Mechanical specifications

Section 5.1 - Mechanical specifications

It is important to be careful when screwing the cover on or off. The thread surface must be free of any grains,
pellets or other impurities as these can cause the cover to seize or damage the threads.

! Never use force to screw on the cover.

Should it be necessary to open the connection head cover after operation in maximum temperature, please be
aware that the cover may be blocked (does not give when attempting to open it by hand). In this case, keep the
cover under tension with your hand and hit the cover gently with a rubber hammer.

Optical Buttons

10

Section 10.1 - Optical buttons

The user interface features 3 optical buttons: , and . The buttons can be operated both with or without gloves1.
The buttons are immune to interference from ambient light sources and other panel meters (e.g. other TXUN-FD devices
mounted in close proximity).
Additionally, the optical buttons are adaptive, meaning that they will adapt to wear and e.g. dirt left on the surface.
The buttons work both with and without a front cover mounted.
If a rapid increase in optical reflection occurs, e.g. from mounting the cover or from dust/dirt on the glass, the buttons may
activate. If a key-press is detected for a period of more than 70 seconds, it is assumed to be a failure key-press and the
adaptive functionality will re-initialize in order to restore correct keypad functionality. This re-initialization can also be done
by repowering the device.

^

^

Operating the optical buttons

The optical buttons are used for operating and programming the TXUN-FD. They offer multi-functionality depending on
whether you press or long-press them. With the exception of the calibration and simulation menus (see the section Display
menu), the display will return to the monitor view if no key-press is registered within one minute.

In monitor view: switch to next process variable.

^

Elsewhere: increase the value of the selected parameter (except if device is write-protected).

^

In monitor view: switch to previous process variable.

Elsewhere: decrease the value of the selected parameter (except if device is write-protected).

Accept chosen value and proceed to next parameter

Hold Progressively increase (scroll) the numerical value (except if device is write-protected)

^

^

Hold Progressively decrease (scroll) the numerical value (except if device is write-protected)

Hold Ignore the chosen value and return to previous parameter

^

Hold + Unlock the monitor view and enter configuration menu

Key presses are reflected in the symbols bar with the following symbols:

Up button is pressed

Down button is pressed

Enter button is pressed

Display

The 96 x 64 pixel display can be rotated in 90-degree increments for easy vertical or horizontal viewing. The adjustable
backlight enables you to view process values in all lighting conditions without an external light source, and it can be
configured to flash if an error occurs. Both the optional backlight and the flashing error backlight can be selected as red or
white, or turned off completely.

Display views

The appearance of the display will change to reflect the state of the TXUN-FD. This allows for easy and intuitive operation,
status indication and guides you in configuring the device.

1 Dark colored gloves can cause reduced sensitivity.
2 If error color (see the section Display menu) is set to red or white and the display backlight is flashing, the first key press cancels the

flashing backlight.

Device and Sensor Status Indication

Section 12 - Device and sensor status indication

The TXUN-FD is capable of displaying diagnostics information for the sensors and the device. These diagnostics can be
divided into 4 categories: Sensor status, sensor errors, device status and device errors.

Sensor status

Sensor 1 exceeds upper sensor limit IN.HI

Sensor 1 exceeds lower sensor limit IN.LO

Sensor 2 exceeds upper sensor limit IN.HI

Sensor 2 exceeds lower sensor limit IN.LO

Display Menu

Section 13 - Display Menu

Exiting the monitor view allows you to configure the TXUN-FD, using the optical buttons (see the section Operating the
optical buttons). The display menu is divided into 2 sections: Basic configuration and Advanced configuration. The
advanced configuration menu is sub-divided into 9 sections: Display, Tags, Calibration, Simulation, Sensor, HART, Write­protect, Language and HART Revision.

If the TXUN-FD menu has been PIN code-protected by setting a PIN code different from 0000 in the display menu, the
correct PIN code must be entered to proceed to the desired configuration menu. The code 2008 will always give access to
the menu.

The menu can be temporarily locked because it is receiving a configuration on the HART interface or because it is
synchronizing configuration parameters with the internal device.

If the TXUN-FD has been write-protected it is still possible to proceed to the menu, but no changes can be made, and it is
not possible to save the configuration.
It is possible to change the write-protection state (enabled/disabled), but the correct write-protect password must be
entered when prompted.

Calibration

(only if Write-protection is disabled)

The device can be process-calibrated in two points to fit a given input signal. A low input signal (not necessarily 0%) is
applied and the actual value is entered. Secondly a high input signal (not necessarily 100%) is applied and the actual value
is entered. If you accept to use the calibration (by selecting Yes in the Save menu) the device will work according to the
new adjustments. You can return the device to factory calibration points by selecting Reset Calibration from the
Calibration menu. Please note that while performing a calibration the programming mode will not time out.

Changing the HART protocol version

Changing the HART protocol version

It is possible to change the HART protocol revision of the device by means of the display, utilizing the OMset software and a
HART modem or other HART configuration tools such as handheld HART terminals.

Changing the HART revision using the display and the optical buttons

Changing the revision is done from the HART revision view under the Advanced menu. Use the or optical buttons to select
the desired HART revision. Press the button to accept the revision and change to the Save view. Select Yes and press to
acknowledge the change or No to cancel.

Changing the HART revision using the OMset software

Select either TXUN-FDH5 or TXUN-FDH7 depending on which protocol revision the TXUN-FD is currently running. Click on the
HART tab and then on Device Password / Write Protection / Protocol…. In the newly opened window check the “Change
protocol to HART #” (# being the desired revision) then acknowledge by pressing the OK button.

The following warning appears:

Click Yes to accept the changes.

Changing the HART revision using a handheld terminal

• Drive the TXUN-FD device Online and enter Device setup – Diag/Service.

• Select Write protection and Write protect by entering “********” (eight stars).

• Select New password - type “********” (eight stars) and then “HARTREV5” or “HARTREV7” depending on the desired
revision

• Select Write enable and enter “-CHANGE-”.

Connection of transmitters in multidrop mode

17

Connection of transmitters in multidrop mode

The outputs of maximum 63 transmitters can be connected in parallel for a digital HART 7 communication on 2-wires. For HART
5 the outputs of maximum 15 transmitters can be connected in the same way.

Before they are connected, each transmitter must be configured with a unique polling address ranging from one to 63 (HART 7) or
15 (HART 5). If two transmitters are configured with the same address, both will be excluded. The transmitter must be configured
for multidrop mode (with a fixed output signal of 4 mA). The maximum current in the loop is therefore 252 mA (HART 7) or 60
mA (HART 5).

The communication is done by means of either a HART communicator or a HART modem.

The OMset configuration software can configure the individual transmitter for multidrop mode and provide it with a unique
polling address.

Retrofit

Retrofit

The TXUN-FD can be retrofitted with any TXUN transmitter. This allows for easy use of existing devices. The following gives you
a short guide on how to perform this task.

Before proceeding please refer to the section Assembly and disassembly for information on extracting and reassembling the
main unit. Then follow the three easy steps below.

Al

RF

B

A

NB. The fixation bracket (marked B on the drawing) is not interchangeable between
the aluminum and stainless steel housing. Check the bottom right-hand corner for
identifier (Al for aluminum and RF for stainless steel).

1. On the TXUN, remove the terminal 1 and 2 screws using a screwdriver.

2. Attach the connector pins to the TXUN connector 1 and 2.
Tighten the screws using a nutdriver or a socket wrench with Across Flats (A/F) of

5 mm and an outer diameter of no more than 7 mm.
Screw torque on connector pins = 0.4 Nm.

3. Mount the device in the main unit, making sure the connectors meet.

The first time power is applied to the retrofitted TXUN-FD, it will synchronize with
the configuration parameters from the attached TXUN. This process will take
approximately 30 seconds and during this NEW.DEV will appear in the display.

A/F = 5

Nutdriver / socket wrench head

Warning:

For Ex installation the customer must assure that the installed transmitter has all the
necessary approvals applicable for the place of installation.
Once a TXUN unit which has been fitted into the TXUN-FD, it must not be taken out
and used in other applications.

The entity concept

The Transmitter must be installed according to National Electrical Code (ANSI-NFPA 70) and shall be
installed with the enclosure, mounting, and spacing segregation requirement of the ultimate application.

Equipment that is FM-approved for intrinsic safety may be connected to barriers based on the ENTITY
CONCEPT. This concept permits interconnection of approved transmitters, meters and other devices in
combinations which have not been specifically examined by FM, provided that the agency's criteria are
met. The combination is then intrinsically safe, if the entity concept is acceptable to the authority having
jurisdiction over the installation.

The entity concept criteria are as follows:

ices, other than barriers, must not be a source of power.

The maximum voltage Ui(V

) and current Ii(I
