the logic will detect a if a part has been ejected from a stamping press. the program monitors a N.O. switch that is mounted on a cam which is part of the brake assembly on the press. when the cam flywheel returns to top dead center and no part was detected, a jam is signaled.
1. the AUTO/MAN switch is set to AUTO, voltage is applied to I:1.0/01, and the process will start.
2. the cam flywheel starts at top dead center and the switch, I:1.0/00 is in the normal position.
3. as the cam flywheel begins to turn, the switch, I:.0/00 is actuated and will remain actuated until the cma flywheel returns to top dead center.
4. after the dies separate,an ejector pin pushes the stamped part down a discharge chute and past a normally open sensor, I:1.0/02, that detects the part. A detected part turns on Binary output, B3/1 until the cam cycle is done.
5. when the cam flywheel is back at top dead center and if no part has been detected, the binary output, B3/3, is turned on. This is the signal to disengage the flywheel and stop press motion. Binary output, B3/3 is turned off when the AUTO/MAN switch, I:1.0/1 is in the MAN position.
6. to reset the jam, the AUTO/MAN switch must be returned to MAN, no voltage at I:1.0/01. when returned to AUTO, the process restarts.
7. B3/3 must be set when no part has been detected and the flywheel is back at top dead center.

I'm having problems determining what the auto/man switch turns on. This is in RSLOGIX 500. can someone please help solve this or the whole thing, please post the .rss into a zip file or send it to my email. I have other questions but the first rung is confusing.
