3- OVERLOAD/DECOMPRESSION
PRINCIPE
• La pression dans le vérin de levage varie en fonction de l’angle de levage et de la charge dans la plate-forme.
Le matériel se compose :
• D’un capteur de pression (SP141-2901015090) monté sur le vérin de levage
• D’un capteur analogique d’angle (SR140-2901002700) mesurant l’angle du 1er bras du ciseau par rapport au châssis
• De capteurs TOR de positions basse SQ3 et haute SQ4
• D’un système électronique de traitement (HEAD nœud A)
• En mode de fonctionnement normal, il y a une comparaison permanente des mesures d’angle et de pression avec les mesures enregistrées lors de
la calibration : une alarme de surcharge est déclenchée lorsque la pression mesurée pour un angle donné est supérieure à la pression mémorisée.

Suivant la machine sur laquelle le système est utilisé, il est possible qu’une décompression soit
nécessaire à l’arrêt des mouvements de levage (montée et/ou descente) afin de stabiliser la pression
et ainsi d’avoir une mesure utilisable pour la détection de surcharge.
• Le système de détection de la surcharge ne gère pas cette phase qui est spécifique à la machine.
• Afin de pallier le problème de non exécution de l’à-coup de décompression en fin de mouvement
(arrêt urgence avant la décompression), le système doit permettre un à coup de décompression au
redémarrage de la machine.
• Cette décompression permet « d’éliminer » tous les jeux mécaniques dans les bras de ciseaux et de
mettre la machine dans un état stable d’utilisation.
• Afin de pouvoir éliminer la dispersion , il es nécessaire de calibrer l’électrovanne proportionnelle de
levage YV25 via la console de diagnostique
