Avoid static and dynamic overpressure exceeding the specified overload
pressure by taking appropriate measures.
The indicated bursting pressure must not be exceeded.
Even if the bursting pressure is exceeded only for a short time, the unit
may be destroyed. ATTENTION: Risk of injury!
The units are vacuum resistant. With a nominal pressure range ≤
300 mbar observe the specifications in the data sheet!
Pressure Equipment Directive (PED):
The units comply with the Pressure Equipment Directive and are designed
and manufactured for group 2 fluids in accordance with the sound
engineering practice.
Use of group 1 fluids on request!

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.
4.1  Communication, parameter setting, evaluation
OUT1 (pin 4)
OUT2 (pin 2)

• 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.

P = system pressure; HY = hysteresis; FE = window

When set to the window function the set and reset points have a fixed
hysteresis of 0.25 % of the final value of the measuring span.

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.
