Usually, on most industrial electrical installations, the contacts connected in series (closed disconnector, thermal relay, limit switch, etc.) are part of a chain. called "interlocking". When one of these contacts opens, the search for the fault then becomes very tedious for the convenience store, which also causes him a considerable loss of time.
Le dispositif selon l'invention permet de remédier à ces inconvénients: il génère en effet un courant constant à travers tous les contacts à surveiller. Si, sur chaque contact on raccorde une diode électroluminescente, elle s'illuminera dès que son contact respectif s'ouvrira et le dispositif fera apparaître à ses bornes une "tension qui s'interprétera aussitôt comme un défaut.

If a light-emitting diode is connected to each contact, it will light up as soon as its respective contact opens and the device will show a "voltage" across its terminals which will immediately be interpreted as a fault. Thus, the device allows: 1 / to manage the series of contacts as described above by connecting a light-emitting diode on each contact in parallel and also connecting the outgoing feeder and the end of the series of contacts to the device without further modification of the wiring, 2 / d '' indicate whether the control current is correct: it becomes incorrect when the circuit to be checked breaks,

Les voyants pour les contacts sont des diodes électroluminescentes pouvant se monter facilement grâce à leur petite taille Pour des commodités d'installation, il est possible d'utiliser des diodes bicolores (polarisation des voyants),The LEDs for the contacts are light-emitting diodes which can be easily mounted thanks to their small size. For installation convenience, it is possible to use two-color diodes (polarization of the LEDs),
Ce dispositif comprend un boîtier I (figure) renfermant un bloc d'alimentation B-A, un générateur de courant constant disponible entre L1 et L3, des comparateurs qui contrôlent les tensions sur L1 et L2 en assurant le fonctionnement des voyants d8, d9, d10 ainsi que du relais E.This device includes a box I (figure) containing a power supply BA, a constant current generator available between L1 and L3, comparators which control the voltages on L1 and L2 by ensuring the operation of the indicators d8, d9, d10 as well than relay E.
Ce dispositif renferme également un relai E dont les contacts sont disponibles en R,T et C, un temporisateur TP. Sur la face avant apparaissent le voyant de contrôle de ligne d3, les voyants de localisation du défaut éventuel d8 et d9, le voyant d'état du relais E d10 et le bouton de réglage de TP qui se trouve au centre de la façade.This device also contains a relay E whose contacts are available in R, T and C, a timer TP. On the front panel, the line control indicator d3 appears, the indicator lamps for locating a possible fault d8 and d9, the relay status indicator E d10 and the TP adjustment button located in the center of the front panel.
La cablerie unifilaire entre chaque contact permet de pouvoir contrôler et de visualiser simultanément.The single-wire wiring between each contact enables simultaneous control and visualization.
Ce dispositif peut s'adapter comme dit supra sur toute installation préexistente, sans modification de la cablerie initiale.This device can be adapted as said above on any pre-existing installation, without modification of the initial wiring.
Au surplus, le voyant lumineux peut être remplacé par tout système sonore.
Explicatif de la planche 1:In addition, the indicator light can be replaced by any sound system. Explanation of Plate 1:
Les blo cs G et H constituent la ligne à contrôler, c'est à dire l'ensemble des contacts à surveiller , équipés chacun d'un voyant. Le bloc B- A constitue à partir du secteur (220 V enBlocks cs G and H constitute the line to be checked, that is to say all the contacts to be monitored, each equipped with an indicator. Block B- A constitutes from the sector (220 V in
A 1 et A2) une tension continue de 30 V afin d'alimenter le montage.A 1 and A2) a DC voltage of 30 V in order to supply the assembly.
L'ensemble "d1-d2, R1 , R2 et T1" constitue un générateur de courant constant fixé à 20 sA, circulant à travers d3 et les blocs G et H.The set "d1-d2, R1, R2 and T1" constitutes a constant current generator fixed at 20 sA, flowing through d3 and the blocks G and H.
Les résistances R10 et R11 fixent une tension de référence sur les entrées négatives de C1 et C3, Les résistances R4, R5 et la diode d4 fixent une tension de référence variable sur l'entrée négative de C2 suivant l'état des contacts du bloc H.Resistors R10 and R11 fix a reference voltage on the negative inputs of C1 and C3, Resistors R4, R5 and the diode d4 fix a variable reference voltage on the negative input of C2 according to the state of the contacts of block H .
Le voyant d3 illuminé indique que le courant de contrôle est correct, les contacts des blocs G et H étant fermés ou non. Si tous les contacts des blocs G et H sont fermés, leurs voyants respectifs sont éteints c'est alors que les comparateurs C1, C2 et C3 ont leur sortie a l'état 0.The indicator light d3 illuminated indicates that the control current is correct, the contacts of blocks G and H being closed or not. If all the contacts of blocks G and H are closed, their respective LEDs are off then the comparators C1, C2 and C3 have their output at state 0.
Si un ou plusieurs contacts du bloc H s'ouvrent, leurs voyants respectifs s'illuminent alors; les comparateurs C1 et C3 changent d'état et d8 s'illumine, correspondant à un défaut dans le bloc H.If one or more contacts of block H open, their respective LEDs then light up; comparators C1 and C3 change state and d8 lights up, corresponding to a fault in block H.
Si un ou plusieurs contacts du bloc G s'ouvrent, alors leurs voyants respectifs s'illuminent et les comparateurs C1 et C2 changent d'état, d'où d9 s'illumine, correspondant ainsi à un défaut dans le bloc G. Dès qu'un contact des blocs G ou H s'ouvre, le comparateur C1 change d'état.If one or more contacts of block G open, then their respective LEDs light up and the comparators C1 and C2 change state, from which d9 lights up, thus corresponding to a fault in block G. As soon as 'a contact of blocks G or H opens, comparator C1 changes state.
S'il se produisait une rupture de ligne, c'est à dire une coupure entre les bornes L1 et L3, le voyant d3 s'éteindrait alors et le comparateur C1 passerait à l'état 1. Dans cette hypothèse, s'imposerait alors un dépannage traditionnel jusqu'à retour à la normale du courant de ligne. Le bloc TP est un temporisateur réglable de 0 à 5 s, dont le départ est commandé par un niveau 1 sur B 1 ; celui-ci sature le transistor T2
dès qu'il a écoulé son temps, ce qui permet d'illuminer d10 et d'alimenter le relais E si le comparateur C1 est à l'état 1. Le contact inverseur du relais E est disponible sur les bornes C,R et T par une commande extérieu re La résistance R3 permet d'éteindre complètement le voyant d3 s'il se produisait une rupture de ligne. Les résistances R6,R7,R8 et R9 constituent une protection des comparateurs C1,C2,et C3 ainsi que des diodes d5, d6 et d7; d11 élimine les surtensions du relais E. Les résistances R12 et R13 limitent le courant dans les diodes d8 et d9If there was a line break, that is to say a break between the terminals L1 and L3, the indicator light d3 would then go out and the comparator C1 would go to state 1. In this hypothesis, would then be necessary traditional troubleshooting until line current returns to normal. The TP block is a timer adjustable from 0 to 5 s, the start of which is controlled by a level 1 on B 1; this saturates the transistor T2 as soon as its time has elapsed, which makes it possible to illuminate d10 and to supply the relay E if the comparator C1 is in state 1. The reversing contact of the relay E is available on the terminals C, R and T by an external control The resistor R3 makes it possible to completely extinguish the warning light d3 if a line break occurs. The resistors R6, R7, R8 and R9 constitute a protection of the comparators C1, C2, and C3 as well as of the diodes d5, d6 and d7; d11 eliminates overvoltages from relay E. Resistors R12 and R13 limit the current in diodes d8 and d9

Le bloc I représente la face avant du dispositif selon l'invention; au centre de celui-ci l'on aperçoit le bouton de réglage du temporisateur interne; d3, d8, d9 et d10 sont les voyants. A1, B1 , R, T, C, L1 , L2, L3 etBlock I represents the front face of the device according to the invention; in the center of it is the internal timer setting button; d3, d8, d9 and d10 are the LEDs.

L'ensemble I, F1 à F8 représente un exemple de câblage.The set I, F1 to F8 represents an example of wiring.
Les ensembles F1 à F5 et F6 à F8 représentent des chaînes de contacts à surveiller, similaires aux blocsThe sets F1 to F5 and F6 to F8 represent contact chains to be monitored, similar to the blocks
G et H de la planche 1.G and H of plate 1.
Le nombre de contacts à surveiller est limité à 15 car la tension entre L1 et L3 a un maximum de 30 V .The number of contacts to be monitored is limited to 15 because the voltage between L1 and L3 has a maximum of 30 V.
Toutefois, il est possible d'en augmenter le nombre en augmentant la tension interne du dispositif selon l'invention ou si le nombre des contacts ouverts simultanément est égal ou inférieur à 15.However, it is possible to increase the number thereof by increasing the internal voltage of the device according to the invention or if the number of contacts open simultaneously is equal to or less than 15.
La planche 2 représente un exemple avec deux groupes de contacts; toutefois, s'il n'y avait qu'un seul groupe de contact à surveiller, il suffirait de relier les bornes L1 et L2, ou L2 et L3.Plate 2 represents an example with two groups of contacts; however, if there was only one contact group to be monitored, it would suffice to connect terminals L1 and L2, or L2 and L3.
Il est possible de rajouter un deuxième voyant sur un ou plusieurs contacts à surveiller comme représenté sur le bloc F5.
It is possible to add a second indicator on one or more contacts to be monitored as shown on block F5.
