Abstract

APARATO DE MANDO DE SEGURIDAD. CON AYUDA DE UN APARATO DE MANDO DE SEGURIDAD (1) SE SUPERVISAN DOS SENSORES (2, 2'') QUE COMPRUEBAN LA MISMA FUNCION EN UNA INSTALACION. LOS DOS SENSORES (2, 2'') ESTAN CONECTADAS A LAS ENTRADAS CORRESPONDIENTES (4, 4'') DEL APARATO DE MANDO DE SEGURIDAD (1). EL APARATO DE MANDO DE SEGURIDAD (1) CONTIENE DOS CIRCUITOS DE SUPERVISION DE TIEMPO (9, 9'') DE LOS CUALES CADA UNO TIENE ASIGNADA UNA ENTRADA (4, 4''). LOS CIRCUITOS DE SUPERVISION DE TIEMPO, (9, 9'') SOLO SUMINISTRAN UNA SEÑAL DE SALIDA, CUANDO LAS SEÑALES EN LAS ENTRADAS (4,4'') DEL APARATO DE MANDO DE SEGURIDAD (1) AUMENTAN SIMULTANEAMENTE AL VALOR DE TRABAJO DENTRO DEL RETICULO DE TIEMPO REALIZADO. SI ES ESTE EL CASO, SE ACTIVA UN CIRCUITO (11) DE REALIMENTACION, QUE SUPRIME PRIMERO LA ACCION DEL RETICULO DE TIEMPO HASTA QUE EN UNA DE LAS ENTRADAS (4, 4'') LA SEÑAL RETROCEDE DEL VALOR EN EL ESTADO DE TRABAJO AL ESTADO DE REPOSO.
