Switching the Panel PC on and off
Switch 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.
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).
Warning
First shut down, then switch off the Panel PC!
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.
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.
