8.3.1 Digital interface settings

Changing the operating pressure:
▶ Make sure that all system components can work with the required operating
pressure.
▶ Make sure that the pressure limitation settings for the intended operating
pressure are correct (10 % over max. operating pressure).
▶ The pressure command value can also be changed during running operation.
Command values entered in the software become immediately effective in the
process!
Pressure command value change (applies for "Basic" and "Advanced" configurations):
1. Make sure that parameter F1.03 is set to 0.
2. Set the required operating pressure in parameter F1.05.
Change of up to four pressure ratings (applies for "Basic" and "Advanced"
configurations):
1. Make sure that parameter F1.03 is set to 1 (parameter F1.04 indicates the status
of the pre-selected pressure).
2. Set the required operating pressure for stage 1 in parameter F1.05.
3. Set the required operating pressure for stage 2 in parameter F1.06.
4.
Set the required operating pressure for stage 3 in parameter F1.07.
5. Set the required operating pressure for stage 4 in parameter F1.08.
6. Set the function of the digital inputs 15X1 at pin 7 and pin 8:
– Parameter F2.19 = 1 (pressure command value selection bit 0)
– Parameter F2.20 = 2 (pressure command value selection bit 1)
In "Premium" configuration, the pressure command value is defined via the
multi-Ethernet interface.
