LWARNING
Danger! Electric voltage!
‣The entire connection of the device must take place while the device is de-energized.
‣The protective ground connection must be established before all other connections. If
the protective ground is disconnected, this can be a source of danger.
‣Before commissioning the device, make sure that the supply voltage matches the
voltage specifications on the nameplate.
‣Provide suitable switch or circuit breaker in building installation. This switch must be
provided close to the device (within easy reach) and marked as a circuit breaker.
‣An overcurrent protection element (rated current ≤ 10 A) is required for the power
cable.
• Observe the terminal designation on the side of the device.
• The mixed connection of safety extra-low voltage and dangerous contact voltage to
the relay is permitted.
5.1 Electrical connection
A loop power supply (LPS) is provided for every input. The loop power supply is primarily
designed to supply power to 2-wire sensors and is galvanically isolated from the system
and the outputs.

Endress+Hauser 17
6 Operation
Thanks to the device's simple operating concept, it is possible to commission the device for
many applications without a printed set of Operating Instructions.
The FieldCare operating software is a quick and convenient way of configuring the device.
It contains brief explanatory (help) texts that provide additional information on individual
parameters.
6.1 Operating elements
6.1.1 Local operation at the device
The device is operated by means of the three keys integrated in the front part of the device
• Open the Configuration menu
• Confirm an entry
• Select a parameter or submenu offered in the menu
Within the Configuration menu:
• Scroll step-by-step through the parameters/menu items/characters offered
• Change the value of the selected parameter (increase or decrease)
Outside the Configuration menu:
Display enabled and calculated channels, as well as min. and max. values for all the active
channels.
You can always exit menu items / submenus by selecting "x Back" at the end of the menu.
Leave the setup directly without saving the changes by pressing the ‘-’ and ‘+’ keys
simultaneously for longer (> 3 s).
6.1.2 Configuration via interface & PC configuration software
LCAUTION
Undefined states and switching of outputs and relays while configuring with the
configuration software
‣Do not configure the device when the process is running.
To configure the device using the FieldCare Device Setup software, connect the device to
your PC. You need a special interface adapter for this purpose, e.g. the Commubox
FXA291.
Installing the communication DTM in FieldCare
Before the indicator can be configured, FieldCare Device Setup must be installed on your
PC. The installation instructions can be found in the FieldCare instructions.
Then install the FieldCare device driver according to the following instructions:
1. First install the device driver "CDI DTMlibrary" in FieldCare. It can be found in
FieldCare under "Endress+Hauser Device DTMs → Service / Specific → CDI".
2. The DTM catalog in FieldCare must then be updated. Add the new installed DTMs to
the DTM catalog.

Operation RMA42
18 Endress+Hauser
Installation of the Windows driver for TXU10/FXA291
Administrator rights are required to install the driver in Windows. Proceed as follows:
1. Connect the device to the PC using the TXU10/FXA291 interface adapter.
 A new device is detected and the Windows installation wizard opens.
2. In the installation wizard, do not allow the device to automatically search for
software. For this, select "No, not this time" and click "Next".
3. In the next window, select "Install software from a list or specific location" and click
"Next".
4. In the next window, click "Browse" and select the directory where the driver for the
TXU10/FXA291 adapter is saved.
 The driver is installed.
5. Click "Finish" to finish the installation.
6. Another device is detected and the Windows installation wizard starts again. Again,
choose "No, not this time" and click "Next".
7. In the next window, select "Install software from a list or specific location" and click
"Next".
8. In the next window, click "Browse" and select the directory where the driver for the
TXU10/FXA291 adapter is saved.
 The driver is installed.
9. Click "Finish" to finish the installation.
This completes the driver installation for the interface adapter. The COM port that has
been assigned can be seen in the Windows device manager.
Establishing the connection
Proceed as follows to establish the connection with FieldCare:
1. Firstly, edit the connection macro. For this, start a new project and in the window
that is displayed, right-click the symbol for "Service (CDI) FXA291" and select "Edit".
2. In the next window, to the right of "Serial interface", select the COM port which was
assigned during the installation of the Windows driver for the TXU10/FXA291
adapter.
 The macro is now configured. Select "Finish".
3. Start the "Service (CDI) FXA291" macro by double-clicking it and confirm the
subsequent query with "Yes".
 A search for a connected device is performed and the suitable DTM is opened.
Online configuration is started.
Continue with device configuration in accordance with these Operating Instructions for the
device. The complete Setup menu, i.e. all of the parameters listed in these Operating
Instructions, can also be found in the FieldCareDevice Setup.
In general, it is possible to overwrite parameters with the FieldCare PC software and
the appropriate device DTM even if access protection is active.
If access protection by means of a code should be extended to the software, this
function should be activated in the extended device setup.
For this, select Menu → Setup / Expert → System → Overfill protect → German WHG
and confirm.
