If there is no supply voltage of 24 V, the operator display immediately
darkens. The user cannot execute any actions via the operator display
during the shutdown of the control cabinet PC.
3. DIS function

7.1.4 XUSB Interfaces
The devices feature four USB interfaces on the connector panel (XUSB1/2
and XUSB3/4), and, depending on the version, one interface on the front
panel.
USB devices (e.g. keyboard) switch off if the power consumption
of all USB connectors exceeds 1 A.
The maximum power consumption of one USB connector must
not exceed 500 mA. The total current of all USB connectors must
not exceed 1 A. The voltage supply of other VDP function units
are not impaired by the switched-off USB voltage.
●
The USB devices are enabled as soon as the total current is
below 1 A (time delay approx. 30 seconds) or as soon as the
power consumption of one connector is below 500 mA.
● In the taskbar no message is displayed that the USB devices
are disabled.

CDI: Operating the USB connections on the VDP 16.3/40.3 in USB2.0 mode
The USB connections on the VDP 16.3/40.3/60.3 only support USB1.1
because the data is transferred to the control cabinet PC by using the XSER
interface. If USB2.0 is required on the VDP 16.3/40.3/60.3, it can be
implemented by connecting the XUSBIN connection to the
38/57
