Applications
The M9220-GGx-3 Proportional Electric Actuators are
direct-mount, spring return electric actuators that
operate on AC/DC 24V power. These bidirectional
actuators do not require a damper linkage, and are
easily installed on dampers with 1/2 to 3/4 in. or 12 to
19 mm round shafts, or 3/8 and 1/2 in. or
10, 12, and 14 mm square shafts using the standard
shaft clamp included with the actuator. An optional
M9220-600 Jackshaft Coupler Kit is available for
3/4 to 1-1/16 in. or 19 to 27 mm round shafts, or
5/8 and 3/4 in. or 16, 18, and 19 mm square shafts.
A single M9220-GGx-3 Series Proportional Electric
Spring Return Actuator provides a running and spring
return torque of 177 lb·in (20 N·m). Two or three like
models mounted in tandem deliver twice or triple the
torque (354 lb·in [40 N·m] or 531 lb·in [60 N·m]).
Integral line voltage auxiliary switches are available on
the GGC models to indicate end-stop position or to
perform switching functions within the selected rotation
range.
Installation
The M9220-GGx-3 Proportional Electric Spring Return
Actuators mount directly to the surface in any
convenient orientation using two M3 x 9.5 mm
self-drilling sheet metal screws and the anti-rotation
bracket (parts included with the actuator). No additional
linkages or couplers are required. Electrical
connections are color-coded and identified with
numbers permanently marked on the actuator cable.
A tag on the actuator cable identifies the electrical
connections, and wiring details are also included on the
actuator housing.

IMPORTANT: Use this M9220-GGx-3 Proportional
Electric 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: Do not install or use this
M9220 GGx-3 Proportional Electric 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.
