3. Make the following settings as necessary:
– Unit for pressure specifications (default is mbar)
– Differential pressure calculation
– Upper and lower pressure limit values
– Activate the pressure diagnosis by selecting whether
failure to reach a limit or exceeding a limit should be
signaled.
– If necessary, make the following further settings:
sensor limit diagnosis, delay for pressure diagnosis,
measured value smoothing and hysteresis.
4. The current pressure values or the differential pressure
values are shown on the LCD display and notified to the
field bus or the network.
If pressure diagnosis is activated, limit value overruns or
underruns (dependent on the parameterisation) are shown
on the LCD display with v or V and notified via the field
bus or the network (see section 7.5.1).
