ECN Forum Forums Technical Discussion Electrical Theory and Applications Help... Virgil's baffled by control work again...

This will take a while to load... Sorry to rob your bandwidth there, Bill, but as they say, a picture is worth a thousand Q's, or something like that...

This first drawing basically shows what I've got:



Here's the real thing, it will be replaced with a PVC dust proof box and new controls as soon as I can figure out how it works:



Here's the original schematic:



Here's how I think it would be hooked up according to above schematic:



Here's one of the limit switches:


I haven't seen the motor, gate, or any other parts.

The more I study it, the less it makes sense.

In a nutshell, the crowd gates push the cows towards the milk parlor door, stop when it hits a cow, waits a few minutes and cycles again. There doesn't seam to be a reverse to reset the whole works, I guess you have to move the gates back by hand?

The schematic given just doesn't make sense to me... Especially how the timer controls, and the connection between the timer NC and the relay NO, seams like it'll just be energized from opposite directions and stops, depending on the relay position and timer.. Am I just goofy?

Any help at all is greatly appreciated.

Hey, if y'all say it'll work just fine like that, I'll go for it and chalk my misunderstading up due to ignorance...
