NOTICE
When connecting 2 sensors ensure that there is no galvanic connection between thesensors (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 eachsensor separately to a transmitter. The transmitter provides sufficient galvanic isolation(> 2 kV AC) between the input and output.

Cable gland or cable entry

LCAUTION
Risk of damage‣ Switch off power supply before installing or connecting the device. Failure to observe
this may result in the destruction of parts of the electronics.
‣ If the device has not been grounded as a result of the housing being installed, werecommended 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 theground terminal as short as possible! Connection of the functional grounding may beneeded for functional purposes. Compliance with the electrical codes of individual
countries is mandatory.
‣ In systems without additional potential equalization, grounding the shield of the
fieldbus cable at more than one point can lead to the occurrence of mains frequency
equalizing currents, potentially causing damage to the cable or its shield. In such cases,
the shield of the fieldbus cable should 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 connectedshould be insulated!
• The terminals for the fieldbus connection are equipped with integrated reverse
polarity protection.
• Cable cross-section: max. 2.5 mm²• A shielded cable must be used for the connection.
Follow the general procedure. →  15.

Ensuring the degree of protection

The device meets all the requirements of IP66/IP67 protection. Compliance with thefollowing points is mandatory following installation in the field or servicing in order toensure that IP66/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 connecting cables used must have the specified external diameter (e.g. M20x1.5,
cable diameter 8 to 12 mm).
• Firmly tighten the cable gland. →  12,  21
• The cables must loop down before they enter the cable glands ("water trap"). This meansthat any moisture that may form cannot enter the gland. Install the device so that thecable glands are not facing upwards. →  12,  21
• Replace unused cable glands with dummy plugs.
• Do not remove the grommet from the cable gland.

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 theinformation 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 thefollowing 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 bymany 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.

Overview of diagnostic information

9.2.1

Displaying diagnostic events

NOTICE
Status signals and diagnostic behavior can be configured manually for certain
diagnostic events. If a diagnostic event occurs, however, it is not guaranteed that themeasured values are valid for the event and comply with the process for the status
signals S and M and the diagnostic behavior: 'Warning' and Disabled'.
‣ Reset the status signal assignment to the factory setting.

If several diagnostic events are pending at the same time, only the diagnostic message
with the highest priority is displayed. Additional pending diagnostic messages are shownin the Diagnostic list submenu →  87. The main feature of the display priority is thestatus signal in the following order: F, C, S, M. If several diagnostic events with the same
status signal are pending, the priority is defined in numerical order of the event number,e.g. F042 appears before F044 and before S044.
Previous diagnostic messages that are no longer pending are displayed →  88inthe Event logbook submenu.

HART device variables The measured values can be freely assigned to the device variables.
Measured values for PV, SV, TV and QV (first, second, third and fourth device variable)• Sensor 1 (measured value)• Sensor 2 (measured value)• Device temperature• Average of the two measured values: 0.5 x (SV1+SV2)• Difference between sensor 1 and sensor 2: SV1-SV2• Sensor 1 (backup sensor 2): If sensor 1 fails, the value of sensor 2 automatically
becomes the primary HART value (PV): sensor 1 (OR sensor 2).
• Sensor switching: If the value exceeds the configured threshold value T for sensor 1,
the measured value of sensor 2 becomes the primary HART value (PV). The systemswitches back to sensor 1 if the measured value of sensor 1 is at least 2 K below T:
sensor 1 (sensor 2, if sensor 1 > T)
• Average: 0.5 x (SV1+SV2) with backup (measured value of sensor 1 or sensor 2 inthe event of a sensor error in the other sensor)

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

55

Technical data

iTEMP TMT162• Callendar van Dusen coefficients (Pt100 resistance thermometer)
The Callendar van Dusen equation is described as:
RT = R0[1+AT+BT²+C(T-100)T³]
The coefficients A, B and C are used to match the sensor (platinum) and transmitter inorder 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 isrequired, the coefficients for each sensor can be determined specifically with the aid ofsensor calibration.
• Linearization for copper/nickel resistance thermometers (RTD)
The polynomial equation for copper/nickel is as follows:
RT = R0(1+AT+BT²)
The coefficients A and B are used for the linearization of nickel or copper resistancethermometers (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 thetransmitter.
Sensor-transmitter matching using one of the methods mentioned above significantly
improves the temperature measurement accuracy of the entire system. This is because thetransmitter uses the specific data pertaining to the connected sensor to calculate themeasured temperature, instead of using the standardized sensor curve data.
1-point adjustment (offset)

2-point adjustment (sensor trimming)
Correction (slope and offset) of the measured sensor value at transmitter input

This menu contains all the parameters that are needed to configure the basic settings ofthe device. The transmitter can be put into operation with this limited parameter set.
n = Stands for the number of sensor inputs (1 and 2)
Backup function
If the option Sensor 1 (backup sensor 2) or Average: 0.5 x (SV1+SV2) with backup isselected in the Assign current output (PV) parameter, the corresponding backup functionis active.
If Sensor 1 (backup sensor 2) is selected, the transmitter automatically switches to sensor
2 as the primary measured value in the event of a sensor 1 failure. The measured value of
sensor 2 is used as PV. The 4 to 20 mA signal is not interrupted. The status of the faulty
sensor is output via HART. If a display unit is connected, a diagnostic message is shown
there.
Three scenarios can occur if Average: 0.5 x (SV1+SV2) with backup is selected:• If sensor 1 fails, the average corresponds to the measured value of sensor 2, the
4 to 20 mA signal is not interrupted and a diagnosis is output via HART.
• If sensor 2 fails, the average corresponds to the measured value of sensor 1, the
4 to 20 mA signal is not interrupted and a diagnosis is output via HART.
• If both sensors fail at the same time, the transmitter follows the set failure mode and adiagnosis is output via HART.
The Reset sensor backup parameter defines how the transmitter behaves after the sensor
error has been rectified.

Automatic selection

The transmitter automatically switches back to sensor
1 after the sensor error on sensor 1 has been rectified
and sensor 1 is used as PV.

After the sensor error has been rectified, thetransmitter automatically switches back to the averagevalue and this is used as the PV.

Manual selection

After the sensor error at sensor 1 has been rectified,
the transmitter resumes normal operation only upon
manual confirmation via the Reset backup button in
the Diagnostics menu, with sensor 1 used as PV.
Alternatively, you can restore normal operation byswitching the transmitter off and on again. Until
confirmation, sensor 2 is used as PV and a diagnosis is
output via HART.

Sensor error adjustment (sensor trimming)
Sensor trimming is used to adapt the actual sensor signal to the linearization of theselected 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 samelevel 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↓
2. Set the Sensor trimming parameter to the Customer-specific setting.
↓
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.
↓
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 thetemperature actually measured at the input, the transmitter internally calculates a correction factor which is
now used to linearize the input signal.
↓
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.
