2 Transportation and Storage
Store and transport the device only under clean and dry conditions preferably in the origi-
nal packaging. Avoid exposure to shocks and excessive vibrations.
Permissible storage temperature: -40…85 °C
3 Installation and Commissioning
Ensure that the device is suitable for the intended application with respect to temperature
range, pressure range, medium compatibility and process connection.
3.1 Mechanical Installation
Before starting operation, check the process connection carefully for leaks under pressure.
Use gaskets, if required, that are suitable for the process connection and resistant to the
media.
Please note that the permissible operating pressure is specified by the process connec-
tion. An operation outside the standard nominal pressure level, e.g. with Clamp connec-
tions, is only permitted with specially approved mounting elements.
The installation position of the temperature measuring system is freely selectable.

3.2 Electrical Connection
Complete the mechanical installation before you connect the device electrically.
Set up all electrical connections while the voltage supply is switched off.
Functional area IO-Link = 18...32 VDC
Functional area if two switch outputs = 9,6...32 VDC
Nominal voltage = 24 VDC
The auxiliary energy of the temperature transmitter must meet SELV requirements, or op-
tionally an energy-limited power circuit can be used in accordance with Chapter 9.3 of
DIN EN 61010-1 or UL 61010-1.

The transmitter is intended for operation on class A IO-Link ports. Since the “Switch output
2” signal is located at Pin 2, it is not applicable for operation on class B ports.
During installation please take max. cable length of 20 m into consideration.
The temperature transmitter must be connected to the plant's potential equalisation system
via the process connection.

4.1 Maintenance / Service
When properly installed in accordance with applicable specifications, this device is
maintenance-free. However, we recommend an annual recalibration of the device.
In the event of any damage or defect the customer cannot replace or repair any compo-
nents or assemblies.

BA_083 Rev 1C9 Digital transmitter for temperature IO-Link Page 5/24
5 Disassembly
When measuring hot media, make sure that the device has cooled down prior to any dis-
mounting or wear appropriate protective clothing to avoid burns.
Switch off the power supply to the device before disconnecting the electrical connections.
Once this is done, the device may be mechanically removed.
Warning
Opening pressurized lines might cause severe injuries.
Danger of severe injuries or damage

Relieve the process pressure before attempting to remove the device.
Shut off the pressure supply for all feed lines to the device and relieve the
pressure in them.
Warning
Hazardous deposits and residues might remain on opened process connec-
tions and removed devices.
Danger of injury

After the device has been removed, seal off the measuring point and
mark the open process connection accordingly. Consider a possible dan-
ger due to residues when handling the removed device.

6 User Manual
You can download the technical description file (IODD) required for using the pressure
transmitter in the download area of the LABOM website (www.labom.com).
6.1 View in configuration tool
Different entries in the menue structure are possible depending on the configuration tool.
The four areas below are standardised across tools and contain all important parameter
and setting functions:
- Identification, see 6.2
- Parameter, see 6.3
- Observation, see 6.4
- Diagnosis, see 6.5
Outlined below are the detailed menue contents as structured in PACTware 4.1. Other IO-
Link tools have a different parameter structure or display them differently, although the
functionality is identical.
6.2 Menue "Identification"
The parameters displayed here identify the product and manufacturer.

6.3 Menue "Parameter"
In this area, the device is parametrised. The individual parametrisation options are outlined
below.
6.3.1 Section "Measurement / Output"
In this section, the process data format, pressure unit and damping are parametrised.
Figure 3: Section „Parameter – Measurement / Output“ in PACTware 4.1
6.3.1.1 Process data format
The process data format is used to set the number format in which the measuring value is
transmitted.
In the format “floating point”, the measuring value is transmitted as a floating point number.
In the format “integer”, the measuring value is transmitted as an integer number. The two
lowest digits represent two decimal places. E.g. the integer number 199 represents the
measuring value 1.99 (in terms of the current unit).
6.3.1.2 Unit temperature
This is where the temperature measuring unit can be set. This is used as basis when
transmitting the temperature value as part of the process values. Additionally, all parame-
ters with a temperature reference refer to this unit.
Please note that parameters with a temperature reference are not converted automatically
when the unit settings are changed. Example: The zero point offset of 0.1 is saved in the
unit ‘°C’. If the unit is changed to °F, the zero point offset is now at 0.1 °F.
This affects the parameters for adjustment (see 6.3.2) and the switching points (see 6.3.3)
as well as the min/max values (see 6.5.2).
That is why the temperature unit should be parameterised first. After changing the temper-
ature unit, please check the parameters with a temperature reference and reset the
min/max values.

6.3.1.3 Damping
Adjusting the damping function within the range of 0.00 to 100.00 s, avoids that rapid
measured value fluctuations or spikes (input values) are visible in the output signal.
Damping is achieved by a 2nd order digital filter for which the time is set in seconds.
After that set time, 26% of the change in the input value is visible in the output signal. After
the set time has elapsed 4 times, approximately 90% of the change is visible in the output
signal.

6.3.2 "Adjustment" section
In this section, the measuring device can be calibrated and thus optimises measuring ac-
curacy.
6.3.2.1 Sub-section "Temperature correction"
Figure 5: Section „Parameter – Temperature correction“ in PACTware 4.1
In terms of temperature correction, a temperature offset is entered, which acts as the off-
set across the entire measuring span. You can therefore enter it at any reference tempera-
ture you wish.
Expose the instrument to the required reference temperature and read out the temperature
value measured by the instrument (see also 6.4). Now enter the difference using the re-
versed algebraic sign as temperature offset and transfer the value to the instrument.
Please note that the temperature offset value is not displayed in the tool immediately, only
after the device parameter is retrieved again.

6.3.2.2 Sub-section "Adjustment of characteristic curve"
Figure 6: Section "Parameter - Adjustment of characteristic curve" in PACTware 4.1
This feature allows to correct the characteristic curve of the temperature transmitter. In
contrast to temperature correction, the adjustment of the characteristic curve allows to
change the offset and the gradient.
Follow the process below to perform the adjustment of characteristic curve:
1. Apply the lower (as low as possible) reference pressure level to the measuring device
2. Enter the lower target value in the field “Target value lower adjustment point” and trans-
fer it to the device.
3. Press the button “Set actual value to lower adjustment point”. This sets the current ac-
tual value as “actual value lower adjustment point”.
4. Apply the upper (as low as possible) reference pressure level to the measuring device
5. Enter the upper target value in the field “Target value upper adjustment point” and
transfer it to the device.
6. Press the button “Set actual value to upper adjustment point”. This sets the current ac-
tual value as “actual value upper adjustment point”.
7. Activate the adjustment by setting the parameter “Enable adjustment of characteristic
curve” to “on”.
The adjustment of characteristic curve can be performed with any reference temperatures.
For instance, the lower adjustment point of a -40…150 °C device at 0 °C. You can also
choose any reference temperature for the upper adjustment point. However, to achieve a
precise adjustment, the reference values should be as close as possible to the lower and
upper range value.
