Had some lasers set up on a 3pin, e-stop chain. The last laser did not react to the estop being hit. The run was going around a lot of other energized cables.
Are estops NO or NC normally closed? I thought they were usually closed, and the mushroom button would break the circuit when hit. Is it possible that laser somehow ended up being in an energized circuit?
I want to learn more about Estops, any suggestions for reading? I keep accidently coming upon other e stop like machinery
