120VAC ON/OFF 180in# S/R ACT| Application | The FSAF_A actuators provide true spring return operation for reliable fail-safe
application and positive close-off on UL555S dampers. The spring return
system provides constant torque to the damper with and without power applied
to the actuator. The FSAF_A series provides 95� of rotation and is provided with
a graduated position indicator showing 0 to 95�. |

| Operation | The FSAF_A series actuators are mounted to the damper axle shaft or jackshaft
(1/2? to 1.05?) via a cold-weld clamp. Teeth in the clamp and V-bolt dig into
the metal of both solid and hollow shafts maintaining a perfect connection. The
specially designed clamp will not crush hollow shafts. The bottom end of the
actuator is held by an anti-rotation strap or by a stud provided by the damper
manufacturer. The actuator is mounted in its fail safe position with the damper
blade(s) closed. Upon applying power, the actuator drives the damper to the
open position. The internal spring is tensioned at the same time. If the power
supply is interrupted, the spring moves the damper back to its fail-safe position.
Note on linkage kits.The correct leg kit for the FSAF_A series is the older ZGAF
US as the actuator has a classic AF frame. However, the spline is the new
generation type and the crank arm required is the KH-AFB. |
