4. Kurulum ve Kurulum

Proper installation and adjustment are crucial for accurate fuel level readings. Follow these steps carefully:

4.1. Kurulum Öncesi Adımlar

1. Measure Tank Depth: Accurately measure the depth of your fuel tank from the mounting surface to the bottom. The sender is adjustable for tanks between 6-3/4 inches (17.1 cm) and 23 inches (58.4 cm).
2. Adjust Float Arm: The float arm must be adjusted to match your tank's depth. The arm can be carefully bent to ensure the float reaches the bottom of the tank when empty and the top when full, without hitting the tank walls or bottom. Ensure the float has full range of motion.
3. Montaj Yüzeyini Hazırlayın: Clean the fuel tank's mounting surface thoroughly, removing any debris, old gasket material, or corrosion.

4.2. Kurulum Prosedürü

1. Contayı takın: Place the new mounting gasket onto the fuel tank's mounting flange.
2. Insert Sender: Carefully insert the VDO ALAS fuel sender into the tank opening, ensuring the float arm and float are positioned correctly and can move freely.
3. Güvenli Montaj Plakası: Align the sender's mounting plate with the bolt holes on the tank flange. Secure the sender using appropriate fasteners (not included) and tighten them evenly to create a leak-proof seal. Do not overtighten.
4. Elektrik Bağlantıları:
   • Connect the sender's signal wire to the fuel gauge's input terminal.
   • Connect the sender's ground wire to a reliable chassis or battery ground point. Ensure a clean, secure connection for accurate readings.
5. Pili Yeniden Bağlayın: Once all connections are secure and verified, reconnect the vehicle's or vessel's battery.

5. Kullanım Talimatları

The VDO ALAS Adjustable Fuel Sender operates by varying its electrical resistance based on the fuel level. As the fuel level changes, the float moves the arm, which in turn changes the resistance of the sender unit. This resistance change is then interpreted by a compatible fuel gauge, which displays the current fuel level.

• Uyumluluk: Ensure your fuel gauge is designed to work with a 10-184 Ohm input sender for accurate readings.
• İlk Kontrol: After installation, fill the fuel tank and observe the gauge reading. Then, if possible, drain the tank to verify the empty reading. This helps confirm proper installation and adjustment.
• Normal Çalışma: The sender will continuously provide fuel level data to the gauge as long as the system is powered.

6. Bakım

The VDO ALAS Adjustable Fuel Sender is designed for long-term reliability with minimal maintenance. However, periodic inspection can help ensure continued accurate performance:

• Görsel Muayene: Annually inspect the sender unit, float arm, and electrical connections for signs of corrosion, damage, or wear.
• Float Arm Movement: Ensure the float arm moves freely without any obstruction or binding.
• Elektrik Bağlantıları: Check that all electrical connections are clean, tight, and free from corrosion. Loose or corroded connections can lead to inaccurate readings.
• Conta Bütünlüğü: Inspect the mounting gasket for any signs of cracking, drying, or leaks. Replace if necessary.
