Elevator And Method For Demonstrating Operation Of Elevator Safety System

Abstract: An elevator (100), comprising: an elevator car (10) adapted to transfer passengers and/or cargo between landing floors (30) in an elevator shaft (1); an elevator hoisting machinery (5) adapted to move the elevator car; an elevator controller (110) configured to control elevator operation in normal operation mode; and a safety system (120) configured to: receive safety information from a plurality of safety sensors (20), detect a safety-related problem based on safety information received from at least one of the safety sensors; wherein the elevator controller (110) is configured to execute a normal stop to make elevator car (10) to stop or to hold the car standstill in the elevator shaft (1); and wherein, in case a safety-related problem was detected, the safety system (120) is configured to execute a safety stop to bring the elevator to a safety state, which safety stop is configured to override operation of the elevator controller (110); wherein the elevator controller (110) is configured to: determine that one or more predetermined operational conditions for a safety stop demonstration test are fulfilled, and in response to the determination, deactivate said normal stop, to demonstrate operation of the safety stop. A method for demonstrating operation of an elevator safety system (120). Figure 2
