The guy on the second shift got to messing around with the parameters on a feeder one time trying to troubleshoot a problem. He changed one of them and then went home for the evening. I spent the better part of the getting the thing working and couldn't figure out how it got changed in the first place until he showed up the next day.
I printed this out and left it on the workbench for him the following day. He thought it was German and tried to translate it using one of those translation apps on his phone.
Too funny...I thought everyone had seen this one before...
Bill in OKC too
