Abstract

Perfeccionamientos en sistemas y dispositivo de control que comprende medios de circuito de entrada para recibir una pluralidad de señales de entrada; medios de conmutación para conmutar periódicamente las señales de entrada; a un estado predeterminado, y medios de control que responden a las entradas conmutadas para diagnosticar la existencia de por lo menos una condición del sistema de posible inseguridad, eligiéndose el estado y el lugar predeterminado de los medios de conmutación para probar o demostrar que, con respecto a una señal de entrada alterna detectar por los medios de control, al menos al dispositivo de circuito de entrada respectivo no ha fallado.
