2.4 Installation instructions
2.4.1 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 ignition protection types and
installation techniques, concerned rules and regulations as
well as general principles of zoning. The person must possess
the relevant expertise for the type of works to be executed.
When operating with combustible dusts, EN 60079-31 must
be complied with.
The safety instructions for electrical apparatus in potentially
explosive areas must be complied with, in accordance with the
directive 2014/34/EU (ATEX) and e.g. IEC
60079-14 (Installation of equipment in potentially explosive
atmospheres).
To ensure safe operation, the respectively applicable
requirements must be met for the protection of workers.

8 OI/TTH300-EN Rev. D | TTH300
2.4.3 Electrical connections
Earthing
If, for functional reasons, the intrinsically safe circuit needs to
be earthed by means of a connection to the potential
equalization, it may only be earthed 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!
NOTICE
Ex relevant specifications must be taken from the EC-type
examination certificates and other relevant certificates that
apply in each case.

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).
3.2.2 IP protection rating of housing
The temperature transmitter and LCD indicator types A and
AS must be installed such that the IP rating of at least IP20 is
achieved in accordance with IEC 60529.
3.2.3 Electrical connections
Earthing
If, for functional reasons, the intrinsically safe circuit needs to
be earthed by means of a connection to the potential
equalization, it may only be earthed 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!
NOTICE
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.
3.3 Commissioning
The commissioning and parameterization of the device may
also be carried out in potentially explosive atmospheres using
a handheld terminal that has been approved accordingly under
consideration of an intrinsic safety installation check.
Alternatively, an Ex modem can be connected to the circuit
outside the potentially explosive atmosphere.
3.4 Operating instructions
3.4.1 Protection against electrostatic discharges

4Function and System Design
Digital transmitters are communication-ready devices with
microprocessor-controlled electronics. They conform to the
requirements of housing IP rating IP20 and are suitable for
integration into DIN A and DIN B sensor heads.
With HART transmitters, an FSK signal is superimposed on the
4 … 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.
With FF transmitters, communication takes place in
accordance with FOUNDATION Fieldbus H1 (IEC 61158-2),
ITK Version 5.x.
The transmitters can be configured, polled, and tested using a
DTM or an EDD.
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 LC display interface.
4.1 Input functionality
4.1.1 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 for a mixture of the two.
Sensor redundancy (or sensor backup) always involves
measuring the temperature of the two sensors and calculating
the mean value on the basis of this.
This value is provided at the output of the transmitter. Should
a sensor fail, the temperature measurement for the sensor that
remains in operation is provided at the output of the
transmitter.
A relevant diagnostic message is provided via the EDD or
DTM, or shown on the display. The measured value remains
available and maintenance measures can be taken at the
same time.
4.1.2 Sensor drift monitoring
When two sensors are connected, sensor drift monitoring can
be activated via the EDD or DTM.
The sensor drift monitoring can be activated for the following
sensor types:
— 2 x resistance thermometer (RTD), two-wire circuit
— 2 x resistance thermometer (RTD), three-wire circuit
— 2 x resistor (potentiometer), two-wire circuit
— 2 x resistor (potentiometer), three-wire circuit
— 2 x thermocouple
— 2 x voltage
— 1 x resistance thermometer (RTD), two-wire circuit, and
1 x thermocouple
— 1 x resistance thermometer (RTD), three-wire circuit, and
1 x thermocouple
— 1 x resistance thermometer (RTD), four-wire circuit, and
1 x 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 records a larger sensor deviation during the
defined time period, a HART, EDD, and DTM diagnostic
notification - "Maintenance required" - is generated according
to NE 107. At the same time, diagnostic information is shown
on the LCD display.
If drift monitoring is used for the same types of sensor (2 x
Pt100 or 2 x thermocouple), the mean value calculated from
the two sensors is mapped to the transmitter's output signal
as a process variable in redundancy mode.
If a thermocouple is used for Pt100 drift monitoring, the Pt100
sensor (see chapter "Electrical connections" on page 11) must
be connected to channel 1 and the thermocouple to
channel 2.
The measured value from channel 1 (Pt100) is mapped to the
transmitter output as a process variable.
NOTICE
Before configuring the maximum permissible sensor
deviation for drift monitoring, sensor adjustment with respect
to the sensor channel 1 value must be carried out with the
help of the TTH300 DTM.

TTH300 | OI/TTH300-EN Rev. D 13
4.1.3 Sensor error adjustment according to 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.
The DTM or EDD can be used to set and store these sensor
coefficients (Callendar-Van Dusen) in the transmitter as a CVD
characteristic curve. Up to five different CVD characteristic
curves can be stored for HART and PROFIBUS PA, and up to
two can be stored for FOUNDATION Fieldbus.

By adding the resistance R250 , the minimum input terminal
voltage U2min: U1min ≤ U2min - 22 mA x (R + R250) can be
increased.
For HART functionality, use supply isolators or DCS input
cards with a HART mark. If this is not possible, a resistance of
≥ 250  (< 1100 Ω) must be added to the interconnection.
The signal line can be operated with or without earthing. When
establishing a ground connection (minus side), make sure that
only one side of the terminal is connected to the equipotential
bonding.
Unless the profile HART protocol Rev. 7 is exclusively selected
during the ordering process, the device normally supports the
profile HART HART protocol Rev. 5 in the delivery
status. Subsequently user can change over to the profile
HART HART protocol Rev. 7 over a miniature switch. See
chapter for more details "Hardware settings" on page 22.
