Power Troubleshooting

What is the fault and how can it be detected?

Troubleshooting Steps









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.

What is the fault and how can it be detected?

Troubleshooting Steps

 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

What is the fault and how can it be detected?

Troubleshooting Steps






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

Fuel Readings Troubleshooting













The fuel reading is stuck

Several platforms can be used to identify the problem

, including ZonMax, Web Solution, Power Center and the

:

  • ZonMax Live DIspaly.

  • ZonMax&Pro solution detailed report.

  • Power Center.

  • Galooli Mobile App.

Verify

In order to confirm that the fuel reading is indeed stuck

by comparing the reading in the ZonMax/Web Solution platform with the reading in the Power Center platform at different times

, follow these steps:

  1. Find a day when the generator was certainly in use. Generate a detailed report on that day using the ZonMax/Pro solution, containing two fields: "Generator X Total used" and "Generator_X.Engine_Hours". In the event that the

readings are the same,

  1. working hours of the generator change and the fuel consumption does not change accordingly, then the reading is indeed stuck and you should proceed to the next step.

Create a detailed report through

  1. Using one of the Galooli platforms, create a detailed report and

check

  1. determine when the fuel reading

ceased

  1. last changed . If you have determined the time and date at which the readings of the fuel stopped, proceed to the next step.

  2. Check whether the fuel calibration table has been modified in accordance with the previous section and make sure that a calibration table has been applied properly.

  3. Check via the Power Center if the sensor's open-air value exceeds the OA value of +7 or -7, it may indicate a fault.

  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

    1. Create a detailed report using one of the Galooli platforms in order to determine when the fuel readings begin to behave in a wave pattern. Proceed to the next step if you have determined the time and date.

    2. Check whether the fuel calibration table has been modified in accordance with the previous section and make sure that a calibration table has been applied properly.

    3. Check via the Power Center if the sensor's open-air value exceeds the OA value of +7 or -7, it may indicate a fault.
