The actuator is not provided with and does not require any limit switches, but is
electronically protected against overload. The anti-rotation strap supplied with the
actuator will prevent lateral movement.
The AMX series provides 95° of rotation and a visual indicator indicates position of the
actuator. When reaching the damper or actuator end position, the actuator
automatically stops. The gears can be manually disengaged with a button on the
actuator cover.
The AMX24-MFT95 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 (DRS) function to prevent
damage to the actuator in a stall condition. Power consumption is reduced in holding
mode.
Add-on auxiliary switches or feedback potentiometers are easily fastened directly onto the actuator body for signaling and switching functions.
For proportional modulation 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 shaft up to 1.05” in diameter by means
of its universal clamp, 1/2” self-centered default. A crank arm and several mounting
brackets are available for applications where the actuator cannot be direct coupled to
the damper shaft.
The default parameters for 0 to 135 Ω input applications of the …MFT95 actuator are
assigned during manufacturing. If necessary, custom versions of the actuators can be
ordered. The parameters can be changed by two means: pre-set and custom
configuration
