Operating Instructions
Operating Instructions
Switching the Industrial PC on and off
Switch on The Industrial PC does not have its own mains switch. The Industrial PC
will start when the equipment is switched on, or when it is connected to the
power supply.
Shutting down and
switching off When the plant is switched off, or when it is disconnected from its power
supply, the Industrial PC will be switched 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 hard
disk by switching off while software is running.
Warning
First shut down, then switch off the PC!
If the Industrial PC is switched off as the software is writing a file to the
hard disk, the file will be destroyed. Control software typically writes
something to the hard disk 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 Industrial PC, you have to switch off power
supply for at least 10 seconds before rebooting the system.
After resetting power supply the PC will start booting automatically.
First switching on and driver installation
When you switch on the Industrial PC for the first time, the pre-installed
operating system (optional) will be started. In this case, all the required
drivers for any additional, optional hardware components ordered with the
PC will already have been installed.
If the PC was ordered without operating system, you have to install the
operating system and the driver software for any auxiliary hardware
yourself. Please follow the instructions in the documentation for the
operating system and the additional devices.
