Otis 211 hydro intermittent STLU fault - 05/28/22 02:55 PM

Hello all, have a otis 211 hydro 3 stop and intermittently shutting down on "stlu".
I have verified upper limits and magnets on tape.

I can not figure this one out. It may run for a month and then I will have this fault a couple times over a week and then go away for a while before returning.
Any ideas?
