10.11 Others

10.11.1 Use of USB port
The USB port is intended for temporary use to make the parameter settings, the
configuration and for work in connection with commissioning.
When using the USB port, the controller can be securely operated, tested and set with
no need for using the mains cable.
10.11.2 Powering the controller via the USB port
via the port
If the controller shall be powered via the USB port, a HUB with power supply is
required, capable of delivering at least 500 mA at every outlet.
When supplying power via the USB port, relays and analog output are deenergized to
reduce power consumption.
Note!
Check to ensure that power supply to the measuring converter (G+ and G-) is not
connected. This increases power usage via the USB port as well.
The measuring accuracy specified in chapter 12 Technical data does not apply when
powering the controller via the USB port.
