Abstract

A display screen switches between a monitor display and a trouble display. If a pause switch on the trouble display is operated, the display screen will be fixed to the trouble display for a prescribed time. The display screen can be set to the trouble display until a restart or release switch on the trouble display screen is operated. The monitor display and the trouble display can be cyclically displayed. During cyclical display, a jump switch on the trouble display can be operated, so that the display device will be returned to the monitor display from the trouble display, where the monitor display can be displayed for a prescribed time (for instance, 5 minutes). In addition, a cancel switch on the trouble display can be operated, so that the display screen may be kept returned to the monitor display.
