Linear force min. 34 lbf for control of damper surfaces up to 11 sq. ft. 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. 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 LHB(X)24-3... series provides 4, 8, or 12 in of linear force. The stroke of the gear rack can be adjusted on both sides in increments of 0.8 in [20 mm] by means of the mechanical end stops. 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. The LHB(X)24-3… 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.

ZG-X40 120 to 24 VAC, 40 VA transformer. TF-CC US Cable conduit connector, 1/2”. Typical Specification Floating point, on/off control damper actuators shall be electronic type, with integrated linear stroking arm. Actuators shall have brushless DC motor technology and be protected from overload at all positions of linear stroke. Actuators shall have reversing switch and manual override on the cover. Run time shall be constant and independent of torque. Actuators shall be cUL listed, have a 5-year warranty, and be manufactured under ISO 9001 International Quality Control Standards. Actuators shall be as manufactured by Belimo. Wiring Diagrams A Actuators with appliance cables are numbered. Provide overload protection and disconnect as required. Actuators may also be powered by 24 VDC. Actuators Hot wire must be connected to the control board common. Only connect common to neg. (-) leg of control circuits. Terminal models (-T) have no-feedback. Actuators may be connected in parallel if not mechanically linked. Power consumption and input impedance must be observed. 1 3 1124 VAC Transformer Blk (1) Common Red (2) + Hot Wht (3) Y Input Line Volts A On/Off 1 3 1124 VAC Transformer Blk (1) Common Red (2) + Hot Wht (3) Y Input Line Volts A Floating Point ComHot 1 3 11A Blk (1) Common Red (2) + Hot Wht (3) Y Input Line Volts
