1. A car safety supervising unit for an elevator, the elevator including an elevator car displaceable within an elevator shaft, the car safety supervising unit comprising:
at least one sensor sensing car-related parameters and outputting corresponding car-related signals;
an I/O interface inputting input signals into the car safety supervising unit and outputting output signals to external devices;
a signal processing unit processing at least one of the car-related signals and the input signals and generating the output signals;
wherein the car safety supervising unit is adapted to operate in each one of an installation operation mode and a normal operation mode;
wherein, in the installation operation mode, the signal processing unit processes exclusively the car-related signals and generates the output signals based exclusively on the car-related signals; and
wherein, in the normal operation mode, the signal processing unit 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.
