Application
For proportional modulation of dampers in HVAC systems. Actuator sizing should be
done in accordance with the damper manufacturer’s specifications.
The actuator operates in response to a 2 to 10 VDC, or with the addition of a
500 Ω 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 or master-slave
applications.
Operation
The actuator is not provided with and does not require any limit switches, but is
electronically protected against overload. The anti-rotation strap supplied with the
actuator will prevent lateral movement.
The LUB(X) series provides 330° of rotation with angle of rotation limiter, ZDB-LU.
When reaching the damper or actuator end position, the actuator automatically stops.
The gears can be manually disengaged with a button on the actuator cover.

Electrical connection
The LUB(X)24-SR actuators use a brushless DC motor, which is controlled by an
Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the
actuator’s rotation and provides a digital rotation sensing (DRS) 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.

WARNING
G Live Electrical Components!
During installation, testing, servicing and troubleshooting of this product, it may be
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.
W342_08
Proportional control damper actuators shall be electronic type, which require no crank
arm and linkage. Actuators 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 from an
electronic controller or positioner. Actuators shall have brushless DC motor technology
and be protected from overload at all angles of rotation. Actuators shall have reversing
switch and manual override on the cover. Run time shall be constant and independent
of torque. A 2 to 10 VDC feedback signal shall be provided for position indication.
Actuators shall be cUL Approved, have a 5-year warranty, and be manufactured under
ISO 9001 International Quality Control Standards. Actuators shall be as manufactured
by Belimo.
