a. If the LevelMaster is an intermediate unit on a RS-485 bus:
i. For boards with part number 2018546-005 verify that JP1 pins 5-6 and 9-10 are jumpered (factory default).
ii. For boards with part number 2104836-001 leave the default configuration (no change is required).
b. If the LevelMaster is the only unit installed, or it is the last unit on a RS-485 bus:
i. For boards with part number 2018546-005 verify that JP1 pins 5-6, 7-8, and 9-10 are jumpered.
ii. For boards with part number 2104836-001 terminate as described in section 5.3.2, Configuring RS-485 bus
termination .
13. Save configuration for backup as described in section 8.9. Preserve sensor data and configuration .
14. Disconnect the laptop from the electronics board.
15. Re-insert the communication and power connector(s) onto the new board.
16. If connected to a Totalflow flow computer or remote controller, verify that no errors are displayed and that measurement
readings are updated by the LevelMaster application (PCCU).
17. Reinstall the enclosure cover.
Configure the new electronic board with a factory default configuration file
Use this procedure if configuring the new board with one of the default files included with the MasterLink 2.0 software. Using the
default file provides only calibration data for the specific length of the unit. Other basic parameters must be manually configured
to match the existing configuration.
IMPORTANT NOTE: 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 for the sensor or
coil assembly is only available on the original board the sensor shipped with). Use default configuration files if the
original factory sensor data or subsequent configuration file were not saved or cannot be retrieved due to
electronics board failure.
To configure the board with a default file:
1. Click the Upload/Download tab.
2. Under the Send data to the LevelMaster option, click the browse button ( […]) .
3. At the browser, navigate to the default file folder applicable to the new board.
a. For example, for boards with part number 2018546-005, the file may be located at C:\Program Files
(x86)\ABB\MasterLink\DefaultDat.
b. For example, for boards with part number 2104836-001, the file may be located at C:\Program Files
(x86)\ABB\MasterLink\DefaultDat\7.0 Head board.
4. Locate the file for the correct length of sensor and click Open .
a. For example, for a 20 foot sensor with a 2018546-005 board, select the "dual_20ft.dat " file from the DefaultDat
folder.
b. For example, for a 20 foot sensor with a 2104836-001 board, select the "Dual_20ft_batteryless.dat" file from the 7.0
Head board folder (Figure 62).
