| Application | For fail-safe, modulating 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. The actuator operates
in response to a 2 to 10 VDC, or with the addition of a 500� resistor, a 4 to
20 mA control input from an electronic controller or positioner. A 2 to 10 VDC
feedback signal is provided for position indication. |

| 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 actuator is double insulated so an electrical ground
connection is not necessary. |
