Description

Die Erfindung betrifft eine Mine, insbesondere eine Panzerabwehr-Verlege­mine mit einer Einrichtung zum Wiedersichern der Mine und einem von der Sicherstellung in die Scharfstellung bewegbaren Rotor, der in der Sicher­stellung mechanisch festlegbar ist, sowie mit einer Markierungsladung.The invention relates to a mine, in particular an anti-tank installation mine with a device for re-securing the mine and a rotor which can be moved from the safeguard to the arming mechanism and which can be mechanically fixed in the safeguard, and with a marker charge.

Eine Mine dieser eingangs genannten Art ist aus der DE-AS 24 23 912 be­kannt. Bei dieser bekannten Mine ist eine Einrichtung zum Wiedersichern mit einem aus der Sicher- in die Scharfstellung und aus der Scharf- in die Wiedersicherstellung unter dem Einfluß eines Gesperres bewegbaren Schaltglied vorgesehen, dem eine die Wiedersicherstellung anzeigende Vorrichtung zugeordnet ist. In der eingenommenen Wiedersicherstellung wird die Markierungsladung gezündet, wobei gleichzeitig das Sprengla­dungsanzündhütchen mit vernichtet wird. Von Nachteil bei einer solchen Mine ist es, daß nicht nur die Markierungsladung nach erfolgtem Wieder­sichern und ggf. eine neue Batterie eingesetzt werden muß, sondern daß zusätzlich die gesamte Wiedersicherungs-Einrichtung ausgebaut, zerlegt und wieder neu eingesetzt werden muß, wenn eine Wiederverwendung dieser Mine vorgesehen ist.A mine of the type mentioned is known from DE-AS 24 23 912. In this known mine, a device for re-securing is provided with a switching element which can be moved from the safe to the arming and from the arming to the re-securing position under the influence of a locking mechanism, to which a device indicating the re-securing is assigned. The marker charge is ignited in the re-seizure that has been taken, and the explosive charge cap is also destroyed at the same time. A disadvantage of such a mine is that not only the marker charge after re-securing and possibly a new battery must be used, but also that the entire re-securing device must be removed, disassembled and re-used if this mine is to be reused is provided.

Ausgehend von dem vorgenannten Stand der Technik ist es bei einer Mine der eingangs genannten Art Aufgabe der Erfindung, eine Wiedersicherungs-­Vorrichtung vorzusehen, die rückstellbar und damit wieder sicherbar ist und auf diese Weise für die Mine beliebig oft verwendbar bleibt.On the basis of the aforementioned prior art, it is the object of the invention for a mine of the type mentioned at the outset to provide a re-securing device which can be reset and thus be secured again and in this way remains usable for the mine as often as desired.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Einrichtung zum Wiedersichern der Mine eine mechanische Steuerungseinrichtung ist, die einerseits bei Empfang eines ersten Signals aus einer zugeschalteten Elektronik den Rotor in die Scharfstellung dreht und andererseits bei Empfang eines zweiten Signals aus der Elektronik die Sicherungsein­richtung der Mine in den energielosen Wiedersicherungszustand zu­rückführt; anschließend löst die Elektronik die Markierungsladung zur Anzeige des Wiedersicherungszustandes der Mine aus. Dies bedeutet, daß die in Scharfstellung befindliche Mine durch ein elektrisches Signal aus einer der Mine zugeordneten Elektronik gezündet werden kann. Soll eine Zündung nicht erfolgen, was sowohl nach dem einge­stellten Zeitablauf als auch vor Ablauf der eingestellten Zeit möglich ist, so gibt ein zweites Signal aus der besagten Elektronik an die Sicherungseinrichtung der Mine den Befehl, wieder in den energielosen Anfangszustand zurückzufahren. Die vorliegende Erfindung offenbart damit eine Sicherungseinrichtung für eine Panzerabwehr-Verlegemine, die rückstellbar und damit wieder sicherbar ist und auf diese Weise die Mine beliebig oft verwendbar macht.According to the invention, this object is achieved in that the device for re-securing the mine is a mechanical control device which, on the one hand, rotates the rotor into the armed position on receipt of a first signal from a connected electronic system and, on the other hand, at Receiving a second signal from the electronics returns the mine safety device to the de-energized state of restoration; the electronics then trigger the marker charge to indicate the mine’s recovery status. This means that the mine in focus can be ignited by an electrical signal from electronics associated with the mine. If an ignition is not to take place, which is possible both after the set time has elapsed and before the set time has elapsed, a second signal from said electronics gives the mine safety device the command to return to the deenergized initial state. The present invention thus discloses a security device for an anti-tank installation mine, which can be reset and thus secured again and in this way makes the mine usable as often as desired.

In Ausbildung der Erfindung kann die Steuerungseinrichtung aus einer arretierbaren Steuerwelle gebildet sein, auf der zwei koaxial ange­ordnete Steuerräder angeordnet sind, die durch eine Drehfeder mitein­ander verbunden sind und von denen das eine Steuerrad mit der Siche­rungseinrichtung der Mine antriebsverbunden und auf der Steuerwelle drefest gelagert ist, während das andere Steuerrad über ein Zwischen­rad mit dem Rotor antriebsverbunden ist, der durch ein Kraftelement festlegbar ist, das für den Empfang zur Auslösung der Wirkladung mit der Elektronik der Mine in Wirkverbindung steht.In an embodiment of the invention, the control device can be formed from a lockable control shaft, on which two coaxially arranged control wheels are arranged, which are connected to one another by a torsion spring and of which one control wheel is drive-connected to the safety device of the mine and rotatably mounted on the control shaft, while the other steering wheel is drive-connected to the rotor via an intermediate wheel, which can be fixed by a force element which is operatively connected to the electronics of the mine for the reception to trigger the active charge.

Dabei kann ferner auf der Steuerwelle eine Einfallscheibe drehfest angeordnet sein, die nach 180° ihres Umfanges eine Ausnehmung auf­weist, in die ein gefederter Kern eines radial zur Steuerwelle ange­ordneten Hubmagneten einrastet, und daß das Steuerrad, welches mit der Sicherungseinrichtung der Mine antriebsverbunden ist, eine zu­mindest 180°-große Ringausnehmung besitzt, in welcher ein Stift drehbegrenzend axial einsteht.It can also be rotatably arranged on the control shaft, an incidence disk, which has a recess after 180 ° in its circumference, in which a spring-loaded core of a radially arranged to the control shaft solenoid engages, and that the steering wheel, which is drive-connected to the safety device of the mine, one has at least 180 ° ring recess, in which a pin protrudes axially to limit rotation.

Ferner kann die Sicherungseinrichtung aus dem mit der Steuerwelle verbundenen Steuerrad mit eingesetzter Drehfeder und dem mit dem Steuerrad antriebsverbundenen Federhaus mit eingesetzter Drehfeder und koaxial angeordnetem Federkern sowie dem über ein Kupplungs­rad mit dem Federhaus getriebeverbundenen Gangwerk gebildet sein. Der Federkern kann durch eine Spiralwelle unter Vermittlung eines Aufzugrades aufspannbar sein und durch eine Sperre in gespanntem Zustand feststellbar sein, wobei die Sperre einerseits durch einen Drehhebel auf der Minenoberfläche auslösbar ist und andererseits durch die Arretierbewegung des Kerns des Hubmagneten entriegelbar ist, wobei der Drehhebel gleichzeitig mit der Spiralwelle in Druck­verbindung steht und ferner einen Schalter zum Anlaufen der Unruh des Gangwerkes betätigt.Furthermore, the securing device can be formed from the control wheel connected to the control shaft with an inserted torsion spring and the barrel connected to the steering wheel with an inserted torsion spring and coaxially arranged spring core and the gear mechanism connected to the barrel via a clutch wheel. The spring core can be clamped by a spiral shaft with the help of an elevator wheel and can be locked in a tensioned state by a lock, the lock being able to be released on the one hand by a rotary lever on the surface of the mine and on the other hand being unlockable by the locking movement of the core of the lifting magnet, the rotary lever being simultaneous is in pressure connection with the spiral shaft and furthermore actuates a switch for starting the balance of the gear mechanism.

In besonderer erfinderischer Ausbildung kann der Drehhebel bei Drehung in die Scharfstellung den Batteriefachdeckel verriegeln und bei gleichzeitig ausgeübtem Axialdruck die Spiralwelle in Drehung ver­setzen, welche die aufgenommene Kraft in eine etwa am unteren Stirn­ende der Spiralwelle angeordnete Klemmscheibe leitet, die am Außenum­fang tangential verlaufende Einschnitte aufweist, in denen Klemm­rollen lagern, die an der Innenwand eines mit dem Federkern antriebs­verbundenen Aufzugsrades anliegen, wobei der durch Drehung des Dreh­hebels in die Scharfstellung der Mine durch eine mechanische Sperre in energiegeladenem Zustand gesperrte Federkern die Drehfeder des Federhauses spannt, welches einerseits über das Kupplungsrad das Gangwerk antreibt und andererseits gleichzeitig mit dem einen Steuer­rad der Steuerwelle getriebeverbunden ist, das über eine Drehfeder mit einem zweiten Steuerrad der Steuerwelle in Verbindung steht, welches seinerseits über ein Zwischenrad mit dem Rotor in Eingriff steht, der durch ein Kraftelement in der Sicherstellung gehalten ist, und daß die Steuerwelle in Lauerstellung durch den radialen Eingriff eines Kerns eines Hubmagneten in eine Einfallscheibe fest­gelegt ist, wobei die Arretierbewegung des Kerns des Hubmagneten gleichzeitig auf einen Hebel zur Entriegelung der Federkernsperre wirkt, und daß das Kraftelement durch ein Signal der Elektronik aus der Riegelstellung des Rotors gelöst wird, während ein zweites Signal geeignet ist, den Kern des Hubmagneten außer Eingriff mit der Ein­fallscheibe zu bringen.In a particularly inventive embodiment, the rotary lever can lock the battery compartment cover when it is turned into focus and, when the axial pressure is exerted at the same time, set the spiral shaft in rotation, which directs the force absorbed into a clamping disk arranged approximately at the lower end of the spiral shaft, which has tangential incisions on the outer circumference, in which pinch rollers are supported, which rest against the inner wall of an elevator wheel that is connected to the spring core, whereby the spring core, locked by turning the rotary lever into focus position by a mechanical lock in the energized state, tensions the torsion spring of the barrel, which on the one hand tensions the gear via the clutch wheel drives and, on the other hand, is gear-connected at the same time to the one control wheel of the control shaft, which is connected via a torsion spring to a second control wheel of the control shaft, which in turn engages with the rotor via an intermediate wheel stands, which is held in the securing by a force element, and in that the control shaft is fixed in wait position by the radial engagement of a core of a lifting magnet in an incidence disk, the locking movement of the core of the lifting magnet acting simultaneously on a lever for unlocking the spring-core lock, and that the force element is released from the locking position of the rotor by a signal from the electronics, while a second signal is suitable for disengaging the core of the lifting magnet from the incident disk.

Der besondere Vorteil dieser Mine liegt in der Wiederverwendbarkeit, welche mit nur geringem technischen Aufwand erzielt wird. Dies be­deutet, daß nach Wiedersichern der Mine nur die Markierungsladung und die Batterie ausgetauscht werden müssen. Die gesamte Wieder­sicherungseinrichtung bleibt in dem eingebauten, energielosen An­fangszustand erhalten.The particular advantage of this mine is that it can be reused, which is achieved with little technical effort. This means that after the mine is restored, only the marker charge and battery need to be replaced. The entire reinsurance facility remains in the installed, energy-free initial state.

Ein weiterer Vorteil bei dieser Verlegemine ist die Verlegesicher­heit bei Scharfstellung, welche durch das angebaute Gangwerk ermög­licht wird.Another advantage of this laying lead is the laying reliability when focusing, which is made possible by the attached gear mechanism.

Die dargestellte Mine 44 dem Gehäuse 29 bildet einen im wesent­lichen kreisförmigen Körper mit einer Oberfläche 30, in welche der Batteriefachdeckel 27 eingelassen ist.The refill 44 shown in the housing 29 forms an essentially circular body with a surface 30 into which the battery compartment cover 27 is embedded.

Ein Drehhebel 1 ist in der Sicherstellung der Mine 44 durch eine Lasche 28 auf der Minenoberfläche arretierbar und steht in der Scharf­stellung gegen einen Anschlag 31 an der Deckelunterseite oder am Gehäusedeckel an. Eine Nase 46 am Drehhebel 1 liegt in der Scharf­stellung des Drehhebels 1 unmittelbar über dem Batteriefachdeckel 27, der in dieser Position nicht geöffnet werden kann. Die Drehachse des Drehhebels 1 ist in Fig. 1 bei 47 erkennbar.A rotary lever 1 can be locked in the securing of the lead 44 by a tab 28 on the lead surface and is in focus against a stop 31 on the underside of the cover or on the housing cover. When the rotary lever 1 is in focus, a nose 46 on the rotary lever 1 lies directly above the battery compartment cover 27, which cannot be opened in this position. The axis of rotation of the rotary lever 1 can be seen at 47 in FIG. 1.

Der Start der Entsicherungszeit und damit auch der Start der mög­lichen Funktionsabläufe beginnt mit dem Entfernen der Lasche 28 von dem Drehhebel 1.The start of the unlocking time and thus also the start of the possible functional sequences begins with the removal of the tab 28 from the rotary lever 1.

Durch Druck auf den Drehhebel bis zu einem mechanisch Anschlag wird die Aufzugseinrichtung nach den Figuren 3 und 4 in der Weise betätigt, daß über die Spiralwelle 2 und die untere Friktionsschei­be 3 die Kraft in die Klemmscheibe 4 und von dort weiter in die Klemmrollen 5 geleitet wird. Die Klemmrollen 5 liegen dabei an der Innenwand 43 des Aufzugsrades 6 an und nehmen dieses Aufzugsrad bei der Drehbewegung mit, solange die Kraft über den Axialdruck von der Spiralwelle 2 zugeführt wird. Das Aufzugsrad 6 steht mit dem Federkern 7 in Antriebsverbindung, der seinerseits mit dem Feder­haus 10 und der in dem Federhaus 10 angeordneten Drehfeder 9 in Verbindung steht.By pressing the rotary lever up to a mechanical stop, the elevator device according to FIGS. 3 and 4 is actuated in such a way that the force is conducted into the clamping disc 4 via the spiral shaft 2 and the lower friction disc 3 and from there into the clamping rollers 5 . The pinch rollers 5 lie against the inner wall 43 of the elevator wheel 6 and take this elevator wheel with them during the rotational movement as long as the force is supplied by the spiral shaft 2 via the axial pressure. The elevator wheel 6 is in drive connection with the spring core 7, which in turn is connected to the barrel 10 and the torsion spring 9 arranged in the barrel 10.

Würde die Axialkraft und damit die Drehbewegung der Spiralwelle 2 aufgehoben so entsteht Schlupf zwischen den Klemmrollen 5 und dem Aufzugsrad 6. Der Federkern 7 könnte wieder entspannen, so daß seine Kraft in die Sperrichtung des Aufzugsrades 6 wirkt. Durch den ent­standenen Schlupf zwischen den Klemmrollen 5 und dem Aufzugsrad 6 würde diese Kraft nicht weiter auf die Spiralwelle 2 übertragen. Das Aufzugsrad 6 läuft in diesem Fall ohne Kraftübertragung mit, bis der Federkern 7 keine Energie mehr abgibt.If the axial force and thus the rotational movement of the spiral shaft 2 were canceled, then slip would occur between the pinch rollers 5 and the elevator wheel 6. The spring core 7 could relax again, so that its force acts in the blocking direction of the elevator wheel 6. Due to the resulting slippage between the pinch rollers 5 and the elevator wheel 6, this force would not be transmitted further to the spiral shaft 2. In this case, the elevator wheel 6 runs with no power transmission until the spring core 7 no longer releases energy.

Mit dem Betätigen der Aufzugseinrichtung 32 ist nun die Drehfeder 9 des bis dahin energielosen Gangwerkes 8 aufgezogen worden.With the actuation of the elevator device 32, the torsion spring 9 of the gear mechanism 8, which had previously been without energy, has now been wound up.

Die aufgebrachte Energie bleibt im Federhaus 10 gespeichert, bis der Drehhebel 1 in die Scharfstellung gedreht wird. Gleichzeitig mit der Umstellung des Drehhebels 1 in die Scharfstellung wird eine mechanische Sperre 11 ausgelöst, die den Federkern 7 in dem energie­geladenen Zustand sperrt. Zugleich mit dem Umstellung des Drehhebels 1 wird ein Kippschalter 12 betätigt, der die Unruh 13 des Gangwerkes 8 zum Anlaufen bringt. Die Unruh 13 schwingt also aus der Nullstellung heraus an. Das mechanische Gangwerk 8 wird durch die Drehfeder 9 des Federhauses 10 angetrieben und läuft innerhalb einer vorgegenbenen Zeit ab, die einer Sicherheit für Personen und Einrichtungen bei dem Verlegen der Mine 44 und der Betätigung in Scharfstellung ent­spricht.The energy applied remains stored in the barrel 10 until the rotary lever 1 is turned to the arming position. Simultaneously with the changeover of the rotary lever 1 to the arming position, a mechanical lock 11 is triggered, which locks the spring core 7 in the energized state. Simultaneously with the changeover of the rotary lever 1, a toggle switch 12 is actuated, which causes the balance 13 of the gear mechanism 8 to start up. The balance 13 swings out of the zero position. The mechanical gear mechanism 8 is driven by the torsion spring 9 of the barrel 10 and expires within a predetermined time, which corresponds to a safety for people and facilities when the mine 44 is moved and the activation in focus.

Die Drehfeder 9 zieht gleichzeit über das Steuerrad 17 die bis dahin energielose Drehfeder 15 der Steuerwelle 16 auf .The torsion spring 9 simultaneously pulls on the control wheel 17 the previously energetic torsion spring 15 of the control shaft 16.

Die Drehbewegung der Steuerwelle 16 wird begrenzt durch einen axialen Stift 41, der in einer 180° großen Ringausnehmung 21 des Steuer­rades 17 eingreift. Entsprechend der vorgegebenen Mechanik hat die Steuerwelle 16 die Drehung von 180° in etwa 10 Minuten durchgeführt. In ihrer Stellung kann nun der gefederte Kern 33 des Hubmagneten 18 in eine Aussparung 34 der auf der Steuerwelle 16 angebrachten Ein­fallscheibe 19 einfallen und die Steuerwelle 16 damit arretieren. Gleichzeitig mit dieser Arretierbewegung des Kerns 33 des Hubmag­neten 18 wird über eine starre Hebelverbindung 35 die Federkern­sperre 11 entriegelt. Dadurch kann die im Federhaus 10 verbliebene Restenergie über den Federkern 11 in Richtung auf das Aufzugsrad 6 abgeführt werden, bis die Drehfeder 9 des Federhauses 10 energielos ist. Die Federkernsperre 11 bleibt entriegelt. Sie wird durch die Sperrfeder 20 (Blattfeder) in der hintersten Stellung gehalten und erst durch die Steuerkurve 36 der Schaltbuchse 37 wieder gelöst.The rotational movement of the control shaft 16 is limited by an axial pin 41 which engages in a 180 ° annular recess 21 in the control wheel 17. In accordance with the specified mechanics, the control shaft 16 has carried out the rotation of 180 ° in about 10 minutes. In its position, the sprung core 33 of the solenoid 18 can now fall into a recess 34 in the cover plate 19 mounted on the control shaft 16 and thus lock the control shaft 16. Simultaneously with this locking movement of the core 33 of the lifting magnet 18, the spring core lock 11 is unlocked via a rigid lever connection 35. As a result, the residual energy remaining in the barrel 10 can be dissipated via the spring core 11 in the direction of the elevator wheel 6 until the torsion spring 9 of the barrel 10 is without energy. The spring lock 11 remains unlocked. It is held in the rearmost position by the locking spring 20 (leaf spring) and only released again by the control cam 36 of the switching socket 37.

Die über die Spiralwelle 2 und den Federkern 7 augebrachte Energie ist nun in der Drehfeder 15 der Steuerwelle 16 gespeichert. Sie bleibt hier solange gespeichert, bis von der Elektronik 38 oberhalb der Wiedersicherungseinrichtung ein Signal entweder zur Auslösung der Wirkladung oder zur Rückstellung des gefederten Kerns 33 des Hugmagneten 18 kommt.The energy applied via the spiral shaft 2 and the spring core 7 is now stored in the torsion spring 15 of the control shaft 16. It remains stored here until a signal from the electronics 38 above the reinsurance device either for triggering the active charge or resetting of the sprung core 33 of the hug magnet 18.

Die Mine 44 befindet sich nun in Lauerstellung. Während dieser Zeit ist es nicht möglich, die Mine 44 durch Zurückdrehen des Drehhebels 1 oder durch den Ausbau der Batterie durch Abnahme des Batteriefach­deckels 27 unbrauchbar zu machen. Während der Wirkzeit der Mine 44 wird ständig die anliegende Spannung überprüft. Wird ein plötzlicher Spannungsabfall, etwa durch Umlegen des Drehhebels 1 in die Sicher­stellung registriert, so wird automatisch das Auslösesignal für die Wirkladung gegeben und die Mine 44 zündet.Mine 44 is now in wait. During this time it is not possible to make the mine 44 unusable by turning back the rotary lever 1 or by removing the battery by removing the battery compartment cover 27. The applied voltage is constantly checked during the action time of the mine 44. If a sudden drop in voltage is registered, for example by turning the rotary lever 1 into the safety device, the trigger signal for the active charge is automatically given and the mine 44 ignites.

Das Signal zur Auslösung der Wirkladung bewirkt die Zündung des Kraftelementes 23, wodurch der Rotor 14 aus seiner festgelegten Position freigegeben wird. Die Energie der Drehfeder 15 bewirkt nun über das Steuerrad 24, welches koaxial zum Steuerrad 17 auf der Steuerwelle 16 angeordnet ist, eine Drehung des antriebsver­bundenen Zwischenrades 25 und damit schließlich die Drehung des wiederum antriebsverbundenen Rotors 14 in die Scharfstellung zur Zündung der Mine 44.The signal for triggering the active charge causes the force element 23 to be ignited, as a result of which the rotor 14 is released from its fixed position. The energy of the torsion spring 15 now causes, via the steering wheel 24, which is arranged coaxially to the steering wheel 17 on the control shaft 16, a rotation of the drive-connected intermediate wheel 25 and thus finally the rotation of the in turn drive-connected rotor 14 into the armed position to ignite the mine 44.

Das Signal zur Rückstellung des geferderten Kerns 33 des Hubmagneten 18 aus der Elektronik 38 bewirkt dagegen, daß sich die Drehfeder 15 über das Steuerrad 17, das Federhaus 10 mit dem Federkern 7 und das Kupplungsrad 26 entspannt. Nach erfolgtem Ablauf ist die Siche­rungseinrichtung wieder in der energielosen Ausgangsstellung und gesichert. Nach diesem Wiedersichern erfolgt die Zündung der Markie­rungsladung, um den wieder gesicherten Zustand der Mine 44 anzuzeigen.By contrast, the signal for resetting the core 33 of the lifting magnet 18 from the electronics 38 causes the torsion spring 15 to relax via the control wheel 17, the barrel 10 with the spring core 7 and the clutch wheel 26. After the expiry, the safety device is again in the de-energized starting position and secured. After this re-securing, the marker charge is ignited to indicate the restored state of the mine 44.

Durch das Einsetzen einer neuen Batterie sowie einer neuen Markie­rungsladung 22 kann die Mine 44 sofort wiedder ensatzbereit gemacht und neu verlegt werden. Dieser Vorgang ist beliebig oft wiederhol­bar.By inserting a new battery and a new marker charge 22, the refill 44 can immediately be made ready for use again and relocated. This process can be repeated any number of times.

Das Signal aus der Elektronik 38 zur Wiedersicherung der Mine 44 erfolgt entweder nach Ablauf der in der Elektronik vorgegebenen Zeit oder aber durch ein von außen aus gesendetes Signal einer Fernbe­dienung oder dergleichen.The signal from the electronics 38 for the recovery of the mine 44 takes place either after the time specified in the electronics has elapsed or by a signal from a remote control or the like sent from the outside.

Die elektrischen Verbindungen von der Elektronik 38 zu den einzel­nen Elementen der Mine zeigt Fig. 2.The electrical connections from the electronics 38 to the individual elements of the mine are shown in FIG. 2.

So führt eine Leitung 48 von der Elektronik 38 zu einer hier nicht näher dargestellten Batterie, wodurch die Energieversorgung sicher­gestellt ist. Die Leitung 49 verbindet die Elektronik 38 mit dem Kraftelemente 23 und die weitere Leitung 50 ist eine Verbindung zwischen der Elektronik 38 und der Wirkladung.Thus, a line 48 leads from the electronics 38 to a battery, not shown here, which ensures the energy supply. The line 49 connects the electronics 38 to the force elements 23 and the further line 50 is a connection between the electronics 38 and the active charge.

Ferner ist die Elektronik 38 angeschlossen an den Hubmagneten 18 durch die Leitung 51, an einen Schalter 56 durch die Leitung 52, an die Markierungsladung durch die Leitung 53, an die Abräumladung (nicht gezeigt) durch die Leitung 54 und schließlich an einen Span­nungswächter (nicht gezeigt) durch die Leitung 55.Furthermore, the electronics 38 is connected to the solenoid 18 through line 51, to a switch 56 through line 52, to the marker charge through line 53, to the clearing charge (not shown) through line 54, and finally to a voltage monitor (not through line 55.

Auf der Sicherheitseinrichtung befindet sich ein hier ebenfalls nicht dargestellter, an sich bekannter gemeinsamer Massepunkt.A common ground point, which is known per se and is also not shown, is located on the safety device.
