PURPOSE:To make it possible to grasp accurately the range a trouble influences, by providing a diagnostic-program all-starting switch and all-stopping switch and by fitting respective display lamps and switches to the same operation board. CONSTITUTION:Diagnostic-program all-starting switch 3, when operated simultaneously with either switch 21 or 22 combinationally used for a trouble display lamp, starts an automatic program. Diagnostic-program all-stopping switch 4, when operated, stops the automatic diagnostic program forcibly. When a trouble is detecfted, several lamp-switches come on displaying a suspected range through the operation. The range is shown by two-dot chain lines. At this time, a more suspicious switch between lighting switches 21 and 22 is operated simultaneously with switch 3 to start the corresponding diagnostic program. As a result, if not the position of the trouble is discriminated, the position can be found rapidly. |
