5.1 Configuring the in-head version
DANGER!
To avoid electric shocks and destructions or damages of the device, assure that all electrical
connections comply with the instructions within the chapter "Electrical connections".
DANGER!
Only perform the configuration described in this section if no sensor is connected to the
transmitter. Otherwise you could damage the cable insulation during soldering, furthermore the
cables could handicap during soldering.
INFORMATION!
In the standard delivery condition the transmitters are not preset. Therefore you have to make a
complete solder pad configuration before using the transmitter for the first time. Also note the
following items:
•
The steps in this section show the complete configuration procedure in the correct order for
new transmitters. The manufacturer strongly recommends to follow this procedure,
otherwise the calibration may not be proper.
•
As an option the manufacturer offers preset transmitters according to the customer's order.
Only in this case the solder pad configuration is not necessary. Though the manufacturer
strongly recommends to perform a calibration in this case.
•
In some cases you have to change the solder pad configuration of a transmitter that has
already been in use. This may be the case e.g. if you must define a new zero point or
measuring span for a new application.
OPERATION 5
Step 1: removing the cover
• Take the transmitter with thumb and forefinger (bottom part lies on the forefinger while the
thumb grips the terminals).
• Grip the cover with the thumb and the forefinger of the other hand beside the holes for the
screws (the cover is not fixed with screws, but it is plugged on the bottom part).
• Pull the cover upwards (refer to previous drawing).

OPTITEMP TT 11 C/R
CAUTION!
You have to choose one sensor break configuration, i.e. you may only set one of the two solder
pads! If you establish both solder pad connections, this could lead to damage or destruction of
the transmitter.
Step 4: setting the sensor break monitoring
1 Lower solder pad: the output signal for sensor break is in this case ≤ 0VDC
2 Upper solder pad: the output signal for sensor break is in this case > 11 VDC
CAUTION!
After the solder pad configuration of the sensor break monitoring is complete, assure that the
cover is on its original place again! The cover prevents electrostatic discharge if the solder pads
are touched inadvertently; furthermore it protects the solder pads against dirt.
The setting of the sensor break monitoring is the last step in the configuration procedure. After
the configuration is complete, a calibration is necessary to achieve the best possible measuring
results.

5 OPERATION
CAUTION!
You have to choose one sensor break configuration, i.e. you may only set one of the two solder
pads! If you establish both solder pad connections, this could lead to damage or destruction of
the transmitter.
Step 4: setting the sensor break monitoring
1 Right solder pad: the output signal for sensor break is in this case ≤ 0VDC
2 Left solder pad: the output signal for sensor break is in this case > 11 VDC
CAUTION!
After the solder pad configuration of the sensor break monitoring is complete, assure that the
cover is on its original place again! The cover prevents electrostatic discharge if the solder pads
are touched inadvertently; furthermore it protects the solder pads against dirt.
OPTITEMP TT 11 C/R
The setting of the sensor break monitoring is the last step in the configuration procedure. After
the configuration is complete, a calibration is necessary to achieve the best possible measuring
results.
5.4 Configuration example (rail-mount version)
• Measuring range: -50...+100°C / -58...+212°F
• Measuring span: 150°C / 270°F
• Sensor break: > 11 VDC
• Zero point: -50°C/ -58°F
5.5 Calibration
DANGER!
To avoid electric shocks and destructions or damages of the device, assure that all electrical
connections comply with the instructions within the chapter "Electrical connections".

INFORMATION!
The manufacturer recommends checking the calibration annually. To achieve the best possible
accuracy, note the following items:
•
All calibration instruments (i.e. resistance decade and amperemeter) must have an accuracy
of at least 0.02%.
•
Assure that the complete solder pad configuration has taken place before the calibration.
•
The calibration has to take place according to the temperature scales ITS 90 (DIN EN 60751).
The resistance decade must have a temperature coefficient setting for platinum (= 0.00385).
•
If you set an input signal that delivers an outputs signal of 12 mA as described in the following
actionsequence, wait circa 15 minutes and check the stability of the output signal afterwards.
Only if the output signal is stable then, the transmitter is ready for calibration.

INFORMATION!
The following calibration procedure is valid not only for the rail-mount transmitter, but also for
the in-head transmitter.
• Connect the power supply and the precision measuring device for current measurement
according to the connection diagram in the chapter "Electrical connections" (the typical power
supply is 24 VDC)..
• Connect the resistance decade according to the connection diagram in the chapter "Electrical
connections".
• Set an input signal that delivers an output signal of 5 V.
• Wait circa 15 minutes and check the stability of the output signal afterwards .Only if the output
signal is stable then, the transmitter is ready for calibration and you can go to the next step!
• Use the resistance decade to set an input signal T
measuring range value (e.g. 100 Ω for a measuring span from 0...+100°C / +32...212°F).
• Use the potentiometer for zero point setting to set exactly a voltage of U
drawing above).
• Use the resistance decade to set an input signal T
measuring range value (e.g. 138.5 Ω for a measuring span from 0...+100°C / +32...212°F).
• Use the potentiometer for the measuring span setting to set exactly a voltage of U
• Repeat the steps 5 till 8 until all of the signals are set exactly.
• Secure the potentiometers with varnish.

7 TECHNICAL DATA
7.1 Resistance thermometer
The transmitter only works together with a measuring insert that has a Pt100 RTD. This kind of
measuring inserts features a temperature-sensitive sensor made from a platinum RTD, whose
value at 0°C / +32°F is 100 Ω. That is where the name "Pt100" comes from.
It is generally valid that the electric resistance of metals increases according to a mathematical
function as the temperature rises. This effect is taken advantage of by resistance thermometers
to measure temperature. The "Pt100" thermometer features a measuring resistance with
defined characteristics, standardised in IEC 60751. The same is true for the tolerances. The
average temperature coefficient of a Pt100 is 3.85 x 10
+32...+212°F.
During operation, a constant current I (≤ 1 mA) flows through the Pt100 RTD, which brings about
a voltage drop U. The resistance R is calculated using Ohm's Law (R=U/I). As the voltage drop U
at 0°C / +32°F is 100 mV, the resulting resistance of the Pt100 thermometer is 100 Ω (100 mV /
1 mA = 100 Ω).
