SELF DIAGNOSIS FUNCTION
[SELF DIAGNOSTIC SCREEN DISPLAY]
• Panel Operation Time is recorded every 30 min,
but Total Operation Time is recorded every 1 hr .
Therefore, the panel op. time might become larger than the total op. time.
Format of error timestamps
YYMMDDhhmmss (in UTC)
Example:
120823132523 -> Aug 23 2012 13:25:23 UTC
* Only when time is set, an error timestamp
is saved.
Since the diagnostic results displayed on the screen are not automatically cleared,
always check the self-diagnostic screen. After you have completed the repairs, clear the result display to “0”.
