24v FLTG 22IN/LB S/R W/AUX| Application | For modulation or On/Off, fail-safe control of dampers in HVAC systems.
Actuator sizing should be done in accordance with the damper manufacturer?s
specifications. The actuator is mounted directly to a damper shaft from 1/4?
up to 1/2? in diameter by means of its universal clamp, 1/2? shaft centered
at delivery. A crank arm and several mounting brackets are available for
applications where the actuator cannot be direct coupled to the damper shaft.
Control is floating point from a triac or relay, or On/Off from an auxiliary contact
on a fan motor contactor, controller or manual switch. |

| Operation | The TF 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 consistent torque to the damper with, and without, power applied
to the actuator. The TF series provides 95� of rotation and is provided with a
graduated position indicator showing 0 to 95�. The TF uses a brushless DC
motor which is controlled by an Application Specific Integrated Circuit (ASIC)
and a microprocessor. The microprocessor provides the intelligence to the ASIC
to provide a constant rotation rate and to know the actuator?s exact fail-safe
position. The ASIC monitors and controls the brushless DC motor?s rotation and
provides a digital rotation sensing function to prevent damage to the actuator
in a stall condition. The actuator may be stalled anywhere in its normal rotation
without the need of mechanical end switches. Power consumption is reduced
in holding mode. The TF -S versions are provided with one 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 between 0� and
95�. |
