Switch-off
To prevent data being lost at switch-off, you need to shut down the
operating system as follows:
8 Select the Manual Operation mode.
8 Select the function for shutting down, confirm again
with the YES soft key.
8 When the TNC displays the message NOW IT IS SAFE
TO TURN POWER OFF in a superimposed window, you
may cut off the power supply to the TNC.
The reference points need only be traversed if the
machine axes are to be moved. If you intend only to write,
edit or test programs, you can select the Programming
and Editing or Test Run modes of operation immediately
after switching on the control voltage.
You can traverse the reference points later by pressing
the PASS OVER REFERENCE soft key in the Manual
Operation mode.
Inappropriate switch-off of the TNC can lead to data loss.
