摘要
A car safety supervising unit (SSU) (35) for an elevator (1) comprising an elevator car (3) displaceable within an elevator shaft (7) is proposed. The car SSU (35) comprises at least one sensor (17, 19, 21) for sensing car-related parameters and outputting corresponding car-related signals, an I/O interface (41) for inputting input signals into the car SSU (35) and for outputting output signals to external devices (31, 37) and a signal processing unit (39) for processing at least one of the car-related signals and the input signals and for generating the output signals. Therein, the car SSU (35) is adapted to operate in each one of an installation operation mode and a normal operation mode. In the installation operation mode, the signal processing unit (39) processes exclusively the car-related signals and generates the output signals based exclusively on the car-related signals. In the normal operation mode, the signal processing unit (39) processes both the car-related signals and the input signals and generates the output signals based on both the car- related signals and the input signals. Accordingly, the car SSU (35) may be adapted for accomplishing basic safety functions for safely operating the elevator (1) during an installation phase in which e.g. only a limited number of sensors (17, 19, 21) is available in an autonomous manner.
