4 Function

• ▷ The device displays the current system pressure.
• It generates output signals according to the operating mode and the parameter setting.
  • Moreover, it provides the process data via IO-Link.
• The device is designed for fully bidirectional communication. So the following options are possible:
• Remote display: reading and displaying the current system pressure.
• Remote parameter setting: reading and changing the current parameter setting.
  – IO-Link parameter setting: IO-Link (→ 8)

4.1 IO-Link

IO-Link is a communication system for connecting intelligent sensors and actuators to automation systems. IO-Link is standardised in the IEC 61131-9 standard.

General information on IO-Link at io-link.ifm

Input Output Device Description (IODD) with all parameters, process data and detailed descriptions of the device at documentation.ifm.com

IO-Link offers the following advantages:

• Interference-free transmission of all data and process values
• Parameter setting in the running process or presetting outside the application
- Parameters for identifying the connected devices in the system
• Additional parameters and diagnostic functions
• Automatic backup and restore of parameter sets in case of device replacement (data storage)
- Logging of parameter sets, process values and events
• Device description file (IODD - Input Output Device Description) for easy project planning
• Standardised electrical connection
- Remote maintenance

4.2 Zero point behaviour of the device display and outputs

Due to permissible device tolerances and temperature changes, the sensor can show a deviation from the zero point when no pressure is applied. To prevent this, the device is equipped with functions that keep the measured signal more stable at the process value 0.

Zero point behaviour of the device display and switching output:

Fig. 1: Device display and switching output

1: Process value
2: Sensor output signal with hysteresis (green)
3: Ideal measurement signal (red)
4: System pressure
5: Zero point stabilisation → Data sheet

The first process value that is shown on the device display and can be evaluated via the switching output is determined by the zero point stabilisation.

The switching output cannot be configured within the zero point stabilisation.

The zero point stabilisation is specified in \% of the span → Data sheet.

Zero point behaviour of the analogue output and communication via IO-Link:

Fig. 2: Analogue output and communication via IO-Link

1: Process value
2: Sensor output signal (green)
3: Ideal measurement signal (red)
4: System pressure
5: Zero point stabilisation → Data sheet
6: 0.5 x zero point stabilisation → data sheet

The first process value that can be evaluated via the analogue output and the IO-Link communication is indicated by the half zero point stabilisation (6).

In the further range of the zero point stabilisation (5), the output signal of the sensor runs at a larger gradient angle.

The zero point stabilisation is specified in \% of the span → Data sheet.

4.3 Operating modes

The operating mode is defined by the wiring ( → 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 or 20...4 mA

4.3.2 3-wire operation

OUT1 (pin 4)	2 possibilities (automatic changeover)• switching signal for pressure limit• Communication via IO-Link
OUT2 (pin 2)	3 possibilities (manual changeover in the menu)• switching signal for pressure limit• Analogue signal proportional to pressure 4...20 mA• Analogue signal proportional to pressure 20...4 mA

4.4 Switching function (only for 3-wire operation)

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: [OUx] = [Hno] (→ Figure hysteresis function).
• Hysteresis function / normally closed: [OUx] = [Hnc] (→ Figure hysteresis function).

First the set point (SPx) is set, then the reset point (rPx) with the requested difference.

• Window function / normally open: [OUx] = [Fno] (→ Figure window function).
• Window function / normally closed: [OUx] = Fnc
• The width of the window can be set by means of the difference between SPx and rPx. SPx = upper value, rPx = lower value.

Fig. 3: Hysteresis function

Fig. 4: Window function

P =	System pressure
HY =	Hysteresis
FE =	Window

4.5 Analogue function

The analogue output can be configured.

- [OU2] defines whether the set measuring range is provided as 4...20 mA ([OU2] = [I]) or 20...4 mA ([OU2] = [InEG]).

Scaling can be set by means of the teach process or by entering a value for the parameters ASP and AEP.

• Teaching the analogue start point [tASP] or setting the parameter [ASP] defines at which measured value the output signal is 4 mA (20 mA at [InEG]).
• Teaching the analogue end point [tAEP] or setting the parameter [AEP] defines at which measured value the output signal is 20 mA (4 mA at [InEG]).

Minimum difference between [ASP] and [AEP] = 25 % of the final value of the measuring range (Turn-Down 1:4); for PI2x09: 25 % of the measuring span.

P:	System pressure
MAW:	Initial value of the measuring range
MEW:	Final value of the measuring range
1:	[OU2] = [I]
2:	[OU2] = [InEG]

In the set measuring range the output signal is between 4 and 20 mA ([OU2] = [I]) or between 20 and 4 mA ([OU2] = [InEG]).

It is also indicated:

• System pressure above the measuring range:

• Output signal > 20 mA at [OU2] = [I].
• Output signal 4 to 3.8mA at [OU2] = [InEG].

• System pressure below the measuring range:

• Output signal 4 to 3.8 mA at [OU2] = [I].
• Output signal > 20 mA at [OU2] = [InEG].

4.6 Customer-specific calibration

The customer-specific calibration changes the curve of measured values compared to the real measured values Calibrate curve of measured values ( → ☐ 30).

• Two calibration points can be defined (CP1, CP2). The two points are independent of each other.
• The two calibration points must be within the scaled measuring range. Analogue function (→ 10)
• The zero point calibration [COF] influences the calibration of the curve of measured values. Recommendation: Set [COF] to 0, then calibrate the curve of measured values Zero-point calibration ( → ☐ 29).

After a change the calibration can be reset to factory setting: [res]

5 Installation

CAUTION

If the medium temperature is above 50\ °C ( 122\ °F ), parts of the housing can increase in temperature to over 65\ °C ( 149\ °F ).

▷ Risk of burns.

▶ Protect the housing against contact with flammable substances and unintentional contact.

CAUTION

▷ Before installing and removing the device

▶ Make sure that no pressure is applied to the system and there is no medium in the pipe or tank. Also always take into account the potential dangers related to extreme machine and medium temperatures.

CAUTION

▷ Before installing and removing the device

▶ Allow the device and process adapter to cool down before maintenance.

Available accessories: www.ifm.com.

When using siphons

▶ Fill these with liquid before set-up.

5.1 Connection versions clamp seals

The clamp adapter must be suitable for the system pressure.

▶ Use connection pieces with a suitable system seal, clamp and screw plug.

▶ For installation where EHEDG conditions have to be met: → EHEDG position paper

The tightening torque of the clamp adapter depends on the sealing version and the Shore hardness of the seal used.

▶ Tightening torque for the clamp adapter: → Manufacturer's specification

Clamp connection to pipe according to DIN 11866	PI22xxEffective diameter:Dw = 34 mm	PI23xxEffective diameter:Dw = 47.5 mm
Series A - metric	Nominal width DN 40Di = 38 mm	Nominal width DN 50Di = 50 mm
Series B - ISO	Nominal widthDN / OD 42.4Di = 38.4 mm	----
Series C - ASME	Nominal widthDN / OD 1 1⁄2“Di = 34.8 mm	Nominal widthDN / OD 2“Di = 47.5 mm

Internal pipe diameter Di (d2) > diameter of the effective area of the diaphragm Dw (d1).

5.2 Use in hygienic areas according to 3-A

The following applies to devices with 3-A certification:

▶ Only use adapters with 3-A certification for the process connection.
▶ Do not install the device in the lower section of the pipe or tank (positions 4 and 5) in order that the medium can run off the area of the measuring element.

5.3 Use in hygienic areas to EHEDG

The device is suited for CIP (cleaning in process) when installed correctly.

▶ Observe the application limits (temperature and material resistance) according to the data sheet.

▶ Ensure that the installation of the device in the system complies with EHEDG guidelines.
▶ Use self-draining installation.
▶ Only use process adapters permitted according to EHEDG with special seals required by the EHEDG position paper.

The seal of the system interface must not be in contact with the effective area of the ceramic cell. Any influence of the seal on the effective area must be avoided.

▶ When mounted in a tank, the installation must be flush mount. If not possible then direct water jet cleaning must be possible. Dead spaces must be detected.

▶ To avoid dead space adhere to the dimensions: L < D

5.4 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 filter cover with circumferential ports.

For a correct functioning of the ventilation 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 ventilation diaphragm with liquids to avoid negative pressure in the measuring system (resulting in a slightly falsified measured value) and additional strain on the diaphragm.

5.5 Orientation filter cover

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 horizontally and the display is orientated upwards or downwards, the condensate is less likely to escape via the filter cover, as this is located at the top or bottom point ( → Figure Filter cover).

Fig. 5: Filter cover

▶ Ideal orientation (1): The filter cover is in a horizontal position.
The ventilation diaphragm (2) in the filter cover is in a vertical position.
▶ Maximum inclination of the filter cover: 30° (3)

5.6 Filter cover

Replace filter cover:

(1) Replacement of the filter cover incl. ventilation diaphragm (E30142).

(2) Replacement of the filter cover with a closed version (E30148)*.

When using the closed filter cover, there is no more pressure compensation of the measuring cell. This results in measurement deviations caused by:

• Fluctuations of the atmospheric pressure.
• Pressure fluctuations inside the device in case of temperature changes ( Δ 10 K ≤ 30 mbar ).

Improve the protection of the filter cover:

(3) Replacement of the filter cover with a version with a tube fitting and a vent tube that ends in a protected and dry area (E30139).

(4) Set of accessories (E30467) with integrated replacement diaphragm (GORE), for high degree of soiling and / or high climate pollution. Function: (→ Instructions E30467)

▶ Avoid soiling and moisture during the replacement.
▶ Clean the thread carefully and without residues.
▶ Do not damage the adhesive surface for the diaphragm on the sensor.
▶ Observe the orientation of the filter cover ( → Installation instructions E30139 / E30467).
