BatteryProtect display meaning

A BatteryProtect 12/24V-100A is used as load shedding controlled by a VE.Bus BMS connected to a LiFePO4 Battery 12,8V/100Ah Smart. After a full charge of the battery we sailed off and after about 5Ah consumption (navigation instriuments + rudder control) the BatteryProtect has cut off showing a moving "C" on its 7 segment LED display.

What does this moving "C" mean?

Also, after some hours' rest (about 7 hours, while the system was switched off) is has resumed without intervention. Why?

Unfortunately the sailing conditions were harsh enough not to be able to check the fault at once, and when got back to the marina, the system was OK.

Any clue is welcome! Thank you in advance.

‘C’ indicates that it‘s in Lithium mode, which would be correct for your setup, although it doesn’t ‘move’ as such. The appearance of moving values is normally when there there’s been an issue, with an ‘E’ being followed by a number (e.g. E3 is undervoltage).
