CONNECTION OF STANDARD FUEL SENSOR OF THE VEHICLE
TO THE UNIVERSAL INPUT
Measure the voltage of the fuel sensor; if its power supply is of impulse type, the signal at the output of the
sensor will also be an impulse one with an amplitude of the voltage corresponding to the level of fuel in
the tank. To convert impulses at the sensor output to DC voltage, it is necessary to connect to the Terminal
via a PAM signal converter (Figure 82).
Measure the voltage from the fuel sensor with a full and empty tank. If the tank has a basic shape, removal
of intermediary points or the entire calibration table is not required.
Connect the output of the fuel sensor to the universal input No.1 of the Terminal. Select “Vehicle Sensor”
fuel sensor setting in Omnicomm Con
fi
gurator and press the “Save Settings” button. After applying the
settings, the program will con
fi
gure universal input No.1 into analog mode of operation with preset values
of the maximum and minimum measured quantity.
Install the empty-tank voltage value obtained from the sensor that corresponds to the minimum value of
the measured quantity, and with full tank - the voltage value, corresponding to the maximum value of the
measured quantity, then press “Save Settings”.
Check the display of the current values of the input voltage and the measured value in the settings of the
universal input.
Check the fuel sensor values displayed in the “Monitoring” tab to verify that they are in accordance with the
current value of the measured quantity.
When connecting the standard fuel sensor to the universal input of the Terminal, set operating mode
with the ignition o
ff
to “Collect data when shaking”. Otherwise, the fuel graph will be displayed
incorrectly.
After exporting the XML
fi
le and importing the vehicle in Omnicomm Online, in the vehicle pro
fi
le,
the value of 4095 Cohn must be assigned to the value of the fuel volume in the tank in litres. If the fuel
tank has a complex shape, a calibration table of the tank must be created in Omnicomm Online.

CONFIGURE THE RECEIVED DATA REGARDING THE AMOUNT OF FUEL
IN THE TANK FROM THE CAN BUS OF THE VEHICLE
Connect and set the receiving parameters of the equipment of the vehicle from CAN bus J193 and con
fi
gure
fuel sensor “CAN sensor”.
Check the fuel sensor display values in the “Monitoring” tab, the values of which must be between
0–4095.
When reading the fuel tank level with the CAN bus, set the operating mode of the Terminal when
the ignition is o
ff
to “Collect data when shaking”. Otherwise, the fuel graph will be displayed
incorrectly.
