M9203-AGx-2(Z) Series On/Off and Floating Point Electric Spring Return Actuators Installation Guide
4
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
For CW spring return direction, 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 drives CCW from the 0° position
and spring returns CW.
Removable Coupler
If the damper shaft extends less than 3.31 in. (84 mm),
mount the coupler on the face of the actuator closest to
the damper.
If the damper shaft extends less than 0.79 in. (20 mm),
a shaft extension is required to mount the actuator.
To change the coupler’s position, 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.
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.
