Interlock, TRUE or FALSE?



Hello all,

I’d like ask your for an opinion, please. When there is a device and it has certain conditions to work or move and you have created status for that, how do you call it and is status true or false when the device is alloved to move?

I know that this might be a stupid question for someone but I ask this in common level to find out which one is more common. I’m used to do one way, which I think is the best and most logical way but there is another way of thinking, too.

Thank you in advence.
