Installation instructions
ATEX / IECEx
The installation, commissioning, maintenance and repair of
devices in potentially explosive atmospheres must only be
carried out by appropriately trained personnel. Works may be
carried out only by persons, whose training has included
instructions on different types of protection and installation
techniques, concerned rules and regulations as well as general
principles of zoning. The person must possess the appropriate
competences for the type of work to be conducted.
When operating with combustible dusts, comply with
EN 60079-31.
The safety instructions for electrical apparatus in potentially
explosive areas must be in accordance with Directive
2014/34/EU (ATEX) and IEC 60079-14 (Installation of electrical
equipment in potentially explosive areas).
Comply with the applicable regulations for the protection of
employees to ensure safe operation.
IP protection rating of housing
The temperature transmitter and LCD indicator Type AS must be
installed according to the ‘intrinsic safety’ IP rating such that an
IP rating of at least IP 20 is achieved in accordance with
IEC 60529.
Perform installation according to the ‘non-sparking’ (nA) IP
rating or the ‘increased safety’ (ec) IP rating such that an IP
rating of at least IP 54 is achieved in accordance with IEC 60529.

… Installation instructions
Electrical connections
Grounding
If, for functional reasons, the intrinsically safe circuit needs to be
grounded by means of a connection to the potential
equalization, it may only be grounded at one point.
Intrinsic safety installation check
If transmitters are operated in an intrinsically safe circuit, proof
that the interconnection is intrinsically safe must be provided in
accordance with IEC/EN 60079-14 as well as IEC/EN 60079-25.
The supply isolators / DCS inputs must feature intrinsically safe
input protection circuits in order to eliminate hazards (spark
formation).
In order to provide proof of intrinsic safety, the electrical limit
value must be used as the basis for the EC-type examination
certificates for the equipment (devices); this includes the
capacitance and inductance values of the cables.
Proof of intrinsic safety is said to have been provided if the
following conditions are fulfilled when a comparison is carried
out in relation to the limit values of the equipment:

Installation in a potentially explosive atmosphere
Transmitters can be installed in all kinds of industrial sectors.
Potentially explosive systems are divided into zones,
meaning that a wide range of different instruments are also
required. For this, pay attention to the country-specific
guidelines and certificates!
Note
Ex relevant specifications must be taken from the EC-type
examination certificates and other relevant certificates that
apply in each case.
With transmitters for PROFIBUS PA and FOUNDATION

Installation instructions
FM / CSA
The installation, commissioning, maintenance and repair of
devices in areas with explosion hazard must only be carried out
by appropriately trained personnel.
The operator must strictly observe the applicable national
regulations with regard to installation, function tests, repairs,
and maintenance of electrical devices. (e. g. NEC, CEC).
IP protection rating of housing
The temperature transmitter and LCD indicator Type A and
Type AS must be installed such that an IP rating of at least IP 20
is achieved in accordance with IEC 60529.
Electrical connections
Grounding
If, for functional reasons, the intrinsically safe circuit needs to be
grounded by means of a connection to the potential
equalization, it may only be grounded at one point.
Intrinsic safety installation check
If transmitters are operated in an intrinsically safe circuit, proof
that the interconnection is intrinsically safe must be provided in
accordance with IEC/EN 60079-14 as well as IEC/EN 60079-25.
The supply isolators / DCS inputs must feature intrinsically safe
input protection circuits in order to eliminate hazards (spark
formation).
In order to provide proof of intrinsic safety, the electrical limit
value must be used as the basis for the EC-type examination
certificates for the equipment (devices); this includes the
capacitance and inductance values of the cables.
Note
When operating the transmitter in Zone 0, the compatibility of
the device materials with the surrounding atmosphere must be
guaranteed.
Encapsulation material used for the transmitter:
Polyurethane (PUR), WEVO PU-417

Installation in a potentially explosive atmosphere
Transmitters can be installed in all kinds of industrial sectors.
Potentially explosive systems are divided into zones,
meaning that a wide range of different instruments are also
required. For this, pay attention to the country-specific
guidelines and certificates!
Note
Ex relevant specifications must be taken from the EC-type
examination certificates and other relevant certificates that
apply in each case.
With transmitters for PROFIBUS PA and FOUNDATION
Fieldbus H1 applications, FISCO interconnection methods can be
used.
Commissioning
The commissioning and parameterization of the device may also
be carried out in potentially explosive atmospheres using a

TTH300 HEAD-MOUNT TEMPERATURE TRANSMITTER | OI/TTH300-EN REV. G 15
4Design and function
Digital transmitters are communication-ready devices with
microprocessor-controlled electronics. They conform to the
requirements of IP rating IP 20 and are suited for integration
into DIN A and DIN B sensor heads.
With HART® transmitters, an FSK signal is superimposed on the
4 to 20 mA output signal in accordance with the HART standard
to facilitate bidirectional communication.
With PROFIBUS PA® transmitters, communication takes place in
accordance with PROFIBUS-MBP (IEC 61158-2), PROFIBUS PA
Profile 3.01.
In the case of the FOUNDATION Fieldbus® transmitter,
communication takes place in accordance with FOUNDATION
Fieldbus H1 (IEC 61158-2), ITK version 6.x (from SW-Rev. 1.02.00,
previously ITK 5.x).
The transmitters can be configured using various tools / drivers.
Status and measured values can also be queried. This includes
DTM, EDD and FDI package of Field Information Manager (FIM).
These tools provide an event monitor and a configuration
monitor for HART devices from SW-Rev. 3.00. This allows critical
events such as exceeding or falling below specified limit values
and configuration changes to be output and logged. See the
HART interface description (COM/TTX300/HART).
As an option, the transmitter can be fitted with a type A or a type
AS LCD indicator. Type AS is used exclusively for visualizing
current process values. Type A also supports the option of
configuring the transmitter. It is recommended that you use this
combination.
The electrical connection between the LCD display and
transmitter is provided by a 6-pin flat ribbon cable with a plug
connector. The LCD display can only be operated when
connected to transmitters that have an LCD display interface.
Input functionality
Sensor Redundancy
To enhance system availability, the TTH300 has two sensor
inputs.
The second sensor input can be used redundantly for both
resistance thermometers (2 x three-wire circuit or 2 x two-wire
circuit) and thermocouples or a combination of both. If a
combination of both is used, the resistance sensor must be
connected to channel 1 and the thermocouple to channel 2, see
Electrical connections on page 21.
In the case of HART devices, the failure of a sensor can be
signaled with a configurable analog alarm pulse, see the HART®
interface description (COM/TTX300/HART).
Devices with PROFIBUS PA®, FOUNDATION Fieldbus® and
HART® to SW-Rev. 1.03
Sensor redundancy / sensor backup for increased availability
In the case of sensor redundancy (sensor backup), the
temperature is always measured with both sensors and the
mean value is calculated from this if the sensors are identical.
This value is provided at the output of the transmitter. If the
sensors are not identical, the measured value of channel 1
(resistance thermometer) is output. If one sensor fails, the
temperature measurement of the remaining sensor is
transmitted bumplessly to the output of the transmitter.
A corresponding diagnostic message is available via DTM, EDD,
FDI Package (FIM) or on the LCD display. The measured value
remains available and maintenance measures can be taken at the
same time.
Devices with HART® from SW-Rev. 3.00
Extended configuration options are available for redundant
operation.
The redundancy behavior can be configured for
• increased availability (default setting ex works for
redundancy),
• increased safety and
• increased accuracy (output of the mean value).

remain in the default setting ex works (“Maintenance Required”).

TTH300 HEAD-MOUNT TEMPERATURE TRANSMITTER | OI/TTH300-EN REV. G 17
Sensor drift monitoring
If two sensors are connected, sensor drift monitoring can be
FDI Package (FIM) enabled via DTM, EDD or
The sensor drift monitoring can be activated for the following
sensor types:
• 2 × resistance thermometer (RTD), two-wire circuit
• 2 × resistance thermometer (RTD), three-wire circuit
• 2 × resistors (potentiometer), two-wire circuit
• 2 × resistors (potentiometer), three-wire circuit
• 2 × thermocouple
• 2 × voltages
• 1 × resistance thermometer (RTD), two-wire circuit, and
1 × thermocouple
• 1 × resistance thermometer (RTD), three-wire circuit, and
1 × thermocouple
• 1 × resistance thermometer (RTD), four-wire circuit, and
1 × thermocouple
To activate sensor drift monitoring, the transmitter must first
be configured for the sensor types referred to above. Following
this, the maximum permissible sensor deviation must be
configured, e.g., 1 K.
Since sensor response times may differ slightly, it is then
necessary to configure a limit time period during which the
sensor deviation has to constantly exceed the maximum set.
If the transmitter registers a larger sensor deviation over the
defined period of time, the diagnostic response configured in
accordance with NE 107 is carried out (tools and LCD display).
Sensor drift monitoring with redundancy operation (devices
with PROFIBUS PA®, FOUNDATION Fieldbus® and HART® to SW-
Rev. 1.03)
If drift monitoring is performed for similar sensors (2 ×
resistance thermometers or 2 × thermocouples), the mean value
from both sensors is mapped on the output signal of the
transmitter as a process variable in redundancy mode.
If a thermocouple is used for drift monitoring of a resistance
thermometer, the resistance thermometer must be connected to
channel 1 and the thermocouple to channel 2 (see Electrical
connections on page 21). The measured value of channel 1
(resistance thermometer) is mapped as a process variable at the
transmitter output.
Sensor drift monitoring with redundancy operation (devices
with HART® from SW-Rev. 3.00)
If a thermocouple is used for drift monitoring of a resistance
thermometer, the resistance thermometer must be connected to
channel 1 and the thermocouple to channel 2 (see Electrical
connections on page 21).
The transmitter output signal always corresponds to the
configured redundancy behavior, see Sensor Redundancy on
page 15.
Note
Before configuring the maximum permissible sensor deviation
with regard to drift monitoring, sensor calibration should be
carried out with reference to the sensor channel 1 value using the
TTH300DTM, for example.
Sensor error adjustment in accordance with Callendar-
Van Dusen
Under normal circumstances, the standard Pt100 characteristic
curve is used for resistance thermometer measurement.
However, recent advances in technology now mean that
maximum measuring accuracy can be achieved where necessary
by carrying out individual sensor error adjustment.
Sensor characteristic curves are optimized by using a Pt100
polynomial in accordance with IST-90 / IEC 751, and EN 60150,
and by applying A ,B, C, or Callendar-Van Dusen coefficients.
With the help of the DTM, EDD or FDI package (FIM), these
sensor coefficients (Callendar-Van Dusen) can be adjusted and
stored in the transmitter as a CVD characteristic curve. Up to
five different CVD characteristic curves can be stored for HART
and PROFIBUS PA, while up to two CVD characteristic curves can
be stored for FOUNDATION Fieldbus.
