ELEVATOR SAFETY SYSTEM

The invention is about an elevator safety system, comprising an electronic safety controller (20) running a software comprising a monitoring mode for monitoring the position of an elevator car (3) within a hoistway (4). The system comprises a position measurement device (2; 21) for measuring said elevator car position. Further, there are limit position identification markers (1C) being installed in the hoistway (4) for defining a starting point of a final movement zone in which the car is still allowed to run in direction to the outermost ends of the hoistway. However, as soon as the end of the final limit zone is reached by the car, an emergency stop is triggered. According to the invention, the position data for the final limit zone are laid down in a memory of the safety controller as parametrized data for being able to adjust them if so needed. Therewith, it can be avoided that the hardware components in the shaft have to be replaced.
