Classification of SafetyRelated Notices
This manual contains notices which you should observe to ensure your own per-
sonal safety, as well as to protect the product and connected equipment. These
notices are highlighted in the manual by a warning triangle and are marked as
follows according to the level of danger:
!DANGER
indicates an imminently hazardous situation which, if not avoided, will
result in death or serious injury.
!WARNING
indicates a potentially hazardous situation which, if not avoided, could
result in death or serious injury.
!CAUTION
used with the safety alert symbol indicates a potentially hazardous
situation which, if not avoided, may result in minor or moderate injury.
CAUTION
used without safety alert symbol indicates a potentially hazardous si-
tuation which, if not avoided, may result in property damage.
NOTICE
indicates a potential situation which, if not avoided, may result in an
undesireable result or state.
.NOTE
indicates a reference to a possible advantage when this recommenda-
tion is followed.

.NOTE
These instructions do not purport to cover all details or variations in
equipment, nor to provide for every possible contingency that may
arise during installation, operation or maintenance.
Should further information be desired or should particular problems
arise that are not covered sufficiently for the Purchaser’s purposes, the
matter should be referred to the local Siemens Sales Office.

!WARNING
This device may only be assembled and operated after qualified
personnel has ensured, by providing suitable power supplies, that no
hazardous voltages can get into the device in normal operation or in
the event of a failure of the system or parts thereof.
The device may be operated with high pressure and aggressive
media. Therefore serious injuries and/or considerable material damage
cannot be ruled out in the event of improper handling of the device.
Trouble-free and reliable operation of this device is conditional upon
the proper storage, installation and assembly as well as careful
operation and maintenance.

1 Technical Description
1.1 Range of Application
The SITRANS T3K PA transmitter can be used in all branches. Its compact size
enables it to be installed in the terminal housing with raised cover type B
(DIN 43729) or higher. The following sensors/signal sources can be connected
through its universal input module:
DResistance thermometer
DThermocouples
DResistance based sensor/potentiometer
DDC voltage sources
The useful data – measured values with status as a quality specification and other
parameters – are provided on the PROFIBUS-PA (see chapter 1.3.2, page 64 und
chapter 7, page 104).
Transmitter in the version ”Ignition protection type non-incendive” can be mounted
inside areas with an explosion hazard (zone 2). Transmitter in the ”intrinsically
safe ignition protection type” can be mounted in areas with an explosion hazard
(zone 1) and be used for feeding sensors at zone 0. The conformity declarations
comply with the European standard (CENELEC).
1.2 Product features
DTransmitter with bus connection according to IEC 61158-2 and EN 50170, part 4
DData transmission and transmitter supply via common bus link
DInstallation in terminal housing type B with raised cover (DIN 43729) or higher
DCan communicate through PROFIBUS-PA (profile B, version 3.0); sensor,
measuring range and much more can therefore be programmed.
DQuality data for the measured values: status with limit values
DFixed bus current limiting in the event of an error
DElectrical isolation (test voltage 500 V AC)
DIntrinsically safe version for use in Ex-area

1.3 PROFIBUS connection
The PROFIBUS (Process Field Bus) is an open communication system for
automation technology. A detailed description of its properties can be found in
chapter 7, page 104. The most important information for operation is listed below:
1.3.1 Setting the PROFIBUS address
The PROFIBUS address is set to 126 as standard. It can be set to another value
by the parameter setting tool, e.g. SIMATIC PDM. The set PROFIBUS address
may only be assigned once on the same bus system.
1.3.2 Useful data about PROFIBUS

VZ: sign; 0 = positive, 1 = negative

E: Exponential
The useful data are continuously updated by the cyclic service of PROFIBUS.
This is the measured value in SITRANS T3K PA. It can be a temperature,
resistance or voltage value depending on the configuration. The measured value
is divided into a floating point value (4 bytes) and the appropriate quality indicator
(1 byte).
