- the electromechanical switches have a number of approximately 520,000 circuits per year. This number is so high that the electromechanical switches become the main limiting factor for the reliability of the door contacts bridging. Due to the high number of circuits and the high requirements, the bridging of the door contacts is classified as a so-called high-demand safety function.
- the IEC 61508 standard defines high-demand safety functions as functions that, on average, switch over more than once a year during trouble-free normal operation of the elevator system, while low-demand safety functions designate such functions as are provided only for emergencies of the elevator system or only for an emergency operation of the elevator system, in which there is a fault and switch on average less frequently than once a year.

- the executing elements of this low-demand security feature have no effect on this
- the safety function which operates in continuous mode, always keeps the system to be monitored in its normal safe state.
- the elements of this high-demand Safety function constantly monitor the system to be monitored. A failure of the elements of this (high-demand)
- Safety function leads directly to a hazard, if no other safety-related systems or external
- Requirement rate is not more than once a year and is not greater than twice the frequency of the re-examination.

- Semiconductor switches are used according to the invention for a high-demand safety function, for example for the
- Electromechanical relay circuit - or at least parts thereof - according to the invention used in the case of a short circuit of one or both semiconductor switches to open the safety circuit.
- the monitoring of the semiconductor switch is carried out according to the invention by means of a monitoring circuit which is processor-controlled.

Circuit or test circuit by taking a voltage measurement at one input and one output of the MOSFET, separately for each channel. If one or both of the MOSFETs should be defective (which in most cases means short circuits for such switches), the respective processor will detect this condition and open the ETSL relay contact (s). Another advantage is thus that even both MOSFETs can be defective at the same time; that way the
- electromechanical safety relay or its contacts is bypassed.
- MOSFETs are normally always closed when the doors are open. Consequently, it is provided that the respective processor opens the MOSFET briefly at a regular interval of a few seconds in order to check the voltage drop across the MOSFET without the safety relay of the MOSFET
