4.6.2 3-wire operation
OUT1 (pin 4) 2 possibilities (automatic changeover)
• switching signal for pressure limit
• Communication via IO-Link
OUT2 (pin 2) 3 possibilities (manual changeover in the menu)
• switching signal for pressure limit
• Analogue signal proportional to pressure 4...20 mA
• Analogue signal proportional to pressure 20...4 mA
4.7 Switching function (only for 3-wire operation)
OUTx changes its switching status if it is above or below the set switching limits (SPx, rPx). The
following switching functions can be selected:
• Hysteresis function / normally open: [OUx] = [Hno] (Ò Figure hysteresis function).
• Hysteresis function / normally closed: [OUx] = [Hnc] (Ò Figure hysteresis function).
First the set point (SPx) is set, then the reset point (rPx) with the requested difference.
• Window function / normally open: [OUx] = [Fno] (Ò Figure window function).
• Window function / normally closed: [OUx] = [Fnc](Ò Figure window function)
• The width of the window can be set by means of the difference between SPx and rPx. SPx = upper
value, rPx = lower value.

4.8 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. The analogue signal in case of an error is
adjustable:
