4.3 Laidų prijungimo instrukcijos

The sending unit has two wires: a red wire for positive connection and a blue wire for negative connection. Connect these to your fuel gauge and power source as follows:

Prijunkite raudona viela from the sending unit to the teigiamas (+) terminalas of your power supply (e.g., battery positive).
Prijunkite mėlyna viela from the sending unit to the neigiamas (-) gnybtas of your power supply (e.g., battery negative).
Connect the sender signal wire (typically black or yellow on the gauge) to the signal output of the sending unit.
Įsitikinkite, kad visos jungtys yra saugios ir tinkamai izoliuotos.

5. Operacija

Once installed and wired, the fuel sending unit will transmit the fuel level to your compatible 240-33ohm fuel gauge. The gauge will display the current fuel level (Empty to Full).

5.1 Fuel Gauge Compatibility and Setting

This sending unit outputs a signal of 240 ohms when empty and 33 ohms when full. For accurate readings, your fuel gauge must be set to match this 240-33ohm standard. Refer to your fuel gauge's manual for specific instructions on how to adjust its settings.

6. Priežiūra

The Geloo Fuel Sending Unit is designed for minimal maintenance due to its durable stainless steel construction. However, periodic checks can help ensure continued accuracy and longevity.

Kasmetinė apžiūra: Annually inspect the sending unit for any signs of corrosion, damage, or loose connections.
Valymas: If accessible, gently clean any debris or buildup around the float mechanism. Avoid using harsh chemicals that could damage the NBR floats.
Laidų patikrinimas: Ensure all wiring connections remain tight and free from fraying or damage.

7. Problemų sprendimas

If you experience issues with your fuel sending unit, refer to the following common problems and solutions:

Problema	Galima priežastis	Sprendimas
Inaccurate Fuel Reading	Incorrect fuel gauge setting (not 240-33ohm). Atsilaisvinusios arba korozijos pažeistos laidų jungtys. Float mechanism obstructed or damaged. Incorrect sender length for tank depth.	Adjust fuel gauge to 240-33ohm setting (refer to gauge manual and calibration video). Patikrinkite ir pritvirtinkite visas elektros jungtis. Inspect the float for free movement and damage. Verify sender length matches tank depth.
No Fuel Reading	No power to the gauge or sender. Broken wire or faulty connection. Faulty sending unit or gauge.	Check power supply to both gauge and sender. Patikrinkite visus laidus, ar nėra nutrūkimų ar trumpųjų jungimų. Jei įmanoma, išbandykite komponentus atskirai.
Fuel Gauge Jumps/Fluctuates	Laisvas įžeminimo jungtis. Elektros trukdžiai.	Ensure a solid ground connection for both sender and gauge. Check for proper shielding of signal wires if interference is suspected.
