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!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!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!

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.

The illustration above shows a typical ProfiBus architecture. Field devices with low power
consumption (e.g. pressure and temperature transmitters) are fed via the two-wire bus. Signal
transmission is likewise via the bus.
In the case of installations in areas without potentially explosive atmospheres, up to 32 devices
can be connected per segment, depending on the power rating of the segment coupler.
In the case of installations in areas with potentially explosive atmospheres, normally 10 devices
can be connected per segment.

ATTENTION!
ATTENTION!ATTENTION!
No PC may be connected to a transmitter in areas with potentially explosive atmospheres.
If you wish to configure the transmitter with the PC, this must be done outside of the area with a
potentially explosive atmosphere or by means of communication via ProfiBus.
If the transmitter is configured with the PC, a configuration cable and an adapter from the
configuration set (order number see Chapter 7.1) must be used as the connection between the
PC and the transmitter.
An ATEX certified cable must be used for transmitters bearing the symbol.

5.2.1 Smart Sense
If the appropriate measuring sensors are provided (an additional wire in the sensor), the
transmitter can continuously monitor the insulation resistance of the sensor, including the
connection wires. This function (Smart Sense) is possible for resistance thermometers and
thermocouples. If the insulation resistance is too low, the measured result will be incorrect and
a message will be generated via ProfiBus.
This function requires configuration with the "ProfiSoft" software via a PC or via the ProfiBus.
5.2.2 Monitoring of sensor aging
If a resistance thermometer or a thermocouple with two sensors is used, the TT 60 can be used
to monitor the aging of the sensor. The transmitter compares the measured values of the two
sensors. Aging is indicated if the differential between the measured values is too great. In this
case a message is generated via the ProfiBus. For further information, see the "Profisoft"
manual.
