Part No. 34-636-1506, Rev. F
Issued July 14, 2015
Applications
The M9102 and M9104 Series Actuators are directmount, non-spring return elec tric actuators that operate
on AC 24 V power. Employing a synchronous motor,
these actuators provide floating control (AGA), floating
control with automatic shut-off (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 13 mm in diameter, or a 10 mm
square shaft.
The M9102 Series Electric Non-Spring Return
Actuators provide a running torque of 2 N·m, and the
nominal travel time is 36 seconds at 50 Hz for 90° of
rotation.
The M9104 Series Electric Non-Spring Return
Actuators provide a running torque of 4 N·m, and the
nominal travel time is 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 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: Utiliser ce M9102 or M9104 Series
Electric Non-Spring Return Actuator uniquement
pour commander des équipements dans des
conditions normales de fonctionnement. Lorsqu'une
défaillance ou un dysfonctionnement du electric
actuator 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 electric
actuator.

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: 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.

3. Press and hold the gear release lever, and rotate
the actuator coupler to the fully closed position.
4. Make a note of the rotation range and direction,
either Clockwise (CW) or Counterclockwise
(CCW), required to close the damper.
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.
6. Be certain that the actuator is in the desired
mounting position parallel to the mounting surface,
as illustrated in Figure 5.
