or on/off and floating point control of dampers in HVAC systems. Actuator sizing
should be done in accordance with the damper manufacturer’s specifications.
The actuator is mounted directly to a damper sha
t up to 1.05” in diameter by means
of its universal clamp. A crank arm and several mounting brackets are available for
applications where the actuator cannot be direct coupled to the damper shaft
Operatio
The actuator is not
rovided with and does not re
uire an
limit switches, but is
electronically protected against overload. The anti-rotation strap supplied with the
actuator will prevent lateral movement
The GMB(X) series provides 95° of rotation and a visual indicator indicates position of
the actuator. When reachin
the damper or actuator end position, the actuator
automatically stops. The
ears can be manually disen
a
ed with a button on the
actuator cover.
The GMB
X
24-3... actuators use a brushless DC motor, which is controlled by an
Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the
actuator’s rotation and provides a digital rotation sensing (DR
) function to prevent
