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 unwan-

ted effects in your application� That is why installation, electrical connection,

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

qualified personnel authorised by the machine operator�

• Check the compatibility of the product materials (→ Technical data) with the

media to be measured in all applications�

• The responsibility whether the measurement devices are suitable for the res-

pective 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�

3 Functions and features

The unit monitors the system temperature in machinery and plants�

4 Function

• The unit displays the current system temperature�

• It features an IO-Link interface and is designed for full bidirectional communi-

cation�

• The unit generates 2 output signals according to the parameter setting:

OUT1/IO-Link:

- Switching signal, limit values for temperature

OUT2: 2 selection options

- Switching signal, limit values for temperature

- Analogue signal for temperature

4.1 Switching function

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

Hysteresis or window function can be selected�

Hysteresis function Window function

SPx

rPx

FHx

FLx

T = Temperature

SPx = set point

rPx = reset point

HY = hysteresis

Hno = hysteresis NO (normally open)

Hnc = hysteresis NC (normally closed)

T = Temperature

FHx = upper limit value

FLx = lower limit value

FE = window

Fno = window NO (normally open)

Fnc = window 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 upper limit value (FHx) and the lower

limit value (FLx) have a fixed hysteresis of 0�25 % of the final value of the

measuring range� This keeps the switching state of the output stable if the

temperature varies slightly�

4.2 Analogue function

• The unit converts the measured signal into a temperature-proportional ana-

logue signal� Depending on the parameter setting the output signal is at:

4��20 mA [ou2] = I

20��4 mA [ou2] = Ineg

0��10 V [ou2] = U

10��0 V [ou2] = Uneg

• The analogue signal can be scaled, that means the limits of the measuring

range for the lower output signal (ASP2 = analogue start point) and the upper

output signal (AEP2 = analogue end point) can be set�

Minimum distance between [ASP2] and [AEP2] = 5 K�

MAW = initial value of the measuring range

MEW = final value of the measuring range

ASP2 = analogue start point

AEP2 = analogue end point

Within the measuring range the output signal is between 4 and 20 mA�

If the temperature value (T) is outside the measuring range, the following output

signal is displayed:

[ou2] = I [ou2] = Ineg

T < MAW (ASP2) 3�8��4 mA 20�5��20 mA

T > MEW (AEP2) 20��20�5 mA 4��3�8 mA

In case of internal fault, the output signal behaves according to the parameter set

in [FOU2]:

[FOU2] = On [FOU2] = OFF

[ou2] = I 21 mA 3�5 mA

[ou2] = Ineg 3�5 mA 21 mA

Within the measuring range the output signal is between 0 and 10 V�

If the temperature value (T) is outside the measuring range, the following output

signal is displayed:

[ou2] = U [ou2] = Uneg

T < MAW (ASP2) 0 V 10�3��10 V

T > MEW (AEP2) 10��10�3 V 0 V

In case of internal fault, the output signal behaves according to the parameter set

in [FOU2]:

[FOU2] = On [FOU2] = OFF

[ou2] = U 10�6 V 0 V

[ou2] = Uneg 0 V 10�6 V

4.3 Display colour change

The colour of the characters in the display can be set via the parameter [colr]�

With the parameters rED (red) and GrEn (green), the display is permanently set to

one colour� Via further parameters, the colour of the characters changes according

to the measured value:

OUT1 OUT2 OUT1 and OUT2 Colour change to��

Parameter r1ou r2ou r-cF red

G1ou G2ou G-cF green

4.4 IO-Link

4.4.1 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�

software at www�ifm�com/gb/io-link�

5 Installation

Before installing and removing the unit: Ensure that no medium can leak at

the process connection�

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�
