The Panel PC does not have its own mains power switch. As soon as the power supply is switched on the
Panel PC is activated.

Shutting down and switching off

Control software such as is typically used on Industrial PCs permits various users to be given different rights.
A user who may not close software may also not switch the Industrial PC off, since data can be lost from the
storage medium by switching off while software is running.

NOTE

First shut down, then switch off!

If the Industrial PC is switched off as the software is writing a file to the storage medium, the file will be de­stroyed. Control software typically writes something to the storage medium every few seconds, so that the
probability of causing damage by switching off while the software is running is very high.

NOTE

Switch off power supply

When you have shut down the Industrial PC, you have to switch off power supply for at least 10 seconds
before rebooting the system.
After resetting power supply the Industrial PC will start booting automatically.

6.2 Touch screen

The operation of the Panel PC occurs via the Touch Screen.

NOTE

Risk of damaging the Touch Screen

The touch screen may only be actuated by finger tips or with the touch screen pen. The operator may wear
gloves but there must be no hard particles such as metal shavings, glass splinters embedded in the glove.

NOTE

Properly installation of the system and the multi-touch device

Capacitive Touch Screens use the functional principle of capacitive alternation of the electrical field. Strong
electrical fields can influence the functionality of the multi-touch devices.
To ensure the correct function of the Touch Screen take care of a standardized installation of all parts of the
system and an EMC-environment conforming to standards.
