If the product does not work as it should, go through this troubleshooting procedure.

  1. Depending on the problem, do one of the following.
    • Data messages are coming through, but the measurement values are invalid (////): Check the device status through the CLI with the STATUS command. For message details, see Status message.
    • Data messages are not coming through: Continue with the next step.
      If the device is part of a larger system, for example Vaisala AviMet, check the troubleshooting information of that system first.
  2. Try establishing a maintenance connection remotely, both to data 1 and data 2.

    If you can connect to the device, check the device status through the CLI with the STATUS command. For message details, see Status message.

  3. After checking with the STATUS command, perform a check using the ELOG command.
    For more information, see ELOG command.
  4. If you cannot connect to the device, check the operation of the communication devices at the receiving end.
  5. Go to the site and try the following.
    1. Check that the device is getting power. Inside the interface unit, check the LEDs of the power supply board.
    2. Reset the device. See Resetting FD70 (soft reset).
    3. Check that the AC (mains) power switch and the battery switch are not switched off.
    4. Check the cables and connectors in the flange and inside the interface unit for continuity, bad contacts, or corrosion.
    5. Check that the surge protectors are working.
    6. Check the operation of the communication devices at the transmitting end.
      This includes the devices for data 1 and data 2 and their LEDs.
    7. Check the communication and message settings of data 1 and data 2 through the CLI.
  6. Using terminal software, type the following commands and log the responses to a text file:
    • SYSTEM: information about the device setup.
    • STATUS: information about the internal diagnostics.
    • GET: list of all parameter values.
    • ELOG: display of event log.
  7. If the failure persists, contact Vaisala Technical Support.
