We have some old lines that have many door and cover switches integrated as part of the estop circuit. Some of these circuits have 60+ devices Limit switches,door switches,estop buttons,etc.
I have one that has been giving me a fit the last few days as it will intermittently stop the line but the fault does not stay and i really hate to start jumping out safey switches in a large fashion but this is costing a lot of down time which is a lot of money some of thes come back to a common terminal strip but many go straight from one device to another.
Is there any test equipment with multiple channels that can detect which device is lost first when they are all on a common feed?
Any other ideas on the best way to find this?
