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.
Check the compatibility of the product materials (→12 Technical data) with the•
media to be measured in all applications.

3 Functions and features
With temperature sensors connected the unit monitors the system temperature in
machinery and plant.
Connectable temperature sensors:
Temperature sensors TS or TT.•
Resistance thermometer RTD (Pt 100 or Pt 1000).•
The unit automatically detects the connected sensor type and configures itself ac-
cordingly The electrical measuring method (3-wire or 4-wire sensor) is determined
viathemenusetting(→9.5.1).
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 Switching signal for system temperature limit value.
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
OUTx changes its switching state if it is above or below the set switching limits
(SPx, rPx). The following switching functions can be selected:
Hysteresisfunction/normallyopen:[OUx]=[Hno](→fig.1).•
Hysteresisfunction/normallyclosed:[OUx]=[Hnc](→fig.1).•
First the set point (SPx) is set, then the reset point (rPx) with the requested differ-
ence.
Windowfunction/normallyopen:[OUx]=[Fno](→fig.2).•
Windowfunction/normallyclosed:[OUx]=[Fnc](→fig.2).•
The width of the window can be set by means of the difference between SPx and
rPx. SPx = upper value, rPx = lower value.

9 Parameter setting
During parameter setting the unit remains in the operating mode. It continues its
monitoring function with the existing parameters until the parameter setting has
been completed.
9.1 General parameter setting
3 steps must be taken for each parameter setting:
1Selection of the parameter
Press [Mode/Enter] until the re-►
quested parameter is displayed.
2Setting of the parameter value
Press [Set] and keep it pressed.►
Current setting value of the param->
eter flashes for 5 s.
After 5 s: Setting value is changed:>
incrementally by pressing the button
once or continuously by keeping the
button pressed.
Numerical values are incremented continuously. For reducing the value: Let the dis-
play move to the maximum setting value. Then the cycle starts again at the minimum
setting value.
3Acknowledgement of the parameter
value
Press [Mode/Enter] briefly.►
The parameter is displayed again.>
The new setting value is stored.
Setting of other parameters
Start again with step 1.►
Finishing the parameter setting
Press [Mode/Enter] several times until the current measured value is displayed or wait►
for 15
s.
The unit returns to the operating mode.>
If [SLoc] is displayed when attempting a modification of a parameter value, the sensor is•
locked via software. This locking can only be removed via a parameter setting software.
In case of parameter setting with the user interface of the ifm Container program, the•
values can be directly entered in the specified fields.
