Description
Klemme 15 positives Potential, wodurch der TransistorTerminal 15 positive potential, whereby the transistor
12 und damit auch der Transistor 13 in ihren leitenden Zustand gesteuert werden. Dies hat zur Folge, daß die Spule 11 mit Strom beaufschlagt, der Schalter 7 betätigt und die Warnlampe 8 zum Aufleuchten gebracht wird, wenn sie in Ordnung ist Nach einer durch den Widerstand 14 und den Kondensator 16 bestimmten Zeitdauer werden der Transistor 12 und damit auch der Transistor12 and thus also the transistor 13 are controlled in their conductive state. As a result, the Current is applied to the coil 11 and the switch 7 is actuated and the warning lamp 8 is made to light up if it is OK after one through the resistor 14 and the capacitor 16 of a certain period of time become the transistor 12 and thus also the transistor
13 in ihren Sperrzustand gesteuert, der Strom durch die Spule 11 wird zu Null und die Warnlampe 8 erlischt wieder.13 is controlled in its blocking state, the current through the Coil 11 becomes zero and the warning lamp 8 goes out again.
Bei der Überwachungseinrichtung nach F i g. 2 liegen in den Glühlampenstromkreisen 3 und 4 zwei Spulen 5' und 6', denen jeweils ein magnetreldabhängiger Schalter 17 bzw. 18 zugeordnet ist, die bei ordnungsgemäßem Zustand der Glühlampenstromkreise 3 und 4 geschlossen sind. Die Schalter 17 und 18 steuern einen Transistor 19, in dessen Emitter-Kollektor-Strecke die Warnlampe 8 liegt Die Basis des Transistors 19 ist des weiteren über die Dioden 20 und 21 mit den Glühlatnpenstromkreisen 3 und 4 verbunden. Parallel zur Emitter-Koiiektor-Strecke des Transistors 19 ist diejenige des Transistors 13 des elektronischen Zeitgliedes 10 geschaltet.In the case of the monitoring device according to FIG. 2 there are two coils 5 'in the light bulb circuits 3 and 4 and 6 ', each of which is assigned a magnetic field-dependent switch 17 or 18, which, when properly State of the light bulb circuits 3 and 4 are closed. The switches 17 and 18 control a transistor 19, in the emitter-collector path of which the warning lamp 8 is located. The base of transistor 19 is also above the diodes 20 and 21 with the incandescent lamp circuits 3 and 4 connected. That of the transistor is parallel to the emitter-coil path of the transistor 19 13 of the electronic timing element 10 is switched.
Erscheint bei Einschalten der Zündung an der Klemme 15 positives Potential, so wird der Transistor 12 und damit auch der Transistor 13 aufgesteuert und die Warnlampe 8 leuchtet auf. Der Transistor 19 ist in seinem Sperrzustand. Nach einer durch den Widerstand 14 und den Kondensator 16 vorgegebenen Zeitdauer wird der Transistor 12 und damit auch der Transistor 13 wieder in seinen Sperrzustand gesteuert und die Lampe 8 erlischt wieder. Bei wirksam geschalteten Glühlampenstromkreisen 3 und 4 sind, wie bereits erwähnt, die Schalter 17 und 18 geschlossen, so daß die Basis des Transistors 19 auf Nullpotential liegt und der TransistorIf positive potential appears at terminal 15 when the ignition is switched on, transistor 12 and thus the transistor 13 is also turned on and the warning lamp 8 lights up. The transistor 19 is in his Lock state. After a period of time predetermined by the resistor 14 and the capacitor 16 the transistor 12 and thus also the transistor 13 are again controlled in its blocking state and the lamp 8 goes out again. When the incandescent lamp circuits 3 and 4 are activated, as already mentioned, the Switches 17 and 18 closed so that the base of transistor 19 is at zero potential and the transistor
19 sich in seinem Sperrzustand befindet Sobald jedoch eine der beiden Glühlampen 1 oder 2 ausfällt, wird diese Verbindung aufgetrennt und positives Potential von der Klemme 30 gelangt über die beiden Dioden 20 bzw. 21 auf die Basis des Transistors 19, der dadurch aufgesteuert wird. Die Warnlampe 8 leuchtet auf und zeigt an, daß eine der Glühlampen 1 bzw. 2 ausgefallen ist.19 is in its locked state As soon as one of the two light bulbs 1 or 2 fails, it will The connection is broken and a positive potential from terminal 30 is passed through the two diodes 20 and 21, respectively on the base of transistor 19, which is thereby turned on. The warning lamp 8 lights up and indicates that one of the light bulbs 1 or 2 has failed.
Bei der in F i g. 3 dargestellten Überwachungseinrichtung steuern die Schalter 17 und 18 einen Transistor 22, in dessen Emitter-Kollektor-Strecke die Warnlampe 8 liegt. In Reihe mit den beiden Schaltern 17 und 18 liegt des weiteren die Emitter-Kollektor-Strecke des Transistors 12' des elektronischen Zeitgliedes 10'. Die Basis des Transistors 22 steht des weiteren über zwei DiodenIn the case of the in FIG. 3, the monitoring device shown, the switches 17 and 18 control a transistor 22, in the emitter-collector path of which the warning lamp 8 is located. In series with the two switches 17 and 18 is located furthermore the emitter-collector path of the transistor 12 'of the electronic timing element 10'. The base of the transistor 22 is also via two diodes
20 und 21 mit den beiden Glühlampenstromkreisen 3 und 4 in Verbindung. Nach Einschalten der Zündung werden die Klemmen 15 mit positivem Potential beaufschlagt. Da jedoch sowohl der Transistor 22 als auch der Transistor 12' in ihrem Sperrzustand und die beiden Schalter 17 und 18 geöffnet sind, leuchtet die WarnlaTipe 8 nicht auf. Sobald jedoch die Glühlampenstromkreise 3 und 4 eingeschaltet werden, wird die Basis des Transistors 22 über die Dioden 20 und 2Ί mit positivem Potential beaufschlagt, der Transistor 22 in seinen leitenden Zustand gesteuert und die Warnlampe 8 leuchtet eo auf. Die Schalter 17 und 18 sind, wenn sich die Glühlampen 1 und 2 in einem ordnungsgemäßen Zustand befinden, geschlossen, während der Transistor 12' sich noch in seinem Sperrzustand befindet. Nach einer durch den Widerstand 14' und den Kondensator 16' bestimmten Zeitdauer nach Einschalten der Glühlampenstromkreise wird der Transistor 12' ia seinen leitenden Zustand gesteuert und dadurch die Basis des Transistors 22 über die beiden Schalter 17 und 18 und die Emitter-Kollektor-Strecke des Transistors 12' auf Nullpotential gelegt Die Warnlampe 8 erlischt wieder. Sobald eine der Glühlampen 1 oder 2 nicht mehr intakt sind, öffnet der dieser Glühlampe zugeordnete Schalter 17 bzw. 18. Dadurch wird die Basis des Transistors 22 wieder über die Dioden 20 und 21 auf positives Potential hochgezogen und die Warnlampe 8 leuchtet auf.20 and 21 with the two bulb circuits 3 and 4 in connection. After switching on the ignition, the terminals 15 have a positive potential applied to them. However, since both the transistor 22 and the transistor 12 'are in their blocking state and the two switches 17 and 18 are open, the warning tube 8 does not light up. However, as soon as the incandescent lamp circuits 3 and 4 are switched on, the base of the transistor 22 is applied with a positive potential via the diodes 20 and 2Ί, the transistor 22 is controlled in its conductive state and the warning lamp 8 lights up. The switches 17 and 18 are closed when the incandescent lamps 1 and 2 are in a proper state, while the transistor 12 'is still in its blocking state. After a period of time determined by the resistor 14 'and the capacitor 16' after the incandescent lamp circuits have been switched on, the transistor 12 'generally controls its conductive state and thereby the base of the transistor 22 via the two switches 17 and 18 and the emitter-collector path of the The transistor 12 'is set to zero potential. The warning lamp 8 goes out again. As soon as one of the incandescent lamps 1 or 2 is no longer intact, the switch 17 or 18 assigned to this incandescent lamp opens. As a result, the base of the transistor 22 is pulled up to positive potential again via the diodes 20 and 21 and the warning lamp 8 lights up.
