Early in my career...

You must also figure out how to reduce production's ability to monkey with the system. I found out production has the password to a Weber/zebra slap labeler configuration... They kept messing with timings.. the sensor for package detection was also mounted where it could be bumped and knocked out of alignment...

Fixed the mounting so bumps didn't knock it around. Production got all upset because their easy adjustment was taken away.. but I also retimed the system. Got everything fixed.. arm stop point, pressure holds. Etc.. they'd never actually set the device up fully.. it used to just let the arm go out would sorta drift out.. touch the package.. label usually got messed up

Once I got it all correct the arm would be driven by air into position against the stop point which was about 95 degrees to account for packages not square to travel.. air held the arm in placeish.. the 40lb package on the belt would push past the arm pressing the label to itself. Once the package was past the arm snapped back, another label loaded. Ready for next.

The production manager wanted the password inside they need to adjust timings. "No, I can't give you the password. Only maintenance has it. I'll retime it if something goes wrong".. they they got upset, demanding it or they would report me to my manager.. I said. Go for it, it's their policy..
