Connect the sensor to a PC according to the diagramm:

Connection of Omnicomm <k style='word-break:keep-all;white-space:nowrap'><k style='word-break:keep-all;white-space:nowrap'>LLS-AF</k> 4</k> sensor to a PC

Run the Omnicomm Configurator program on your PC.

Omnicomm Configurator (PC):

Setting of Omnicomm LLS sensor on a PC

The fuel level value is displayed without filtering.

“Empty/Full” Calibration

Perform calibration in the fuel, in which this fuel level sensor will operate.

  1. Fill the measuring container with fuel
  2. Immerse the sensor in the fuel to the full length of the measuring probe
  3. Wait for the green indicator “Stable” to appear. Press the button “Full” to record the value corresponding to a full tank
  4. Remove the sensor from the container and allow the fuel to drain from the measuring probe for 1 minute. Press the button “Empty” to record the value corresponding to an empty tank
  5. Press the “Record into Device” button

Omnicomm LLS-AF 4 Sensor Setting

In the tab “Settings” under “Custom parameters”:

“Filtration” – set the output signal filtration parameters:

  • “No” – filtration is not performed. Applies for cases when filtration is carried out by an external device
  • “Minimum” – filtration applies for cases when the device is installed in stationary fuel storages and objects
  • “Average” – filtration applies for cases when vehicles operate under regular road conditions
  • “Maximum” – filtration applies for cases when vehicles operate under severe road conditions

“Severe operating conditions” – switch on if measurement values require additional filtration with account for severe operating conditions.

“Type of signal” – select “Analog” or “Frequency”.

For the analog signal:

  • “Max. voltage value (5 … 20) V” – set the maximum voltage value. Default value – 5 V
  • “Min. voltage value (0 … 15) V” – set the minimum voltage value. Default value – 0 V

For the frequency signal:

  • “Max. frequency value (100 to 2000) Hz” - set the maximum frequency value. Default value – 2000 Hz
  • “Min. frequency value (30 to 1900) Hz” - set the minimum frequency value. Default value – 30 Hz
  • “Pull-up resistor”. Select “On” if, according to the manufacturer's instructions, the voltage signal is connected to the input of an external device. Select “Off” if the type of the connected signal is “dry contact” or “transistor NPN key”.
