Yes RELU is level up command or fault.
If all else fails like valve adjustments (F/S, bypass or LU adjuster on Maxton) and you only observe this failure at the first floor, and assuming this is the terminal floor, change the parking assignment to the second landing. I had one out of two roped hydros that only one would fail overnight on RELU. We caught it failing on a security camera…at the terminal landing.
Changed the parking for that car and problem solved. Just an idea.
Hopefully EE got you what you need.
