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.
Correct condition of the device for the operating time can only be guaranteed if the device is
only used for media to which the wetted materials are sufficiently resistant → 3.1 Applications.
If the devices are used in gas applications with pressures > 25 bar the notes in chapter 3.1 for
devices with the marking *), must be absolutely observed.
The responsibility whether the measurement device is suitable for the respective application
lies with the operator. The manufacturer assumes no liability for consequences of misuse
by the operator. Improper installation and use of the devices result in a loss of the warranty
claims.

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:
oRemote display: reading and display of the current system pressure.
oRemote parameter setting: reading and changing the current parameter setting.
4.1 Communication, parameter setting, evaluation
OUT1 (Pin 4)
Switching signal for system pressure limit value
Communication via IO-Link
OUT2 (Pin 2) Analog signal 4 ... 20mA / 0 ... 10V
4.2 Switching function
OUTx 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). The hysteresis defined remains even if
SPx is changed again.
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.

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])
34D-xxxxx-DA1-AA:
Analogue signal 4...20 mA / 0...10 V corresponds to the measuring range 0...10 bar. Negative
pressure values cannot be represented via the analogue output for the indicated units.
Current signal 4 ... 20 mA
Voltage signal 0 ... 10V
P = system pressure;
MEW = final value of the measuring range
In the measuring range of the respective unit the
output signal is between 4 and 20 mA.
In the measuring range of the respective unit
the output signal is between 0 and 10 V.
It is also indicated:
System pressure above the measuring range:
20...20.5 mA.
- Fault indication from 21.5 mA.
System pressure below the measuring range:
4...3.8 mA.
It is also indicated:
System pressure above the measuring
range: 10...10.3 V
- Fault indication from 11 V.
