Service and Maintenance
SITRANS LUT400 requires no maintenance or cleaning under normal operating
conditions.
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
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 the current LUI firmware revision on the LUT400 display.
• If updating the sensor node, view parameter Firmware Revision (3.1.11.) to see
the current sensor node firmware revision.
Complete a Master Reset (3.2.3.) to factory defaults after a successful upgrade of the
sensor node, before re-entering parameters.
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.) on page 205].
