It is possible for the DGA monitor to accumulate excess gases in the measurement system. This can happen, for example, because of an air leak in the oil lines. The DGA monitor will detect this situation and enable device alert code 2112, Excess gas in the system.

To restore normal operation, you must perform the procedure below to bleed the excess gas, and restart measurement after successfully bleeding the system. You must be on site with access to the DGA monitor cabinet, as you have to remove and reattach the bleed plug as instructed.

  1. Connect to the DGA monitor user interface and log in as an Admin user.
  2. Select Service to open the Service tools page, and locate the Bleeding tool.
  3. Select Bleed > Start to start the bleeding sequence.

    The user interface will change to show the bleeding stages and approximate times between the stages.

  4. Follow the progress and instructions on screen. While waiting, open the door of the DGA monitor cabinet and locate the bleed plug.
  5. When instructed to do so, remove the bleed plug from the bleed valve. Select Continue when done.
  6. When instructed to do so, reattach the bleed plug to the bleed valve. Select Continue when done.
  7. When the bleeding sequence is completed, select Continue to exit the tool.
  8. Close and lock the door of the DGA monitor cabinet.
    Even if the bleeding tool does not complete successfully, you must reattach the bleed plug in any case before closing the door of the cabinet.
