I know you probably did this but...When that happens... Both units sit with doors open or just one unit? Are hall calls latched but the car won't go or are completely deactivated? I was thinking in parameter 5.4.4.18 (DOORS TO OPEN IF PARKED). Is this parameter set to open doors? If so a issue with the closing sequence can cause problems. Is this a problem that have always been noticed? Usually new Management will bring up problems but in reality it's been going on for years.
