Fuel level sensors
In the settings open “Inputs” tab.
Select the following values for RS-485 interfaces:
- Off: The interface is not in use.
- Omnicomm LLS/LLD: The interface is used to connect Omnicomm LLS fuel level sensors or Omnicomm LLD fuel volume indicator.
Now refer to “Fuel Level Sensors”:
Data Source: Select the type of fuel level sensors. Here are the available options:
- Digital LLS: This is for Omnicomm LLS fuel level sensors;
- Vehicle Sensor: This is for the vehicle's standard factory fuel sensor;
- CAN Bus: This is for connecting to the CAN bus;
- Off: Select this option if you do not need to monitor your fuel level.
“If you are connecting either Omnicomm LLS or Omnicomm
- Filters: Enter the size of the internal filter you intend to use. Here are the available filter options:
- Filters Off: Filtering is performed only according to the Omnicomm LLS sensor settings;
- Weak: Use it when installing sensors in stationary fuel storage objects or low-mobility equipment;
- Medium: Use it for vehicles that operate under normal road conditions;
- Strong: Use it for vehicles that operate under normal and heavy road conditions;
- Maximum: Use it for vehicles that operate under heavy road conditions and/or when employing a vehicle's default factory fuel sensor with analog output.
Connect the Omnicomm LLS 30160 fuel level sensor according to the figure below:
Universal inputs (UIs) are designed to connect additional equipment with impulse, voltage, analog, or frequency outputs and monitor its operations.
“Universal input”, select “On”.
“Operation mode”, select “Potential”.
“Transmit 1-Wire Sensor Values Instead of UI Values”, check this box if you need to transmit data from additional equipment connected via the 1-Wire interface.
“Potential input switching-on voltage threshold”, select the voltage threshold value that must be reached by the Terminal to record the sensor as “On”. The default value is 9 V.
“Pullup”, select “On”, if you're working with “open collector” or contact type sensors.
“Invert Input Signal”, select “On” for sensors with open contacts or contacts that lock as a result of a specific action or event.
“Current Voltage”, displays the Terminal's universal input voltage value.
“Current Value”, displays if the additional equipment is on or off.
“Send SMS upon triggering”, select “On”, if you want the Terminal to send SMS text messages when a voltage universal input is activated.
“Equipment name”, enter a parameter controlled.
Potential types of sensors: contact or non-contact discrete sensors.
Connect contactless sensors (capacity, induction, optical or magnetic) and N-P-N type sensors with 'open collector' output according to the figure below:
Connect contact sensors according to the figure below:
You can use standard factory equipment elements (such as on/off buttons, end switches/sensors that are activated by changes in temperature or pressure values, etc.) as contact sensors, or any additionally installed sensors. We recommend to first examine your options of connecting to a standard device or element, and only installing an additional sensor in case that this is not possible.
Sensors with analogue output:
Measured Variable Minimum Value, set the minimum value for the variable measured by the sensor, defined in appropriate units. Voltage Associated With Minimum Value, set the voltage value that should be associated with the minimum value of the measured variable. Measured Variable Maximum Value, set the maximum value for the variable measured by the sensor, defined in appropriate units.
Voltage Associated With Maximum Value, set the voltage value that should be associated with the maximum value of the measured variable.
Current Universal Input Voltage, displays voltage value at Terminal's universal input.
Current Universal Input Value, displays current value of the measured variable.
Equipment Name, enter the name of the monitored parameter.
Types of analogue sensors:
Standardised current output
Standardised voltage output
Sensors with frequency output
Universal Input, select “On”.
Operation Mode, select “Frequency”.
“Transmit 1-Wire Sensor Values Instead of UI Values”, check this box if you need to transmit data from additional equipment connected via the 1-Wire interface. This will prevent data transmission from the universal input.
“Pull-up”, select “On” if you're working with “open collector” or contact type sensors.
Current Universal Input Value, displays the current value of the measured variable.
Omnicomm LLD Indicator
Open the “Settings” menu and select the “Additional Equipment” tab:
Data Mode, select the data source that should be used to display values on the Omnicomm LLD indicator.
Here are the available options:
- GPS Speed Tracking, displays vehicle speed.
- Universal Input, displays state of or value at the Terminal's universal input, depending on the additionally connected equipment.
Open the “Settings” menu and select the “Additional Equipment” tab:
Panic Button, enable or disable monitoring the panic button state.
Send SMS Messages Upon Activation: Enable or disable outgoing SMS text messages whenever the panic button is pressed.
Connect the panic button according to the figure below:
The panic button shall be installed on the vehicle's front panel, or anywhere inside the vehicle cabin that is convenient for use. Once you've chosen the installation place, drill a 12-mm hole, mount the button and secure it with a ring and a tab washer.
Open the “Settings” menu and select the “CAN” tab:
Refer to the list and select the parameters whose values you need to display in Omnicomm Online by ticking the box in the 'Use' column appropriately. If you need to add parameter readings from the CAN bus that are missing from this list, go to Omnicomm Configurator and click on 'Add'. You will be taken to the following screen:
Length: Select the data packet length. Here are the available options: 1, 2, 3, or 4 bits; 1, 2, or 4 bytes.
PGN: Enter the parameter group number that determines the content of each specific message according to SAE J1939. You can choose a number from 1 to 262,143.
Offset: Enter the offset value in relation to the basic address of the bit storage area. You can choose values from 0 to 63.
SPN: Enter the parameter code according to SAE J1939. You can choose between values from 0 to 4,294,967,295.
Use: Check if you want the read this parameter from the CAN bus.
Click on “Save”.
Connect to the vehicle's CAN bus via the wireless CAN reader (or CAN alligator clip).
When using wireless CAN readers, connect the Terminals according to the diagram below:
Use the “Monitoring” tab to check how the fuel sensor readings are displayed; the available value range is from 0 to 4,095.
If you choose to obtain data on fuel volume in the tank from CAN bus readings, select the “Collect Data During Joilting” Terminal operation mode for the event of ignition “Off”.
Otherwise, the fuel chart will display inaccurate information.
