I've got a 2-stop old Hydro unit that is floor level with the doors open. It will run up/down on INSP, but will not run up/down on auto.
Please see the attached prints.

Did you get it figured out today?
———————————————————-
Status of DOP, DO and PC in controller?
Safe Edge contact?
Door Board test/manual switch set incorrectly?
Operator Relays?
Stuck DOB?
Just a few ideas....

The print is hard to read, but it looks like you have to pick UDX to drop the DO relay. The UDX relay is picked with a direction, either up or dn. The common link in the direction circuit is, from what I can make out either LR or IR relay. take a close look at those associated contacts and relays. You should come up with a solution. Good Luck.
