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 AMQB(X) 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 AMQB(X)24-1 actuators use a sensorless 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.
