Abstract
EN COMBINACION CON UN CIRCUITO ELECTRONICO (10) QUE CONTROLA EL OPERADOR DE UN MEDIDOR QUE CENTRA EL SUMINISTRO DE MERCANCIAS (20), SE PROPORCIONA UN APARATO PARA PROTEGER EL CIRCUITO DE DESCARGAS DE ALTA TENSION INTERFERENTES, QUE CONSTA DE UNA MEMORIA (14) EN LA QUE SE ALMACENA UN MODELO DE SEÑALES UTILIZANDO UN CIRCUITO GUARDIAN (24) CUANDO TIENE LUGAR UN APAGON ORDENADO DEL CONTROLADOR, DEBIDO POR EJEMPLO AL VENCIMIENTO DE UN CREDITO, Y CUANDO SE VUELVE A ENCENDER EL CONTROLADOR, EL CIRCUITO GUARDIAN LEE LA MEMORIA Y GENERA UNA SEÑAL DE CONTROL DE APAGON DEL MODELO DE SEÑAL ALMACENADO QUE NO ESTA CONFIGURADA EN LA MEMORIA.
