I have a dmc in a bank that has had the top floor car and hall calls disabled for over 1 year because the floor was vacant. The calls were disabled by disconnecting wires at the buttons. Today the customer requested the calls be enabled again so the route mechanic reconnected the wires and attempted to run the elevator to the top landing by car and hall calls. It runs up to about 12" below floor level and shuts down. We have a world tool but it has failed so we have no way to check the faults. It shuts down at the same spot every time. We checked the switches and wiring on the switch tree. We have to cycle the power off and on to reset. Any ideas? I have a new tool on the way but in the mean time the customer can't take the elevator to the top floor.
