4 Commissioning
The commissioning process enables you to parametrise the transmitter with only a few actions. The empty and full adjustment enable
setting the thresholds of 4 und 20mA . The wavelet set lies between these two thresholds. This is represented by the transmitter by a
16mA loop current linear to the process.
When making the adjustment, ensure that the (under) pressure lies within the max. permissible threshold for the
transmitter.
4.1 Setting the measuring range begin (empty adjustment)
Use the empty adjustment to set the start of the transmitter measuring range. To this end, apply the desired (under) pressure to the
transmitter / filling level and hold the
key depressed. Whilst continuing to hold the key depressed, the status LED will extinguish and
then after c. 5 s will illuminate green permanently. You can release the key - the transmitter has saved the pressure value as the new
measuring range begin and issues a 4mA signal.

4.2 Setting the end of the measuring range (full adjustment)
Use the full adjustment to set the transmitter measuring range end. To this end, apply the desired (under) pressure to the transmitter /
filling level and hold the
key depressed. Whilst continuing to hold the key depressed, the status LED will illuminate and then after c. 5 s
will continue to illuminate green. You can release the key - the transmitter has saved the pressure value as the new measuring range end
and issues a 20mA signal.

If the status LED illuminates red after extinguishing, the transmitter is not able to process the current (under)
pressure for the empty or full adjustment. In this case, check whether the measuring range is smaller than 25% of
the nominal measuring range. Before adjusting, it may be necessary to restore the factory settings, so that
threshold values already set can be reset to their origin.
