Actuator sizing should bedone in accordance with the damper manufacturer’s specifications.The default parameters for 2 to 10 VDC applications of the …MFT actuator areassigned during manufacturing. If necessary, custom versions of the actuators can beordered. The parameters can be changed by two means: pre-set and customconfigurations from Belimo or on-site configurations using the Belimo PC-Toolsoftware.OperationThe actuator is not provided with and does not require and limit switches, but iselectronically protected against overload. The anti-rotation strap supplied with theactuator will prevent lateral movement.The LHX series provides 4, 8, or 12 in of linear force. The stroke of the gear rack canbe 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 controlledby an Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls theactuator’s rotation and provides a digital rotation sensing (DRS) function to preventdamage to the actuator in a stall condition. Power consumption is reduced in holdingmode.Dimensions (Inches [mm])1.1" [27.8]3.8" [97]5.6" [143]2" [50.8]0.4" [10.2]2.64" [67]BA.69"[17.4].16" [4]0.13" [3.2]162Technical DataLHX24-MFT(-100)(-200)(-300)Power supply24 VAC ± 20% 50/60 Hz24 VDC ± 20%Power consumption2.5 W (1.2 W)Transformer sizing5 VA (Class 2 power source)Electrical connection18 GA plenum rated cable1/2” conduit connectorprotected NEMA 2 (IP54)3 ft [1m] 10 ft [3m] 16 ft [5m]Overload protectionelectronic throughout full strokeControl2 to 10 VDC, 4 to 20 mA (default)Variable (VDC, PWM, floating point, on/off)Input impedance100 kΩ (0.1 mA), 500 1500 (PWM, floating point, on/off)Feedback output U2 to 10 VDC (max 0.5 mA)VDC variableLinear strokeLHX24-MFT-1004 in [100 mm]LHX24-MFT-2008 in [200 mm]LHX24-MFT-30012 in [300 mm]Linear force34 lbf [450 N]Stroke directionreversible with switchManual overrideexternal push buttonRunning time150 seconds per 4" [100mm]variable (75 to 150 seconds)Humidity5 to 95% RH non condensing (EN 60730-1)Ambient temperature-22°F to 122°F [-30°C to 50°C]Storage temperature-40°F to 176°F [-40°C to 80°C]HousingNEMA 2, IP54, UL enclosure type 2Housing materialUL94-5VAAgency listingscULus acc. to UL 60730-1A/-2-14, CAN/CSA E60730-1:02,CE acc. to 2004/108/EEC and 2006/95/ECNoise level (max)35dB(A)Servicingmaintenance freeQuality standardISO 9001WeightLHX24-MFT-1000.81 lbs [0.37 kg]LHX24-MFT-2000.86 lbs [0.39 kg]LHX24-MFT-3000.93 lbs [0.42 kg]† Rated Impulse Voltage 800V, Type of action 1, Control Pollution Degree 3.40024 - 05/10 - Subject to change. © Belimo Aircontrols (USA), Inc.800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA344AccessoriesZ-DS1Rotary Support to Compensate Lateral ForcesZ-KSALinear CouplingP370Shaft Mount Auxiliary SwitchSGA24Min Positioners in NEMA 4 HousingSGF24Min Positioners for Flush Panel MountingPTA-250Pulse Width Modulation InterfaceIRM-100Input Rescaling ModuleADS-100Analog to Digital SwitchZG-R01Resistor for 4 to 20 mA ConversionNSV24 USBattery Back-Up ModuleZG-X40TransformerNOTE: When using LHX24-MFT… actuators, only use accessories listed on this page.Typical SpecificationProportional control damper actuators shall be electronic type, with integrated linear stroking arm. Actuators must provide control in response to a control input from anelectronic controller or positioner. Actuators shall have brushless DC motor technologyand be protected from overload at all angles of rotation. Actuators shall have reversingswitch 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 manufac-tured under ISO 9001 International Quality Control Standards. Actuators shall be as manufactured by Belimo.Wiring DiagramsProvide overload protection and disconnect as required.CAUTION Equipment Damage!Actuators may be connected in parallel if not mechanically mounted to the sameshaft. Power consumption and input impedance must be observed.Actuators may also be powered by 24 VDC.4Position feedback cannot be used with Triac sink controller.The actuator internal common reference is not compatible.Control signal may be pulsed from either the Hot (source)or the Common (sink) 24 VAC line.8Contact closures A & B also can be triacs.A & B should both be closed for triac source and open for triac sink.For triac sink the common connection from the actuatormust be connected to the hot connection of the controller.The ZG-R01 500 resistor may be used.WARNING Live Electrical Components! During installation, testing, servicing and troubleshooting of this product, it may benecessary 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 thesetasks. Failure to follow all electrical safety precautions when exposed to live electrical compo-nents could result in death or serious injury.LHX24-MFT(-100)(-200)(-300)Proportional, Non-Spring Return, Linear Stroke, 24 V, Multi-Function Technology399_08VDC/4-20 mAW399_08PWW399_08On/Off controW399_08Floating Point control40024 - 05/10 - Subject to change. © Belimo Aircontrols (USA), Inc.Next >
