2 M9108, M9116, M9124, and M9132 Series Electric Non-spring Return Actuators Product Bulletin
Application
IMPORTANT: This device is not designed or
intended to be used in or near environments where
explosive vapors or gases could be present, or
environments where substances corrosive to the
device’s internal components could be present.
M91xx actuators are designed to position air dampers
and valves in Heating, Ventilating, and
Air Conditioning (HVAC) systems. Applications
include:
• positioning return air or exhaust dampers
• controlling face and bypass dampers
• positioning blades for variable volume fans
• positioning VG1000 Series ball valves and
VG7000 Series globe valves when used with an
M9000-5xx Valve Linkage
Two each of the following models provide twice the
amount of running torque of a single unit when
mounted in tandem: M9116-GGx or HGx; M9124-AGx,
GGx, or HGx; and M9132-AGx or GGx.
Refer to the manufacturer’s information to properly
size the damper, valve, and/or actuator. Spring return
actuators, such as Johnson Controls M9206 and
M9216 Series, are recommended for use with outdoor
air dampers in cold climates.
Operation
IMPORTANT: The M91xx Series actuator is
intended to control equipment under normal
operating conditions. Where failure or malfunction of
an M91xx actuator could lead to an abnormal
operating condition that could cause personal injury
or damage to the equipment or other property, other
devices (limit or safety controls), or systems (alarm
or supervisory) intended to warn of, or protect
against, failure or malfunction of an M91xx actuator
must be incorporated into and maintained as part of
the control system.
M91xx actuators operate on 24 VAC at 50/60 Hz or
24 VDC. These compact actuators use a DC motor
with stall detection circuitry that operates throughout
the entire stroke. The GGx, HGx, and JGx models
employ noise-filtering techniques on the control signal
to eliminate repositioning due to line noise.
Rotation is mechanically limited to 93° by integral
end-stops. The position of the actuator is marked from
0 to 90° on the cover. An anti-rotation bracket prevents
lateral movement of the actuator. Pressing the spring-
loaded gear release on the actuator cover disengages
the gear train for manual repositioning of the coupler.
