• a basic data display control unit for outputting display signals of the basic data based on the status variables detected by said detection means so as to display the basic data on said basic data display area of said usual screen;
• an alarm display control unit for determining, based on the status variables detected by said detection means, whether the status variables indicate an alarmed state and outputting alarm display signals when the status variables are determined as indicating the alarmed state, so as to display the alarm mark on said alarm display area on condition that said usual screen is not shifted;
• a failure display control unit for determining, based on the status variables detected by said detection means, whether the status variables indicate a failed state of said detection means and outputting failure display signals when the status variables are determined as indicating the failed state, so as to display the failure code on said failure display area on condition that said usual screen is not shifted;
• and
• a screen display control unit for shifting said usual screen displayed in said display unit in response to manipulation by an operator to an alarm list screen for displaying a list of current and past alarms, or to a failure list screen for displaying a list or current and past failures.
