Preparing for Installation
Product Completeness Check
1) Open up the packaging. Check completeness as per the datasheet. In case the product does not match the set of components listed in the passport, such a mismatch is resolved by the manufacturers or their representatives.
2) Perform visual check of the Product. The Product must have no visible damages. In case a damage is found, the Product must be replaced at the manufacturing facility.
Selection of Location to Install the Product
1) The product should be installed, depending on geometric shape of the tank, at the locations shown in the figures (Figure 1, Figure 2, Figure 3). Product installation at these locations ensures fuel level independence of vehicle inclination.
2) If the Product cannot be installed in any of places specified in Figures (Figure 1, Figure 2, Figure 3), the installation place must be as close to any of the specified as possible.
3) Product installation at the locations other than shown in the figures (Figure 1, Figure 2, Figure 3), may cause fuel level dependence on vehicle inclination. For example, for vehicles operating on the high-relief landscape this will mean either overrated or underrated fuel level values.
Installation of two products in one fuel tank allows to significantly reducing fuel level dependence on vehicle inclination. Two products should be installed at the locations shown in the figures (Figure 4, Figure 5)
Selection of Location to Install BIS 20240 (LLS20230)
1) Installation of BIS 20240 must be carried out outside of explosion hazard zone, on a smooth surface (e.g. cabin).
2) While selecting the location for installation, take into consideration the length of the cable intended to connect stabilitron-based spark protection unit BIS 20240 with an external device (e.g. FMS).
Note. Connection of BIS 20240 with fuel level sensor LLS 20230 should be made only by cable KTZ-XX produced by Omnicomm, where XX – cable length (which can be chosen within the range from 10 to 25m).
Preparation of the Fuel Tank for Product Installation
1) When preparing the holes for installation of LLS fuel level sensors:
- If the fuel tank is used for diesel fuel, it is recommended to fill the tank with diesel fuel to the full before drilling holes — this will minimize the vapor content inside.
- If the fuel tank is used for gasoline, it should be steamed.
- When drilling holes without preliminary steaming (appropriate only for tanks used for diesel fuel without any corrosive impurities), it is recommended to coat bimetal bits or drill with grease oil or lithium grease, which will prevent sparking during drilling.
- If the tank filler neck can be dismantled, tank steaming is not required. Dismantle the tank filler neck and perform installation works far from the fuel tank.
2) Prepare the fuel tank for fitting works following the manufacturer's specification and other safety regulations appropriate to this type of works.
3) Determine the fuel tank type and prepare it accordingly. Fuel tank types:
a. Plastic or metal tank with the wall thickness under 3 mm
The tanks which shape corresponds with the figure (Figure 2) should be prepared in accordance with Appendix E. Prepare the tank for fixing the product by rivets.
Drill holes in the tank: the central hole - by a bi-metal crown ø35mm and mounting holes - by a drill ø7mm as shown in the figure (Figure 7).
It is not recommended to use self-tapping screws to fix the product onto a metal or plastic tank with the wall sickness under 3mm. This type of fixation cannot ensure reliability of product attachment to the tank.
b. Metal tank with wall thickness over 3mm
Prepare the tank for product installation on a threaded joint.
The tanks which shape corresponds with the figure (Figure 2) should be prepared in accordance with Appendix E.
Drill holes in the tank: the central hole - by a bi-metal crown ø35mm and mounting holes - by a drill ø4mm as shown in the figure (Figure 8).
c. Plastic tank with wall thickness over 3 mm
Drill holes in the tank: the central hole - by a bi-metal crown ø35mm and mounting holes - by a drill ø4mm as shown in the figure (Figure 9).
Product Cutting to Match the Specific Fuel Tank
1) Measure the depth of the tank by moving a measuring bar down into the central hole intended for the sensor.
2) On the working length of the product L, measure length L1 equal to the depth of the tank minus 20mm.
Minimum allowable length of the measuring probe cutting is 150 mm.
3) Cut the product at length L1 by a hack-saw so that the line of the cut is strictly perpendicular to the longitudinal axis of the product (Figure 10).
4) Fill the 1/4 to 1/5 of the sealing cap with a sealant (supplied). Recommended sealants are listed in the Appendix J.
5) Put the plastic isolating cap included into the product delivery set on the central rod of the product.
Note: When using the sensor without cutting, it is necessary to take off the rubber transportation cap and put on the plastic isolating cap using sealant.
Setting the Product with Omnicomm Configurator
Run Omnicomm Configurator. In the window (Figure 13) select equipment — “Sensor”.
If the message “Equipment not found” is displayed in the main window, try changing connection configuration or operation mode.
Perform calibration with fuel which the fuel level sensor will operate in.
1) Pour fuel into the measuring container
2) Immerse the sensor in fuel, to the full length of the measuring probe
3) Wait for the green indicator “Stable” to appear. Press “Full” to set the value corresponding to a full tank
4) Take the sensor out of the container and wait while fuel will be flowing off the measuring probe for 1 minute. Press “Empty” to set the value corresponding to an empty tank
5) Press “Save”
Configuring General Settings
“Settings” tab, “Configurable Parameters” section:
“Network address” (1 to 254) – set the sensor network address. If several sensors are connected to one external device, each of them should have unique network addresses.
“Max. level (1…4095)” — select the maximum sensor reading. Default value – 4,095.
“Min. level (0…1023)” — select the minimum sensor reading. Default value – 0.
“Filtration” – set the output signal filtration parameters:
- “No” – no filtration. Used for filtration by an external device.
- “Minimum” filtration is used when the device is installed in stationary fuel storages and non-mobile machinery
- “Average” filtration is used when the vehicle operates under normal road conditions
- “Maximum” filtration is used when the vehicle operates under harsh road conditions
“Automatic data output” – select:
- “No output” – no data output without request
- “Binary” – autonomous binary data output
- “Character” – autonomous character data output
- “Data output interval” (1 to 255 seconds) – set the autonomous data output interval
“Heavy exploitation conditions” mode – switch on to enable additional measurement filtration that considers harsh conditions
“Baud rate” – select data exchange rate when communicating with an external device. Default value – 19200 bit/s.
