Set up configuration parameters as described below.

Auto-Adjustment — enable this option to automatically correct measurements when the dielectric constant of the fuel changes. When auto-adjustment is enabled, level variations caused by fuel thermal expansion are also taken into account, meaning the displayed level will reflect the current temperature.

When using auto-adjustment, consider the following:

• For the Omnicomm LLS sensor to automatically correct its calibration values, the vehicle’s fuel tank must be completely filled during operation.
• When the fuel tank is fully filled, the maximum length of the sensor’s measuring part that remains above the fuel must not exceed 10 cm from the sensor flange.
• If the vehicle is operated with an insufficient fuel level in the tank, auto-adjustment cannot be performed.

To change the scale settings of the LLS sensor:

• Enter the Min scale value (0) and the Max scale value (1023 / 4095) depending on your sensor type.
• Click OK to confirm.

Min. Level (0…4094)

Minimum Reading

Set the minimum reading of the Omnicomm LLS fuel level sensor.

Default value: 0.

Max. Level (1…4095)

Maximum Reading

Set the maximum reading of the Omnicomm LLS sensor.

Adjusting the maximum reading changes the scale division value to match different units of level measurement.

Default value: 4095.

To determine the correct Max scale value:

• Check the sensor label
• Review the passport (datasheet)
• Use the device information displayed automatically in the Omnicomm Configurator.

Important Notes:

• Always ensure the correct scale is set before calibration or parameter reading.
• Selecting the wrong scale may cause incorrect fuel level readings.
• After changing the scale, it is recommended to read parameters again to confirm the update.

Recommendation:

• If you are unsure which scale to enter, press Read in the configurator. The app will automatically retrieve the current scale from the connected sensor.

Cargo and Special Vehicles:

• Passenger Transport
• Stationary Tank
• Other Equipment
• Custom Settings

Select one of the predefined operating modes for the vehicle on which the LLS 6 AI sensor is installed.

To change the network address of an LLS sensor, follow the steps below:

1. Open the Omnicomm Configurator application and connect to the LLS sensor.

2. In the settings menu, locate the field “Network address.”

3. Set the network address of the LLS fuel level sensor to a value between 1 and 254. The network address of each Omnicomm LLS sensor connected to the same external device must be unique.

4. After entering the correct value, tap OK to save the new network address.

The LLS sensor will now operate using the updated network address.

Filtration helps stabilize the output signal and reduce noise caused by:

• fuel movement inside the tank
• vehicle vibrations
• electrical interference

Maximum filtration is recommended for:

• vehicles operating on rough roads
• machinery with strong vibration
• situations where highly stable readings are required

Lower filtration may be used when faster reaction to fuel level changes is needed.

To change the filtration settings in the LLS sensor:

1. Open the Filtration menu in the Omnicomm Configurator.

2. Select the desired filtration level (for example, Maximum).

3. Click OK to save the setting.

The baud rate must match the configuration of the receiving device or control system for correct communication.

Common baud rates for LLS sensors are 9600, 19200, 38400, and 57600 bps.

To change the baud rate (connection speed) in the LLS sensor:

• Scroll down to the Baud Rate or Connection Speed setting in the Omnicomm Configurator.
• Select the desired baud rate according to your terminal or system requirements.
• Click OK to save the new setting.

After changing the baud rate, reconnect the device to ensure proper communication.

To change the data output mode of the LLS sensor:

1. Open the Data Output settings in the Omnicomm Configurator. 2. Select the desired output format according to your terminal or system requirements:

• No output – disables data transmission
• Binary – transmits raw binary data
• ASCII / Character coded – transmits data in readable text format

Click OK to save the selection.

The output interval determines how frequently the LLS sensor sends data to the connected device.

Shorter intervals provide more frequent updates but may increase data traffic.

Longer intervals reduce traffic and power consumption but delay updates.

To change the output interval of the LLS sensor:

1. Scroll down to the Output Interval setting in the Omnicomm Configurator.

2. Select the desired interval value according to your terminal or system requirements.

3. The valid range is 1–255 seconds.

Click OK to save the setting.

After changing the interval, verify that the connected system correctly receives data at the new rate.

To configure the LLS sensor for severe operation conditions or tough road conditions:

1. Open the Severe Operation / Tough Road Conditions setting in the Omnicomm Configurator.

2. Switch the setting to ON.

It is recommended to keep this setting ON when the vehicle frequently operates under harsh conditions.

For normal road conditions, this setting can remain OFF to allow faster response times.

3. Click OK to save the configuration.

1. Click on Calibration to proceed for tank calibration process.

2. Select Refuelling and press Start calibration button to proceed for next step.

3. Define the “Filling step, Liters” according to the volume of the measuring tank, and drop the volume in to the tank.

4. Click on Add a line.

5. Click on Add a line every time after filling the fixed quantity.

Finally click on finish calibration to save the settings.
