Operating Instructions

Please also refer to chapter Foreword.

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.

First shut down, then switch off the PC

Attention

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.

Switch off power supply

Attention

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.
