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.

!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.

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

Floating point representation of the measured value

4 2--16 2--17 2--18 2--19 2--20 2--21 2--22 2--23

VZ: sign; 0 = positive, 1 = negative

M: Mantissa

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).
