We have a group of 3 TAC 32T's that are having a dispatching issue. There can be 1 or even 2 cars sitting at a floor, you give it a hall call at that floor and it will bring a car from a different floor. All 3 elevators are affected, happens at every floor, sometimes it will dispatch the car that is sitting at that floor but most of the time it brings one from another floor. There are no hall node boards, hall calls come upstairs into CNA boards in controllers. We have checked the inter-group Channel resistance=61.5 ohms. no group faults. Has anyone experienced this?
