2 Device description

The KROHNE TT 60 C/R is two-wire universal transmitter with ProfiBus-PA® interface for

o Temperature measurements with resistance thermometers o Temperature measurements with thermocouples o Temperature differential measurements with resistance thermometers o Measurements with potentiometers o Voltage measurements in a range from -10...1000 mV

The transmitter supports two input signals, thus allowing differential, average and redundant measurements and monitoring of sensor aging.

The TT 60 C is optionally available for areas with potentially explosive atmospheres.

The two-wire universal transmitter TT 60 C is designed for installation in a B connection head according to DIN 43729 or larger.

The two-wire universal transmitter TT 60 R is designed for installation on a top-hat rail according to DIN EN 50022 .

The output of all versions of the TT 60 complies with the latest ProfiBus PA® standard for temperature measuring transducers, i.e. Profile 3.0, Class A and B.

The transmitter can be configured using ProfiBus-PA® or an IBM-compatible PC. Configuration of the transmitter using an IBM-compatible PC requires the "ProfiSoft" software.

The Windows-based "ProfiSoft" software can be used to access all functions of the transmitter.

The current software version is available for downloading on our website

http://www.krohne.com/html/dlc/index.shtml.

You can find configuration instructions in the "ProfiSoft" reference manual.

3 Installation

3.1 TT 60 C installation

TT 60 C / TT 60 C are intended for installation in DIN B connection heads or larger. The large ∅ 7 mm / 0.28 inch center hole (see Chapter 6.1.2) facilitates the electrical connection and installation.

ATTENTION!

ATTENTION!ATTENTION!

The TT 60 C may only be installed in a light metal housing whose magnesium component (Mg) does not exceed 6%.

For applications in a safe area, a housing according to IP 54 is recommended.

ATTENTION!

ATTENTION!ATTENTION!

The TT 60 C may only be installed in areas with potentially explosive atmospheres Zone 2 and in safe areas. If it is installed in Zone 2, a housing with at least IP 54 must be used.

In areas with potentially explosive atmospheres Zone 0 and Zone 1, the TT 60 C

must be

used. The transmitter must be supplied with power by an intrinsically safe power supply unit or Zener

barrier outside of the potentially explosive zone.

ATTENTION!

ATTENTION!ATTENTION!

The TT 60 C must be installed in a housing with the protection rating IP 20 or better.

IMPORTANT NOTE!

Ambient temperature considerations The temperature transmitter TT 60 C has been developed for the ambient temperature range

from -40…+ 85°C (-40…+185°F). Please also note that the ambient temperature is also dependent on the temperature category in Sections 6.1.4 and 6.2.4, Ex data of the ambient temperature.

The process temperature is also transferred to the transmitter housing via the protective tube. If the process temperature is close to or exceeds the maximum specified process temperature, then the temperature in the transmitter housing can rise above the maximum permissible ambient temperature.

Always check that the ambient temperature where the transmitter is installed is always within the permissible range. One way to decrease heat transfer via the protective tube is to make the protective tube longer or in general to install the transmitter farther away from the heat source.

The same safety measures can be taken if the temperature is below the specified minimum temperature.
