f
direct mounting to a jacksha
f

1.05” diameter. The actuators must be designed so that they may be used
f
or either
clockwise or counterclockwise fail-safe o

p
rotected
from overload at all an
g
les of rotation. If required, two SPDT auxiliary switch shall
b
e provided havin
g
the capability of one bein

switches must be constructed to meet the requirements
f
or Double Insulation so
an electrical ground is not required to meet agency listings. Actuators shall be
cULus a

T
he AFB24-MFT, AFX24-MFT actuator provides 95° of rotation and is provided with a
g
raduated position indicator showin
g
0° to 95°. The actuator will synchronize the 0°
mechanical stop or the physical damper or valve mechanical stop and use this point
f
or its zero position durin
g
normal control operations. A unique manual override allows
the settin
g
o
f
any actuator position within its 95° o
f
rotation with no power applied.
T
his mechanism can be released physically by the use of a crank supplied with the
a
ctuator.

NOTE
:
When using AFB24-MFT, AFB24-MFT-S, AFX24-MFT and AFX24-MFT-S actuators, only use
accessories listed on this page.
For actuator wiring information and diagrams, refer to Belimo Wiring
G
uide.
Typical Specification
Sprin
g
return control damper actuators shall be direct coupled type which require no
c
rank arm and linka
g
e and be capable of direct mountin
g
to a
j
ackshaft up to a 1.05”
diameter. The actuator must provide proportional damper control in response to a 2 to
10 VDC or
,
with the addition of a 500
Ω
resistor, a 4 to 20 mA control input
f
rom an
electronic controller or positioner. The actuators must be desi
g
ned so that they may be
u
sed for either clockwise or counterclockwise fail-safe o
p
eration. Actuators shall use
a brushless D
C
motor controlled b
y
a micro
p
rocessor and be
p
rotected from overload
at all an
g
les o
f
rotation. Run time shall be constant, and independent o
f
torque. A 2 to
10 VDC feedback signal shall be provided for position feedback. Actuators shall be
c
ULus Approved and have a 5 year warranty, and be manufactured under ISO 9001
International Qualit
y
Control Standards. Actuators shall be as manufactured b
y
Belimo.

allows the setting o

any actuator position within its 95° o

applied.This mechanism can be released physically by the use o
f
a crank supplied
w
ith the actuator. When power is applied the manual override is released and the
actuator drives toward the

T
he actuator uses a brushless DC motor which is controlled by an Application Specific

and a microprocessor. The microprocessor provides the
intelli

S

C
monitors and controls the brushless D

motor’s rotation and
provides a Digital Rotation

) function to prevent damage to the actuator
in a stall condition. The position

anywhere in its normal rotation without the need of mechanical end switches
.
T
he AFB24-MFT95, AFX24-MFT95 is mounted directly to control sha

the Belimo actuator on

p
er shaft must extend at least 3 1

brackets are
a
vailable

or applications where the actuator cannot be direct coupled to the damper
s
haft. The AFB, AFX series actuators provide true spring return operation for reliable
f

on air tight dampers. The spring return
sy

be mounted in the same
manner as a standard damper shaft application. If more torque is required than one

1. The manual override will only work i
f
no power is available to the actuator.
2. Insert the manual crank (shipped with the actuator) into the hexagon hole located
o
n either side o
f
the actuator. An illustration, located on the label, shows the

n.
3
. Turn the crank in the direction shown on the label
(
clockwise on the “CW” side,
counterclockwise on the “CCW” side). It will take approximately 23 revolutions to
rotate the full 95° of rotation.
4
. To lock the actuator in the required position, flip the switch to the locked position
t
hat is located to the right of the crank on the CCW side of the actuator (left of
t
he crank on the CW side).
5. The manual override may be disengaged in 2 ways.
-
Flip the switch to the unlocked position and the actuator will go to its fail-safe
p
osition.
-
Apply power to wire 1 and 2. The actuator will automatically disengage the
override function and will go to the “on” position in the case of the On/Off
versions. Or, in the case of the proportional versions,
