Overwrite protection for datum
Row 0 in the preset table is write-protected. The TNC saves the
last manually set datum in row 0.
You can protect further rows in the preset table from being
overwritten with the
LOCKED
column. The write-protected rows
are color-highlighted in the preset table.
If you want to overwrite a write-protected row with a
manualprobing cycle, confirm with
OK
and enter the password
(wherepassword-protected).
Caution: Data may be lost!
If you forget the password, then you can no longer
reset the write protection in a protected row.
If you protect a row with a password, please make a
note of this password.
Ideally, use simple protection with the
LOCK /
UNLOCK
soft key.
Proceed as follows to protect a datum from overwriting:
Press the
CHANGE PRESET
soft key
Select the
LOCKED
column
Press the
EDIT CURRENT FIELD
soft key
Protection for datum without using password:
Press the
LOCK / UNLOCK
soft key
The TNC writes an

in the
LOCKED
column.
Protect a datum with a password:

LOCK / UNLOCK PASSWORD
soft key
Enter the password into the pop-up window
Confirm with the

soft key or with the
