Clearing errors
Clearing errors outside of the error window
Clear the errors/messages in the header: Press
the CE key
In some operating modes (such as the Editing
mode), the CE button cannot be used to clear the
error, since the button is reserved for other functions.
Deleting errors
Open the error window
Clear individual errors: Position the highlight on the
error message and press the
DELETE soft key.
Delete all error messages: Press the DELETE ALL
soft key.
If the cause of the error has not been removed, the
error message cannot be deleted. In this case, the
error message remains in the window.
Error log
The TNC stores errors and important events (e.g. system startup)
in an error log. The capacity of the error log is limited. If the log is
full, the TNC uses a second file. If this is also full, the first error log
is deleted and written to again, and so on. To view the error history,
switch between
CURRENT FILE and PREVIOUS FILE.
Open the error window.
Press the
LOG FILES soft key.
Open the error log file: Press the
ERROR LOG soft
key.
If you need the previous log file: Press the
PREVIOUS FILE soft key.
If you need the current log file: Press the
CURRENT FILE soft key.
The oldest entry is at the beginning of the log file, and the most
recent entry is at the end.
