4 Function
• The unit displays the current system pressure.
• It generates output signals according to the operating mode and the parameter
setting.
• It moreover provides the process data via IO-Link.
• The unit is laid out for fully bidirectional communication. So, the following
options are possible:
-- Remote display: reading and display of the current system pressure.
-- Remote parameter setting: reading and changing the current parameter
setting.
-- IO-Link parameter setting → 4.4.

•Switching signal for system pressure limit value
•Communication via IO-Link
•Switching signal for system pressure limit value
•Analogue signal 4...20 mA / 0...10 V
4.2 Switching function
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: [ou1/ou2] = [Hno] (→ fig. 1).
• Hysteresis function / normally closed: [ou1/ou2] = [Hnc] (→ fig. 1).
First the set point (SPx) is set, then the reset point (rPx).
The hysteresis defined remains even if SPx is changed again.
• Window function / normally open: [ou1/ou2] = [Fno] (→ fig. 2).
• Window function / normally closed: [ou1/ou2] = [Fnc] (→ fig. 2).
The width of the window can be set by means of the difference between FHx
and FLx. FHx = upper value, FLx = lower value.

4.3 Analogue function
OUT2 is an analogue output:
• [ou2] defines whether the set measuring range is provided as
4...20 mA ([ou2]= [I]) or as 0...10 V ([ou2] = [U]).
• Analogue start point [ASP2] determines at which measured value the output
signal is 4 mA or 0 V.
• Analogue end point [AEP2] determines at which measured value the output
signal is 20 mA or 10 V.
Minimum distance between [ASP2] and [AEP2] = 20 % of the measuring span.
