3.4.1 Beckhoff power supply technology

Schematic diagram of
power supply unit wirings

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. Via the
PC ON-input of the power supply the PC gets the command to shut down the operating system.

Once the PC has shut down, the PC power supply unit sets the Power Status-output (P-S) to 0, what
indicates 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. The battery will only be used in the event of
a power failure.

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 27 V / 1.4 A (max. 2.5 A from 2016 and later), for connecting a

Installation

C5240 19

Control Panel with a display dimension up to 19 inches. This enables a power failure to be visualized and
displayed to the user. Once the PC has shut down, the UPS output is switched off.

For a detailed functional description please refer to section Connecting Power Supply.

3.4.5 Connecting Power Supply

The external wiring consists of the connection of the power supply, the battery pack (optional) and the
connection of customized components for shutting down the PC.

Cable Cross Sections

For the connection of the power supply, wiring with a cable-cross-section of 1.5 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.

Attention

Insert fuse

The power supply must be protected with maximum 16 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.

Attention

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-energizing the whole system. The
maximum load for the Power Status output is 0.5 A and a suitable fuse should be provided.

UPS output

In order to maintain a screen display for the PC in the event of a power failure, the power supply unit is
equipped with a UPS output for connecting a Control Panel. The maximum load for the output is 1.4 A
(max. 2.5 A from 2016 and later).

UPS output function

• The 24 V DC connection at the UPS output is live even after a power failure. The maximum load
is 1.4 A (max. 2.5 A from 2016 and later).

• Once the PC has been de-energized via the UPS software, the UPS output is switched to 0 V.
Any connected panel is thus switched off, and total discharge of the rechargeable battery is
prevented.

1. Check that the external power supply is providing the correct voltage.

2. Insert the power supply cable that you have assembled into the Industrial PC's power supply
socket. Then connect it to your external 24 V power supply.

Attention

Use same type of rechargeable battery

If a 24 V UPS is installed, the same type of rechargeable battery must be used.

Operating Instructions

24 C5240

4 Operating Instructions

4.1 Switching the Industrial PC on and off

4.1.1 Switch on

The Industrial PC has its own mains switch. The Industrial PC will start when the main switch switched
on.

4.1.2 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.

Attention

First shut down, then switch off the PC

If the Industrial PC is switched off as the software is writing a file to the memory drive,
the file will be destroyed. Control software typically writes something to the memory
drive every few seconds, so that the probability of causing damage by switching off
while the software is running is very high.

Attention

Switch off power supply

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.

4.1.3 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.
