NOTICE

When connecting 2 sensors ensure that there is no galvanic connection between the
sensors (e.g. caused by sensor elements that are not isolated from the thermowell).
The resulting equalizing currents distort the measurements considerably.

The sensors must remain galvanically isolated from one another by connecting each

sensor separately to a transmitter. The transmitter provides sufficient galvanic isolation
(> 2 kV AC) between the input and output.

Risk of damage

Switch off power supply before installing or connecting the device. Failure to observe

‣

this may result in destruction of parts of the electronics.
If the device has not been grounded as a result of the housing being installed, we

‣

recommended grounding it via one of the ground screws. Observe the grounding
concept of the plant! Keep the cable shield between the stripped fieldbus cable and the
ground terminal as short as possible! Connection of the functional grounding may be
needed for functional purposes. Compliance with the electrical codes of individual
countries is mandatory.
If the shielding of the fieldbus cable is grounded at more than one point in systems that

‣

do not have additional potential equalization, mains frequency equalizing currents can
occur that damage the cable or the shielding. In such cases the shielding of the fieldbus
cable is to be grounded on one side only, i.e. it must not be connected to the ground
terminal of the housing. The shield that is not connected should be insulated!

• The terminals for the fieldbus connection have integrated polarity protection.

• Cable cross-section: max. 2.5 mm²

• A shielded cable must be used for the connection.

Follow the general procedure. →  15.

5.5 Ensuring the degree of protection

The measuring system meets all the requirements of IP67 protection. Compliance with the
following points is mandatory following installation in the field or servicing in order to
ensure that IP67 protection is maintained:

•

The housing seals must be clean and undamaged when inserted into their grooves. The
seals must be dried, cleaned or replaced if necessary.

• All housing screws and screw caps must be firmly tightened.

• The cables used for connection must be of the specified outside diameter (e.g. M20x1.5,

cable diameter 8 to 12 mm).

• Firmly tighten the cable gland. →  12,  20

• The cables must loop down before they enter the cable glands ("water trap"). This means

that any moisture that may form cannot enter the gland. Install the device so that the
cable glands are not facing upwards. →  12,  20

• Cable glands not used are to be blanked off using the dummy plugs provided.

• Do not remove the grommet from the cable gland.

6.1 Overview of operation options

Operators have a number of options for configuring and commissioning the device:

• Configuration software →  27

HART® functions and device-specific parameters are primarily configured via the
Fieldbus interface. Special configuration and operating programs are available from
various manufacturers for this purpose.

• Miniature switch (DIP switch) and proof-test button for various hardware settings

–

Hardware write protection is activated and deactivated via a miniature switch (DIP
switch) on the electronics module.

– Proof-test button for testing in SIL mode without HART operation. Pressing the button

triggers a device restart. The proof test checks the functional integrity of the
transmitter in the SIL mode during commissioning, in the event of changes to safety­related parameters or generally at appropriate intervals.

33.

7.3

Supported HART® commands

The HART® protocol enables the transfer of measuring data and device data between
the HART® master and the field device for configuration and diagnostics purposes.
HART® masters such as the handheld terminal or PC-based operating programs (e.g.
FieldCare) need device description files (DD, DTM) which are used to access all the
information in a HART® device. This information is transmitted exclusively via
"commands".

There are three different types of command

•

Universal commands:
All HART® devices support and use universal commands. These are associated with the
following functionalities for example:
– Recognition of HART® devices
– Reading digital measured values

• Common practice commands:
Common practice commands offer functions which are supported and can be executed by
many but not all field devices.

• Device-specific commands:
These commands allow access to device-specific functions which are not HART

®

standard. Such commands access individual field device information, among other
things.

Before commissioning the measuring point make sure that all final checks have been
carried out:

• "Post-installation check" checklist,

• "Post-connection check” checklist, →  15

8.2 Switching on the transmitter

Once the final checks have been successfully completed, it is time to switch on the supply
voltage. The transmitter performs a number of internal test functions after power-up. As
this procedure progresses, the following sequence of messages appears on the display:

Step Display

1 "Display" text and firmware version of the display

2 Firm logo

3 Device name (scrolling text)

4 Firmware, hardware version, device version and device address

If the switch-on procedure is not successful, the relevant diagnostic event, depending on the cause,



is displayed. A detailed list of diagnostic events and the corresponding troubleshooting instructions
can be found in the "Diagnostics and troubleshooting" section .

→  12

The device operates in normal mode after approx. 30 seconds! Normal measuring mode
commences as soon as the switch-on procedure is completed. Measured values and status
values appear on the display.

8.3 Enabling configuration

If the device is locked and the parameter settings cannot be changed, it must first be
enabled via the hardware or software lock. The device is write-protected if the lock symbol
is shown on the display.

To unlock the device

• either switch the write protection switch on the electronics module to the "OFF" position
(hardware write protection), or
deactivate the software write protection via the operating tool. See the description for

•
the 'Define device write protection' parameter. →  83

When hardware write protection is active (write protection switch set to the "ON"
position), write protection cannot be disabled via the operating tool. Hardware write
protection must always be disabled before software write protection can be enabled or
disabled via the operating tool.

Sensor adjustment Sensor-Transmitter-Matching

RTD sensors are one of the most linear temperature measuring elements. Nevertheless,
the output must be linearized. To significantly improve temperature measurement
accuracy, the device allows the use of two methods:

Endress+Hauser 53

Technische Daten iTEMP TMT162

RT= R0[1+AT+BT²+C(T-100)T³]

RT= R0(1+AT+BT²)

• Callendar-Van-Dusen coefficients (Pt100 resistance thermometer)
The Callendar-Van-Dusen equation is described as:

The coefficients A, B and C are used to match the sensor (platinum) and transmitter in
order to improve the accuracy of the measuring system. The coefficients for a standard
sensor are specified in IEC 751. If no standard sensor is available or if greater accuracy is
required, the coefficients for each sensor can be determined specifically with the aid of
sensor calibration.

• Linearization for copper/nickel resistance thermometers (RTD)
The polynomial equation for copper/nickel is as follows:

The coefficients A and B are used for the linearization of nickel or copper resistance
thermometers (RTD). The exact values of the coefficients derive from the calibration
data and are specific to each sensor. The sensor-specific coefficients are then sent to the
transmitter.

Sensor transmitter matching using one of the methods explained above significantly
improves the temperature measurement accuracy of the entire system. This is because the
transmitter uses the specific data pertaining to the connected sensor to calculate the
measured temperature, instead of using the standardized sensor curve data.

1-point adjustment (offset)

Shifts the sensor value

2-point adjustment (sensor trimming)

Correction (slope and offset) of the measured sensor value at transmitter input

Current output adjustment Correction of 4 or 20 mA current output value (not possible in SIL mode)

Operating influences

The measured error data correspond to ±2 s (Gaussian distribution), i.e. 95.45%.

"Sensor trimming" submenu

Sensor error adjustment (sensor trimming)

Sensor trimming is used to adapt the actual sensor signal to the linearization of the
selected sensor type stored in the transmitter. Compared to sensor transmitter matching,
sensor trimming only takes place at the start and end value and does not achieve the same
level of accuracy.

Sensor trimming does not adapt the measuring range. It is used to adapt the sensor
signal to the linearization stored in the transmitter.

Procedure

1. Start

ß

2. Set the Sensor trimming parameter to the Customer-specific setting.

ß

3. Using a water/oil bath, bring the sensor connected to the transmitter to a known and stable temperature. A
temperature which is close to the set start of the measuring range is recommended.

ß

iTEMP TMT162 Operating menu and parameter description

4. Enter the reference temperature for the value at the start of the measuring range for the Sensor trimming
lower value parameter. Based on the difference between the specified reference temperature and the

temperature actually measured at the input, the transmitter internally calculates a correction factor which is

now used to linearize the input signal.

ß

5. Using a water/oil bath, bring the sensor connected to the transmitter to a known and stable temperature
close to the set end of the measuring range.
