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 AM... 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 AM...24-3… 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.
The AM...24-3-S version is provided with 1 built-in auxiliary switch. This SPDT switch
is provided for safety interfacing or signaling, for example, for fan start-up. The
switching function is adjustable 0 to 95°. The auxiliary switch is double insulated so
an electrical ground connection is not necessary.
Add-on auxiliary switches or feedback potentiometers are easily fastened directly onto
the actuator body for signaling and switching functions.
