This was my first guess, although I do not have explicitly experience in life-or-death type of control systems. In such systems, does it make sense to have more than two states? Something like "open", "unknown but not open", "unknown but not closed", "unknown", "closed"? (Assuming that you have enough limit switches.)

- idiotsecant 3y agoThat's exactly what you do. In all systems you should have two switches, and you annunciate on / off / travelling / error to the operator. Often you inherit something that doesn't have that. In anything that really matters you have a continuous position transmitter instead of switches so your state is more obvious. In safety systems you might have 2 or 3 of those transmitters so you can have a backup or a vote
- bmitc 3y agoThank you! Do you have any good references for voting systems? I've always wanted to learn more about those.
