1 Safety instructions
Please read the product description prior to installing 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 may occur.
Please check for all applications that the product materials (see Technical•
data) are compatible with the media to be measured.
For gaseous media the application is limited to max. 25 bar / 2,5 MPa.•
For the scope of validity cULus: The device shall be supplied from an isolating
transformer having a secondary Listed fuse rated as noted in the following table�

2 Function and features
The pressure sensor detects the system pressure�•
It shows the current system pressure on its display�•
It generates 2 output signals according to the set output configuration�•
OUT1: switching signal for system pressure�-
OUT2: switching signal for system pressure or diagnostic signal�-
Applications
Type of pressure: relative pressure
Order no. Measuring range Permissible

The indicated bursting pressure must not be exceeded� Even if the bursting
pressure is exceeded only for a short time, the unit can be destroyed�
NOTE:Riskofinjury!
For gaseous media the application is limited to max� 25 bar / 2,5 MPa�
3 Function
3.1 Switching function
OUTx changes its switching state when the set switching limits have not been
reached or have been exceeded (SPx, rPx)� The following switching functions can
be selected:
hysteresisfunction/normallyopen:[OUx]=[Hno](→fig.1).•
hysteresisfunction/normallyclosed:[OUx]=[Hnc](→fig.1).•
First the set point (SPx) is set, then the reset point (rPx) with the requested differ-
ence�
windowfunction/normallyopen:[OUx]=[Fno](→fig.2).•
windowfunction/normallyclosed:[OUx]=[Fnc](→fig.2).•
The width of the window can be set by means of the difference between SPx and
rPx� SPx = upper value, rPx = lower value�

8 Parameter setting
During the parameter setting process the unit remains in the operating mode� It
continues its monitoring function with the existing parameters until parameter set-
ting has been terminated�
8.1 Parameter setting general
Each parameter setting requires 3 steps:
1Selecting parameter
Press [Mode/Enter] until the re-►
quested parameter is displayed�
2Setting the parameter value
Press[Set]andkeepthebuton►
pressed�
Currentsettingvalueoftheparam->
eter bit flashes for 5 s�
After 5 s: Setting value is changed:>
incremental by pressing briefly or
scrolling by holding pressed�
The numerical values are incremented continuously� If the value is to be reduced: Let
the display move to the maximum setting value� Then the cycle starts again at the
minimum setting value�
3Acknowledge parameter value
Press [Mode/Enter] briefly�►
The parameter is displayed again�>
The new setting value is stored�
Set more parameters:
Start again with step 1�►
Finishing parameter setting:
Press [Mode/Enter] several times until the current measured value is displayed►
or wait for 15 s� The unit returns to the operating mode if no button is pressed for
over15safteracknowledgementofthenewparametervalue.
