Abstract
A method of operating an elevator or escalator system is provided. The method includes alerting a mechanic of a shutdown of a vehicle of the elevator or escalator system and providing data indicative of an occupancy condition of the vehicle to the mechanic so that the mechanic can execute, in any order, a verification of a no-occupancy condition, a switch of a mode of operation of the elevator or escalator system to a recovery mode and an inspection for faults. The method further includes initiating an overspeed (OS) switch reset routine in an event the mechanic confirms that an actuation of the OS switch is an exclusive cause of the shutdown and remotely triggers the OS switch reset routine accordingly.
