  • Page 19: Reflectivity Of Materials

    MWC25M-L2M-B20 series Reflectivity of Materials Reflectivity of Materials Reflectivity and Typical Radar Cross-Sections Microwaves behave similarly to light due to their short wavelength, e.g., 12 mm at 24 GHz or 2.45 mm at 122 GHz. There are therefore the same effects such as diffraction, total reflection, deflection, interference, and some others.

  • Page 20: Dependency Of Materials

    MWC25M-L2M-B20 series Reflectivity of Materials Dependency of Materials Radar waves propagate freely in space in a vacuum. When the waves hit an object, the signal changes due to the influence of the object's properties. Depending on the materials, the radar waves are completely or partially absorbed or reflected.

  • Page 21: Installation

    Check the package contents against your order and the shipping documents to ensure that all items are present and correct. Should you have any questions, direct them to Pepperl+Fuchs. Retain the original packaging in case the device is to be stored or shipped again at a later date.

  • Page 22: Connection

    MWC25M-L2M-B20 series Installation Connection Note Use a shielded 5-wire sensor connection cable to connect the sensor to a J1939 bus. Pay attention to the pin assignment as the standard pin assignment (A-coded M12 plug) differs from the pin assignment in the J1939 specification.

  • Page 23: Mounting And Alignment

    MWC25M-L2M-B20 series Installation Mounting and Alignment Mounting When mounting, observe the following points: • Mount the sensor so that no foreign objects are in the sensing range. • Note the dead band in which objects cannot be detected. If there are objects in the dead band, false reflections may occur.
  • Page 24 MWC25M-L2M-B20 series Installation Curved reflecting object Figure 4.3 When using a curved surface (e.g., cylindrical objects) as the reflecting object, align the radar sensor with the center of the reflecting object. After hitting the reflecting object, in this scenario the main part of the radar signal is scattered in different directions.

Connect the power supply to input 2 of the T-distributor for the CAN/USB converter-SUBD9 using the adapter cable (2.10 mm DC coupling to 4-pin M12 plug).
  • Page 28 MWC25M-L2M-B20 series Commissioning Figure 6.2 Click on "J1939 Communication" to perform a scan of the connected J1939 devices. PACTwareDC finds connected devices. If there is only one device on the bus, the connection to the device is established automati- cally. Continue with step 5.

Figure 6.5 To set the baud rate, select the "Connection Parameter" menu item and then the "Configuration" display. Check the setting or set the baud rate to 250 kbit/s or 500 kbit/s.

  • Page 30: Commissioning Via Can Engineering Tool

    Connect the sensor to the CAN bus and ensure a 24 V DC electric power supply. An extended operating voltage range is possible. Information on this can be found in the datasheet for your MWC25M-L2M-B20 series radar sensor. If necessary, change the communication parameters of the sensor using a suitable CAN Engineering Tool.

    MWC25M-L2M-B20 series Commissioning 6.2.1 Processing the Process Data After successful "Address Claiming," the sensor sends process data immediately. By default, PGN 0xFF00 is enabled and the process data is sent as follows: Byte 0 Byte 1 Byte 2 Byte 3...

  • Page 32: Changing The Device Address

    MWC25M-L2M-B20 series Commissioning 6.2.2 Changing the Device Address After switching on the sensor, it always initially starts with address 128. An "address claiming" process begins with the network management of the J1939 network. An address is then assigned to the sensor; this address is not stored persistently. This means that a new address claiming process with start address 128 is carried out each time the system is restarted.

  • Page 33: Transfer Rate

    MWC25M-L2M-B20 series Commissioning 6.2.4 Transfer Rate See object directory "0x2003:2" when using CAM 11/21 (CANopen Application Message). Alternatively, you can also set the baud rate via PACTware in the communication DTM baud rate, see chapter 6.1. Note After changing the parameter, the power supply must be switched off and on again (power cycle).

  • Page 34: Restoring The Factory Defaults

    MWC25M-L2M-B20 series Commissioning 6.2.6 Restoring the Factory Defaults You can restore the sensor's factory defaults using index 0x5011 "Restore default parameters": 1. Write the signature 0x64616F6C ("daol" corresponds to "load" backward) to object 0x5011:1 of the sensor. Switch the voltage supply to the sensor off and then on again (power cycle).
