The M9220-xxx-3 Actuators are direct mount, spring
return electric actuators that operate on these available
power options:

• AC 24 V at 50/60 Hz or DC 24 V (AGx, BGx, GGx,
HGx)

• AC 120 V at 60 Hz (BAx)

• AC 230 V at 50/60 Hz (BDx)

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 on dampers with
3/8 and 1/2 in. or 10, 12, and 14 mm square shafts,
using the standard shaft clamp inclu ded 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-xxx-3 Electric Spring Return Actuator
provides a running and spring return torque of 177 lb·in
(20 N·m). Two or three 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 xxC models to indicate
end-stop position or to perform switching functions
within the selected rotation range.

Product Overview

The M9220-xxx-3 Electric Spring Return Actuators
provide reliable control of dampers and valves in
Heating, Ventilating, and Air Conditioning (HVAC)
systems.

IMPORTANT: Use this M9220-xxx-3 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-xxx-3 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.

Operation

The M9220-xxx-3 Actuators are available for use with
on/off, floating, and proportional controllers.

On/Off Control (M9220-Bxx-3 Actuators)

When power is applied, the actuator drives open and
the output hub rotates against the spring from -5 to 90°.
The actuator is electronically overload protected should
the actuator stall before reaching 90°. It holds position
at the end of the stroke until power is removed. When
power is removed, the actuator spring returns to the

-5° position.

An M9220-603 adjustable stop kit is available to limit
the stroke of the actuator between 30 and 90° in 5°
increments. M9220-BxC-3 actuators include two
integral Single-Pole, Double-Throw (SPDT) auxiliary
switches. One switch is set to trip at 11° as the actuator
is spring return closed.

Floating Control (M9220-Axx-3 Actuators)

Note: The information in this section assumes that
Side A of the actuator (Counterclockwise [CCW] spring
return) is facing you and the Direct Acting/Reverse
Acting (DA/RA) selector switch is set in the DA
position.

The actuator receives power by applying AC/DC 24 V
between the black (common) and red (+AC/DC 24 V)
wires. A controller applies power between the black
and gray or black and orange wires to command the
actuator to drive Clockwise (CW) or CCW at a constant
speed, independent of load.

Applying AC/DC 24 V be twe e n the bl a ck and gr ay
wires causes the actuator to drive CW from -5 toward
90° at a constant speed, independent of load. The time
required to drive full stroke from 0 to 90° is nominally
150 seconds. When AC/DC 24 V power between the
black and gray wires is removed, the actuator stops
and holds its position. The longer power is applied
between the black and gray wires, the farther the
actuator rotates toward the 90° position.

Applying AC/DC 24 V power between the black and
orange wires causes the actuator to drive CCW toward
the -5° position. The longer AC/DC 24 V power is
applied between the black and orange wires, the
farther the actuator travels toward the -5° position.
When power between the black and orange wires is
removed, the actuator stops and holds its position.

M9220-xxx-3 Electric Spring Return Actuators Product Bulletin2

Changing the DA/RA switch from DA to RA reverses
the direction the actuator drives when power is applied
between the black and gray or black and o range wir es.
The actuator is overload protected should it stall
anywhere within its stroke. If the actuator stalls, it
retries once after 2 minutes, assuming AC/DC 24 V is
still applied.

If power is lost between the black (common) and red
(+AC/DC 24 V) wires, the actuator spring returns to the

-5° position. If power between the black and red wires

is momentarily interrupted, the actuator drives to the

-5° position and waits for the controller to command it

in either the CW or CCW direction.

Proportional Control (M9220-GGx-3 Actuators)

Note: The information in this section assumes that
Side A of the actuator (CCW spring return) is facing
you and the control selector switch is set to the
0 …10 V CW position.

The actuator is powered with AC/DC 24 V power
between the black (common) and red (+AC/DC 24 V)
wires. A proportional controller provides a DC 0 to 10 V
signal between the black (common) and gray (control
signal input) wires.

As the control signal increases from DC 0 to 10 V, the
actuator drives CW from the -5 to 90° position. The
position at which the actuator stops is proportional to
the control signal. The actuator provides about
120 steps of control.

As the signal decreases, the actuator reverses
direction and drives CCW toward the -5° position. A
DC 0 to 10 V feedback signal is provided between the
black (common) and orange (DC 0 to 10 V feedback
signal output) to indicate the position of the actuator.

The direction in which the actuator drives with an
increasing control signal can be reversed by
positioning the selector switch to the DC 0... 10 V CCW
position. When the actuator is placed in this position,
and it is at the 90° position with a DC 0 V control signal,
the actuator proportionally drives to the -5° position as
the control signal increases.

The actuator spring returns when power is interrupted
between the black and red wires. When power returns,
the actuator drives to the fully spring-return position to
establish an end-of-stroke position, then drives to the
position commanded by the DC 0 to 10 V controller.

This model has a selector switch that provides
operation for DC 2 to 10 V controllers. This switch
allows a CW or CCW rotation as the control signal
increases from DC 2 to 10 V. The feedback signal
between the black and orange wires changes to
DC 2 to 10 V when the input signal selector is set to the
DC 2...10 V CW or CCW position.

The M9220-GGx-3 actuators can be controlled by a
DC0to20mA or DC4to20mA controller by placing
a field furnished 1/4 watt 500 ohm resistor between the
black (common) and orange (+DC 0([4] to 20 mA
control signal input) wires.

Proportional Control/Adjustable (M9220-HGx-3 Actuators)

The M9220-HGx-3 actuators operate in a similar
manner to the M9220-GGx-2 actuators, except the
M9220-HGx-3 actuators have an adjustable start
voltage, which can be programmed between
DC 0 to 10 V. The span adjustment can be
programmed between a DC 2 to 10 V range, allowing
the actuator to operate between DC 0 to 20 V. The
M9220-HGx-3 actuator is programmed in the factory
for DC0to10V.

For this actuator, the feedback signal between the
black and orange wires always provides a DC 0 to 10 V
output, regardless of the start voltage or span selected.

Repair Information

A number of replacement parts are available; see
Table 2 for more details. If the M9220-xxx-3 Electric
Spring Return Actuator fails to operate within its
specifications, replace the unit. For a replacement
