Applicatio
For proportional modulation 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 5/8” in diameter
b
means of its universal clamp. Shafts up to 3/4” diameter can be accommodated b
an accessory clamp.
The default parameters for 2 to 10 VDC applications of the …MFT actuator are
assigned during manufacturing. If necessary, custom versions of the actuators can be
ordered. The parameters can be changed by two means: pre-set and custom
confi
urations from Belimo or on-site configurations using the Belimo PC-Tool
software
Operatio
The actuator is not provided with and does not require any limit switches, but is
electronically protected a
actuator w
The LMB(X) series provides 95° of rotation and a visual indicator indicates position of
e actuator. When reaching the damper or actuator end position, the actuator
t
automatically stops. The gears can be manually disengaged with a button on the
actuator cover.
The LMB
Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the
actuator’s rotation and provides a digital rotation sensing (DRS) function to prevent

mode
Add-on auxiliary switches or feedback potentiometers are easily fastened directly onto
the actuator body for signaling and switching functions

Typical Specification
Proportional control damper actuators shall be electronic direct-coupled type, which
equire no crank arm and linkage and be capable of direct mounting to a shaft from
1/4” to 5/8”. Actuators must provide control in response to a control input from an
lectronic controller or positioner. Actuators shall have brushless DC motor technology
and be protected from overload at all angles of rotation. Actuators shall have
eversing switch and manual override on the cover. Run time shall be constant and
ndependent of torque. Actuators shall be cULus listed, have a 5-year warranty, and be
anufactured under ISO 9001 International Quality Control Standards. Actuators shall

During installation, testing, servicing and troubleshooting of this product, it may be
necessary to work with live electrical components. Have a qualifi ed 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 compo
