Seco 2000, did you ever resolve this issue. We’ve been having a flrp issue on a 211 as well. Replaced magnets, selector board and cpu. Checked all wiring and traveling cable, magnet placement, and valve adjustment. Otis has been out twice and they weren’t able to fix it. The last thing we did was replace valve because according to tech on site on one occasion he was on top with helper giving it calls and saw it overshoot and shutdown with flrp. I thought maybe bypass was intermittently hanging up so we replaced valve and that didn’t help either. And I would think if that was the issue it would just level back down and keep going but we replaced valve anyway (uc2). It will run for almost 24 hours sometimes with no issues. My next step is to move all traveling cables having to do with selector to spares and then trying another selector board( maybe bad from factory?) .
