M9102-AGA-2S and M9104-xGA-2S Series Electric
Non-Spring Return Actuators
Installation Instructions
Part No. 34-636-1220, Rev. E
Issued December 28, 2007
Supersedes May 8, 2007
Applications
The M9102 and M9104 Series Actuators are directmount, non-spring return elec tric 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.
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 pr op er ty,
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.
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.
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 subst ances
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.

3. Make a note of the rotation range and direction,
g
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 shaf t so that
the damper shaft protrudes through the actu at or
coupler, as illustrated in Figure 4.

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.
IMPORTANT: Do not overtighten the mounting
screw. Overtightening may strip the threads.
9. Tighten the square coupler bolt to the shaft using
an 8 mm (5/16 in.) wrench or 10 mm (3/8 in.) 12point socket. Tighten to 11 to 15 N·m
(100 to 130 lb·in).
