All applicable legal or institutional installation regulations must be complied with during installation.The device may only be opened at the manufacturer's site. It does not contain any parts that can be replaced or repaired by the user.To calculate the torque required, the specifications supplied by the damper manufacturers concerning the cross-section and the design, as well as the installation situation and the ventilation conditions must be observed.The device contains electrical and electronic components and must not be disposed of as household refuse. All locally valid regulations and requirements must be observed.Product featuresOperating modeConventional operation:The actuator is connected with a standard control signal of 0...10 V and drives to the position defined by the control signal. The measuring voltage U serves for the electrical display of the actuator position 0.5...100% and as control signal for other actuators.Operation on Bus:The actuator receives its digital control signal from the higher level controller via the MP-Bus and drives to the position defined. Connection U serves as communication interface and does not supply an analogue measuring voltage.Converter for sensorsConnection option for a sensor (passive or active sensor or switching contact). The MPactuator serves as an analogue/digital converter for the transmission of the sensor signal via MP-Bus to the higher level system.Parametrisable actuators The factory settings cover the most common applications. Single parameters can be modified with the Belimo service tools MFT-P or ZTH EU.Simple direct mountingSimple direct mounting on the damper shaft with a universal shaft clamp, supplied with an anti-rotation device to prevent the actuator from rotating.Manual overrideManual override with push-button possible (the gear train is disengaged for as long as the button is pressed or remains locked).Adjustable angle of rotation Adjustable angle of rotation with mechanical end stops.High functional reliabilityThe actuator is overload protected, requires no limit switches and automatically stops when the end stop is reached.Home positionThe first time the supply voltage is switched on, i.e. at the time of commissioning, the actuator carries out a synchronisation. The synchronisation is in the home position (0%).The actuator then moves into the position defined by the control signal.LM24A-MP-TP Adaptation and synchronisation An adaptation can be triggered manually by pressing the "Adaptation" button or with the PC-Tool. Both mechanical end stops are detected during the adaptation (entire setting range).Automatic synchronisation after pressing the manual override button is configured. Thesynchronisation is in the home position (0%).The actuator then moves into the position defined by the control signal.A range of settings can be adapted using the PC-Tool (see MFT-P documentation) Product featuresAccessoriesGateways Description TypeGateway MP to BACnet MS/TP UK24BACGateway MP to Modbus RTU UK24MOD Electrical accessories Description TypeAuxiliary switch 1x SPDT add-on S1AAuxiliary switch 2x SPDT add-on S2AFeedback potentiometer 140 Ω add-on P140AFeedback potentiometer 1 kΩ add-on P1000AFeedback potentiometer 10 kΩ add-on P10000ASignal converter voltage/current 100 kΩ 4...20 mA, Supply AC/DC 24 V Z-UICPositioner for wall mounting SGA24Positioner for built-in mounting SGE24Positioner for front-panel mounting SGF24Positioner for wall mounting CRP24-B1MP-Bus power supply for MP actuators ZN230-24MP Mechanical accessories Description TypeShaft extension 170 mm ø10 mm for damper shaft ø6...16 mm AV6-20Shaft clamp one-sided, clamping range ø6...20 mm, Multipack 20 pcs.K-ELAShaft clamp one-sided, clamping range ø6...10 mm, Multipack 20 pcs.K-ELA10Shaft clamp one-sided, clamping range ø6...13 mm, Multipack 20 pcs.K-ELA13Shaft clamp one-sided, clamping range ø6...16 mm, Multipack 20 pcs.K-ELA16Anti-rotation mechanism 180 mm, Multipack 20 pcs.Z-ARS180Form fit insert 8x8 mm, Multipack 20 pcs.ZF8-LMAForm fit insert 10x10 mm, Multipack 20 pcs.ZF10-LMAForm fit insert 12x12 mm, Multipack 20 pcs.ZF12-LMAForm fit insert 8x8 mm, with angle of rotation limiter and positionindication, Multipack 20 pcs.ZFRL8-LMAForm fit insert 10x10 mm, with angle of rotation limiter and position indication, Multipack 20 pcs.ZFRL10-LMAForm fit insert 12x12 mm, with angle of rotation limiter and positionindication, Multipack 20 pcs.ZFRL12-LMA Position indicator, Multipack 20 pcs.Z-PITerminal protection IP54, Multipack 20 pcs.Z-TP Tools Description Type Service tool, with ZIP-USB function, for parametrisable andcommunicative Belimo actuators, VAV controller and HVAC performancedevicesZTH EUBelimo PC-Tool, Software for adjustments and diagnostics MFT-PAdapter for Service-Tool ZTH MFT-CConnecting cable 5 m, A: RJ11 6/4 ZTH EU, B: 6-pin for connection toservice socketZK1-GENConnecting cable 5 m, A: RJ11 6/4 ZTH EU, B: free wire end forconnection to MP/PP terminalZK2-GENLM24A-MP-TPElectrical installationSupply from isolating transformer.Parallel connection of other actuators possible.
