6. Schemat połączeń

Refer to the wiring diagram below and the provided owner's manual for correct electrical connections. Ensure all connections are secure and insulated to prevent short circuits.

• Czerwony przewód: Connect to +9-32V DC power supply.
• Czarny przewód: Connect to Ground (-).
• Niebieski przewód: Connect to Tachometer Signal Input. This signal can be sourced from the engine's ignition coil, crankshaft sensor, or a dedicated tacho sensor (sold separately, e.g., ASIN B07RN3HJ72 or B07RR8NQ45).
• Pomarańczowy przewód: Connect to Backlight (+).

The tachometer is suitable for both diesel and gasoline engines. The signal input method may vary depending on your engine type.

7. Działanie

7.1. Speed Ratio Adjustment

The tachometer requires a speed ratio setting to accurately display RPM. This ratio is adjustable from 1 to 300. The default idle speed is typically 600-800 RPM.

1. Wejdź w tryb konfiguracji: Press and hold the back button located on the rear of the tachometer for 3 seconds. The display will show the current speed ratio setting.
2. Adjust Ratio: While in setup mode, press the button repeatedly to increase the ratio value. The value will increment by 0.5 with each press.
3. Zapisz ustawienia: Once the desired ratio is displayed, release the button for 3 seconds. The tachometer will automatically save the new setting and exit setup mode.

Notatka: If your tachometer signal is derived from the flywheel, the ratio value should correspond to the number of engine gear teeth divided by two (Poles/2). If the signal comes from the ignition coil in a gasoline engine, the ratio should be set to the number of cylinders divided by two (Cylinder/2).

7.2. Hour Meter Function

The tachometer includes an integrated hour meter that continuously records the total operating hours of the engine. This hour meter cannot be reset.

8. Rozwiązywanie Problemów

If you encounter issues with your tachometer, consider the following general troubleshooting steps:

• Brak zasilania/wyświetlacza: Check all power connections (Red wire to +V, Black wire to Ground). Ensure the operating voltage mieści się w zakresie 9-32 V DC.
• Incorrect RPM Reading: Verify the speed ratio setting. Adjust it as described in Section 7.1. Ensure the signal input (Blue wire) is correctly connected to a reliable RPM signal source (ignition coil, crankshaft sensor, or tacho sensor).
• No RPM Movement: Confirm the signal wire is properly connected and receiving a signal. If using a tacho sensor, ensure it is functioning correctly.
• Odczyty przerywane: Check for loose or corroded connections. Ensure the signal wire is not experiencing interference.

For persistent issues, consult a qualified technician or contact ELING customer support.
