Despite being connected to a power source,
the fuel sensor does not receive any power

The issue will be identified during the check that the technician should perform with the electronic test tool (FLUKE).

1. Ensure that the incoming wires from the power source are properly secured at both ends. A power source can be an external source or a Galooli internal connection, such as an Elara cabinet tray/Elara metal box.

2. Ensure that the power supply is between 10 and 30 volts DC.

 When the fuel sensor is connected to the communication terminal block but is unable to communicate with the Elara device 

• Connect the fuel sensor cables to the terminal block properly.

• Ensure that the terminal block's power supply is 12 volts. 

• The RS485 connection cables should be connected according to the pinout diagram:
  

  • On the fuel sensor side

    

  • On the terminal block side - refer to the wiring diagram provided by Galooli
    

Despite receiving power and being properly connected, the Galooli gateways in Power Center are not connected to the fuel sensor

1. Ensure that the fuel sensor ID is configured with the correct baud rate of 19200 and the device ID by the wiring diagram.

   

2. Be sure to select the correct fuel sensor parameters when adding the fuel sensor to the Elara gateway, including: "Device", "ID", and "Device Baudrate” according to the wiring diagram provided by Galooli.

   

Fuel sensors are communicating properly, but the data they provide is incorrect.

1. Remove the fuel sensor from the fuel tank and place it straight on a flat surface. Ensure the tip of the fuel sensor is 2 cm away from the base of the fuel's sensor securing rod.
   

2. Read all configurations from the fuel sensor calibration tab on the “Services center”.

   

3. Once done perform the “Zero calibration” on the fuel sensor

The fuel reading is stuck

Several platforms can be used to identify the problem, including ZonMax, Web Solution, Power Center and the Mobile App.

1. Verify that the fuel reading is indeed stuck

• what to do when the fuel reading is "wave" pattern

1. by comparing the reading in the ZonMax/Web Solution platform with the reading in the Power Center platform at different times. In the event that the readings are the same, proceed to the next step.

2. Create a detailed report through one of the Galooli platforms and check when the fuel reading ceased. If you have determined the time and date at which the readings of the fuel stopped, proceed to the next step.

3. Check whether the fuel calibration table has been modified in accordance with the previous section.

4. Verify that the fuel sensor pores are not blocked at the diaphragm.

5. Make sure that there is no sludge in the fuel tank.

If the fuel reading shows a wave pattern, what should be done?

הבעיה לא ברורה, בבדיקה

• Make sure the fuel is of good quality.

• Make sure that the fuel sensor is properly secured.

• If the sensor's open-air value exceeds the OA value of +7 or -7, it may indicate a fault.

• Make sure that a calibration table has been applied.

When it is required to recalibrate the sensor?

• Following the cleaning of the fuel tank.

• Ensure that the fuel sensor is properly secured to the sensor securing rod.

• Check for signs of wear and tear.

• Three years after the start of the project

When is it necessary to perform a full calibration procedure?

• As part of the installation of a new fuel sensor.

• A fuel tank/generator has been swapped.

• The fuel tank has been cleaned.
