Operation
The NFB and NFX 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 NFB and NFX series provides 95deg of rotation and is provided with a graduated position indicator showing 0deg to 95deg. The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches. The NFB24-S and NFX24-S versions are provided with two built-in auxiliary switches. These SPDT switches are provided for safety interfacing or signaling, for example, for fan start-up. The switching function at the fail-safe position is fixed at +10deg, the other switch function is adjustable between +10deg to +90deg. The NFB24, NFB24-S, NFX24 and NFX24-S actuator is shipped at +5deg (5deg from full fail-safe) to provide automatic compression against damper gaskets for tight shut-off.
