5.3.1

Cable glands or entries

LCAUTION
Risk of damage‣ 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.
‣ 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 canoccur 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 groundterminal of the housing. The shield that is not connected should be insulated!
Cable specification• A normal device cable suffices if only the analog signal is used.
• A shielded cable is recommended for HART® communication. Observe grounding
concept of the plant.
• The terminals for the fieldbus connection have integrated polarity protection.
• Cable cross-section: max. 2.5 mm²

Ensuring the degree of protection

The device meets the requirements for 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 the sealing groove.
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. →  11,  20
• 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. →  11,  20
• 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.

24

Endress+Hauser

iTEMP TMT142B

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 preselected depending on the operating tool) andentering 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
In the menu: System → User management

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 explained 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 information from the menu Diagnostics → Operating time temperature ranges → Sensor can be processed with the functions under
Guidance → Operating time temperature ranges. With the "Backup & reset" option, the parameters are saved in a separate memory with theactual length of time the sensor was operated in the specific temperature range, and the current values in the menu Diagnostics → Operatingtime temperature ranges → Sensor are reset. This function can be used following a sensor replacement, for example. The separate memory
always only contains the last saved data record. The "Reset" option irrevocably resets the current values in the menu Diagnostics → Operatingtime temperature ranges → Sensor. If the "Create protocol" option is selected, a report is created with the data records for the current lengths oftime and the saved data record. This report is saved in PDF format.
