摘要
elevator safety supervisory body (s) (33) having - a cabin safety supervisory unit (ssu) (35) which controls the functions of the cabin safety components (30, 31) and having a cabin sensor ( 17, 19, 21) for detecting cabin parameters, - a main ssu (37) which controls the functions of well safety components (14, 16) and has a well sensor (23, 25) for detecting parameters from the well and a data link (38) for transmitting signal data between the cabin ssu and the main ssu. cabin ssu and main ssu detect a failure between cabin ssu and main ssu and to detect a failure in signal data transmission via data link and to switch from a normal operating mode to a failure operation. In fault operation mode, the cabin ssu and main ssu operate autonomously and the cabin ssu controls the functions of the cabin safety components based on information derived from the detected cab parameters but excluding the well parameters detected by the sensors. ssu main well and master ssu controls the functions of well safety components based on information derived from the detected well parameters, but excluding the cab parameters detected by the ssu cabin sensors.
