Damper Actuator,45 in-lb,Non-Spring Return,24V,On/Off/Floating Point

Application	For On/Off and floating point control 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 by means of its standard universal clamp. Shafts up to 3/4? diameter can be accommodated by an accessory clamp.

S1A, S2A	Auxiliary Switch(es)

P...A	Feedback Potentiometers

ZS-100	Weather Shield - Steel

ZS-150	Weather Shield - Polycarbonate

TOOL-06	8 mm & 10 mm Wrench

ZS-T	Terminal Cover for NEMA 2

P370	Shaft Mount Auxiliary Switch

AV6-20	Shaft Extension

ZG-LMSA-1	Shaft Adaptor for 3/8? Diameter Shafts

K-LM20	3/4? [20 mm] Shaft Clamp

ZG-LMSA	Shaft Adaptor for 1/2? Diameter Shafts

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 LMB series provides 95ï¿½ of rotation and a visual indicator which indicates position of the actuator. When reaching the damper or actuator end position, the actuator automatically stops. The gears can be disengaged with manual release on the actuator cover. The LMB24-3? actuators use a sensorless 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. Power consumption is reduced in holding mode. The LMB24-3-S version is provided with one built-in auxiliary switch. This SPDT switch is provided for safety interfacing or signaling, for example, for fan start-up. The switching function is adjustable 0 to 95ï¿½. The auxiliary switch is double insulated so an electrical ground connection is not necessary. Add-on auxiliary switches or feedback potentiometers are easily fastened directly onto the actuator body for signaling and switching functions.

Typical Specification	Floating point, on/off control damper actuators shall be electronic direct-coupled type, which require no crank arm and linkage and be capable of direct mounting to a shaft from 1/4? to 5/8?. Shafts up to 3/4? diameter can be accommodate with an accessory clamp. 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. If required, actuator will be provided with screw terminal strip for electrical connections [LMB(X)24-3-T]. If required, actuators shall be provided with one adjustable SPDT auxiliary switch. Actuators with auxiliary switches must be constructed to meet the requirements for double insulation so an electrical ground is not required to meet agency listings. Run time shall be constant and independent of torque. Actuators shall be cULus listed, have a 5-year warranty, and be manufactured under ISO 9001 International Quality Control Standards. Actuators shall be as manufactured by Belimo.
