4. Setup and Installation

Careful installation is crucial for accurate and reliable operation. Please follow these steps:

4.1 Wiring Diagram

Figure 4.1: Wiring connections for the tachometer and Hall sensor.

This diagram illustrates the wiring connections. The tachometer module has terminals for AC 110V~230V input (labeled AC IN) and a 3-pin connector for the NPN Hall Sensor. The Hall sensor wires are typically Black, Orange, and Blue, connecting to the corresponding pins on the module.

1. Power Connection: Connect the AC 110V-230V power supply to the designated AC input terminals on the tachometer module. Ensure proper voltage matching for your region.
2. Hall Sensor Connection: Connect the Hall proximity switch sensor to the 3-pin connector on the tachometer module. Typically, the wires are:
   • Black wire: Ground
   • Orange wire: Signal output
   • Blue wire: Power supply for sensor
   Refer to the wiring diagram (Figure 4.1) for precise connections.

4.2 Sensor and Magnet Placement

Figure 4.2: Example of Hall sensor and magnet placement on a rotating shaft.

This image shows the Hall sensor mounted near a rotating shaft, with a small magnet attached to the shaft. The sensor detects the magnet's passage to count rotations. The display unit is shown indicating an RPM value.

1. Magnet Attachment: Securely attach the provided magnet to the rotating part whose RPM you wish to measure.
   • Important: The magnet cannot be installed on metal material, as this will interfere with detection.
   • Important: Pay attention to the front and back when installing the magnet to ensure proper detection by the sensor.
2. Sensor Mounting: Mount the Hall proximity switch sensor in a fixed position such that its sensing face is aligned with the path of the magnet.
   • The distance between the Hall switch and the magnet must be within 10mm for reliable detection.
   • Ensure the sensor and magnet are securely fixed during testing to prevent vibration, which can cause unstable or inaccurate readings.

This image provides a close-up view of the Hall sensor and the magnet, emphasizing the critical distance requirement for accurate detection. Text overlays highlight key installation notes, including avoiding strong electromagnetic interference and ensuring secure fixation.

5. Operation

Once the tachometer and sensor are correctly installed and wired, operating the device is straightforward.

1. Power On: Apply AC 110V-230V power to the tachometer module. The LED display will illuminate.
2. Start Rotation: Begin the rotation of the machinery or component being measured.
3. Read RPM: The 4-bit LED display will show the current RPM value.
4. Over-Range Indication:
   • If the rotation speed is too low (below 10 RPM), the display will show "LLLL".
   • If the rotation speed is too high (above 9999 RPM), the display will show "HHHH".

Figure 5.1: Tachometer display indicating low ("LLLL") and high ("HHHH") RPM conditions.

This image shows the digital LED display of the tachometer. One display shows "LLLL", indicating that the detected RPM is below the measurable range. Another display shows "HHHH", indicating that the detected RPM is above the measurable range.

6. Maintenance

The Icstation Digital LED Tachometer is designed for durability and requires minimal maintenance. Follow these guidelines to ensure long-term performance:

• Cleaning: Keep the display unit and sensor free from dust and debris. Use a soft, dry cloth for cleaning. Avoid abrasive cleaners or solvents.
• Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion.
• Sensor and Magnet Alignment: Verify that the Hall sensor and magnet remain securely fixed and properly aligned. Vibrations or shifts can affect accuracy.
• Environmental Conditions: Operate the device within its specified environmental conditions. Avoid extreme temperatures, humidity, or direct exposure to water.
