Abstract (en)
The present invention relates to a fault detection method for a lift system (100), said method comprising the steps of:x - detecting at least one car movement parameter of said car (101) over time;a1 - analyzing changes of the at least one car movement parameter in a second threshold time interval (T2);b1 - when the at least one car movement parameter analyzed in step a1 has not changed in said second threshold time interval (T2), sending a second signal to move the car to a second floor position;a2 - following step b1, analyzing changes of the at least one car movement parameter in a third threshold time interval (T3), said third threshold time interval (T3) being successive to said second threshold time interval (T2);b2 - when the at least one car movement parameter analyzed in step a2 has not changed for said third threshold time interval (T3), sending a fault signal to signal a fault of said lift system (100).
