Important note
Non-compliance can result in malfunction or interference.
2. Safety instructions
Please read this document prior to set-up of the unit. Ensure that the product is suitable for your
application without any restrictions.
If the operating instructions or the technical data are not adhered to, personal injury and/or
damage to property can occur.
Check the compatibility of the product materials with the media to be measured in all
applications.).
3. Functions and features
The unit monitors the system pressure/differential pressure in compressed air networks and
pneumatic systems of machines and plants.
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!
Pressure Equipment Directive (PED): The units comply with section 3, article (3) of the
Directive 97/23/EC and are designed and manufactured for media of fluid group 2 (stable
gases and non-superheated liquids) in accordance with the sound engineering practice.

4. Function
4.1 Processing of the measured signals
The unit displays the current system pressure.
It generates 2 output signals according to the parameter setting.
OUT1 Switching signal for limit value
OUT2 2 options
• Switching signal for system pressure limit value.
• Diagnostic signal (output 1 is inactive in case of a fault).
4.2 Switching function
OUT1 changes its switching state if it is above or below the set switching limits (SP1, rP1). The
following switching functions can be selected:
Hysteresis function / normally open: [ou1] = [Hno] (→ fig. 1)
Hysteresis function / normally closed: [ou1] = [Hnc] (→ fig. 1)
First the set point (SP1) is set, then the reset point (rP1) with the requested difference.
Window function / normally open: [ou1] = [Fno] (→ fig. 2).
Window function / normally closed: [ou1] = [Fnc] (→ fig. 2).
The width of the window can be set by means of the difference between FH1 and FL1. FH1 =
upper value, FL1 = lower value.
P = system pressure / differential pressure; HY = hysteresis; FE = window

4.3 Diagnostic function
Output 2 is used as diagnostic output based on the DESINA specification if [ou2] = [diA].
If there is no fault, the output is switched and carries Ub+ .
In case of malfunctions in the following areas, the output is inactive:
oshort circuit in output 1.
oEPROM function.
oRAM function.
oparameter setting.
oprocessor function.
5. Installation
Before installing and removing the unit: Make sure that no
pressure is applied to the system.
►Screw the pressure connection or adapter G1/8 to the main
pressure connection (1) and tighten:
Maximum tightening torque: 8 Nm.
Maximum thread length: 7.5mm
►If required: Screw the pressure connection or adapter M5 to the
auxiliary pressure connection (2) and slightly tighten to avoid
damage to the thread:
Maximum tightening torque: 2.5 Nm.
Maximum thread length: 7.5mm
