Definitions

  • the present invention relates to a safety switching device for safely switching off an electrical load, in particular in an automated system, with at least one input for connecting a signaling device, with an evaluation and control unit, and with at least one switching element, which can be controlled by the evaluation and control unit is to interrupt a power supply path to the consumer, wherein the evaluation and control unit is adapted to functional tests at defined times perform to check a switching function of the at least one switching element.
  • Such a safety switching device is for example off DE 103 25 363 A1 known.
  • Safety switching devices are used to completely or partially shut down a technical system or a technical device, if this is necessary in order to avoid, for example, a hazard for operating personnel of the system or the device.
  • the safety switching devices have on the input side one or more connections for connecting one or more signaling devices, such as emergency stop buttons, safety door switches or photoelectric sensors.
  • the safety switching devices On the output side, the safety switching devices have at least one switching element with the aid of which a power supply path to the system or the device can be interrupted.
  • the evaluation and control unit is typically used to monitor the entire safety circuit including the connected signaling devices and possibly trigger a safety shutdown.
  • a safety switching device must still be able to switch off the system or the device if the output-side switching element of the safety switching device fails.
  • the contacts can be welded so that the relay can no longer be opened.
  • a transistor can alloy and thereby cause a short circuit, which prevents interruption of the power supply path to the consumer.
  • safety switching devices are generally constructed in a multi-channel-redundant manner, so that, for example, in the event of failure of a switching element, a redundant switching element arranged in series can interrupt the power supply path.
  • a redundant implementation in itself does not guarantee absolute error safety if the functionality of the individual channels is not regularly tested.
  • the aforementioned DE 103 25 363 A1 discloses a safety switching device having an evaluation and control unit (referred to therein as a signal processing part), which performs regular shutdown tests in operation to check whether the output side switching elements are still able to interrupt the power supply path to the consumer.
  • the evaluation and control unit has a two-channel redundant design to control any errors in the signal processing part of the safety switching device.
  • Another example of a two-channel redundant safety switching device is off DE 100 11 211 A1 known. Also in this case, the evaluation and control unit, which evaluates the input-side signaling devices and monitors and controls the switching elements, built two-channel redundant.
  • the two known safety switching devices are typical examples of implementations that meet the requirements of category 3 and even category 4 of the European standard EN 954-1 or comparable safety requirements according to ISO 13849-1 or IEC 61508.
  • the continuous redundant structure of the known safety switching devices is complicated and expensive.
  • PNOZ® X1 offers an emergency stop switchgear which has redundant (in series with each other) relay contacts on the output side in order to interrupt the power supply path to a consumer.
  • PNOZ® X1 is single-channel and has no special diagnostic options. Therefore, the PNOZ® X1 is approved without additional measures only for applications up to safety category 2 of EN 954-1.
  • this object is achieved by a safety switching device of the type mentioned, in which the at least one input for connecting the signaling device is also designed as an input for supplying a supply voltage, which is required for the operation of the at least one switching element.
  • the new safety switching device is thus characterized by the fact that the input for connecting the signaling device at the same time is also the input for supplying the supply voltage, which is required for the operation of the at least one switching element.
  • a signaling device is thus connected to the new safety switching device, that with the operation of the signaling device automatically the supply voltage for the at least one switching element is interrupted.
  • This is particularly easy to implement for signaling devices having one or more ⁇ ffneruttone that are opened upon actuation of the signaling device.
  • the invention is not limited to this and can be realized, for example, for signaling devices that provide a non-floating output signal.
  • the information (signaling signal from the signaling device) and the energy for the operation of the at least one switching element run simultaneously and in the same way.
  • the elimination of the supply voltage for the at least one switching element is identical to the information that a security request is present.
  • the supply voltage for the output-side switching elements is performed separately from the supply voltage for the output-side switching element in some conventional safety switching devices that meet higher safety categories. Since the information (signal from the annunciator) and the energy are then separated, relatively complex evaluation and control units are required to ensure an interruption of the power supply path to the consumer, as soon as the corresponding information (notification signal from the annunciator) is present. Since the evaluation of the message signal is a safety-critical task, the evaluation and control units of the known safety switching devices typically multi-channel redundant design. This effort is not required in the new safety switching device, which can therefore be realized significantly cheaper.
  • the new safety switching device has an evaluation and control unit, which is designed to perform functional tests in order to monitor the switching function of the at least one switching element.
  • the at least one input is also designed to supply a supply voltage, which is required for the operation of the evaluation and control unit.
  • the safety switching device includes a decoupling network, which is designed to decouple the supply voltage for the at least one switching element and the supply voltage for the evaluation and control unit from each other.
  • the decoupling network includes a first timer to delay the supply voltage for the at least one switching element relative to the supply voltage for the evaluation and control unit.
  • the supply voltages for the at least one switching element and the evaluation and control unit are not only decoupled from each other in terms of circuitry, but also separated from one another in terms of time. Since the evaluation and control unit receives its supply voltage according to this embodiment "earlier" than the at least one switching element, it is ensured that the evaluation and control unit can complete internal self-tests before it controls the at least one switching element. A faulty release of the power supply path to the consumer is thereby even better avoided.
  • the safety switching device includes a reset circuit, which is designed to bring the evaluation and control unit at each renewed return of the supply voltage in a defined start state.
  • This embodiment facilitates the realization of the evaluation and control unit with a (single-channel) microcontroller, microprocessor or the like.
  • a reset which is forced every time power is restored, ensures that the evaluation and control unit always starts from the same defined starting position. This ensures that the evaluation and control unit completes its self-tests each time before the power supply path to the Consumer is closed. Due to this, the evaluation and control unit can be easily realized with one channel.
  • the evaluation and control unit is designed as a single channel.
  • This embodiment benefits from the possibilities described above and enables a particularly cost-effective implementation of the new safety switching device.
  • the evaluation and control unit includes a microcontroller, which is designed to carry out the functional tests at the defined times, in particular before closing the power supply path to the consumer.
  • microcontroller is used here synonymously for comparable components whose functional scope can be determined at least by the manufacturer. It is therefore not limited to microcontrollers in the narrower sense, but also includes, for example, microprocessors with or without external memory or other programmable components. This embodiment allows a particularly simple and cost-effective implementation of the new safety switching device, wherein the respective range of functions can be set individually. As a result, for example, safety switching devices can be realized inexpensively, which are provided for different types of signaling devices and / or in connection with different types of switching elements.
  • the safety switching device includes a second timer, which is designed to block a connection between the evaluation and control unit and the at least one switching element for a defined period of time, measured from the application of the supply voltage.
  • This embodiment also helps to prevent premature and / or faulty closing of the power supply path to the consumer, even if the at least one switching element is driven by a single-channel evaluation and control unit. In combination with the embodiments already described above, an even higher level of safety is achieved when commissioning the consumer.
  • the new safety switching device includes at least two switching elements, which are arranged in series to redundantly interrupt the power supply path to the load, wherein the evaluation and control unit is adapted to a first dynamic control signal for a first of the at least two switching elements to generate, and a second, in particular static, control signal for a second of the at least two switching elements.
  • This embodiment of the invention uses redundant switching elements in the load circuit in order to enable shutdown of the load even if one of the switching elements fails during the switching operation.
  • the at least two redundant switching elements are still driven in a diversified manner to each other, that is, with two different control signals. Malfunction of the new safety switching device are thereby even less likely. It is particularly preferred if one of the control signals is a dynamic signal, while the other control signal is a static signal. That is to say, both types of control signals can be generated very easily with a microcontroller or a comparable component, wherein due to the different nature of the control signals a simultaneous fault control of the redundant switching elements is extremely unlikely.
  • the at least one switching element is a changeover switch with at least two mutually alternative switching paths, wherein a first switching path is in the power supply path to the consumer, and wherein a second switching path leads to a monitoring unit.
  • This embodiment which in itself represents an inventive development of known safety switching devices, allows a particularly cost-effective implementation of the new safety switching device, in particular with potential-free outputs.
  • the use of a changeover switch makes it possible to use "simple" changeover relays instead of much more expensive and larger relays with positively driven make and break contacts. Therefore, this embodiment allows a particularly cost-effective and small-scale safety switching device, with which nevertheless at least Category 3 of European standard EN 954-1 or a comparable level of security can be achieved.
