Ultrasonic Fuel Sensor The following instructions are for sensors models with maximum measurement range 300mm, 500mm and 1000mm. If you are installing sensors of greater range (tank height > 1000m) please refer to the sensor manual that accompanies the sensor or contact support. 8.1 Working Principle Fuel sensor is used to monitor the fuel level present in the diesel generator tank. Ultrasonic sensors direct a ultrasonic sound pulse towards the fuel surface, which is then reflected by the fuel surface. The time 21

27 travelled by the ultrasonic pulse is calculated, and the distance of the fuel surface from sensor is found. This is converted to a linear 4-20 ma sensor output. 8.2 Wiring Connection 22

28 Cable Colour Color Code Definition Brown BN Power Supply typical (+UB) Blue BU Power Supply Ground(-UB) Black BK Current output(4-20ma) White WH Teaching input Grey GY Synchronization 8.3 Sensor Installation A. Basic Tools Required Drill machine, measuring tape, Hole saw, screwdriver etc. B. Drilling and sensor mounting First, clean the tank residual oil, dirt dust etc. then rinse with water to make sure there is no gas or oil content in the tank. Select the drilling point on the center of the oil tank surface Corner installation will cause inner wall reflection and erroneous reading. Sensor sound wave must have sufficient diameter to cause no inner wall reflections. Minimum distance from side walls should be 100mm for 1000 mm height tanks. This should be increased for tanks with greater height. Use hole saw to drill point on selected fixed point, when drilling, please avoid the iron filing falling into the tank (drill hole as per sensor diameter). You may use a strong magnet to prevent fillings falling inside the tank. Mount ultrasonic sensors with plastic gasket to avoid acoustic energy absorption through the sensor body. 23

29 Drill sensor mounting holes to match the sensor gasket holes. Provide a sun shade for outside installations to prevent the sensor body from overheating and causing erroneous measurements. The sensor body should stay equal to the ambient air temperature so the sensor s built-in temperature compensation can work correctly. 300mm Sensor 500 mm Sensor 24

30 1000 mm Sensor 8.4 Sensor Calibration Program the sensors as per the generator tank height. The calibration for the operating range is done by applying the supply voltage, -UB or +UB to the Teach-In Input to the sensor. The supply voltage must be applied to the Teach-In input for at least 1s. LEDs indicate whether the sensor has recognized the target during the calibration procedure. 1. Mount the sensor on the tank and ensure the fuel level is at minimum level in tank. 2. Power ON the sensor by supply power on connecting positive terminal +UB and negative -UB. 3. Calibrate by applying -UB to the Teach-In input,white wire (yellow LED flashes) 4. Disconnect the Teach-In input from -UB to save the minimum level calibration 25

31 5. Now fill the tank with fuel to the maximum level. 6. Calibrate for maximum level by applying +UB to the Teach-In input (yellow LED flashes) 7. Disconnect the Teach-In input from +UB to save the maximum level calibration. 26

Check settings entered and also confirm it from your SIM service provider. 2. Insert the SIM card into your mobile phone. 3. Check if you can access internet with this SIM card. If not contact your network operator and get internet activated on this SIM. 4. If internet is working reprovision the device from the EnergyLogicIQ cloud platform. 5. Check if an SMS is delivered to your device. If not check if you can send SMS to the SIM from any other mobile. If not contact your network operator. 6. If in step 4 you received an SMS save it on the SIM card. Remove the SIM card and insert it back into the IoT Cloud Connector and restart it. 7. If the device still doesn't get provisioned and subsequently online, try to provision it via the LAN port. 8. Connect the device to an internet cable. The device by default has DHCP enabled on it and would connect the a DHCP enabled network automatically. Post this it will automatically get provisioned and connect to the EnergyLogicIQ cloud platform. 9. Contact LogicLadder support If after trying all the above steps the device doesn t come online. 2. Network LED not blinking Please check that SIM is rightly inserted in device if YES then try following: 38

44 1. Please check whether the GSM antenna is connected with the device. 2. check the network GSM strength, there may be very poor network available at the site or antenna is not exposed. 3. Please check SIM by inserting in a mobile phone and check its functionality like network strength. 4. You can also check SIM card type may not be supported by our IoT cloud connector or block by your Supplier or not activated. We support GSM 4 pin, 6 pin or 8 pin SIM cards supporting 1.8/ Incorrect fuel level reading If you the EnergyLogicIQ cloud platform is displaying wrong levels try the following: 1. On the EnergyLogicIQ cloud platform click on the generator (for internal tank) or external Tanks 2. Check that the sensor deadband and sensor range are set correct 3. If the above two parameters are correct check if the sensor is clear of the tank side walls and obstructions. 4. There is any fixed offset (due to error in calibration or tank size is greater than sensor measurement length etc.) apply offset on platform. 5. You can re-calibrate the sensor as a last resort before contacting our support team. 4. Incorrect fuel quantity reading If the fuel level being recorded and displayed by the EnergyLogicIQ cloud platform is correct and the fuel quantity (volume) is displayed wrong it could be due to the tank dimensions being wrong or tank shape being irregular. The platform converts the fuel level into volume based on tank dimensions for regular shape tanks and these should be accurate. You can check the dimensions of internal tanks by going to the generator or specific tank dashboard. 39

45 5. Generator On/off detection issues 1. Check that the wiring to the generator PFC relay is proper and its connected on right channel on the Cloud gateway. 2.
