iTEMP TMT86• via conventional cable gland →  16
• via fieldbus connector
Risk of damage• Switch off the power supply before installing or connecting the head transmitter.
Failure to observe this may result in the destruction of parts of the electronics.
• Grounding via one of the grounding screws (terminal head, field housing) is
recommended.
• If the shielding of the fieldbus cable is grounded at more than one point in systems
without additional potential equalization, mains-frequency equalizing currents may
occur and cause damage to the cable or shielding. In such cases, the shielding 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 (terminal head, field housing). The shield that is
not connected should be insulated!
• We recommend that the fieldbus not be looped using conventional cable glands. If
you replace even just one measuring device at a later date, the bus communication
will have to be interrupted.

Supply voltage

Connecting to an APL field switch
The device must be used in accordance with the APL port classification:
Hazardous areas: SLAA or SLAC (details in Ex safety instructions)Non-hazardous areas: SLAX connection to an APL field switch with maximum voltage of
15 VDC and minimal output power of 0.54 W. This corresponds to an APL field switch
with APL port classification SPCC or SPAA, for example.
Ethernet-APL power class A (9.6 to 15 VDC, 540 mW)
Maximum power consumption: 0.7 W
Connecting to an SPE switch
In non-hazardous areas, the device can be used with a suitable SPE field switch: The device
can be connected to an SPE switch with a maximum voltage of 30 VDC and a minimum
output power of 1.85 W. The SPE switch must support the 10BASE-T1L standard and the
PoDL power classes 10, 11 or 12 and recognize SPE field devices without an integrated
PoDL module.
The field switch must be tested to ensure that it meets safety requirements (e.g.
PELV, SELV, Class 2).

6.3

Connecting the sensor cables

Terminal assignment of sensor connections
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.

Ensuring the degree of protection

Compliance with the following points is mandatory following installation in the field orservicing in order to ensure that IP67 protection is maintained:• The transmitter must be mounted in a terminal head with the appropriate degree ofprotection.
• The housing seals must be clean and undamaged when inserted into their grooves. The
seals must be dried, cleaned or replaced if necessary.
• 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. →  8,  19
• 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 in such a waythat the cable glands are not facing upwards. →  8,  19
• Replace unused cable glands with dummy plugs.
• Do not remove the grommet from the cable gland.

Operation options

iTEMP TMT86• Operator
The plant operator can only change settings that do not affect the application - andparticularly the measuring path - and simple, application-specific functions that are usedduring operation. The operator is able to read all the parameters, however.
• Maintenance
The Maintenance user role refers to configuration situations: commissioning andprocess adaptations as well as troubleshooting. It allows the user to configure andmodify all available parameters. In contrast to the Operator user role, in the
Maintenance role the user has read and write access to all the parameters.
• Changing the user role
A user role - and therefore existing read and write authorization - is changed by
selecting the desired user role (already pre-selected depending on the operating tool)and entering the correct password when subsequently prompted. When a user logs out,system access always returns to the lowest level in the hierarchy. A user is logged out
either by actively selecting the logout function when operating the device or is logged
out automatically if the device is not operated for a period of over 600 seconds.
Irrespective of this, actions that are already in progress (e.g. active upload/download,
data logging, etc.) continue to be executed in the background.
• As-delivered state
The Operator user role is not enabled when the device is delivered from the factory, i.e.
the Maintenance role is the lowest level in the hierarchy ex-works. This state makes it
possible to commission the device and make other process adaptations without having toenter a password (webserver: 0000). Afterwards, a password can be assigned for the
Maintenance user role to protect this configuration. The Operator user role is not
visible when the device is delivered from the factory.
• Password
The Maintenance user role can assign a password in order to restrict access to device
functions. This activates the Operator user role, which is now the lowest hierarchy level
where the user is not asked to enter a password. The password can only be changed or
disabled in the Maintenance user role. A password can be defined at different points inthe operation of the device:

Device master file (GSD)

In order to integrate field devices into a bus system, the PROFINET system needs a
description of the device parameters, such as output data, input data, data format and data
volume.
These data are available in the device master file (GSD) which is provided to theautomation system when the communication system is commissioned. In addition device
bit maps, which appear as icons in the network structure, can also be integrated.
The device master file (GSD) is in XML format, and the file is created in the GSDML

Configuring the device address via software

The IP address is set via the IP address parameter (System → Connectivity → Ethernet →Properties).

9.3.1

Setting the service IP address

If the IP address of the device is assigned via a software address and this IP address is
unknown, the network connection can be established via the web server by enabling theservice IP address. The service IP address becomes active (ADDR ACTIVE = 1) as soon as
the display is connected to the device and the device is restarted. When the configurationof the measuring device is complete, the "ADDR ACTIVE" DIP switch must be disabled again(0) and the device restarted. After restarting, the measuring device uses the IP address
originally configured, and the device is reconnected to the network.

Commissioning wizard

Commissioning is the first step towards using the device for the designated application.
The commissioning wizard includes a welcome page (with Start operating element) and atable of contents as a brief description. The wizard consists of several sections in which theuser is guided step-by-step through the commissioning of the device.
When the wizard is run, the first section, Device management, contains the following
parameters and serves mainly to provide information about the device:• Device tag• Device name
• Serial number• Extended order code (n) 1
All of the relevant settings concerning the sensor are performed in the next two Sensor
sections. The number of parameters displayed depends on the corresponding settings.
The following parameters can be configured:• Sensor type
• Connection type
• 2-wire compensation• Cold junction• RJ preset value
A password for the Maintenance user role can be assigned in the next section. This isstrongly recommended to protect the device against unauthorized access. The following
steps describe how to configure a password for the " Maintenance" user role for the firsttime.
Access authorization: set up the password for Maintenance1.

Application examples

Two sensors with measuring input (RTD or TC) in remote installation with the following advantages: drift
warning, sensor backup function
Integrated transmitter - 1 x RTD/TC or 2 x RTD/TC for redundancy

Endress+Hauser offers a comprehensive range of industrial thermometers with resistancesensors or thermocouples.
When combined with the temperature transmitter, these components form a complete
measuring point for a wide range of applications in the industrial sector.
The temperature transmitter is a 2-wire device with two measuring inputs. The device not
only transfers converted signals from resistance thermometers and thermocouples, it alsotransfers resistance and voltage signals using the PROFINET® protocol. Power is supplied
via the 2-wire Ethernet connection according to IEEE 802.3cg 10BASE-T1L. The
transmitter can be installed as an intrinsically safe electrical apparatus in Zone 1
hazardous areas. The device can be used for instrumentation purposes in the terminal
head form B (flat face) according to DIN EN 50446.
Standard diagnostic functions• Open circuit, short-circuit, corrosion of sensor cables• Incorrect wiring• Internal device errors• Overrange/underrange detection• Ambient temperature out-of-range detection
Corrosion detection as per NAMUR NE89
Corrosion of the sensor connection cables can cause incorrect measured value readings.

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:• 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.

Technical data

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.

The measured error data corresponds to ±2 σ (Gaussian distribution).

The head transmitter has no display or operating elements. There is the option of using
the attachable measured value display TID10 together with the head transmitter. The
display provides plain-text information on the current measured value and the measuring
point identification. In the event of a fault in the measurement chain, this will be displayed
in inverse color showing the channel ident and error number. DIP switches can be foundon the rear of the display. These enable hardware settings to be made e.g. write protection.
