This 330a is stuck in AST mode. I can run the elevator on inspection but it will return back to ast every time as soon as I switch it to automotic. When I reset the elevator controlls it also goes back into ast mode before it even tries to run. I checked the emergency terminal limits and everything is ok. The faults are a 107 pit oil switch, which this elevator does not have and a 1209, missing node. I checked the nodes on the smlcd and they all test out ok. Does anyone have any ideas why this elevator will not come out of ast mode?
