to be reconfigured. The calibration data from the original file will be the most accurate because it is the original
data from the factory.
A generic file for the length of the sensor (from the files provided with the MasterLink software) can also be used,
but there may be a minor loss of accuracy (precise calibration data is only available on the configuration the
sensor shipped with). Use these files if the original factory sensor data or subsequent configuration file were not
saved or cannot be retrieved due to electronics board failure.
To download the configuration to the LevelMaster:
1. Follow the steps described in section 8.8, Establish local communication with electronics board.
2. When connection with the unit is established, select the Upload/Download tab.
3. Under Send data to the LevelMaster from the file, click the browse ([...]) button.
4. At the browser, navigate to the folder where the existing configuration file was saved (for example, C:\Program Files
(x86)\ABB\MasterLink).
5. Locate and select the configuration file.
6. Click Open.
7. Click Download Data to LevelMaster.
8. Click OK when the download is complete.
9. If no further maintenance or service procedure is required, restore permanent wiring connections and secure the enclosure
cover back into place.
10. If saving the configuration file for an upgrade or part replacement, proceed to the appropriate procedure.

Upgrade the electronics board

A board upgrade replaces the electronics board part number 2018546-005 with board part number 2104836-001. The purpose
of the upgrade is to support batteryless floats. The older board version does not support these types of floats. With the newer
board version, all float configurations are supported: single or dual, passive, active, or batteryless floats.
The upgrade process is described in detail in the LevelMaster upgrade kit application guide.
Board upgrades may replace an electronics board that is still in working condition.
IMPORTANT NOTE: An existing configuration file can be downloaded to the replacement board to preserve
existing configuration and calibration data stored in the previous board. If the file was previously saved, locate the
file when ready to download to the new board. If the file was not saved and the board being replaced is still in
working condition, obtain the file from the board as described in section 8.9, Preserve sensor data and
configuration. If unable to obtain the file, use the factory default files provided with the MasterLink software.
To upgrade the electronics board:
1. Obtain the LevelMaster upgrade kit application guide. See the Additional information section of this manual for the link to
the document location.
2. Follow the instructions described in the guide.
3. Save the configuration after the upgrade to ensure that the configuration file is up-to-date with the change in boards and/or
floats. Use the procedures described in section 8.9, Preserve sensor data and configuration.

Replace the electronics board

Board replacement requires removing field wiring, but not full removal of the unit from the tank. For convenience, the electronics
board can be configured before it is installed in the enclosure if local connection to the board is difficult or not allowed once the
sensor is inside of the tank.
The following procedure assumes the following:
The board is being replaced without removing the unit from the tank.
