Be in charge.

Super B.

6.4.  Status and control

The state of the BCI can be controlled by the Be in Charge software. The Be in Charge 
software can read and set the state of the BCI. The state in which the BCI is, is indicated by 
the indication bar as depicted in Figure 28.

Figure 28. BCI Control tab

The state of the BCI can be manually controlled by using the buttons underneath the BCI 
Control tab. The reset button can be used to reset the BCI when the BIB and or a Li-ion 
battery is in error state. 

More information about the different state and the corresponding behaviour can be found in 
chapter 3.4.3.
