7.1.6 ERROR HISTORY
How to display the error history
Use the dedicated remote control unit for service.
Press the ESC then CHP/TIM keys. The measured error rate value, results of self-diagnosis, and time data read from the
real-time clock are displayed on the screen, as shown below:
How to translate the indications of the error history
The 2-digit hexadecimal number (F8, C3 or F8, in the above example) represents an error code, and the subsequent time
indication (000123:45, 000079:41, or 000052:17, in the above example) represents the accumulated power-on time when
a respective error was generated. The 2-digit number following the time indication is the number of times the respective
error was generated. As to an error that was generated consecutively several times, the time indication is that for the last
one. The bottom two lines are used for indicating the meaning of the latest error.
In the above example,
• An F8 error (loading error) was generated twice consecutively, and the accumulated power-on time upon generation of the
second F8 error was 52 hours 17 minutes.
• Then a new error (C3: detection of the tracking excess current) was generated consecutively three times, and the
accumulated power-on time upon generation of the last C3 error was 79 hours 41 minutes.
• A new F8 error (loading error) was generated at 123 hours 45 minutes.
Specifications of storage of the error history
If the same error is consecutively generated, as shown in the above example, the error counter counts the number of times
it was generated, and the last generation time is stored in memory (as shown with the first F8 error generated twice).
If another type of error is generated, its error code and time of generation are separately stored in memory. If that error is
generated consecutively several times, the error counter counts the number of times it was generated, and the latest
generation time is stored in memory (as shown with the second C3 error generated three times). Then if any error other
than C3 is generated, its error code and time of generation are separately stored in memory, even if the same error code
(F8 error, in the above example) already exists in the error history.
A maximum of 16 logs of errors can be recorded. The maximum count of generations per log is 255. In the above example,
3 logs are recorded (nonconsecutive F8 errors that were generated for the first and third times are counted as two errors.)
If the error count exceeds 16, the oldest error will be erased each time a new error is added.
As the maximum number of errors that can be displayed on one page is 8, if the number of errors is 9 or more, switch
between Page 1 (No. 1-8 logs) and Page 2 (No. 9-16 logs) by pressing the CHP/TIM key.
Press the CHP/TIM key again to display the detailed information of the error history and results of self-diagnosis.
In the example below, the part enclosed with the solid line ( ) is the error history, and the part enclosed with the
dotted line ( ) is the results of self-diagnosis. (For details on the results of self-diagnosis, see "Self-diagnosis.")
