When a part of a display part on the monitor display screen 11 is shifted to, for instance, the first trouble display 21 (step 102), if a pause button 21f on the first trouble display 21 is touched (step 103) as shown in FIG. 1(a), a part of the display part on the monitor display screen 11 will be fixed to the first trouble display 21 (step 104) for a prescribed time (for instance, 2 minutes). Then, when the prescribed time elapses, the display part on a part of the monitor display screen 11 is sequentially shifted to a next second trouble display 22 and a third trouble display 23 and returned to the monitor displays 11c and 11d (step 101).
In another embodiment, if a pause button 21f on the trouble display screen 21 is touched as shown in FIG. 2(a) (step 103), the display part on a part of the monitor display screen 11 will be shifted to a trouble display screen 21′ shown in FIG. 2(b), the pause button 21f will be changed to a restart button 21h and the display color of the button 21h will be changed to red (it is shown by broken lines). Then, the display screen is fixed to the first trouble display screen 21′ (step 104) until the restart button 21h on the trouble display screen 21′ is operated. When the restart button 21h on the trouble display screen 21′ is touched, the display part on a part of the monitor display panel is returned again to the monitor displays 11c and 11d (step 101).
In the above-described fifth embodiment, as shown in FIG. 5, the first trouble display 21, the second trouble display 22 and the third trouble display 23 are displayed on parts corresponding to the display parts 11c and 11d of the display parts 11a to 11d on the monitor display screen 11.
For example, the first trouble display 21, the second trouble display 22 and the third trouble display 23 may be displayed in the parts corresponding to the display parts 11a and 11b of the display parts 11a to 11d on the monitor display screen 11.
Further, the first trouble display 21, the second trouble display 22 and the third trouble display 23 may be displayed on the parts corresponding to the display parts 11c and 11d of the display parts 11a to 11d on the monitor display screen 11 and the monitor displays 11c and 11d may be displayed on the parts corresponding to the display parts 11a and 11b.
For example, when the first trouble display 21 is shown, the first trouble display 21 may be displayed on the parts corresponding to the display parts 11c and 11d of the respective display parts 11a to 11d on the monitor display screen 11. When the second trouble display 22 is displayed, the second trouble display 22 may be displayed on the parts corresponding to the display parts 11a and 11b of the display parts 11a to 11d on the monitor display screen 11.

For example, when the display screen of the monitor panel is shifted to the first trouble display screen 21 (step 202), if a jump button 21g on the first trouble display screen 21 is touched as shown in FIG. 2(a) (step 203), the display screen of the monitor panel will be returned to the initial monitor display screen 11 as shown by an arrow mark 31 indicated by broken lines in FIG. 9 and the display screen is fixed to the monitor display screen 11 for a prescribed time (for instance, 5 minutes) (step 204). Then, when the prescribed time elapses, the display screen of the monitor panel shifts to the first trouble display screen 21 from the monitor display screen 11 as shown by an arrow mark 32 indicated by broken lines in FIG. 9. Subsequently, the display screen is sequentially shifted to the second trouble display screen 22 and the third trouble display screen 23 (step 205), and then, returned to the monitor display screen 11 (step 201).
When a jump button 22g on the second trouble display screen 22 is touched (step 203) while the second trouble display screen 22 is displayed on the monitor panel, the display screen of the monitor panel is returned to the initial monitor screen 11 as shown by an arrow mark 33 indicated by broken lines in FIG. 9 and the display screen is fixed to the monitor display screen 11 for a prescribed time (for instance, 5 minutes) (step 204). When the prescribed time elapses, the display screen of the monitor panel is shifted to the second trouble display screen 22 as shown by an arrow mark 34 shown by broken lines in FIG. 9. Similarly, when a jump button 23g on the third trouble display screen 23 is touched (step 203) while the third trouble display screen 23 is displayed on the monitor panel, the display screen of the monitor panel is returned to the initial monitor screen 11 as shown by an arrow mark 35 indicated by broken lines in FIG. 9 and the display screen is fixed to the monitor display screen 11 for a prescribed time (for instance, 5 minutes) (step 204). When the prescribed time elapses, the display screen of the monitor panel is shifted to the third trouble display screen 23 as shown by an arrow mark 36 shown by broken lines in FIG. 9.
In another embodiment, a cancel button 21e on the second trouble display screen 21 is touched as shown in FIG. 1(a), so that the display screen of the monitor panel can be kept returned to the monitor display screen 11 from the first trouble display screen 21. In this case, when the engine key is restarted, a cyclic display shown in FIG. 9 can be resumed by carrying out a special operation.
In the ninth embodiment of the invention, it is supposed that a case in which a monitor display screen 11 and a trouble display screen 21 are alternately displayed on a monitor panel as shown in FIG. 8 is used (steps 201 and 202). For example, when the display screen of the monitor panel is shifted to the trouble display screen 21 (step 202), if a jump button 21g on the trouble display screen 21 is touched as shown in FIG. 2(a) (step 203), the display screen of the monitor panel will be returned to the initial monitor display screen 11 as shown by an arrow mark 31 indicated by broken lines in FIG. 8 and the display screen is fixed to the monitor display screen 11 for a prescribed time (for instance, 5 minutes) (step 204). Then, when the prescribed time elapses, the display screen of the monitor panel shifts to the trouble display screen 21 from the monitor display screen 11 as shown by an arrow mark 32 indicated by broken lines in FIG. 8, and then, returned to the monitor display screen 11 (step 201).
