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. →  6,  14
• 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. →  6,  14
• Replace unused cable glands with dummy plugs.
• Do not remove the grommet from the cable gland.

User roles
Endress+Hauser's role-based access concept consists of two hierarchical levels for the user
and presents the various user roles with defined read/write authorizations derived fromthe NAMUR shell model.

16

Endress+Hauser

iTEMP TMT182B

Operation options• 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. Afterwards, a password can be assigned for the Maintenance userrole to protect this configuration. The Operator user role is not visible when the device isdelivered 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:
In the menu: Guidance → Commissioning wizard: as part of guided device operation

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".

System integration

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 otherthings.

Commissioning

8.1

Post-installation check

Before commissioning the measuring point make sure that all final checks have been
carried out:• "Post-installation check" checklist →  11
• "Post-connection check" checklist→  14

8.2

Switching on the transmitterOnce you have completed the post-connection checks, switch on the supply voltage. The
transmitter performs a number of internal test functions after power-up.
The device works after approx. 7 seconds. Normal measuring mode commences as soon as
the switch-on procedure is completed.

8.3

Configuring the measuring device

Wizards
The starting point for device wizards is in the Guidance menu. Wizards not only queryindividual parameters but also guide the user through the configuration and/or
verification of entire sets of parameters with step-by-step instructions, including
questions, that are comprehensible for the user. The "Start" button can be disabled for
wizards that require specific access authorization (lock symbol appears on the screen).
The following five operating elements are supported for navigation in the wizards:• Start
Only on the initial page: start the wizard and go to the first section• NextGo to the next page of the wizard. Is not enabled until parameters are entered orconfirmed.
• BackReturn to the previous page
• Cancel
If Cancel is selected, the status before the wizard was started is restored• Finish
Closes the wizard and possibility of making additional parameter settings on the device.
Only enabled on the final page.

8.3.1

Commissioning wizard

Commissioning is the first step towards using the device for the designated application.
The Commissioning wizard contains an introductory page (with the "Start" operating
element) and a short description of the content. The wizard consists of several sections inwhich the user is guided step-by-step through the commissioning of the device.
"Device management" is the first section that appears when the user runs the wizard, andcontains the following parameters. Its main purpose is to provide information about thedevice:Navigation

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.
Sensor-transmitter matching using one of the methods mentioned above significantly
improves the temperature measurement accuracy of the entire system. This is because theEndress+Hauser
