4.1 IO-Link
4.1.1 General information
This unit has an IO-Link communication interface which requires an IO-Link
capable module (IO-Link master) for operation�
The IO-Link interface enables direct access to the process and diagnostic data
and provides the possibility to set the parameters of the unit during operation�
In addition, communication is possible via a point-to-point connection with a USB
adapter cable�
The IODDs necessary for the configuration of the unit, detailed information about
process data structure, diagnostic information, parameter addresses and the
necessary information about the required IO-Link hardware and software can be
found at www�ifm�com�
4.1.2 Functions only available via IO-Link communication
• Device temperature: The internal temperature of the sensor can be read via the
A-cyclic IO-Link channel�
• Application-specific tag: freely definable text assigned to the unit�
• Function tag: freely definable text describing the device function in the plant�
• Location tag: freely definable text describing the installation location in the
plant�
For more detailed information refer to the device-specific IO Device Description
PDF at www�ifm�com�
4.1.3 Set-up via IO-Link
The device parameters can be set via IO-Link:

In case of a fault indication (= 21�5 mA):
►Read parameters via IO-Link or contact the manufacturer
4.3 Operating modes
The operating mode is defined by the wiring (→ 6 Electrical connection) and
automatically recognised by the unit�
4.3.1 2-wire operation
OUT2 (pin 2) Analogue signal proportional to pressure 4���20 mA
4.3.2 3-wire operation
OUT1 (pin 4) Communication via IO-Link
OUT2 (pin 2) Analogue signal proportional to pressure 4���20 mA
4.4 Analogue output
The device provides an analogue signal proportional to the pressure�
Within the measuring range the analogue signal is between 4 and 20 mA�
The measuring range is scalable:
• [ASP2] defines at which measured value the output signal is 4 mA�
• [AEP2] defines at which measured value the output signal is 20 mA�
Minimum distance between [ASP2] and [AEP2] = 20 % of the final value of
the measuring range�
If the measured value is outside the measuring range or in the event of an internal
error, the current signal indicated in figure 1 is provided�

5.5 Protective cover
5.5.1 Function ventilation diaphragm
The ventilation diaphragm enables the relative pressure measurement since
barometric and temperature-dependent pressure fluctuations between the
measuring cell and the environment are compensated for�
The ventilation diaphragm is protected against damage by a screwed cap with
circumferential ports�
For a correct functioning of the diaphragm please take the following into
account:
►Remove soiling and cleaning agents immediately using plenty of lime-
deficient splash water�
If the sensor is in a cooling stage:
►Avoid contact of the diaphragm with liquids:
> Avoids negative pressure in the measuring system resulting in a slightly
falsified measured value and additional strain on the diaphragm�
5.5.2 Orientation of the filter cover
The filter cover is freely rotatable around the sensor's axis and thus adaptable to
the environmental conditions�
When the sensor is mounted in a vertical position, the condensate escapes
through the ports in the protective cap due to gravity�
When the sensor is mounted in a horizontal position or similar, the filter protection
cap must be rotated towards one of the two lateral faces to bring the GORE
diaphragm into a vertical position� This guarantees the optimum drainage for
liquids�

16
To ensure an optimum function of the pressure compensation element,
align the filter cover as shown in Fig� 1�

5.6 Filter cover
Replace filter cover:
1Exchange the filter cover incl� GORE diaphragm (E30142)�
2Replace the filter cover with a closed version (E30148) (*)
Improve the protection of the filter cover:
3Replace the filter cover with a version with a tube fitting and a vent tube that ends in a
protected and dry area (E30139)�
4Set of accessories (E30467) with integrated replacement diaphragm (GORE) for high
degree of soiling and / or high climate pollution�
Function: (→ Installation instructions E30467)
►Avoid soiling and moisture during the exchange
►Clean the thread carefully and without residues
►Do not damage the adhesive area of the sensor
►Observe the orientation of the filter cover
(→ Installation instructions E30139 / 30467)

(*)When using the closed cover cap, there is no pressure compensation
of the measuring cell any more� This results in measurement deviations
caused by:
• fluctuations of the atmospheric pressure
• pressure fluctuations inside the unit in case of temperature changes
(Δ 10 K ≤ 30 mbar).

7 Parameter setting
The unit can be configured via the IO-Link function�
►Prepare IO-Link hardware and software for parameter setting�
►Connect the unit with e�g� an IO-Link interface (→ 7.1) or a programmed
memory plug (→ 7.2)�
►Set the parameters�
►Put the unit into operation�
The parameters can be set before installation or during operation�
Changing parameters during operation can influence the function of the
plant�
►Ensure that there will be no malfunctions in your plant�
7.1 Parameter setting via PC
For parameter setting, an IO-Link-capable software is necessary
(e�g� LR DEVICE)�
IO-Link interfaces from ifm are available for the connection of the unit via the USB
interface of a computer → www.ifm.com.
►Prepare computer, software and interface�
►Connect the unit with the IO-Link interface�
►Follow the menu of the IO-Link software�
►Set the parameters�
►Put the unit into operation�
Adjustable parameters (→ 7.4.4)�
7.2 Parameter setting via the memory plug
A parameter set can be written to the unit / can be recorded by the unit via a
memory plug (ifm storage module) → www.ifm.com.
In order to allow for data to be written from the memory plug to the sensor,
the sensor must have the factory setting�

20
If the sensor has been configured, the memory plug records the parameter
set which can then be transferred to other sensors of the same type�
►Load a suitable parameter set (e�g� from a PC or from a sensor of the same
type) to the memory plug�
►Connect the memory plug between sensor and socket�
> Sensor with factory setting:
When voltage is supplied, the parameter set is transferred from the memory
plug to the sensor�
> Sensor with changed settings:
When voltage is supplied, the memory plug records the sensor's parameter set�
►Remove the memory plug�
►Put the unit into operation�
Adjustable parameters (→ 7.4.4)�
You can find more information about the memory plug in the corresponding
technical documentation → www.ifm.com.
7.3 Teach offset with the teach button
An external teach button (E30425) allows for a zero-point calibration (calibration
offset)� The current measured value is taken as internal zero point if this measured
value lies within a range of +/- 3% of the measuring span�
For connection information see the data sheet of E30425
If a teach button is connected, no IO-Link communication is possible
►Integrate the teach button between the installed sensor and the supply cable�
►Maintain the plant pressure constantly at zero (configurable range = +/- 3% of
the measuring span)�
►Press the button for > 2 ��� < 10 s�
> When voltage is supplied, the LED in the button flashes at 2 Hz and configures
the zero point (calibration offset)�
> In case of a fault, the LED flashes at 8 Hz�
