Operating Instructions
5 Operating Instructions
5.1 Switching the Panel PC on and off
5.1.1 Switching on
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.
5.1.2 Shutting down and switching off
Control software, as typically applied in Industrial PCs, enables the assignment of different rights to all
users. A user who is not entitled to shut down the software may not switch off the Panel PC as an attempt
to shut it down when the software is running could result in the loss of software data on the Compact
Flash memory card (CF card).
First shut down, then switch off!
Warning
If the Panel PC is shut down while the software is writing a file onto the CF Card
memory card, the file will be destroyed. Control software typically writes something to
the CF card every few seconds, so that the probability of causing damage by switching
off while the software is running is very high.
Switch off power supply
Warning
When you have shut down the Panel PC, you have to switch off power supply for at
least 10 seconds before rebooting the system.
After resetting power supply the Panel PC will start booting automatically.
5.2 Operation
The operation of the Panel PC occurs via the Touch Screen.
Risk of damaging the Touch Screen
Warning
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.
