Definitions

• the invention relates to a device, a method and an operating unit for activating an operating unit of an elevator installation.
• Lift systems must be checked or tested after installation or extensive repair work.
• the installation of the elevator installation commissioning is required in which many parameters must be set and a comprehensive and detailed examination of the individual components of the elevator system is performed.
• a number of steps must be taken after installation of all mechanical parts and all electrical components to bring the system into a condition that will allow normal operation.
• the necessary steps of a commissioning include a review of the mechanical and electrical requirements, activation of the electrical components, a review of the drive, the configuration of shaft information to determine the position and speed of the elevator car and the configuration of an elevator control and a device for Measurement of cabin load and communication interfaces.
• a good example of such a method is known from EP 0366097 A1.
• Another check is to test whether the elevator car stops on a floor when the lift was previously called on that floor by means of a control panel.
• the lift mechanic must go from floor to floor, operate the operating unit and check that the elevator car is in proper condition.
• this review is associated with great physical strain.
• such a manual inspection takes a great deal of time, unnecessarily increasing the cost of installation.
• An object of the invention is to propose a possibility for a cost-effective and efficient inspection of an elevator installation.
• the invention will be described with reference to the independent claims. Continuations are given in the dependent claims.
• a core of the invention is that for activating an operating unit of an elevator installation in a multi-storey building, the switching unit is bridged by an elevator operating unit.
• the elevator installation has at least one elevator car, which moves along a vertical car lane between the floors, a control unit and on floors, on which the elevator car holds, at least one control unit connected to the control unit via a communication network.
• Activation of the operating unit can thus be done centrally by a control unit for test purposes. But even for emergency scenarios, such an activation might be necessary.
• the activation of the control unit for the purpose of a normal elevator ride happens.
• the at least one operating unit contains at least one switching element z.
• a push button a rocker switch, a touch-sensitive sensor, a capacitive sensor, an inductive sensor, etc.

• the control unit any type of control unit can be used. So z. B. operating units with inductive, capacitive, electronic, mechanical and electrical switching elements are used.
• the circuit is constructed so that it allows a bridging of the switch unit and may have at least one transistor.
• the base of the transistor is connected to the output of the control unit of the operating unit and the emitter to ground.
• the collector of the transistor is connected via a capacitor connected in series with the switching element of the operating unit.
• a mechanical or electrical or electronic switch is the basis of Transistor connected to the output of the control unit of the control unit, the collector to the switching element and the emitter to ground.
• any kind of communication network such as a packet-switched communication network, a circuit-switching communication network, a radio network, a bus system, etc. may be used.
• the control unit of the elevator installation sends a signal to the at least one operating unit, then the circuit is activated.
• the activation of the circuit can also take place simultaneously with each operating unit of the elevator installation.
• the control unit transmits an activation signal simultaneously to all operating units of the elevator installation. Usually such a procedure is called a group call or broadcast.
• the signal may be an analog signal, a digital signal, a surge, a signaling message, etc. In essence, the nature of the signal depends on the processing capabilities of the control unit.
• the signal for activating the circuit is received by the control unit and activates the circuit. This bridges the switch unit of the control unit.
• the activation of the circuit has the consequence that the pressing of the switching element is simulated.
• the resulting from the simulated pressing of the switching element signal, z. As a date, a surge, an analog signal, a digital signal, etc. is detected or received by the switching unit and to the
• Control unit forwarded. Under certain circumstances, the control unit evaluates the signal and forwards the pressing of the switching element to the control unit for further processing.
• the signal received by the control unit is intended to trigger the event that the elevator car on the floor on which the control element of the control unit was simulated pressed down, stops on the floor and opens the doors, so that a supposed (there is a simulated

• the elevator car AK likewise has operating and control units which are connected to the control unit SE via a communication network KN. However, these are not shown for reasons of clarity. Also, the drive and other units of the elevator system are not shown for the same reason.
• a signal for activating the bridging of the switch unit 3 of the at least one operating unit 1 is sent by the control unit SE to at least one operating unit 1.
• the control unit 4 of the operating unit 1 activates the bridging of the switching unit 3 and thus the pressing of the switching element 2 is simulated.
• the simulated pressing of the switching element 2 generates a signal which is forwarded via the switch unit 3 to the control unit 4.
• the control unit 4 sends the signal that the switching element (simulated) has been pressed to the control unit SE.
• the control unit SE triggers on the basis of the received signal, the event that the elevator car on the floor SW on which the switching element 2 of the control unit 1 was simulated pressed to move, stop on the floor SW and open the doors, so a supposed (There is only a simulated pressing of the operating unit) Users of the elevator system could or could do an elevator ride. According to the invention, this procedure is used to check whether the elevator installation is correctly configured and proper operation is ensured.
• FIG. 2 shows the schematic structure of a capacitive switch.
• capacitive switches or capacitive sensors are based on the principle that two plates form an electrical capacitor, one of which is displaced or deformed by the effect to be measured. As a result, the plate spacing and thus the electrically measurable capacitance change.
