- the safety chain 10 may have further electrical contacts which serve, for example, to monitor a brake of the elevator.
- the elevator device 1 can also be retrofitted in an existing elevator or in existing elevator systems.
- FIGS. 5 and 6 show two alternative embodiments of an elevator device. Substantially identical components, features and functions are basically numbered by the same reference numerals. In order to distinguish the exemplary embodiments, however, the letters "a" and "b" are added to the reference symbols of the exemplary embodiments in FIGS. 5 and 6. The following description is essentially limited to the differences from the exemplary embodiment in FIGS. 1 to 4, reference being made to the description of the exemplary embodiment in FIGS. 1 to 4 with regard to components, features and functions remaining the same.
- the elevator device 1 a shown in FIG. 5 comprises a test device 11 a with a control unit 44 a and a safety chain 10 a, wherein the control unit and the Safety chain preferably form part of the elevator control 45a of an elevator. Furthermore, the test device 11a comprises a hardware monitoring unit 16a with a detection unit 20a and a switching relay 70a with two switching contacts 70.1a, 70.2a. During operation of the elevator, a safety chain voltage is applied to the safety chain 10a via the control unit 44a of the elevator control 45a.
- a current flows through the safety chain 10a, which for example activates a safety relay 38a of the control unit 44a, which signals to the elevator control 45a that a transport of Persons and / or loads safely with the elevator is possible.
- the control unit 44a has a time measuring unit 74 which measures a time duration during which the current flows uninterruptedly through the safety chain 10a. If this time duration exceeds a certain value, then a trip unit 42a of the control unit 44a activates the hardware monitoring unit 16a and the switching relay 70a with the switch contacts 70.1a, 70.2a.
- the switch contacts 70.1a, 70.2a then disconnect the safety chain 10a from the control unit 44a and connect one end 76a of the safety chain 10a to an input 80a of the hardware monitoring unit 16a and another end 78a of the safety chain 10a to an output 82a of the hardware monitoring unit 16a.
- a voltage generated by a monitoring voltage source 84a present in the hardware monitoring unit 16a is applied to the safety chain 10a.
- a current measuring unit 30a and a voltage measuring unit 32a of the detection unit 20a form a resistance measuring unit 34a which determines a total resistance value of the safety chain 10a. This is done by the current measuring unit 30a measuring the current flow generated by the voltage source 84a, the resistance measuring unit 34a measuring the current during the measuring process
- Safety chain measured monitoring voltage and measures the detection unit from the measured current and the measured monitoring voltage, the current total resistance value of the safety chain. As described above in connection with FIG. 1, the determined total resistance is compared in a comparison unit 24a with a stored reference variable, whereupon optionally the comparison unit of an output unit 40a signals an inadmissibly high total resistance value. After detection of the total resistance value, preferably lasting less than 10 seconds, the switching relay disconnects the safety chain 10a from the detection unit 20a and places the safety chain back on the control circuit 44a of the elevator control 45a Safety chain voltage on. If the hardware monitoring unit 16a is activated due to the length of time during which the security chain is not interrupted, then a measurement of the total resistance value preferably takes place at night, since lift usage rarely takes place in this period.
- control unit 44a detects in another way that the elevator is unused and then initiates a disconnection of the safety chain 10a from the safety chain voltage and coupling to the monitoring voltage source of the hardware monitoring unit 16a.
- detection of the total resistance value 22 is limited to a fixed number of measurements per unit of time, for example, one measurement per day at a time at which the elevator is barely used according to experience.
- FIG. 6 shows a further exemplary embodiment of an elevator device 1b with a control unit 44b, safety chain 10b, and a hardware monitoring unit 16b with a detection unit 20b.
- the mode of action of the elevator device 1 b essentially corresponds to the mode of operation of the elevator device described in connection with FIGS. 1 and 2.
- the detection unit 20b here has a current measuring unit 30b, which is designed as an induction current measuring unit. If a current flows through the safety chain 10b, a current is induced in the current measuring unit 30b, by means of which the current measuring unit 30b calculates the current intensity of the current flowing through the safety chain 10b. Ends 76b, 78b of the safety chain 10b are conductively connected directly to the control unit 44b.
