7.1.6 ERROR LOG DISPLAY

How to display the Error log
• Start the PRV-LX10 and let it run idle (in the state in which the Function menu is not displayed and neither recording nor
playback is performed).
• On the remote control unit for service, press the [ESC], [TEST], [REP.A], and [8] keys, in that order.
The error log for Drive 1 is displayed.
• To display the error log for Drive 2, press the [ESC], [TEST], [REP.A], and [9] keys, in that order.
Outline of the Error log
Up to 8 error records (16-byte data per record) are held for each drive (see Table 1 "Error record"). If there are more than 8
errors, the oldest record is deleted each time a new one is logged.
Description of the Error log
The order of error generation and error codes are described here.
1. Order of error generation
One byte of data at the beginning of each record (Byte 0) is called the Identity code. The Identity code of the latest record is
FFh, and for other records it is 00h. However, if an error is generated for the first time after the power was turned on, FFh is
rewritten as BBh. Therefore, from the record having "FFh" Identity code back to the record immediately before that having
"BBh" as its Identity code are the error records generated from the latest power-on until the present (or the latest power-off).
Note: At the initial setting, all codes of any record are set FFh. If all codes in a record are FFh, it means that the record has
no valid data.
2. Error codes
At Byte 7 of each record, an error code is stored. For details on error codes, see Table 2. Ignore any record whose code for
Byte 8 (execute task) is 88h, because it means that the record is for obtaining data on internal status.
Note: The data displayed on the error-log screen are directly dumped from the error-log data stored in memory for the drive,
and no process (including data sorting) is added on the part of the PRV-LX10 application.
