FIRSTOUT SHUTDOWN TRACING FOR FUEL PROCESSOR CONTROL SYSTEM

摘要

A METHOD AND APPARATUS FOR DETERMINING WHICH CONDITION IN A FUEL PROCESSOR HAS INITIATED A SHUTDOWN OF THE FUEL PROCESSOR ARE DISCLOSED. IN GENERAL, THE APPARATUS GENERATES A PLURALITY OF SHUTDOWN INITIATOR SIGNALS (402), EACH CORRESPONDING TO ONE OF A PLURALITY OF SHUTDOWN CONDITIONS AND INDICATING WHETHER SUCH CONDITION IS PRESENT. THE SHUTDOWN INITIATOR SIGNALS ARE READ WITHIN A PREDETERMINED WINDOW. AT LEAST ONE OF THE READ SHUTDOWN INITIATOR SIGNALS INDICATES THAT A CORRESPONDING FIRST SHUTDOWN CONDITION HAS OCCURRED AND IDENTIFIES THE CORRESPONDING FIRST SHUTDOWN CONDITION AS THE FIRSTOUT.
