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 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: Utiliser ce M9220-GGx-3 Proportional

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.
Clockwise (CW) Spring Return Direction –
Counterclockwise (CCW) Powered Operation
To change the spring return direction to CW, mount the
actuator to the damper shaft so that Side B of the
actuator is away from the damper as illustrated in
Figure 3. With power applied, the actuator now drives
CCW from the 0° position, and spring returns CW.
Removable Coupler
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 extension
is required to mount the actuator.

To change the position of the coupler, see Figure 4 and
proceed as follows:
1. Mount the coupler on either Side A or Side 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.
To reposition the actuator hub, proceed as follows:
1. De-energize the actuator.
2. Insert the hex end of the manual override crank
into the manual override adjustment point on the
face of the actuator.
3. Rotate the manual override crank in the direction
indicated by the arrow on the label.
Note: The actuator requires 27 rotations of the
manual override crank from the fully spring return
position to fully reposition the actuator hub. At the
end of travel, the rotational resistance increases;
do not force the actuator hub past this point.
4. Rotate the manual override crank a half turn in the
opposite direction to lock the actuator hub in place.
Note: To unlock the actuator hub, rotate the
manual override crank in the direction indicated by
the arrow on the label. The actuator hub
automatically unlocks when power is applied to the
actuator, and returns the actuator to normal drive
and spring return operation.
Mounting the Actuator
To mount the actuator, proceed as follows:
1. See the dimensions in Figure 5 and Table 2 to
ensure the correct positioning of the anti-rotation
bracket.
2. Bend or cut the anti-rotation bracket to fit the
damper frame or duct as illustrated in Figure 6.
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.

IMPORTANT: The tab on the anti-rotation bracket
must fit midpoint in the actuator slot. Positioning the
tab midpoint in the slot prevents actuator binding
and premature wear, and makes actuator removal
easier.

Note: You can bend the anti-rotation bracket to fit
a round damper.
3. Drill mounting holes in the damper frame or duct
using the anti-rotation bracket as a guide (based
on the measurements obtained in Table 2 and
Figure 5).
4. Secure the anti-rotation bracket to the damper
frame or duct using the two M3 x 9.5 mm
self-drilling sheet metal screws provided and a
1/4 in. (6 mm) blade screwdriver or 5/16 in. (8 mm)
nut driver.
5. Slide the actuator onto the damper shaft, and
position the tab of the anti-rotation bracket into the
slot at the bottom of the actuator as illustrated in
Figure 6.
6. Rotate the damper blades to the desired position if
the power is lost. To ensure a tight seal, insert the
manual override crank and turn it in the direction
indicated by the arrow on the label five turns; the
position indicator should be near the 0° position on
the scale. Quickly rotate the manual override crank
a half turn in the opposite direction to temporarily
lock the actuator hub in place.
7. Evenly hand tighten each clamp nut onto the
U-bolt, keeping the actuator flat. Secure the U-bolt
to the damper shaft and tighten to a torque of 100
to 125 lb·in (11 to 14 N·m).
8. To release the spring, turn the manual override
crank in the direction indicated on the label; the
actuator spring returns to its starting position. If this
step is omitted, the spring releases automatically
when power is applied to the actuator.
9. Remove the manual override crank and store it in
an unused mounting hole.
10. Apply power long enough for the actuator to travel
a full stroke, and verify that the actuator rotates
freely throughout the range.
Note: If electric power is not available, complete
this verification by reinserting the manual override
crank and turning it in the direction indicated to
rotate the coupler to the fully open position.
Rotation Range Using Optional
M9220-603 Adjustable Stop Kit
The actuator is factory set for 90° rotation, and its
rotation range is limited in 5° increments to a minimum
of 30°. Stroke limiting stops are attached in the field to
the shaft coupler side of the actuator to reduce the
rotation range. Attaching a stroke limiting stop in the
furthest mounting position reduces the rotation range of
the actuator by 5°. Each progressive mounting position
reduces the rotation range an additional 5°.
1. Check that the damper blade is accessible or that
its position is permanently marked on the end of
the damper shaft as illustrated in Figure 7.
Note: Two stops are stacked on top of each other
and assembled with a single screw.
IMPORTANT: Do not overtighten the mounting
screws to avoid stripping the threads. Be certain that
the tab on the anti-rotation bracket remains properly
positioned in the slot on the actuator, and that the
actuator remains parallel to the mounting surface.

2. Determine the desired rotation range. If a 65 to
90° rotation range is desired, add two stroke
limiting stops stacked on each other to one side of
the coupler. If a 35 to 60° rotation range is desired,
add a second set of two stops stacked on each
other to the other side of the coupler.
Note: If both rotational ranges of adjustable stops
are required (35° - 60° & 65° - 90°), use the
manual override crank to position and lock the
actuator in a mid-stroke position to gain access to
both stroke limiting stop mounting positions.
3. Mount the stroke limiting stops in the desired
position using the M4 x 14 mm self-tapping screws
provided. Tighten the screws to a torque of 35 lbin
(4 Nm).
Example:
For a rotation range of 65°, mount two stacked
stroke limiting stops in the minimum stroke position
as illustrated in Figure 8.
Wiring
The M9220-GGx-3 Proportional Electric Spring Return
Actuator provides reliable, integrated damper control.
An AC 24 V at 50/60 Hz or DC 24 V input signal
between the black and red wires, and a
DC 0(2) to 10 V input control signal, causes the output
hub to rotate from -5 to 90° (unless an external
mechanical limit is reached).
Once the actuator reaches the commanded position, it
holds that position until power is removed. If power is
removed, the actuator spring returns to its
-5° position (unless an external mechanical limit is
reached). A stall condition while driving between
-5 to 90° causes the output hub to stop motion and
hold its position until power is removed. Rotation is
mechanically limited to the -5 and 90° positions by
integral end-stops. Optional end-stops are available to
limit the output hub travel. An anti-rotation bracket
prevents rotational movement of the actuator body.
See Figure 9, Figure 10, and Figure 11 for proper
wiring of the M9220-GGx-3 Proportional Electric Spring
Return Actuator.

Setup and Adjustments
Direction of Action
The M9220-GGx-3 Proportional Electric Spring Return
Actuators are factory set for Direct Acting (DA)
operation. In DA mode, applying an increasing input
signal to the control input drives the actuator away from
the spring return position. Reverse Acting (RA)
operation is also available. In RA mode, applying an
increasing input signal to the control input drives the
actuator toward the spring return position. Figure 12
and Figure 13 indicate how the drive direction for the
actuator depends on the spring return direction and the
position of the mode selection switch.
Mode Selector Switch and CAL Function
The M9220-GGx-3 Proportional Electric Spring Return
Actuators are factory set at Direct Acting (DA), DC 0 to
10 V control input (Figure 13). To change to RA
operation, move the mode selection switch from DA to
RA. The DC input signal is selectable from
DC 0 to 10 V or from DC 2 to 10 V, which corresponds
to 0 to 90° rotation. If the rotation range is reduced, the
end-stop is reached with a reduced input signal. For
example, if a DC 0 to 10 V input signal is selected and
the rotation range is limited to 75°, the end-stop is
reached at DC 8.3 V. If an external 500 ohm resistor is
placed across the input (see Figure 10), the switch
positions then select between 0-20 mA or 4-20 mA.
The CAL function enables the actuator to redefine the
selected control input range proportionally across a
reduced rotation range. The actuator stores the
reduced rotation range in nonvolatile memory (retains
data when power is lost or removed).
To calibrate the control input range, proceed as follows:
1. With power off, move the mode selection switch to
the CAL position (Figure 13). Then, energize the
actuator. The actuator automatically rotates until
the end-stops are found, and proportionally
reconfigures the control input range to the reduced
rotation range.
2. Return the mode selection switch to the desired
selection (example: DA, 0 to 10 VDC control input).
Note: During normal operation, if the actuator
stroke increases due to seal or seat wear, the input
is redefined to the increased rotation range in
approximately 0.5° increments.
3. If the actuator mounting position is changed or if
the linkage is adjusted, repeat Steps 1 and 2 to
reinitiate the CAL function.
Note: To repeat calibration with power applied, move
the mode selection switch out of the CAL position for at
least 2 seconds before returning it to the CAL position.
Auto calibration begins five seconds after you return it
to the CAL position.

Tandem Operation: GGx Master with
GGx subordinates
The tandem configuration (Figure 14 and Figure 16)
provides twice (with two actuators) or triple (with three
actuators) the running and spring return torque of a
single actuator, or 354 lb·in (40 N·m), 531 lb·in
(60 N·m). The actuators may be mounted in tandem
using the M9000-158 Tandem Mounting Kit. To mount
a third actuator, user-configured bracketing is required.
Follow these guidelines for tandem operation:
• Two or three M9220-GGx-3 actuators may be
operated in tandem on the same shaft. If mounting
two actuators, see Figure 14; for three actuators,
see Figure 16.
• Each actuator requires separate 24 volt power.
When two or more actuators connected in tandem
share a common power source, the total maximum
power draw is actually 1.5 times the normal
running current for each actuator.
(Total Power = Number of Actuators x Running
Power x 1.5).
• Only one of the actuators can be configured as the
master. Set the selector switch to the master
position (Figure 15).
• The other GGx actuator(s) must be configured as
subordinate(s), by setting the tandem selector
switch to the subordinate position.
• The master can accept DC 0-10 V or DC 2-10 V, or
4-20 mA command signals based on the master’s
switch settings and/or external resistor.
• The master and subordinate(s) must have
matching RA/DA settings.

• The master and subordinate(s) must spring return
in the same direction.
• Once tandem-operating actuators are mounted to
a damper shaft, manual override is no longer an
available function.
The feedback wire of the master (orange) is connected
to the command wire(s) of the subordinate(s)(gray). As
the master moves response to position commands, the
master sets its feedback wire to 0 volts if moving
counterclockwise, 5 volts if holding, or 10 volts if
moving clockwise.
Each subordinate actuator must have its tandem
selector switch (Figure 15) set on the subordinate
setting. Its gray command wire must be connected the
master’s orange feedback wire.
Position information, 0-10 (or 2-10) volts, is available
on the subordinate actuator’s feedback wire (orange).
Note: Electrical override still functions after the
actuators configured for tandem operation are mounted
to a damper shaft. The actuator has a 150-second
drive time when operating in this mode.
Auxiliary Switches (GGC Model Only)
The GGC models include two integral auxiliary
switches with a switch adjuster accessible on either
face of the actuator (as illustrated in Figure 2 and
Figure 3). The nominal factory setting for Auxiliary
Switch No. 1 is 11° closing, and the nominal factory
setting for Auxiliary Switch No. 2 is 81° opening
(relative to a 0 to 90° rotation range). See the
Technical Specifications table for the auxiliary switch
ratings.
The switch point of Auxiliary Switch No. 1 is fixed. The
switch point of Auxiliary Switch No. 2 is independently
and continuously adjustable from 25 to 95°. See
Figure 17 and use the method in the following example
for the most accurate positioning of Auxiliary Switch
No. 2.
To change the switch point of Auxiliary Switch No. 2,
proceed as follows:
1. Position the actuator in the full spring return
position.
Note: Auxiliary Switch No. 2 is factory set to trip
when the actuator reaches the 81° position.
!
WARNING: Risk of Electric Shock.
Disconnect or isolate all power supplies
before making electrical connections. More
than one disconnect or isolation may be
required to completely de-energize
equipment. Contact with components
carrying hazardous voltage can cause
electric shock and may result in severe
personal injury or death.
AVERTISSEMENT : Risque de décharge
électrique.
Débrancher ou isoler toute alimentation
avant de réaliser un branchement
électrique. Plusieurs isolations et
débranchements sont peut-être nécessaires
pour -couper entièrement l'alimentation de
l'équipement. Tout contact avec des
composants conducteurs de tensions
dangereuses risque d'entraîner une
décharge électrique et de provoquer des
blessures graves, voire mortelles.

2. Rotate the switch adjuster until it points to the
desired switch point.
3. Connect Auxiliary Switch No. 2 to a power source
or an ohmmeter, and apply power to the actuator.
The actuator moves to the fully open position and
holds while power is applied.
4. Observe the switch point. If required, repeat
Steps 2 and 3.
Repairs and Replacement
A number of replacement parts are available; see
Table 1 for more details. If the M9220-GGx-3
Proportional Electric Spring Return Actuator fails to
operate within its specifications, replace the unit. For a
