Equipment, while others use different

acceptance criteria.

IMPORTANT: Do not install or use this M9102 or

M9104 Series Electric Non-Spring Return Actuator

in or near environments where corrosive substances

or vapors could be present. Exposure of the electric

actuator to corrosive environments may damage the

internal components of the device, and will void the

warranty.

Mounting

To mount the actuator to a damper:

1. Check that the damper blade is visually accessible,

or its position is permanently marked on the end of

the damper shaft, as illustrated in Figure 2.

2. Grasp the damper shaft firmly with pliers and rotate

the damper fully closed, as illustrated in Figure 3.

3. Make a note of the rotation range and direction,

either Clockwise (CW) or Counterclockwise

(CCW), required to close the damper.

4. Press and hold the gear release lever, and rotate

the actuator coupler to the fully closed position, as

determined in Step 2.

5. Position the actuator onto the damper shaft so that

the damper shaft protrudes through the actuator

coupler, as illustrated in Figure 4.

6. Be certain that the actuator is in the desired

mounting position parallel to the mounting surface,

as illustrated in Figure 5.

7. Hold the actuator in place on the damper shaft, and

insert the No. 10 self-drilling sheet metal screw

through the shoulder washer, as illustrated in

Figure 6.

8. Place a 5/16 in. (8 mm) socket on the screw and

use a drill and extension to drill the screw into the

mounting surface. Drive the screw until it is tight

against the washer.

9. Tighten the square coupler bolt to the shaft using

an 8 mm (5/16 in.) wrench or 10 mm (3/8 in.) 12-

point socket. Tighten to 11 to 15 N·m

(100 to 130 lb·in).

Wiring

M9102-AGA-2S, M9104-AGA-2S

The M9102 and M9104 Series Electric Non-Spring

Return Actuators require an AC 24 V input signal and

are compatible with a variety of VAV and VVT

controllers. These electric actuators include an

integrated 48 in. (1.2 m) long cable. See Figure 7 for

proper wiring.

Note: When using an AGA model, you must use a

VAV or VVT controller and/or software that provides a

timeout function at the end of rotation (stall) to avoid

excessive wear or drive time on the actuator motor.

M9104-IGA-2S

The M9104-IGA Series Electric Non-Spring Return

valve actuators require an AC 24 V input signal and

work with a variety of controllers. These electric

actuators include an integrated 48 in. (1.2 m) long

cable and have an auto-shutoff feature to prevent

excessive wear or drive time on the motor. See

Figure 8 and Figure 9 for proper wiring options.

M9104-GGA-2S

The M9104-GGA Series Electric Non-Spring Return

valve actuators require AC 24 V power and a DC 0(2)

to 10 V or 0(4) to 20 mA controller input signal. These

electric actuators include an integrated 48 in. (1.2 m)

long cable. See Figure 10 for proper wiring.

M9104-GGA actuators are factory set for Direct Acting

(DA) mode and for a DC 0 to 10 V input control signal.

In DA mode, a minimum control signal drives the

actuator to the full Counterclockwise (CCW) position,

and a maximum control signal drives theactuator to the

full Clockwise (CW) position.

For Reverse Acting (RA) operation, a minimum control

signal drives the actuator to the full CW position and a

maximum signal drives the actuator to the full CCW

position.

To change the factory settings (DA, 0-10 V), remove

the actuator cover and adjust the switches on the

circuit board as shown in Figure 12.

CAUTION: Risk of Electric Shock.

Disconnect power supply before making

electrical connections to avoid electric

shock.

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.

IMPORTANT: Make all wiring connections in

accordance with local, national, and regional

regulations. Do not exceed the electrical ratings of

the M9102 or M9104 Series Electric Non-Spring

Return Valve Actuator.

Setup and Adjustments

Commissioning

After wiring is completed, apply power to the VAV or

VVT controller and provide input signals to the actuator

to drive it at least one complete cycle open and closed.

Troubleshooting

If the M9102 or M9104 Series Electric Non-Spring

Return 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 that power is applied

• verify that the damper fully opens and closes, using

the gear release button on the actuator

• check that the actuator stroke is set for the desired

application

Repair Information

If the M9102 or M9104 Series Electric Non-Spring

Return Actuator fails to operate within its specifications,

replace the unit. For a replacement electric actuator,

contact the nearest Johnson Controls representative.
