or on/off and floating point control of dampers in HVAC systems. Actuator sizing
s
hould be done in accordance with the damper manufacturer’s specifications.
T
he actuator is mounted directly to a damper sha
f
t up to 1.05” in diameter by means
o
f its universal clamp. A crank arm and several mounting brackets are available for
a
pplications where the actuator cannot be direct coupled to the damper shaft
.

T
he actuator is not

rovided with and does not re

limit switches, but is
electronically protected against overload. The anti-rotation strap supplied with the
a
ctuator will prevent lateral movement.
T
he GMX series
p
rovides 95° of rotation and a visual indicator indicates
p
osition of the
a
ctuator. When reachin
g
the damper or actuator end position, the actuator
a
utomatically stops. The
g
ears can be manually disen
g
a
g
ed with a button on the
a
ctuator cover.
T
he GMX120-3 actuators use a sensorless brushless DC motor, which is controlled by
a
n Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the
a
ctuator’s rotation and provides a digital rotation sensing (DR
