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�

• Improper or non-intended use may lead to malfunctions of the unit or to un-

wanted effects in your application� That is why installation, electrical connec-

tion, set-up, operation and maintenance of the unit must only be carried out by

qualified personnel authorised by the machine operator�

• In order to guarantee the correct condition of the device for the operating time it

is necessary to use the device only for media to which the wetted materials are

sufficiently resistant (→ Technical data).

• The responsibility whether the measurement devices are 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 units result in a loss of the warranty claims�

• During installation or in case of a fault (housing damage) media under high

pressure or hot media can leak from the system�

►Install the unit according to the applicable rules and regulations�

►Ensure that the system is free of pressure during installation�

►Ensure that no media can leak at the mounting location during installation�

►Equip the unit with suitable protection (e�g� cover) to avoid hazard to person-

nel from leaking media�

3 Functions and features

The unit monitors liquid media (water, glycol solutions, industrial oils, coolants)�

It detects the two process categories volumetric flow or medium temperature�

4 Function

• The unit detects the volumetric flow quantity based on the principle of differen-

tial pressure�

• The unit features an IO-Link interface and is designed for full bidirectional

communication�

• The unit displays the current volumetric flow quantity or temperature� It gener-

ates 2 output signals according to the parameter setting:

OUT1/IO-Link: 4 selection options Parameter setting

- Switching signal: limit values for volumetric flow

quantity

→ 9.2.1; → 9.2.2

- or switching signal: limit values for temperature → 9.3.1; → 9.3.2

OUT2: 2 selection options Parameter setting

- Analogue signal for volumetric flow quantity → 9.2.3

- or analogue signal for temperature → 9.3.3

4.1 Switching function

OUT1 changes its switching status if it is above or below the set switching limits

(flow or temperature)� Hysteresis or window function can be selected� Example of

volumetric flow monitoring:

SP = set point

rP = reset point

HY = hysteresis

Hno / Fno = NO (normally open)

FH = upper limit value

FL = lower limit value

FE = window

Hnc / Fnc = NC (normally closed)

When the hysteresis function is set, the set point (SPx) is defined first and

then the reset point (rPx) which must be of a lower value� If only the set

point is changed, the reset point remains constant�

When set to the window function the set and reset points have a fixed hys-

teresis of 0�25 % of the final value of the measuring range� This keeps the

switching status of the output stable if the volumetric flow varies slightly�

4.2 Analogue function

The unit provides an analogue current signal that is proportional to the volumetric

flow quantity and the medium temperature� Within the measuring range the output

signal is between 4 and 20 mA� Outside the measured and displayed value range

or in case of a fault the signals < 4 mA or > 20 mA are provided (→ Figures).

1: Output current in mA

2: Volumetric ow quantity (nal value of the measuring range MEW = 100 %)

3: Medium temperature

4: Measuring range

5: Display range

6: The unit is in the error state (FOU = OFF)

7: The process value transmitted in an analogue way is therefore above the display range

8: The unit is in the error state (FOU = ON)

4.3 IO-Link

4.3.1 General information

This unit has an IO-Link communication interface which requires an IO-Link-capa-

ble 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�

You will find more detailed information about IO-Link at www�ifm�com/gb/io-link�

4.3.2 Device-specific information

You will find the IODDs necessary for the configuration of the IO-Link unit and

detailed information about process data structure, diagnostic information and

parameter addresses at www�ifm�com/gb/io-link�

4.3.3 Parameter setting tools

You will find all necessary information about the required IO-Link hardware and

software at www�ifm�com/gb/io-link�

5 Installation

IN OUT

►Insert the unit into the pipe

according to the direction of flow

(arrow) and tighten�

With water containing dirt:

►horizontal installation recom-

mended�

IN = inlet

OUT = outlet

Baffled pipes on the sensor's inlet or outlet side are not necessary�

The sensor has the function of a non-return valve�

The sensor head can be rotated by 360°�

►Do not install the unit on ferromagnetic materials�

(Ferromagnetic materials are all metals exerting an attractive force on test

magnets�)

►Do not operate the unit in the vicinity of magnetic constant and alternating

fields (e�g� welding systems)�

►If the sensors are installed side by side, observe a minimum distance of 50 mm

between the sensor axes�

6 Electrical connection

The unit must be connected by a qualified electrician�

The national and international regulations for the installation of electrical

equipment must be adhered to�

Voltage supply according to EN 50178, SELV, PELV�

►Disconnect power�

►Connect the unit as follows:
