Operation of the Industrial PC
The front of the PC has a lockable front cover, behind which operating
elements and LED's are located. There is a number on the lock.
If the key is lost, the number on the lock can be used to order a
replacement.
Operating and LED's
behind the front cover
Switching on The Industrial PC has its own ON switch (see photo above), although this
can optionally be configured to have no function.
Reset key At the top left behind the front panel there is a reset button with which the
system can be re-booted (see photo above).
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 the software
must also be unable to switch the Industrial PC off, since data can be lost
from the hard disk by switching off while the software is running.
If the Industrial PC is switched off while the software is writing a file to the
hard disk, this data can be damaged. Control software generally writes files
such as logs to the disk of its own accord at intervals of just a few seconds,
which means that the probability of damage is quite high if the computer is
switched off while the software is running.
KeyLock A keyboard switch above the mains switch allows a connected PC
keyboard to be switched off.
LED's There are two LED's behind the front cover. The yellow LED indicates hard
disk activity, while the green LED indicates that the power is switched on.
