48 +The BMS Main 3 device can check if the charging current exceeds the estimated limit based on the [[Charge map>>url:https://docs.movicomelectric.com/bin/view/Battery%20management%20systems/BMS%20Main%203/3.%20Configuration/3.3%20Control/#HChargemap]]. If current exceeds the calculated limit more than configured difference, "Current limit" error is generated.

50 +Current difference is separated to two regions by the threshold value. Maximum current in Region 1 is calculated by the absolute difference, in Region 2 – by the relative difference.
51 +
52 +To change the overcurrent protection of the battery, select the "Protections → Charge current limit" section:

57 +* Enable – a flag to enable the protection;
58 +* Threshold to switch from Region 1 to Region 2 – a current value at which current excess calculation will be switched from absolute to relative difference, A;
59 +* Region 1: Current difference – a value of maximum absolute current diffr, A;
60 +* Region 2: Current difference – a value of maximum relative current excess, A;
61 +* Delay before setting the error, millisecond;
62 +* Delay before clearing the error, second;
63 +* Lock – a flag to block the error until the device is restarted.
