Supply voltage/power supply
The equipment is delivered with the programming adapter set to a power supply
from the PC. However, it is also possible to wire the programming adapter into
the system and program the sensor afterward. To do this, the parameter for the
power supply must be changed to “External supply”. Proceed as follows:
1. Select the “Power supply MPI-200” parameter
2. Press the button
and change the power supply parameter from
“PC M12 not connected”
to
“External, M12 connected”
using the arrow button
3. Press the button
to save the change. The mask is refreshed

Advice
If the sensor is supplied from the control center/PLC, ensure that the power supply is set to “external, M12 connected”.
A supply from the PC would otherwise be superimposed on the 4...20 mA output signal and lead to an incorrect measur-
ing signal.

Connecting the sensor
1. Connect the sensor to the PC via the USB port.
2. The graphic user interface now refreshes and shows the sensor (e.g. level switch
NSL-M).

Advice
If the sensor is not displayed, check the power supply selection and change it
if necessary.
