4.3 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)
u
Read parameters via IO-Link or contact the manufacturer.
4.4 Operating modes
The operating mode is defined by the wiring (
Ò
Electrical connection) and automatically recognised by
the unit.
4.4.1 2-wire operation
OUT2 (pin 2)
Analogue signal proportional to pressure 4...20 mA
4.4.2 3-wire operation
OUT1 (pin 4)
Communication via IO-Link
OUT2 (pin 2)
Analogue signal proportional to pressure 4...20 mA
4.5 Analogue output
The device provides an analogue signal proportional to the pressure. Within the measuring range the
analogue signal is between 4...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 the following figure is provided.
