Switching the Industrial PC on and off

Notice

Public networks

Connecting the PC to public networks without additional protective measures can compromise the safety of the device.

  • Protect the PC before connecting it to public networks.

Notice

Data loss due to switching off the PC while the software is running

Switching off the PC before the running software is terminated and the operating system is shut down can lead to data loss.

  • Quit the running software and shut down the operating system before switching off the PC.

Notice

Data loss due to switching off the power supply when the UPS battery is empty

Switching off the power supply when the UPS battery is empty can lead to data loss, as the operating system cannot be shut down properly without battery power.

  • Ensure that the UPS battery is charged in the event of a power failure.
  • For UPS C9900-P209 and C9900-U209, charge the battery exclusively via the switched-on PC. Never connect a charger.

Notice

Shortened battery life due to switching off the power supply

If the power supply is simply switched off, the operating system shuts down via the battery. With daily use, this significantly shortens the life of the battery.

  • Avoid switching off the power supply before shutting down the operating system.
  • Use the PC-ON input (see the following description) to shut down the operating system in a battery-friendly manner.

Switch on and off with 100-240 V power supply unit

The industrial PC is started or switched off when the system is switched on or off or when the power supply to the industrial PC is connected or disconnected. Behind the front flap of the industrial PC there is an ATX push button. You can use it to control the startup and shutdown of the operating system. If you press the ATX push button briefly while the Windows operating system is running, the operating system shuts down. You can switch off the supply voltage after shutdown or restart the PC by pressing the ATX push button again.

You can restart the device via the reset button behind the front flap of the industrial PC. Without shutting down the operating system in advance, there is a risk of data loss.

If you have ordered your industrial PC with a 110 V or 230 V UPS, this enables data backup in the event of a sudden switch-off of the device. If the power supply or the system is switched off before you have shut down the operating system properly, the operating system shuts down using the battery. Data can be saved. With frequent use, this shortens the life of the battery.

Switching on and off with 24 V power supply unit without UPS

If you have ordered your industrial PC with a 24 V power supply unit without integrated UPS instead of a 100-240 V power supply unit, the industrial PC has a power supply socket (X101) and a socket for external wiring (X102). The socket for external wiring contains an input PC-ON and an output Power Status.

You can use the PC-ON input to control the startup and shutdown of the operating system as an alternative to the ATX push button. The PC-ON signal is inverted, which is why the operating system boots up at 0 V at the input and shuts down at 24 V. During operation, 0 V must therefore be permanently applied to the input. If you want to shut down the operating system, you must apply 24 V to the PC-ON input. Once the operating system has shut down, the PC power supply unit sets the Power Status output from 24 V to 0 V. This indicates that the shutdown is complete and you can turn off the power supply. You can then switch off the power supply. If you remove the 24 V from the PC-ON input before you have switched off the power supply, the operating system restarts. Therefore, 24 V must be applied to the input until you have switched off the power supply.

Besides the main switch of the machine, you can also install an additional ON/OFF switch to turn the machine on and off. The main switch can thus remain switched on in principle and thus ensures that the PC is still supplied with power during the shutdown of the operating system. Via the Power Status output, you can switch, for example, a contactor that switches off the entire system. The load capacity of the Power Status output is limited to max. 0.5 A. No fuse protection is required.

You can use the UPS output to supply another device, such as a control panel as an operating element. If the power supply fails without a UPS, both the industrial PC and devices supplied via the UPS output are switched off directly.

Switching on and off with 24 V power supply unit with UPS

If you have ordered your industrial PC with a 24 V power supply unit with integrated UPS instead of a 100-240 V power supply unit, the industrial PC has a power supply socket (X101) and a socket for external wiring (X102). You can connect an external battery pack to the industrial PC via the voltage socket. The socket for external wiring contains an input PC-ON and an output Power Status.

You can use the PC-ON input to control the startup and shutdown of the operating system as an alternative to the ATX push button. The PC-ON signal is inverted, which is why the operating system boots up at 0 V at the input and shuts down at 24 V. During operation, 0 V must therefore be permanently applied to the input. If you want to shut down the operating system, you must apply 24 V to the PC-ON input. Once the operating system has shut down, the PC power supply unit sets the Power Status output from 24 V to 0 V. This indicates that the shutdown is complete and you can turn off the power supply. You can then switch off the power supply. If you remove the 24 V from the PC-ON input before you have switched off the power supply, the operating system restarts. Therefore, 24 V must be applied to the input until you have switched off the power supply. If you switch off the power supply before you have shut down the operating system properly, it shuts down using the battery. With frequent use, this shortens the life of the battery.

Besides the main switch of the machine, you can also install an additional ON/OFF switch to turn the machine on and off. The main switch can thus remain switched on in principle and thus ensures that the PC is still supplied with power during the shutdown of the operating system. Via the Power Status output, you can switch, for example, a contactor that switches off the entire system. The load capacity of the Power Status output is limited to max. 0.5 A. No fuse protection is required.

Driver installation

When you switch on the PC for the first time, the optionally pre-installed operating system will be started. For any additional hardware you have connected, you have to install the drivers yourself afterwards. In addition, the Beckhoff Device Manager starts automatically. The Device Manager is a software from Beckhoff that supports you in configuring the PC.

If you have ordered the PC without an operating system, you must install this and the driver software for the additional hardware you have connected and for the devices in the PC yourself. Please follow the instructions in the documentation for the operating system and the additional devices.

UPS software components

The UPS software components with the corresponding drivers must be installed on the PC to operate the power supply unit as a UPS. The software components and drivers are already installed on delivery of the PC with operating system. Otherwise, you have to install the installation package Beckhoff UPS yourself.

You can obtain the installation package from Beckhoff Service (service@beckhoff.com), who will provide you with the package. You then use the installation package to install the UPS software components. The UPS software components come with a detailed help function. Call up the help files either directly from the configuration register by clicking the Help button or start the file under Start > Programs > Beckhoff > UPS software components.

For more detailed information on UPS configuration, refer to chapter 5.2 UPS configuration.
