PURPOSE: To provide a dual system which can directly and accurately detect faults. CONSTITUTION: The output of a buffer 17 is returned to the system controllers 12a and 12b via a buffer 18. A comparator 16a compares the output of a buffer 15a with that of the buffer 18, and a comparator 16b compares the output of a buffer 15b with that of the buffer 18 respectively. Then both comparators 16a and 16b output the error signals to a CPU respectively when no coincidence of outputs is secured by both comparators. |
