PURPOSE:To shorten the time required for a retrieval and a preservation work of a faulty part by providing a flip-flop for holding a system fault at every system fault, and an indicator, and displaying the cause of a falut when an EMA circuit has been started. CONSTITUTION:In case a system fault A is detected, it is converted to a pulse signal by a differentiating circuit 1, held by a flip-flop 11, and the system fault a is displayed by a display device 14. Reset of the flip-flop 11 is generated by a software instruction of a central control device 15 or a key operation, and executed through a reset signal line 16. With regard to system faults B, C and other fault, too, they can be explained in the same way. |
