Hello,
Was wondering if anyone could improve on my "first up" circuit. I'm sure there is a way but cant quite get it!
What I've got is 4 switches pulling in a contactor. I wish to find which switch drops out first. I've done a program in statment list but was trying to do it hard wired as well.
The attachment shows what I have. First cicuit is the original. The rest is the wiring I need to capture the switch dropping out.
Is it possible to do it with just 4 relays rather than 8? I must be missing something!
cheers
