Caution: hazard to the user!
Machines and machine components always pose mechanical
hazards. Electric, magnetic, or electromagnetic fields are
particularly hazardous for persons with cardiac pacemakers or
implants. The hazard starts when the machine is powered up!

Read and follow the safety precautions and safety symbols
Use the safety devices
Refer to your machine manual.
Switching on the machine and traversing the reference
points can vary depending on the machine tool.

Switch on the power supply for the control and the machine
The control displays the switch-on status in the subsequent
dialogs.
If booting was successful, the control displays the Power
interrupted dialog

The control displays the Compiling PLC
program dialog; the PLC program is compiled

The control carries out a self-test.
If the control does not register an error, it displays the Traverse
reference points dialog.
If the control registers an error, it issues an error message.
Danger of collision!
When the machine is switched on, the control tries to restore
the switch-off status of the tilted plane. This is prevented under
certain conditions. For example, this applies if axis angles are
used for tilting while the machine is configured with spatial angles,
or if you have changed the kinematics.
If possible, reset tilting before shutting the system down
Check the tilted condition when switching the machine back on
