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 jackshaft up to a
1.05” diameter. The actuators must be designed so that they may be used for
either clockwise or counterclockwise fail-safe operation. Actuators shall have a
manual positioning mechanism accessible on its cover. Actuators shall use a
brushless DC motor and be protected from overload at all angles of rotation. Run
time shall be constant and independent of torque. If required, 2 SPDT auxiliary
switches shall be provided with one switch having the capability of being
adjustable. Actuators with switches must be constructed to meet the requirement
for Double Insulation so an electrical ground connection is not required to meet
agency listings. Actuators shall be UL Approved and CSA 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
1
Provide overload protection and disconnect as required.
2
CAUTION Equipment damage!
Actuators may be connected in parallel.
Power consumption and input impedance must be observed.
3
Actuators may also be powered by 24 VDC.
4
For end position indication, interlock control, fan startup, etc., AF24-S
US incorporates two built-in auxiliary switches: 2 x SPDT, 7A (2.5A)
@250 VAC, UL Approved, one switch is fixed at +5°, one is adjustable
25° to 85°.
Meets cULus requirements without the need of an electrical ground
connection.
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.
