The AF.24use Series actuators provide true spring return operation for reliable failsafe application and positive close off on air tight dampers. The spring return system provides constant torque to the damper with, and without, power applied to the actuator. The AF.24use Series provides 95 of rotation and is provided with a graduated position indicator showing 0 to 95. the actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches. The AF.24use versions are provided with two builtin auxiliary switches. These SPDT switches are provided for safety interfacing or signaling, for example, for fan startup. The switching function at the failsafe position is fixed at +10, the other switch function is adjustable between +10 to +90. the AF.24use actuator is shipped at +5 (5 from full failsafe) to provide automatic compression against damper gaskets for tight shutoff. made in United States.
