I am using Siemens 840d power line system. when I switch ON the machine its working normally but after 10 or 15 min its automatically getting switched OFF. If I switch ON again its getting ON normally again its happened same like that after 10 to 15 min. (Note; display getting proper switch OFF when fault occurred). I am awaiting for your reply.

Hello,

Is the screen getting dark or 840D system getting OFF? Have you checked/confirmed?

Is it with PCU20 or with PCU50? Have you checked 24 V DC supply? Do you observed any dip in supply?
