I checked the Control board and it had no dirt or moist on it, there was nothing that could lead to a short circuit.
So I replaced the Control board with an other one which I had and everything worked fine.

I think the solution will be to perform a control board recovery as mikeywith said.

I'll keep you updated 

Okay! That's great! Thank you really much.  

They are Antminer S7

I don't use any script to shut them down. I just cut the power but they reset anyways.

Hello everyone!

I am currently working on an automated BTCitcoin mining farm.
As the power consume is pretty high I have built an automated system which will automatically cut the power of the miners when the batteries are low.
I used some smart plugs to do this. Let me know if there is a better solution than just cutting the power of the Antminers.

But back to my main question:
Every time I power the Antminers back on after auto shutdown, the Miner Configuration has been reset.
Is there any way to prevent that from happening?

Thanks in advance
