M9220-GGx-3 Proportional Electric Spring Return Actuators Installation Instructions
8
Note:
If two stroke limiting stops are applied, 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 two M4 x 10 mm self-tapping
screws provided. Tighten the screws to a torque of
35 lb·in (4 N·m).
4.
Manually reposition the coupler so that the coupler
set screw aligns with the nodule guide that
corresponds to the value determined in Step 2.
Example:
For a rotation range of 65°, mount one stroke
limiting stop 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.

CAUTION: Risk of Electric Shock
.
Disconnect the power supply before making
electrical connections to avoid electric
shock.
MISE EN GARDE : Risque de décharge
électrique.
Débrancher l'alimentation avant de réaliser
tout raccordement électrique afin d'éviter
tout risque de décharge électrique.
!
CAUTION: Risk of Property Damage.
Do not apply power to the system before
checking all wiring connections. Short
circuited or improperly connected wires may
result in permanent damage to the
equipment.
MISE EN GARDE : Risque de dégâts
matériels.
Ne pas mettre le système sous tension
avant d'avoir vérifié tous les raccords de
câblage. Des fils formant un court-circuit ou
connectés de façon incorrecte risquent
d'endommager irrémédiablement
l'équipement.
IMPORTANT:
Make all wiring connections in
accordance with local, national, and regional
regulations. Do not exceed the electrical ratings of
the M9220-GGx-3 Proportional Electric Spring
Return Actuator.
