Abstract: An illustrative elevator system includes an elevator car, a machine including a motor that provides a motive force for moving the elevator car along a travel path and a brake that resists movement of the elevator car, and a brake controller. The brake controller is configured to determine when the elevator car is within a selected range of at least one end of the travel path. The brake controller inhibits a delay in application of the brake when the elevator car is within the selected range and permits a delay in application of the brake when the elevator car is outside of the selected range.

Abstract: A testing arrangement (36) for testing the operability of at least one safety sensor (21, 22, 23, 26, 28) connected to the safety chain (30) of an elevator system (1), the testing arrangement (36) comprises: at least one test circuit (34) for testing the operability of the at least one safety sensor (21, 22, 23, 26, 28); and at least one testing relay (32, 33). The testing relay (32, 33) is switchable between an operational position and a test position and it is configured for electrically connecting the at least one safety sensor (21, 22, 23, 26, 28) to the safety chain (30) in the operational position and for electrically connecting the at least one safety sensor (21, 22, 23, 26, 28) to the test circuit (34) in the test position.
