Proportional Electric Spring Return Actuators

Installation Instructions

Part No. 34-636-1697, Rev. B

Issued February 4, 2009

Supersedes June 20, 2006

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.

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 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 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 th e 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: 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.

Mounting

The M9220-GGx-3 Proportional Electric Spring Return
Actuators can be 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. An M9220­600 Jackshaft Coupler Kit is available for 3/4 to 11/
16 in. or 19 to 27 mm round shafts, or 5/8 and 3/4 in. or

details. If the damper shaft extends less than 3-19/32
in. (91 mm), see the Removable Coupler
further instructions. If the damper shaft extends less
than 1-5/32 in. (29 mm), install an extension
recommended by the damper manufacturer.

section for

Counterclockwise (CCW) Spring Return Direction – Clockwise (CW) Powered Operation

For CCW spring return direction, mount the actuator to
the damper shaft so that Side A of the actuator is away
from the damper as illustrated in Figure 2. With power
applied, the actuator drives CW from the 0° position,
and spring returns CCW.

The coupler may be installed on either side of the
output hub. If the damper shaft is less than 3-19/32 in.
(91 mm) long, insert the coupler in the face of the
actuator closest to the damper. If the damper shaft is
shorter than 1-5/32 in. (29 mm) long, a shaft extens ion
is required to mount the actuator.

Figure 4: Changing the Position of the Coupler

To change the position of the coupler , see Figu re 4 and
proceed as follows:

1. Mount the coupler on either Side A or Sid e B of the
actuator, as determined by the shaft length.

2. Snap the locking clip securely into the coupler
retention groove to retain the coupler.

Manual Override

Use only the supplied manual override crank to
reposition the actuator hub when using the manual
override feature.

IMPORTANT: Applying excessive torque to the
manual override or running the manual override with
a power tool may damage the internal components
of the actuator and cause premature failure.

To reposition the actuator hub, proceed as follows:

1. De-energize the actuator.
