Damp.Linear, 34lbf, MFT (2-10V), 24V| Application | For proportional modulation of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer?s specifications. 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 configurations from Belimo or on-site configurations using the Belimo PC-Tool software. |

| Operation | The actuator is not provided with and does not require and limit switches, but is electronically protected against overload. The anti-rotation strap supplied with the actuator will prevent lateral movement. The LHX 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 LHX24-MFT? 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. |

| Typical Specification | Proportional control damper actuators shall be electronic type, with integrated linear
stroking arm. Actuators must provide control in response to a 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. 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. |
