Assigned service life Preparation Fuel Tank Preparation 1. Select the location for Omnicomm LLS sensor installation, taking into account the following requirements: The installation location should be as close to the geometric center as possible and be placed at the deepest level of the tank:... - Page 6 Preparation When installed, the sensor should not be in contact with reinforcement ribs and existing equipment inside the tank Installing two sensors in one fuel tank allows to significantly reduce the influence of the vehicle inclination angle on the fuel level: 2.
- Page 7 Preparation The mounting hole diameter depends on the material of the tank: ø 4 mm – for metal tanks with wall thickness over 3 mm (cut M5 thread) ø 7 mm – for plastic and metal tanks with wall thickness up to 3 mm (for rivets) ø...

Setting Sensor Preparation 1. Cut the sensor measuring part according to the following recommendations: The length of the sensor measuring probe should be 20mm less than the depth of the tank. The REF channel must be at least 100 mm shorter that the measuring part of the sensor. - Page 9 Setting Connect the Omnicomm LLS 6 AI sensors according to the diagram: Run the Omnicomm Configurator program on your PC.

When operaеing a vehicle with insufficient fuel level in the tank, auto-tuning cannot be performed. “Network address” (1 to 254) – set the network address for the Omnicomm LLS fuel level sensor. When several sensors are connected to one external device, they should have unique network addresses. - Page 13 Register values are transmitted in the following format: uint16 (16-bit unsigned integer), with big-endian byte order (most significant byte first). To configure additional artificial intelligence parameters, click “LLS 6 AI Engineering Settings”. Select preset configurations depending on the type of equipment used. Available options include: Mining machinery, Agricultural machinery, and Custom parameters.

Page 14: Installation And Connection
3 mm, use the self- tapping screws and a seal (one on each self-tapping screw), included in the kit 3. Connect the Omnicomm LLS sensors to an external device as shown in the diagram:... - Page 15 5. Install the fuse in the fuse holder. 6. If necessary, seal the bolt (self-tapping screw) and the connection. Multiple Omnicomm LLS 5 sensors must be connected side-by-side via the RS-485 interface. When installing sensors with a measuring section length greater than 1.5 meters into vehicle fuel tanks, it is recommended to reinforce the measuring section using steel studs and clamps or steel reinforcement bars, as appropriate.

Page 16: Intended Use
Calibration of the fuel tank is necessary to verify the conformity of the digital code issued by the Omnicomm LLS 6 Al sensor to the fuel volume in a particular fuel tank. Calibration of the fuel tank is performed by refueling up the tank – from empty to full, with a certain refueling interval, and recording the Omnicomm LLS 6 Al sensor readings in the calibration table. - Page 17 Intended Use If the sensor reading column is not displayed, press the “Add sensor” button. Select the type of sensor. Specify the network address set for the sensor during the setup.
- Page 18 65534 liters of fuel volume. 10. Press the “Finish calibration” button. 11. Save the calibration table in a calibration file (.ctb), Omnicomm Online (.xml) file, in the Terminal or in the Indicator, by pressing the “Export” button.

Page 19: Sealing
Sealing Sealing For Omnicomm LLS sensors, the sensor housing is sealed with a casing-seal and a connector: 1. Install the casing-seal on the sensor housing. 2. Place the pins in the grooves of the casing-seals, making sure that they are positioned with the smaller diameter towards the jut of the casing, and push them all the way in. - Page 20 Sealing 1. Join Omnicomm LLS 6 connector to the mounting cable until it clicks. 2. Run the flexible part of the seal through the connectors. 3. Run the flexible part of the seal through the hole in the seal body.
