So, just got a LRV2000 on full service. 1982, round rail job. Yup Otis had them. Got a problem. Did an annual pressure and hydro test. LOT 130 sec's. All good, but sometimes put in a 1 floor run doors open then close. LOT (SP) relay fires car does not return to lowest landing open then close doors. Remove valve wire from UMSO, put calls in for 2nd and 3rd landing, car runs on leveling to both floors, no LOT. Pull the hook with doors open on 3rd landing to put valve wire back on. Empty Building. Put hook in SP fires 'right now'car returns doors cycle. End of day, go home confused. Got prints in front of me, can't see the senario? Bad TM8 board?
