Ok, so we were finally able to run a successful ADON learn and perform a shaft setup, and are no longer logging the 0026 fault. Instead, we keep logging 0071 (30 door zone missing), and no other faults. Every time the car is turned to automatic, it will travel to +/- 1/8 in. of floor level with no door operation. Checked all magnet positions and it appears to be good. Nothing in the hoistway has been touched while we've been working through these issues which is why this fault seems bizarre. CPU is showing 61:U and 61:N on along with 30 like my troubleshooting guide suggests. Don't know what else to try. Please help!
