PURPOSE:To accurately distinguish a suspected package to efficiently perform the recovery work by providing maintenance replacement units to which numbers are electrically set and displaying the package, where the occurrence of trouble is suspected, with the package name and the mounting position. CONSTITUTION:If trouble occurs, a diagnostic processor 7 is started to successively diagnose electric circuit packages A1-D6 provided with serial electric switches which electrically set the sequential number; and if trouble in packages A1 and B2 is suspected, numbers set by serial number switches 1a and 2b of both packages are read and are stored as the error log in the storage part of the diagnostic processor 7 together with package names and mounting positions, and they are displayed on a display part simultaneously. In accordance with this display, these packages are successively replaced with packages A'10 and B'20 for maintenance to finally confirm the trouble position by the diagnostic processor 7. |
