Abstract

EL CONTROLADOR DEL COMPRESOR (100) CONSTA DE UN CIRCUITO TEMPORIZADOR (106) PARA LLEVAR UNA FALLA DETECTADA EN UN COMPRESOR AL FINAL DEL INTERVALO DE RETARDO (111). CUANDO LA FALLA TIENE LUGAR DURANTE UN TIEMPO MAYOR QUE UN LIMITE DE TIEMPO PREDETERMINADO, EL CONTROLADOR (100) CORTA EL SUMINISTRO ELECTRONICO COMPRESOR (111). SI SE CORRIGE LA FALLA DENTRO DEL LIMITE DE TIEMPO PREDETERMINADO, INCLUSO SI SOLO ES MOMENTANEAMENTE, EL PROCESO DE TEMPORIZACION SE CONVIERTE EN DISCONTINUO Y EL CONTROLADOR CONTINUA PARA CONTROLAR EL ESTADO DEL COMPRESOR. EL CONTROLADOR CONSTA TAMBIEN DE UN TEMPORIZADOR DE RETARDO (108) PARA RETARDAR LA REACTIVACION CON CORRIENTE EXCITADORA DEL COMPRESOR (111) DESPUES DE QUE TENGA LUGAR UNA INTERRUPCION O PERDIDA DE POTENCIA. EL RETARDO EVITA EL FUNCIONAMIENTO CICLICO CORTO DEL COMPRESOR. EL CONTROLADOR (111) CONSTA ADEMAS DE UNA PANTALLA DE VISUALIZACION DEL ESTADO (104) PARA INDICAR LAS FUNCIONES DEL COMPRESOR, CONEXIONES A UNA ALARMA QUE SE ACTIVA EN EL CASO DE QUE HAYA UNA FALLA EN EL COMPRESOR, UN CONMUTADOR PARA INICIAR UNA AUTOCOMPROBACION DEL CONTROLADOR Y UN CIRCUITO PARA UN CAMPO APLICADO AL RELE DETECTOR DE CORRIENTE.
