Wizards,
I have been gone from my plant for a while and upon returning I have two, 480vac-24vdc power supplies on my desk with DEAD written on the box.
Upon investigation, it turns out that one of the two power supplies in this machine have died.
When the PS dies, they notices that fuse leg 1 is also blown but the other two are just fine.
They replace all 3 fuses and the PS, everything works out great for an undetermined amount of time.
We are not in production on a daily basis atm and most of the time the machine just sits idle. When we do run the machine, everything works out just fine, we just randomly find a dead power supply in it in the morning when we show up.
A line conditioner was asked about, but I am reluctant to add more things to this machine without having a better idea as to what the root cause is.
