Torque min. 18 in-lb, for control of air dampers
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 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.
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 90°.
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 TF24-S US versions are provided with 1 built-in auxiliary switch. This SPDT
switch is provided for safety interfacing or signaling, for example, for fan startup. The switching function is adjustable between 0° and 95°.
SAFETY NOTE
Screw a conduit fitting into the actuator’s bushing. Jacket the actuator’s
input and output wiring with suitable flexible conduit. Properly terminate the
conduit in a suitable junction box.

Typical Specification
On/Off spring return damper actuators shall be direct coupled type which
require no crankarm and linkage and be capable of direct mounting to a shaft
up to a 1/2” diameter and center a 1/2” shaft. The actuators must be designed
so that they may be used for either clockwise or counterclockwise fail-safe
operation. Actuators shall be protected from overload at all angles of rotation.
If required, 1 SPDT auxiliary switch shall be provided having the capability of
being adjustable. Actuators with auxiliary switch must be constructed to meet
the requirements for Double Insulation so an electrical ground is not required
to meet agency listings. Actuators shall be cULus listed certified, have a 5 year
warranty, and be manufactured under ISO 9001 International Quality Control
Standards. Actuators shall be as manufactured by Belimo.
Wiring Diagrams
Provide overload protection and disconnect as required.

WARNING Live Electrical Components!
During installation, testing, servicing and troubleshooting of this product, it maybe
necessary to work with live electrical components. Have a qualified licensed electrician
or other individual who has been properly trained in handling live electrical components
perform these tasks. Failure to follow all electrical safety precautions when exposed to live
electrical components could result in death or serious injury.
