M9109-xGx-2 Series Electric Non-Spring-Return Actuators
Description
The M9109 Series direct-mount electric
actuators operate on AC 24 V power and are
available for use with floating or proportional
controllers. These non-spring-return actuators
are easily installed on a VAV box, a round
damper shaft up to 1/2 in. (13 mm) in diameter,
or a 3/8 in. (10 mm) square shaft. The M9109
with an M9000-520 linkage can be used to
control 2 in. (DN50) VG1000 Series ball
valves.
The M9109 models have 80 lb·in (9 N·m)
running torque. They have a nominal
60-second travel time for 90° of rotation at
60 Hz (72 seconds at 50 Hz) with a
load-independent rotation time. The
M9109-xGC-2 models are available with
integral auxiliary switches to perform switching
functions at any angle within the selected
rotation range.
Refer to the M9109 Series Electric
Non-Spring-Return Actuators Product Bulletin
(LIT-120112) for important product application
information.

Applications
The M9109 is used to position balancing,
control, round, and zone dampers in typical
HVAC applications. It can also be used with an
M9000-520 linkage to control VG1000 Series
ball valves. The M9109 mounts directly on the
duct surface, round damper, or small
rectangular damper with an anti-rotation
bracket and two sheet metal screws
(included). Additional linkages or couplers are
not required. For more information, refer to the
M9109 Series Electric Non-Spring-Return
Actuators Installation Instructions
(Part No. 34-636-1190).
Repair Information
If the M9109-xGx-2 Series Electric Actuator
fails to operate within its specifications,
replace the unit. For a replacement actuator,
contact the nearest Johnson Controls®
representative.

1. To avoid excessive wear or drive time on the motor for the -AGx models, use a controller and/or software that provides a time-out function to remove the signal at
the end of rotation (stall). The -GGx models have an auto shutoff to avoid excessive wear or drive time on the motor.
