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�
• Checkthecompatibilityoftheproductmaterials(→chapter10Technicaldata)
with the media to be monitored in all applications�
3 Functions and features
The unit detects the system temperature in installations�
3.1 Application
To ensure long-term stability and high accuracy of the unit during operation,
please note:
• The probe must be inserted into the measured medium up to the sealing
chamfer�
• Minimum installation depth of the measuring probe: 25 mm�
• The following limit values must be observed:
Measuring range -25 ��� +150 °C -13 ��� 302 °F
Operating temperature process connection -32 ��� +170 °C -25�6 ��� 338 °F
Operating temperature electronics -25 ��� +70 C -13 ��� 158 °F
Storage temperature -40 ��� +85 °C -40 ��� 185 °F
Operating pressure of the medium ≤50bar ≤725PSI
Numberoftemperaturecycles(135K/7s) < 3000

4 Function
• The unit provides a temperature-proportional output signal (4���20 mA or
20...4mA).
• The measuring range is scalable�
• In addition to the analogue signal the unit provides a diagnostic signal� Sensi-
tivity and reaction to different error modes can be programmed� Pin 4 = output
fordiagnosticsignal(pnpornpn).
4.1 Monitoring and diagnostic functions
• By measuring with two different, thermically coupled sensor elements (NTC,
Pt1000)theunitautomaticallydetectsdriftsanderrorsduringtemperature
measurement with great reliability�
• If one of the two sensor elements fails, the temperature measurement can be
continuedwiththesecondelement(backupfunction).
• Very long-term stable measurement is achieved by using high-quality sensor
elements�
4.1.1 Drift / fault monitoring
To monitor the drift the unit compares the temperatures of two different sensor ele-
ments that are thermically coupled in the sensor tip� Normally these temperatures
are identical�
Due to the usual manufacturing tolerances a temperature difference of max� 0�1 K
can also occur with new sensor elements� This does not affect the drift monitoring
function�
If there is a drift in one or both sensor elements, the unit detects them due to the
difference between the two measured temperatures� It compares the difference
withthesetwarning/alarmthresholds(drW,drA→7Parametersetting).Ifthe
thresholds are exceeded, it generates corresponding diagnostic messages and
sets the corresponding status for the process value�
In case of high temperature changes in the measured medium (e�g� filling of a
hotmediumintoacoldvessel)theremaybeashort-termdifferencebetweenthe
temperatures of both measuring elements� This is based on the corresponding
specific response dynamics of the measuring elements� To prevent a drift warning
or alarm in these cases, a delay time can be set by means of the parameter ddr�

4.1.2 Sensor backup / redundancy switching
If one of the two temperature measuring channels fails (e�g� short circuit of one of
thetwosensorelements)thetemperaturecanstillbemeasuredwiththechannel
whichisstilloperational(sensorbackup).However,driftmonitoringisnotpossible
any more�
The characteristics of the unit if one measuring element fails is defined by means
of the parameter drEd�

4.2 Analogue function
• [OU] defines whether the set measuring range is provided as a 4 ��� 20mA
signal([OU]=[I])orasa20...4mAsignal([OU=[InEG]).
• The analogue start point [ASP] defines at which measured value the output
signalis4mA(20mAfor[InEG]).
• The analogue end point [AEP] defines at which measured value the output
signalis20mA(4mAfor[InEG]).
Minimum distance between [ASP] and [AEP] = 50°C / 90°F�
Factory setting Measuring range scaled

Behaviour in case of exceeding or not reaching the limits of the measuring
range
• Measured temperature above the set measuring range:
- The output signal rises to max� 20�5 mA / falls to min� 3�8 mA�
- With a further increase of the measured temperature the diagnostic output of
the sensor provides a warning, the fault number Fnr = 43 is set�
• Measured temperature below the set measuring range:
- The output signal falls to min� 3�8 mA / rises to max� 20�5 mA�
- With a further decrease of the measured temperature the diagnostic output of
the sensor provides a warning, the fault number Fnr = 42 is set�
