Abstract (en)
[origin: EP1792864A1] In an elevator apparatus, an electronic safety apparatus detects abnormality of an elevator based on a detection signal from a sensor and outputs an instruction signal for shifting the elevator to a safe state. The electronic safety apparatus can detect abnormality of the electronic safety apparatus itself. When abnormality of the electronic safety apparatus itself is detected, the electronic safety apparatus also outputs the instruction signal for shifting the elevator to the safe state.
