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.
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.
Checkthecompatibilityoftheproductmaterials(→12Technicaldata)withthe•
media to be measured in all applications.

3 Functions and features
The unit monitors the system temperature in machinery and plant.
4 Function
4.1 Communication, parameter setting and evaluation
The unit displays the current system temperature.•
It generates 2 output signals according to the parameter setting.•
OUT1 Switching signal for system temperature limit value.
OUT2 Analogue signal for system temperature.
It moreover provides the process data via IO-Link.•
The unit is laid out for fully bidirectional communication. So, the following op-•
tions are possible:
Remote display: Reading and displaying the current system temperature.-
Remote parameter setting: Reading and changing current parameter settings-
with the FDT service program ifm Container or via IO-Link.
Using the FDT service program ifm Container, the current parameter settings-
can be stored and transferred to other units of the same type.
The program library of the available DTM objects can be found at www.ifm.com

4.2 Switching function
OUT1 changes its switching state if it is above or below the set switching limits
(SP1, rP1). The following switching functions can be selected:
Hysteresisfunction/normallyopen:[OU1]=[Hno](→fig.1).•
Hysteresisfunction/normallyclosed:[OU1]=[Hnc](→fig.1).•
First the set point (SP1) is set, then the reset point (rP1) with the requested differ-
ence.
Windowfunction/normallyopen:[OU1]=[Fno](→fig.2).•
Windowfunction/normallyclosed:[OU1]=[Fnc](→fig.2).•
The width of the window can be set by means of the difference between SP1 and
rP1. SP1 = upper value, rP1 = lower value.

T = system temperature; HY = hysteresis; FE = window
4.3 Analogue function
[OU2] defines if the set measuring range is provided as a 4...20 mA signal•
([OU2] = [ I]) or a 0...10 V signal ([OU2] = [U]).
Analogue start point [ASP] defines at which measured value the output signal•
is 4 mA / 0 V.
Analogue end point [ AEP] defines at which measured value the output signal•
is 20 mA / 10 V.
Minimum distance between [ASP] and [AEP] = 5 K.

Current output 4...20 mA
Factory setting Measuring range scaled
In the set measuring range the output signal is between 4 and 20 mA.
The green LED also indicates:
Temperature above the measuring range: Output signal 20...20.5 mA.•
Temperature below the measuring range: Output signal drops to max. 3.8 mA.•
If the detection zone is not reached or is exceeded (T < -60°C or T > +160°C), the output•
behavesaccordingtotheparametersetinFOU2(→9.5.3).
Voltage output 0...10 V
Factory setting measuring range scaled
In the set measuring range the output signal is between 0 and 10V.
The green LED also indicates:
Temperature above the measuring range: Output signal 10...10.3 V.•
If the detection zone is not reached or is exceeded (T < -60°C or T > +160°C), the output•
behavesaccordingtotheparametersetinFOU2(→9.5.4).

5 Installation
Using process adapters the unit can be adapted to different process connections.
Adapters have to be ordered separately as accessories.
Immersion depth of the sensor: min. 12 mm in the pipe. If you use the adapter
supplied as accessory the correct immersion depth is ensured.
Mounting dimensions with
M12 adapter
Mounting dimensions with
G¼ adapter
Mounting dimensions with
G½ adapter
For optimum response times:
Orientation of the unit: Connector►
against the flow direction of the
medium.
Before installing and removing the unit: Ensure that no medium can leak at
the process connection.
�
Grease the threads of the process connection (1), adapter (2) and nut (3).►
Note: The sensor tip (A) must not be in contact with grease.
Screw the suitable adapter into the process connection.►
Place the temperature sensor onto the adapter and tighten the nut. Tightening►
torque max. 50 Nm. Ensure that the unit is correctly oriented.
