Beckhoff power supply technology
Schematic diagram of
power supply unit wirings
Innovative solution for
shutting down Industrial
PCs
Industrial PCs equipped with a UPS are in actual use frequently switched
off by simply turning off the supply voltage. In this case the PC shuts down
via the battery. However, over time this reduces the service life of the
battery.
The new Beckhoff power supply technology approach addresses this
problem and now offers the user the option of switching the PC off without
the need for using the battery, thereby reducing the load on the battery.
In addition to the main switch this innovative solution uses an ON/OFF
switch for the machine. Basically, the main switch remains switched on and
provides the power supply for the PC during shutdown.
Once the PC has shut down, the PC power supply unit issues a signal to
indicate that the process is complete and that the main voltage can be
switched off. This can be done manually via a signal lamp connection or
via a contactor. With this solution the main switch generally only has to be
switched off if the control cabinet has to be opened.
14 CP72xx

Installation Instructions
In order to maintain a screen display for the Industrial PC in the event of a
power failure, the power supply unit is equipped with a UPS output for
connecting a Control Panel. This enables a power failure to be visualised
and displayed to the user. Once the PC has shut down, the UPS output is
switched off in order to avoid total discharge of the battery.
The UPS output of the CP72xx power supply unit is internally connected
with the panel
For a detailed functional description please refer to section Connecting
Power Supply.

16 CP72xx

Installation Instructions
The external wiring consists of the connection of the power supply, the
battery pack (optional) and the connection of customised components for
shutting down the PC.
Note cable cross sections,
avoid voltage drop!
For the connection of the power supply, wiring with a cable-cross-section
of 1.0 mm2 must be used.
With bigger distances between voltage source and PC, you take the
voltage drop as a function of the cable-cross-section as well as voltage
fluctuations of your distribution voltage into account, so that is secured that
the voltage doesn't fall under 22 V at the power supply.
The power supply must be protected with maximum 10 A.
Configuration for shutting down the PC
The connections for shutting down the Industrial PCs are established via
the PC_ON input and the Power Status output.
PC_ON and Power Status functions
• If the PC_ON input is connected to 24 V via a switch, the PC shuts
down according to the rules. The PC_ON signal is inverted, i.e. the
PC shuts down if the 24 V connection is live.
• If the PC_ON input is NOT connected by the user, the PC can be
booted in the familiar way by connecting the supply voltage and shut
down via the battery by switching off the supply voltage.
Service life of the rechargeable battery
This procedure significantly reduces the service life of the rechargeable
battery and should therefore not be used.
• Once the PC has shut down, the Power Status output is switched
from 24 V to 0 V. Via this output a signal lamp can be connected or a
contactor for de-energising the whole system. The maximum load for
the Power Status output is 0.5 A and a suitable fuse should be
provided.

Operating Instructions
Please also refer to chapter Foreword.
Switching the Industrial PC on and off
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
If the Industrial PC is switched off as the software is writing a file to the
storage medium, the file will be destroyed. Control software typically writes
something to the storage medium every few seconds, so that the
probability of causing damage by switching off while the software is
running is very high.
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.
