 12 Hardware settings via DIP switches

Procedure for setting the DIP switch:

1. Open the cover of the terminal head or field housing.

2. Remove the attached display from the head transmitter.

3. Configure the DIP switch on the rear of the display accordingly. In general: switch to

ON = function enabled, switch to OFF = function disabled.

4. Fit the display onto the head transmitter in the correct position. The head transmitter

accepts the settings within one second.

5. Secure the cover back onto the terminal head or field housing.

Switching write protection on/off

Write protection is switched on and off via a DIP switch on the rear of the optional

attachable display. When write protection is active, parameters cannot be modified. A lock

symbol on the display indicates that the write protection is on. Write protection prevents

any write access to the parameters. The write protection remains active even when the

display is removed. To deactivate the write protection, the display must be attached to the

transmitter with the DIP switch switched off (WRITE LOCK = OFF). The transmitter adopts

the setting during operation and does not need to be restarted.

Turning the display

The display can be rotated 180° using the "DISPL. 180°" DIP switch. The setting is retained

when the display is removed.

Operation options iTEMP TMT71/72

• Operator

The plant operator can only change settings that do not affect the application - and

particularly the measuring path - and simple, application-specific functions that are used

during operation. The operator is able to read all the parameters, however.

• Maintenance

The Maintenance user role refers to configuration situations: commissioning and

process adaptations as well as troubleshooting. It allows the user to configure and

modify 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 to

enter a password. 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 in

the operation of the device:

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

carried out:

• "Post-installation check" checklist→  14

• "Post-connection check" checklist →  17

8.2 Switching on the transmitter

Once you have completed the post-connection checks, 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 with firmware version, hardware version and device revision 4 Displays the sensor configuration (sensor type and type of connection) along with the configured

measuring range 5a Current measured value or 5b Current status message

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 →  35.

The device operates in normal mode after approx. 7 seconds, including the attached

display. Normal measuring mode commences as soon as the switch-on procedure is

completed. Measured values and status values appear on the display.

If the display is attached when the Bluetooth interface is activated, display

initialization is performed twice and Bluetooth communication is disabled

simultaneously.

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 in

which 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, and

contains the following parameters. Its main purpose is to provide information about the

device:

1. The Maintenance role appears in the "Access status" picklist. The Maintenance user

role must first be selected when operating with the SmartBlue App.

 Afterwards, the New password and Confirm new password input boxes appear.

2. Enter a user-defined password that meets the password rules indicated in the online

help.

3. Enter the password again in the Confirm new password input box.

Once the password has been entered successfully, parameter changes, particularly those

that are needed for commissioning, process adaptation/optimization and troubleshooting,

can only be implemented in the Maintenance user role and if the password is entered

successfully.

8.4 Protecting settings from unauthorized access

8.4.1 Hardware locking

The device can be protected against unauthorized access by hardware locking. In the

locking and access concept, hardware locking always has top priority. The device is write-

protected if the keyhole symbol appears in the header of the measured value display. To

disable write protection, switch the write protection switch on the back of the display to

the "OFF" position (hardware write protection). →  19

9.3 Diagnostic information via communication interface

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 the

measured 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.

Status signals

Symbol Event

9.4 Diagnostic list

If two or more diagnostics events are pending simultaneously, only the message with the

highest priority is shown. Additional pending diagnostic messages are shown in the

Diagnostic list submenu . The status signal dictates the priority in which the diagnostic

messages are displayed. The following order of priority applies: F, C, S, M. If two or more

diagnostic events with the same status signal are active simultaneously, the numerical

order of the event number dictates the order of priority in which the events are displayed,

e.g.: F042 appears before F044 and before S044.

9.5 Event logbook

Past diagnostic messages that are no longer pending are shown in the Event logbook

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:

• 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 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:

RT = R0(1+AT+BT²)

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.

Adjustment of the analog output (4 and 20 mA current trimming)

Current trimming is used to compensate the analog output (D/A conversion). Here, the

output current of the transmitter must be adapted so that it suits the value expected at the

higher-level system.

Current trimming does not affect the digital HART® value. This can cause the

measured value shown on the locally installed display to differ marginally from the

value displayed in the higher-level system.

Procedure

2. Install an accurate ammeter (more accurate than the transmitter) in the current loop.

⇓

3. Switch on current output simulation and set the simulation value to 4 mA.
