Hello,

i have 2 SEPLOS MASON135. I have the problem after about 1 Week i loose periodic the RS485 connection to both BMS.
Only restet the BMS help to get any connection to the BMS.
On this restet i see a very stange behavior.

I shut down the Master and than the Slave. And as you can see the Slave automatic switch on... and then i shut down the Slave again and both cam back :-(
I can not shut down both. This is very strange. What if i had to emergence shut down the packs?

Do you know what i can do to shut me system down?
What can i do not to loose my connection?

Have an nice day
Martin
