<p>PURPOSE:To preferentially check a sensor input system in which an abnormal state has occurred by providing a means for checking preferentially an input system of an abnormality signal in a non-work state against the other input system. CONSTITUTION:At the time of checking an abnormal state diagnosis, for instance, in case a grain straw sensor 11c has become a turn-on state, since it cannot be considered that the grain straw sensor 11c becomes a turn-on state in a non-work state, a CPU 16 of a checker 15 judges that this turn-on state is an abnormal state against condition setting. Subsequently, when it is judged that a thresh sensor 11a and a direction sensor 11b are in a normal state, the CPU 16 gives priority to the check sequence of the grain straw sensor 11c of the post-sequence rather than the sensors 11a, 11b of the pre-sequence and displays a result of check on a display part 3, and also, displays simultaneously a discrimination symbol of a fact of a priority check, as well.</p> |
