Tech Sheet

Installation Guide

Application

For On/Off, fail-safe control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications. Control is On/Off from an auxiliary contact or a manual switch. The actuator is mounted directly to a damper shaft up to 1.05” in diameter by means of its universal clamp. A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft. Maximum of two AF’s can be piggybacked for torque loads of up to 266 in-lbs. Minimum 3/4” diameter shaft and parallel wiring.

Operation

The AF..UP-S series actuators provide true spring return operation for reliable fail-safe 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..UP-S series provides 95° of rotation and is provided with a graduated position indicator showing 0° to 95°. The actuator maybe be stalled anywhere in its normal rotation without the need of mechanical end switches. The AF..UP-S versions are provided with two built-in auxiliary switches. These SPDT switches provide safety interfacing or signaling, for example, for fan start-up. The switching function at the fail-safe position is fixed at 10°, the other switch function is adjustable between 10° and 90°. The AF..UP-S actuator is shipped at 5° (5° from full fail-safe) to provide automatic compression against damper gaskets for tight shut off.
