Abstract

Il circuito è in grado di rilevare la presenza di un corto-circuito fra l'alimentazione (VCC) e l'uscita (T) di un dispositivo (1) di pilotaggio del tipo comprendente un interruttore (2) definente il morsetto di uscita (T) del dispositivo a cui viene collegato un carico induttivo (L) il cui altro morsetto è collegato alla linea di alimentazione (VCC), una coppia di rami (18, 20; 26) di ricircolo della corrente collegabili in parallelo al carico (L), nonché un'unità di comando che controlla l'apertura e la chiusura dell'interruttore (2) in modo che il carico (L) sia attraversato da una corrente di valore crescente fino ad un primo livello prefissato durante una prima fase di crescita e poi decrescente fino ad un secondo livello prefissato durante una prima fase di ricircolo, quindi oscillante intorno ad un livello di mantenimento durante successive fasi di crescita e di ricircolo. Il circuito di rilevamento del corto-circuito comprende una coppia di sensori di corrente (60, 61) in grado di rilevare ciascuno la corrente fluente in un rispettivo ramo di ricircolo (18, 20; 26) durante la prima fase di ricircolo e, rispettivamente, durante le successive fasi di ricircolo. I sensori di corrente (60, 61) sono collegati ad un circuito di segnalazione guasto (73-85) in grado di generare un segnale di guasto quando viene rilevata l'assenza di corrente nei rami di ricircolo nelle fasi di ricircolo.Figure 4 e 5
