Abstract (en)
[origin: WO2022136635A1] The invention relates to an elevator (2) comprising a safety control unit (12), the safety control unit (12) having an input (14) for selecting the mode of operation, and the safety control unit (12) being designed to differentiate at least a first input signal and a second input signal at the input (14). The elevator (2) also comprises a main switch device (16) having a switch (18), the main switch device (16) being accessible from outside the shaft (4), the main switch device (16) and the safety control unit (12) being connected, and it being possible to switch the switch (18) from at least a first state (20) into a second state (22). The safety control unit (12) is configured such that it operates in a first mode of operation when the switch (18) is switched into the first state (20), in a second mode of operation when the switch (18) is switched into the second state (22) and the safety control unit (12) detects the first input signal at the input (14), and in a third mode of operation when the switch (18) is switched into the second state (22) and the safety control unit (12) detects the second input signal at the input (14).
