Figure 8: Detailed Wiring and Technical Parameters for Sensors

Two-Wire System (e.g., Magnetoelectric Sensor for Diesel Engine)

• Instalacja: The sensor is mounted on the engine's flywheel casing, positioned vertically to the top surface of the flywheel gear. The distance (L) between the induction end of the sensor and the flywheel top surface should be ≤1mm. A smaller distance results in a stronger output signal.
• Połączenie przewodowe: Both wires are typically black. One connects to the signal output, and the other to Ground (GND). There is no specific direction requirement for the wire connection.
• Parametry techniczne:
  • Objętość wyjściowatage: Sinusoidal wave
  • Measurement range: 100-15000Hz
  • Efektywna objtage (at 360Hz): ≥1.5VAC (multimeter), peak voltage ≥5V (oscilloscope)
  • Resistance (at 25℃): 1200Ω±10%
  • Gear modules: ≥2
  • Stopień ochrony: IP65
  • Length: L=100MM L1=80MM

Three-Wire System (e.g., Holzer Sensor for Inboard or Gas Engine)

• Instalacja: The sensor is mounted on the engine's flywheel casing, positioned vertically to the top surface of the flywheel gear. The distance (L) between the induction end of the sensor and the flywheel top surface should be ≤2mm.
• Połączenie przewodowe:
  • Red wire: Connect to Vcc (+) (18-32V)
  • Blue wire: Connect to Vss (-)
  • Black wire: Connect to signal output
• Parametry techniczne:
  • Objętość pracytage: 18-32V
  • Objętość wyjściowatage: Rectangular wave
  • High level: >10V
  • Low level: <0.7V
  • Duty ratio: 50±20%
  • Frequency: ≤20KHz
  • Stopień ochrony: IP65
  • Length: L=80MM L1=70 / L=80MM L1=60MM

7. Działanie

The tachometer features a single black button on the backside for configuration.

Speed Ratio Adjustment

The speed ratio (pulse per revolution) needs to be set according to your engine's specifications for accurate RPM readings. The adjustable range is 1-360.

1. Wejdź w tryb ustawień: Long press the black button on the backside of the tachometer for 3 seconds. The display will show the current speed ratio.
2. Adjust Speed Ratio:
   • While in setting mode, long press the black button again to increase the speed ratio value.
   • Release the button, then long press it again to decrease the speed ratio value.
3. Zapisz ustawienia: Once the desired speed ratio is displayed, release the button. The tachometer will automatically save the new setting after 3 seconds. If the setting is not satisfactory, repeat the process.
4. Wyjście z trybu ustawień: Release the black button for more than 3 seconds to exit the setting mode.

Zmiana koloru podświetlenia

The tachometer offers 7 backlight colors. To change the backlight color:

• Krótkie naciśnięcie: Short press the black button (less than 3 seconds) to cycle through the backlight colors in the following sequence: Red → Green → Blue → White → Yellow → Cyan → Purple.
• Cykl automatyczny: After Purple, the next short press will activate the automatic cycle mode, where the backlight color switches every 1 minute.

9. Rozwiązywanie Problemów

If you encounter issues with your tachometer, consider the following common problems and solutions:

• Brak zasilania/wyświetlacza:
  • Check the Red (+) and Black (-) power connections for proper voltage (9-32VDC) and secure contact.
  • Ensure the fuse in the power line (if installed) is not blown.
• Incorrect RPM Reading:
  • Verify that the speed ratio is correctly set according to your engine's specifications (refer to Section 7).
  • Check the Blue (RPM Signal) wire connection to the sensor and ensure the sensor is properly installed and functioning.
  • For two-wire sensors, ensure the distance between the sensor and flywheel gear is ≤1mm. For three-wire sensors, ensure the distance is ≤2mm.
  • Inspect the sensor and wiring for any damage or corrosion.
• Podświetlenie nie działa/zmienia się:
  • Check the Yellow (Backlight +) wire connection.
  • Upewnij się, że napięcie zasilania mieści się w określonym zakresietagZakres.
  • Try short pressing the black button multiple times to cycle through colors and automatic mode.
• Hour Meter Not Advancing:
  • Ensure the tachometer is receiving a valid RPM signal, as the hour meter typically relies on engine operation.
