3.3.1 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

C6915 13

Installation 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 for connecting a 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

3.3.2 Fitting the cable

Fit the cables for the power supply of the Industrial PC, the connection of the battery pack as well as the connection of the power-switch in accordance with the wiring diagram, using the included material for assembling the connectors.

3.3.2.1 Material for assembling the connectors

Plug connector 8-pole, Strain relief housing with lacing cord

3.3.2.2 Assembling the connectors

The connector is specified for 16 A and can lift conductive cross-sections until 1.5 mm

So the connector is fitted to the cable:

1. Strip insulation from the cable ends (Length of stripped conductor is 8 – 9 mm).

2. Screw together the cable ends in the 8-pole plug connector in accordance with wiring diagram.

Thread the lacing cord into that lower part of the strain relief housing.

Put the plug connector into that lower part of the strain relief housing.

Tighten the lacing cord and pinch off the plastic strap.

Fix the upper part of the strain relief housing by snapping it onto the lower part.

Installation

3.3.3 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.

3.3.3.1 Cable Cross Sections

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

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.

Insert fuse

Attention

The power supply must be protected with maximum 16 A.

3.3.3.2 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.

3.3.3.3 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

Attention

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.

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.

3.3.3.5 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.

• 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.
