Service and Maintenance

SITRANS LUT400 requires no maintenance or cleaning under normal operating conditions.
10.1

Firmware updates

To update the LUT400 firmware, please contact your Siemens representative to obtain the
installer (self-executable .exe file). For a complete list of representatives, go to
http://www.siemens.com/processautomation (http://www.siemens.com/processautomation).
Two installers are available: one to update the firmware in the Local User Interface (LUI)
node, and one for the sensor node. One or both may be required, depending on the reason
for the update.
To complete an update, follow steps in the installer:
1. Connect your computer to the SITRANS LUT400 USB port.
2. Before running the .exe installer received from your Siemens representative, note the
computer COM port to which the LUT400 is connected.
3. From your computer, double-click the .exe, and follow the installer steps. The first step
will prompt for Communication Options. These options are set to factory defaults. Ensure
the COM Port is set to that noted in step 2 above. No other changes are required.
4. Follow remaining installer steps.
5. Once complete, verify the update was successful by checking the current firmware
revision:
– If updating the LUI node, recycle the power on the LUT400. On power-up, you will see
– If updating the sensor node, view parameter Firmware Revision (3.1.11.) (Page 240)
Complete a Master Reset (3.2.3.) (Page 242) to factory defaults after a successful upgrade
of the sensor node, before re-entering parameters.
10.2

Transferring parameters using LUT400 display lid

If necessary to transfer parameters from one LUT400 to another, the LUI display maintains a
backup file of the parameters on the device. With this backup file, it is possible to connect
the remote lid to a second LUT400 to transfer parameters.
When the remote lid is connected to a second device, a fault code is displayed to note that
the LUI backup file does not match the configuration file in the sensor. You can then use the
Backup Control parameter to specify that sensor parameters be copied from the LUI backup
to the device [see Backup Control (3.3.2.) (Page 246)].
