In this section:

  • Reset device;
  • Reset device and start bootloader;

When you select the “Reset device and start bootloader” option, the bootloader is activated, which is used to update the firmware of the board via Updater in ElectricDeviceMonitor.

Settings

The board provides options for resetting, exporting, importing, and locking BMS settings. To perform these actions, select the menu "Service → Settings":

In this section:

  • Download settings file – a link to save (export) a file with board settings to a PC;
  • Reset device settings – a link to reset board settings to default values;
  • Upload settings file – a form for loading (importing) the board settings from a settings file;
  • Lock/unlock settings – a form to lock or unlock the board settings:
    • Locked – a state of settings;
    • Password – a field with a password to protect settings from changing (optional);
    • Repeat password – a field to repeat the password (optional).

To lock the BMS settings, click on the “Lock” button. Locked settings cannot be changed. In addition to the prohibition on changing settings, the system calculates a checksum across the entire BMS configuration. When starting the BMS checks the checksum settings. If the checksum does not match the required value, then the “Settings error” is generated. At the same time, a critical error flag is generated and all relays open.

To unlock the BMS settings, click on the Unlock button.

Locking settings can be password protected.

Attention!
If the password is lost, the BMS settings can be unlocked only by the BMS manufacturer!

To reset the settings, select “Reset device settings”. This operation will not be performed when the BMS settings are locked.

To export settings, select “Download settings file”. In this case, a file with the name "settings.txt" will be downloaded from the board, in which all the parameters of the BMS Main 2.x board are written in text form.

To import the settings, click on the "Select a file" button, specify the previously saved "settings.txt" file and click on the "Upload" button. This operation will not be performed when the BMS settings are locked.

Attention!
To perform the export and import of settings, SD card must be inserted in the card slot!

Real-time clock is used for logging timestamps.

To set the current time and the time zone, select the menu "Service → Clock":

The line in DST start "Sunday, March, 2" means that the clock is switched to summer time at 02:00 on the last Sunday in March.
