4.2 Defined state in case of a fault
• If a fault is detected, the analogue output passes into a defined state (=
21�5 mA)�
In case of a fault indication
(= 21�5 mA):
►
Read parameters via IO-Link or contact the manufacturer
4.3 Operating modes
The operating mode is defined by the wiring (
Electrical connection) and
automatically recognised by the unit�
4.3.1 2-wire operation
OUT2 (pin 2)
Analogue signal proportional to pressure 4���20 mA
4.3.2 3-wire operation
OUT1 (pin 4)
Communication via IO-Link
OUT2 (pin 2)
Analogue signal proportional to pressure 4���20 mA
4.4 Analogue output
The device provides an analogue signal proportional to the pressure�
Within the measuring range the analogue signal is between 4 and 20 mA�
The measuring range is scalable:
• [ASP2] defines at which measured value the output signal is 4 mA�
• [AEP2] defines at which measured value the output signal is 20 mA�
Minimum distance between [ASP2] and [AEP2] = 20 % of the final value of
the measuring range�
If the measured value is outside the measuring range or in the event of an internal
error, the current signal indicated in figure 1 is provided�
