The LC Level Controller family USER MANUAL may be downloaded here.

The LC_Config application sofware provides an Windows based graphical interface for the LC product family. Using an Modbus interface the program allows:

  • Monitoring the state of all control functions
  • Configuring of all operating parameters
  • Project management tools
  • Saving and loading configurations to disk
  • Printing configuration reports
  • Operating remote units in Simulation Mode

The FREE software is available here.

NOTE: The software supports an 'offline' mode allowing the capabilities of the LC family to be evaluated with no hardware connected. To connect to the LC controller a APB-DUSB adaptor is required.

The LC-6 Controller provides additional I/O using an APB-22ERD exapansion module, providing additional outputs to indicate individual pump error and warning status information and providing secondary discrete inputs as a backup to the linear (analog) level input. 

The LC Controller provides a stand alone solution for liquid level control and monitoring. To connect to a Modbus network an APB-EXPMC adaptor will be required. The optional Windows based LC_Config software requires either an APB-EXPMC Modbus adaptor or a APB-DUSB programming cable.
