Machine manufacturer
Via machine data the machine manufacturer can configure whether, after
restart of the control, the workpiece last active is to be loaded again when the
control is switched on. However, before switching off the control a workpiece
must have been loaded and selected. On restart of the control the workpieces
are loaded one after the other starting with the workpiece in channel 1 to
channel n. Generally, the STANDARD workpiece is loaded first.
Before switching off the power supply the control must always be "powered
down" in order to assure the integrity of the file system on the hard disk and
avoid loss of data.
The control is powered down by selecting the EXIT command in the menu.

SYSTEM DOWN query
The power supply may only be switched off when the above safety prompt has
been confirmed with "Yes" and the "SYSTEM DOWN" screen has appeared.
Important
Never switch the power supply off during normal operation. The control must
always be "powered down" by selecting the End command in the Diagnosis
menu before it is switched off.
Note
If Windows is to be closed during an active application, the system modal box
cannot be acknowledged with the NC keyboard. This is possible only with an
MF2 keyboard.
