WARNING!
The transmitter has been developed for an operating temperature of -40...+85
To avoid destruction or damage of the device, always assure that the operating temperature or
ambient temperature does not exceed the permissible range. The thermowell also transfer the
process temperature to the transmitter housing. If the process temperature is close to or
exceeds the maximum temperature of the transmitter, then the temperature in the transmitter
housing can rise above the maximum permissible temperature. One way to decrease the head
transfer via thermowell is to install the transmitter further away from the heat source. Inversely
similar measurements can be done if the temperature gets below specified minimum
temperature.

4.1 Safety instructions
DANGER!
All work on the electrical connections may only be carried out with the power disconnected.
DANGER!
Observe the corresponding regulations, declarations of conformity, the type test certificate of
the device and the relevant instructions of this manual.
CAUTION!
Before you connect and operate a transmitter, always note the following items to avoid an
electric shock:
•
For all work on the electrical connections use an electrostatic safe (i.e. grounded)
workplace! In this way you minimize the risk of electrostatic discharge (ESD).
WARNING!
Observe without fail the local occupational health and safety regulations. Any work done on the
electrical components of the measuring device may only be carried out by properly trained
specialists.
ELECTRICAL CONNECTIONS 4
INFORMATION!
Look at the device nameplate to ensure that the device is delivered according to your order.
INFORMATION!
The transmitter is protected against polarity reversal. No damage will occur to the device if the
polarity of the supply voltage is switched. The output will then indicate 0 mA.

5.1 Configuration of transmitter
The transmitters are configured from a PC by using the ConSoft program and a transmitter
configuration kit ICON. For more information refer to
The ConSoft is a PC based graphical user interface for configuration of the transmitters. The PC
configuration software ConSoft is used for configuration, display and documentation.
Full functionality of the transmitter is achieved with ConSoft program version 2.0.0.1 or later.
Consoft is compatible with Windows 2000 SP3, Windows XP (SP2+), Windows Vista, and
Windows 7.The current software versions of ConSoft and the USB interface are available for
downloading on our website.
Configuration can be performed with or without connected power supply.
To make a configuration of the transmitter you need to do following:
1 Install the PC configuration software ConSoft in your PC.
2 Install the driver for the Transmitter configuration kit ICON (included in the Transmitter con-
figuration kit ICON). See User instructions for Transmitter configuration kit ICON. USB inter-
face will indicate correct installation and connection of the transmitter – ICON – PC.
3 Connect the transmitter to your PC via the Transmitter configuration kit ICON.
4 Start the software ConSoft.
5 Click on the icon "Read from the transmitter" or File - "Read from the transmitter". The soft-
ware will identify and connect to the transmitter. A configuration window for the connected
transmitter will open.
6 Enter one of the following options:
- Temperature sensor - Pt100 type (3 different standards)
- Measuring range - lower range value and upper range value
- Error monitoring - upscale or downscale action at sensor break indication
- Error correction - sensor error lower and upper values - compensation for known sensor
errors
- Custom settings - Tag number
7 The selected configuration is downloaded to the transmitter by clicking the icon "Transfer to
transmitter" or File - "Transfer to transmitter"
8 The transmitter begins using the new parameters directly after downloading.

5.2 Factory calibration of transmitter
OPTITEMP TT 20
The transmitters are delivered with a factory configuration Pt100 (α = 0.00385), 3-wire
connection 0...+100 °C / +32...+212 °F or configured according to customer’s requirements.
Due to the long-term drift of max. ±0.1% of span per year, a re-calibration of the
transmitter is normally not needed. Should you for any reason require the re-calibration, the
transmitter must be returned to the factory.
5.3 Sensor Break Monotoring (Up/Down scale)
In case the sensor breakes the transmitter will indicate this by either drop the output <3.6 mA or
lift it to >21.0 mA. The diffrent indication is set in the transmitter via configurator.
5.4 Sensor Short Circuit (Down Scale)
In case the sensor short circuit the transmitter indicates this by dropping the output <3.6 mA and
is default.
5.5 Error Corrections
By setting the measured min and max value for the sensor in given temperature range the
transmitter can compensate sensor errors. This is set with help of the configurator.

7.1 Measuring principles
The kind of the measuring principle depends on the measuring insert that you combine with the
transmitter. In matters of the thermometer type the manufacturer offers two different
measuring inserts, either with a resistance thermometer or with a thermocouple. This
transmitter only supports resistance thermometer.
7.1.1 Resistance thermometer
The measuring insert with a resistance thermometer 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.
TECHNICAL DATA 7
-3K-1
in the range from 0...+100°C/
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).
