Richard - always a good idea to have the LS set correctly. But, back when I was designing using a LS to signal normal operational positions was common, but we were not allowed to use one as the only means to prevent equipment damage. Limits switches will fail eventually. So what happens then? We designed the power of the mover ( motor or hydraulics ) to be less than the structure could stand. In other words, it was okey to stall out the motor and trip an internal thermal breaker, blow a fuse, trip a breaker etc., but not okay to break a weld. From way too far away to make a good judgement I have to wonder about the design or the weld.
