Dear all,
I have a TRUMPF Trupunch 3000 machine since 2010. I have a problem every times the battery 12V DC inside the Cabinet of the machine is empty. After replace the new one I get always error PLC BATTERY IS FAIRLURE during starting the machine and it can not working anymore. On the operator panel it shows that I must call service's man to RESET the machine. I try to find how to reset the machine but I founded nothing. In such as case I must call Trumpf's service to solve this problem. After done, one Guy come and do some tasks very quick on Operator panel then the machine is ready for working again. I asked the Guy about the way to RESET this error, but he did not tell me. I think this problem can be very easy to solve every replacing PLC battery, but why service's guy don't show me. It make me really crazy every times I meet this problem.
Can anyone, who know about the way can solve my problem please help me.

Thanks in advanced,
