4. Konfigurazzjoni u Installazzjoni

Follow these steps for proper installation of your tachometer gauge. Ensure the vehicle's power is disconnected before beginning installation.

4.1 Immuntar tal-Gauge

1. Agħżel post adattat fuq id-dashboard jew il-pannell tiegħek għall-installazzjoni.
2. Cut a circular hole with an approximate diameter of 52mm (2 inches) at the chosen location.
3. Insert the tachometer gauge into the hole.
4. Waħħal il-gauge minn wara billi tuża l-bracket tal-immuntar u l-ġewż provduti.

4.2 Konnessjonijiet tal-Wiring

Refer to the wiring diagram below and the provided connecting cable for correct connections. Incorrect wiring can damage the device or vehicle electrical system.

• Wajer Aħmar: Connect to Battery Positive (+9-32V DC).
• Wajer Blu: Connect to Battery Negative (-).
• Wajer Iswed: Connect to Signal Input. This receives the pulse signal from your tacho sensor, engine, alternator, ignition coil, or crankshaft sensor.
• Orange/Yellow Wire: Connect to Backlight Positive (+9-32V DC). This powers the red backlight.

After all connections are made, ensure they are secure and insulated to prevent short circuits. Reconnect the vehicle's power.

5. Istruzzjonijiet Operattivi

The Keenso Digital Tachometer Gauge provides real-time engine RPM and accumulated operating hours on its LCD display.

Immaġni 5.1: Mill-qrib view of the digital display, clearly showing RPM (Revolutions Per Minute) and accumulated operating hours (H).

5.1 Qari tad-Displej

• The large digital numbers indicate the engine's RPM (Revolutions Per Minute), typically displayed as "RPM x10" or similar, meaning the displayed value should be multiplied by 10. The indicating range is 0-9990 RPM.
• The smaller digital numbers, usually accompanied by an "H", display the total accumulated operating hours of the engine.

5.2 Power On/Off

The gauge will power on automatically when connected to a 9-32V DC power source and will display readings once an engine pulse signal is detected. It powers off when the power source is disconnected.

6. Manutenzjoni

The Keenso Digital Tachometer Gauge is designed for durability and requires minimal maintenance.

• Tindif: Wipe the display and bezel with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the surface or anti-fog coating.
• Reżistenza għall-Ilma: The gauge has an IP67 rating, meaning it is protected against dust and can withstand immersion in water up to 1 meter for 30 minutes. However, prolonged submersion or high-pressure water jets should be avoided.
• Konnessjonijiet: Periodically check wiring connections to ensure they remain secure and free from corrosion.

7 Issolvi l-problemi

If you encounter issues with your tachometer gauge, refer to the following common problems and solutions:

• Ebda Wiri/Ebda Qawwa:
  • Check the power connections (Red wire to positive, Blue wire to negative) for proper voltage (9-32V DC) and secure contact.
  • Ensure the backlight wire (Orange/Yellow) is correctly connected if the backlight is not illuminating.
• Incorrect RPM Reading:
  • Verify the signal wire (Black) is correctly connected to a reliable pulse signal source (tacho sensor, ignition coil, alternator, crankshaft sensor).
  • Ensure the signal source is functioning correctly.
  • Check for any loose or corroded connections in the signal line.
• Display Flickering or Intermittent:
  • Check all wiring for loose connections or damaged insulation.
  • Ensure the power supply is stable and within the 9-32V DC operating range.
