Hi,
We are thinking of implementing a light to our safety system that indicates that a machine is in a ceratian more dangerous state then normal.
Talking to a safety specialist he said (but didn't know how to) that maybe I could have an indication if the light was broken. For example a relay is activated when the indication light is broken.
I can't figure out how to achieve this. Also I don't know HOW the indication light behave if it's broken. Does it still have the same internal resistance? Is it lower, higher or zero. It seems that he took this out of thin air without knowing there is a solution for it.
