Abstract (en)
[origin: US2005098390A1] An elevator installation with an elevator car moveable in an elevator hoistway by means a drive unit is controlled by a control unit. Sensors monitor the status of the elevator installation and are each connected via an assigned bus node to a data bus and thereby connected to the control unit. In order to obtain improved operational safety and improved availability, each sensor controls a voltage supply of the associated bus node.
