D. Self-Test (System-Detected Troubles)1.00 Error Record Display1.01 Start Time of Self-TestBuilt-in diagnostic test program of the systemmonitors the troubles generated by hardware orsoftware. To perform the self-test, assign thedesired start time of self-test in “System-Operation” Start Time of Test.Be careful not to access the system during thistest.Refer to Section 10-C-4.00 “Operation (OPR)” forprogramming.1.02 Error LogWhen a system maintenance object begins to failperiodic testing, the system automaticallygenerates an error record. (Refer to Section 14-G-2.00 “Error Log screen.”)Depending on the severity, the record is stored inone of two tables in the Error Log.The two tables are:Error Log (1/2) (Major and Minor Alarm)Up to 15 major or minor error records are storedin this error log.The error tables are organized bytime of occurrence.The newest error recordappears on the top of the screen.If more than 15 errors have occurred in that time,error records already stored in the error log willbe overwritten, starting with the first.Error Log (2/2) (Light Alarm)Up to 15 light error records can be stored in thiserror log.Other conditions are the same as error log (1/2)Each error log screen (1/2)(2/2) existsindependently.The error log is accessible by entering thefollowing command.Command FormatOPE>ERR + Index + (Item)(Index)0 : Clears all error messages in the Error Log(1/2) (2/2)1 : Displays error messages in the Error Log(1/2)(Major and Minor Alarm)2 : Displays error messages in the Error Log(2/2)(Light Alarm)(Item)1 : Read only2 : Displaying and clearing error log recordsThe error log is comprised of the following twoerror tables.Error Log (1/2) (Major and Minor Alarm)Error Log (2/2) (Light Alarm)Refer to Section 14-G-2.00 “Error Log Screen.”1.03 Printing out the AutomaticFailure ReportingThe error log records can be printed out.First connect the printer to the SIO #2 port on theMain Unit using RS-232C cable, then set“System Operation” Print Error Log to “Y.”Refer to Section 10-4.00 “Operation (OPR) forProgramming.”Command FormatPRG>OPR AT 215-D-1
