Definitions

  • the present invention relates to a safety switching device for automated control of a technical system with a housing, at least one input for receiving an input signal, at least one processing unit for processing the input signal and generating a control signal and at least one output for outputting the control signal to an actuator, wherein the safety switching device further comprising an RJ interface provided on the housing as a user interface for the safety switching device.
  • a safety relay of this type is known, for example, from the operating instructions "PNOZ mOp, PNOZmulti Modular Safety System, Operating Manual - No. 1002053-EN-03, Pilz GmbH & Co. KG".
  • This safety switching device is a safety switching device for failsafe shutdown of an electrical load and in particular for fail-safe shutdown of a machine of a technical system, which poses a danger to people.
  • This safety relay is sold by the assignee of the present invention under the brand name PNOZ ®.
  • This safety switching device has two redundant signal processing channels.
  • Such safety switching devices are mainly used in the industrial sector to on and off electrically driven machines, such as a press or a milling tool. They serve, in particular in conjunction with a mechanically actuated emergency stop button, to switch off the machine quickly and safely in an emergency situation.
  • the power supply of the machine to be disconnected is performed via working contacts of two electromechanical switching elements. As soon as only one of the two switching elements opens its normally open contacts, the power supply of the machine is interrupted.
  • a safety switching device in the sense of the present invention may, for example, also be a module assembly for a programmable controller, for example for a programmable controller, as sold by the assignee of the present invention under the brand PSS® .
  • PSSuniversal® provides a modular programmable control device for standard and safety tasks, as known from the specification "Pilz, PSSuniversal, Programmable Control Systems PSS®, System Description, No. 21256-EN-04".
  • Such modular and configurable safety switching devices often have user interfaces that allow the user to transmit and evaluate status data and / or error messages via Ethernet.
  • user interfaces enable the programming and parameterization of the safety relay via Ethernet and thus via external devices.
  • a direct connection of visualization systems is possible via such user interfaces.
  • so-called Registered Jack (RJ) interfaces the Federal Communications Commission (FCC) standardized interface, are used as the user interface for such safety switching devices.
  • RJ-45 interface is colloquially known as "Ethernet interface”.
  • this object is achieved by a safety switching device of the type mentioned above, wherein on a first side of the RJ interface, a first web and on an opposite second side of the RJ interface, a second web is arranged, wherein the first and the second Ridge project from the housing and for securing a securing element, such as a cable tie or a seal, serve, wherein the first and the second web each having a first portion which projects from the housing, and a second transverse thereto extending portion, which at a disposed away from the housing end of the respective section, wherein the second portion of the first web and the second portion of the second web extending from the respective first portion in opposite directions and away from one another.
  • a securing element such as a cable tie or a seal
  • Such webs which are preferably arranged laterally adjacent to or adjacent to the RJ interface, simplify the attachment of a securing element considerably.
  • security elements for example, cable ties, seals or similar security elements can act.
  • a securing element arranged in this manner on the webs has a number of functions and associated advantages.
  • the possibility of attaching a cable tie or other securing element to the mentioned webs also has a further advantage. If the RJ plug is inserted in the RJ interface, the latter can be additionally secured with the aid of the securing element attached to the webs. This increases the contact reliability between the RJ plug and the RJ interface (RJ socket), as will be explained in detail below. On the other hand, this can prevent undesired release of the RJ plug from the RJ socket during read-out, programming or parameterization of the safety relay.
  • the fuse element can therefore also serve as vibration protection.
  • each ridge preferably extends substantially orthogonal to the second portion of the ridge. This results in a substantially L-shaped profile of the two webs.
  • both the first and the second web each have a substantially L-shaped profile.
  • Such an L-shaped profile has the advantage that an accidental release of the securing element is almost impossible.
  • Each web has each web on its upper side facing away from the housing on a lateral projection, so that can not solve a clamped between the webs cable tie or clamped therebetween seal upwards of the webs.
  • the second, laterally projecting portions of the webs act as a kind of retaining elements or barbs.
  • a cable tie wound around the two webs must therefore be intentionally cut open in order to be able to release it and thus gain access to the RJ interface. In the case of a destroyed seal, this would be completely visible to the other users, so that they receive an alarm signal that the safety relay may have been manipulated.
  • the second sections of the webs point outward from the RJ interface, ie away from one another.
  • the webs mimic the shape of a cable reel so that a securing element can be relatively easily wrapped around the webs or tensioned.
  • a protective cover arranged on the housing is provided to cover the RJ interface, which can be opened and closed.
  • Such a protective cover essentially serves as dust protection for the RJ interface, as long as it is not used.
  • a hinged protective cover for example, a hinged protective cover, but in principle also be provided sliding or removable protective covers.
  • the protective covers can be formed both one or more parts.
  • the protective cover is designed as a protective flap, which is open and can be folded over a hinge axis running transversely to the first and second web.
  • a hinged protective cover has the particular advantage that the protective flap in the open state with an inserted RJ cable another Hedge function exercises.
  • an RJ cable plugged into the RJ interface can additionally be mechanically secured.
  • a cable tie strapped around the bars not only surrounds the bars themselves, but also the RJ cable and the unfolded protective flap.
  • the cable tie additionally presses the protective flap against the RJ cable. This exerts further pressure on the RJ cable, keeping the RJ cable mechanically secure in the RJ interface, so that it does not come off unintentionally.
  • the protective flap is closed and the cable tie or seal is fitted, the protective flap can not be opened due to the blocking securing element, so that access to the RJ interface is prevented in this case.
  • the protective flap is made of an elastic material.
  • the RJ interface is arranged in a recess extending between the first and the second web in the housing, wherein contact points of the RJ interface and the hinge axis of the protective flap are arranged on a same side of the recess.
  • a plugged into the RJ interface (RJ socket) RJ cable, which is mechanically secured in the manner described above using the securing element is automatically tilted by the unfolded and pressed to the cable protective flap. Since the contact points of the RJ interface and the hinge axis of the protective flap are arranged on one and the same side of the recess, the contacts of the RJ connector automatically pressed by the resulting tilting moment to the contact points of the RJ interface. This enormously increases the contact reliability of the RJ male-female connection. Since vibrations can occur at the mentioned safety switching devices during operation, such an increased contact reliability is of enormous advantage, since it improves read-out, programming or parameterization during operation. A break in the contacts of the RJ connection is thus unlikely.
  • first section of the first web and the first section of the second web terminate in or adjoin the recess.
  • the two webs open on opposite sides in the recess. Both webs are preferably orthogonal from the housing surface.
  • a direct adjacency of the two webs to the recess in which the RJ interface is arranged in particular has the advantage of a space-saving arrangement. It is understood, however, that the two webs can in principle also be arranged at a certain distance from the depression.
  • the securing element attached to the webs In order for the securing element attached to the webs to straddle the RJ interface in order to secure the RJ plug in the open state and to prevent access to the RJ interface in the closed state, it is only necessary that the two webs on opposite sides of the RJ interface are arranged. Although an alignment of the two webs is not absolutely necessary, but facilitates the attachment of the fuse element.
