Safety Guidelines
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
Danger
indicates that death or severe personal injury will result if proper precautions are not taken.
Warning
indicates that death or severe personal injury may result if proper precautions are not taken.
Caution
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
Caution
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
Notice
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The device/system may only be set up and used in conjunction with this documentation. Commissioning and
operation of a device/system may only be performed by qualified personnel. Within the context of the safety notes
in this documentation qualified persons are defined as persons who are authorized to commission, ground and
label devices, systems and circuits in accordance with established safety practices and standards.
Prescribed Usage

2.1 Diagnosis
In order to provide some information about the device to the control application and the
human interface, there are diagnosis parameters in the device. The diagnosis parameters
have a bit string data type and there is a mask parameter indicating which diagnosis is
supported by the device.
2.2 Diagnosis of the Device Characteristics
In the Physical block the DIAGNOSIS parameter has the information about the “alerts” into
the device (for instance, device not initialized, power up, factory init, hardware failure, etc).
The DIAGNOSIS_MASK has the diagnosis supported by the device.

SITRANS TH400 PROFIBUS® PA
10 Configuration Manual, 02/2007, A5E01039143-01
The Transducer Block

3.1 Transducer Block
contains all of the manufacturer-specific parameters that define how the SITRANS TH400
Transmitter functions. Selections such as setting of input type, engineering units, defining the
dual functionality when using the dual input, and so forth, are performed in the Transducer
Block.
The transducer block in SITRANS TH400 allows the user to select a large number of
sophisticated functions. Therefore, the configuration of the transmitter must be carried out
with the greatest possible care.

The data of the Transducer Block Parameter List are grouped as follows:
AI_TRANSDUCER Block, chapter 3.8
• Sensor characterising parameters, chapter 3.8.1
• RTD / resistor specific parameters, chapter 3.8.2
• Thermocouple specific parameters, chapter 3.8.3
• Output conditioning parameters, chapter 3.8.4
• Output parameters, chapter 3.8.5
• Diagnostic parameters, chapter 3.8.6
• Sensor error detection parameters, chapter 3.8.7

• Custom Polynomial linearisation, chapter 3.9.4
PR_CUST_PRIV Block, chapter 3.10
• PR_CUST_PRIV Block, chapter 3.10.1
Note
All product-specific parameters are set off in grey background in the TB Parameter List. In
order to configure these parameters, the files mentioned in the introduction must be available
to the application software.

3.3 Default configuration
SITRANS TH400 PROFIBUS® PA
12 Configuration Manual, 02/2007, A5E01039143-01
3.3 Default configuration
The default configuration of SITRANS TH400 will suite the customer’s demand in many
cases. The configuration task has thus been reduced considerably.
The individual default configurations are shown in the TB Parameter List, but in short the
default configuration is as follows:
– Pt100 acc. to the standard
EN 60751
(chapter 3.8.1 LIN_TYPE, value 102)
– °C
(chapter 3.8.1 PRIMARY_VALUE_UNIT, value 1001)
– 3-wire connection
(chapter 3.8.2 SENSOR_CONNECTION, value 1)
– Only sensor 1
(chapter 3.8.4 SENSOR_MEAS_TYPE, value 220)
– No sensor error detection
(chapter 3.8.7 SENSOR_WIRE_CHECK_1, value 3)
3.4 Your application set up.
In the Transducer block all parameters marked R / W can be adapted to suit any
measurement in temperature, ohm or mV. The way of presenting the file data mentioned in
the introduction varies greatly from one piece of application software to the other. Some
programs show drop down menus in which the parameters must be selected via text lines,
while other programs require the user to type in the numerical value of the parameter
selection.
