US 11,072,515 B2 · Automated elevator maintenance mode initiation

Abstract

An illustrative example elevator system includes at least one elevator car that is moveable along a hoistway. An elevator controller is configured to respond to a communication from a portable device indicating a desire for the at least one elevator car to be placed in a maintenance mode and indicating a location of desired hoistway access. The controller automatically moves the elevator car to a determined positon based on the communication. That position corresponds to the location of the desired hoistway access. The controller performs at least one automated procedure to place the elevator car in the maintenance mode. The controller provides an indication to the portable device that the elevator car is in the determined position and that the automated procedure has been completed.
