forcing the classic to resting externally

[ulisse10000]

Hello boys
I am building a BMS system to control each battery cell of my batteries bank, I would like to force the classic to resting or to OFF mode in case the BMS is detecting some issue on one cell (i.e. overchargin or short circuits) ,some one can help me to found a way to force the classic to resting or to off with an external trigger signal?
Better possibility will be to be able to control the classic with a 5V signal directly sent by the micro processor.
I see that could be possible with AUX 2 configured as input there are other possibilities ?
many thanks for your help

There are 2 ways to do this:

1- Send Aux2 a logic signal input as noted, This can be a high or low signal depending on the mode you select on the classic. IE if the Aux2 + goes to ground it goes to resting in one mode or if Aux2 + goes above I believe 7 volts it goes to resting

2- Command it via modbus to stop charging and go to mode off or resting, this would require the BMS to be able to talk modbus to the classic some how
