Provide overload protection and disconnect as required.
Actuators are provided with color coded wires. Wire
numbers are provided for reference.
The LM24-SR-T US is provided a screw terminal
instead of cable.
The LM24-SR-T US does not have feedback.
Connect actuator common (Wire 1) to Negative (–) leg
of control circuits only.
Actuators may also be powered by 24 VDC.
A 500Ω resistor (ZG-R01) must be added for 4 to 20
mA control.

LM24-SR (-T) US - Typical Specification:
Control damper actuators shall be electronic direct coupled
type which require no crank arm and linkage. Actuators shall
be UL and CSA listed, have a 5 year warranty, and be man-
ufactured under ISO 9001 International Quality Control
Standards. Actuators shall have Brushless DC motor.
Actuators shall have reversing switch and gear disengage-
ment button on the cover, and be electronically protected from
overload at all angles of rotation. Actuators shall respond to 2
to 10VDC output relative to position regardless of the amount
of damper rotation. A 2 to 10 VDC feedback signal shall be
provided for position indication or master-slave applications.
Actuators shall be as manufactured by Belimo.
An electronic angle of rotation adjustment shall be provided to
reduce the actuators rotation from 100 to 20% while still using
the full input signal and feedback control range. (LM24-SR US)
If required, actuator will be provided with screw terminal strip for
electrical connections (LM24-SR-T US).
