The device saves the history of sent log files: for the main log files, the file with the sending history has the name “LOGSENT.TXT”, for log files with data on battery cells - “CELLSENT.TXT”.

Reset

The BMS Main 3 can automatically restart after the "Charger connected" signal appears. The restart will occur no more often than "Maximum number of resets" per day and no more often than once per hour.

To access settings of periodic device reset, select the "Service → Reset" section:

  • Actual number of resets – a number of successful resets today;
  • Last reset timestamp – time of last device reset.

Errors journal

The BMS Main 3 device maintains a 32-entry errors journal. Each journal entry stores an error occurrence/disappearance timestamp and error flags.

The errors journal can be viewed in the "Service - Errors journal" section:

In this section:

  • Acknowledge the errors – a trigger to acknowledge the errors and clear the "Need acknowledge" signal;
  • Errors 1, 2 to ignore when adding a new record – bitfields with errors to be ignored while write to error journal;
  • Last record – a number of the last entry in the errors journal;
  • Record 1 … Record 32 – entries in the errors journal.

The errors journal is circular: after all 32 positions are filled, the next entry will be placed at position 1.
