Hello

I have the old machine Weiler 120 with Sinumerik 3T system and the power source module is dead. I have one for change , but the problem is with changing the module - system will be erased when I do that change (battery for backup is in the module). Please, Do somebody have an idea how to do it and do not to erase the system? Somebody tells me that I can support the NC data with external battery 5V but I don´t know where to connect it.

Thanks for reply.

 I made circle on your picture. But I think you still have trouble. when you removed the power supply module --outside feeding will be removed . you can search you have good data Back up, which should be done whne machine in good condition .

I remember the file name like %TE1 and %TE2,

Hello

Photo of the system attached.

 I really don't know what you found. 3 system was more than 40 years. I last time dealing with it was in 2009.

There are some pins on RAM module 03260, named "RAM - Batt. + - ". (I made the circle around it) Is it possible that those pins are for that reason (to support memory with external battery 5V)? 

I have another 3T system and made inspection of that card - there is some diode there for blocking the voltage - I don´t know, maybe it is the right connector?

Thanks for the reply
