Abstract

PURPOSE:To easily judge the trouble parts and to improve the working efficiency of an abnormality display device by displaying successively the abnormality contents and the abnormality occurring frequency in the order of abnormality occurring frequencies of a storage means for each operation of a check switch. CONSTITUTION:A remote controller 1 is connected to an equipment main body 2 via a connection cable 3. A microcomputer 6 judged a trouble occurred in a control circuit component element 5 and increases (+1) the corresponding abnormality occurring frequency storage area of a storage means 7. Then the computer 6 sends the error packets to the controller 1 in the order of higher occurring frequencies of abnormality every time a check switch 10 is pushed. Then the abnormality contents and occurring frequencies are successively displayed on a display means 11 in the order of occurrence of abnormality. Thus it is possible to easily recognize the occurrence of troubles and their areas when these troubles are repaired and inspected.
