Q-BAIHE XDL-HS380 Three-Phase Sinusoidal Signal Generator

1. Introduction

This manual provides detailed instructions for the Q-BAIHE XDL-HS380 Three-Phase Sinusoidal Signal Generator. This device is designed to produce three-phase sinusoidal signals with adjustable frequency and phase, suitable for various electrical testing and simulation applications. Please read this manual thoroughly before operating the device to ensure proper use and safety.

2. Safety Information

Always observe the following safety precautions to prevent injury or damage to the device:

• Ensure the power supply voltage is within the specified range (7-12VDC).
• Do not expose the device to moisture or extreme temperatures.
• Avoid short-circuiting the output terminals.
• Disconnect power before making any wiring changes.
• Handle the module with care to prevent damage to electronic components.

3. Product Overview

The Q-BAIHE XDL-HS380 is a compact module consisting of a main control board and an LCD display. It features user-friendly buttons for parameter adjustment and a clear display for monitoring settings.

4. Setup

Follow these steps to set up your signal generator:

1. Connect the LCD Display: Carefully align and connect the LCD display module to the pin headers on the main control board.
2. Power Wiring (P1): Connect the power supply to the P1 terminal block.
   • VDD: Connect to the positive terminal of your 7-12VDC power supply.
   • GND: Connect to the negative terminal of your power supply.
3. Signal Output Wiring (P2): Connect your load or measurement equipment to the P2 terminal block.
   • Q3C: Phase C signal output.
   • Q2B: Phase B signal output.
   • Q1A: Phase A signal output.
4. Initial Power On: Once all connections are secure, apply power. The LCD display should illuminate and show the current settings.

5. Operating Instructions

The device features several buttons for adjusting parameters:

• FUN: Function button. Use this to cycle through adjustable parameters (e.g., frequency, phase). A long press on the "FUN" button will save the currently set values, which will be recalled upon the next power-on.
• UP/DOWN: Adjusts the selected parameter's value incrementally.
• ADD/SUB: Adjusts the selected parameter's value in larger steps or changes the digit being adjusted.

Parameter Adjustment:

1. Press the FUN button to select the parameter you wish to adjust (e.g., frequency, phase). The selected parameter will typically blink or be highlighted on the LCD.
2. Use the UP and DOWN buttons for fine adjustments.
3. Use the ADD and SUB buttons for coarse adjustments or to move between digits for faster input.
4. Once the desired value is set, press and hold the FUN button to save the settings.

Signal Type Selection: The device may allow selection between Sine wave and PWM (Pulse Width Modulation) signals. Refer to the on-screen prompts or specific button combinations for this functionality. The amplitude value can be adjusted within narrow limits via the PWM pulse width.

6. Maintenance

The Q-BAIHE XDL-HS380 is a low-maintenance device. To ensure its longevity and proper operation:

• Keep the device clean and free from dust. Use a soft, dry cloth for cleaning.
• Store the device in a dry environment, away from direct sunlight and extreme temperatures.
• Avoid physical shock or excessive vibration.

7. Troubleshooting

If you encounter issues with your signal generator, consider the following:

• No Power/Display Off:
  • Check power supply connections (VDD, GND) and ensure the voltage is within 7-12VDC.
  • Verify the power supply is functioning correctly.
  • Ensure the LCD display is securely connected to the main board.
• Incorrect Output Signal:
  • Verify the frequency and phase settings on the display.
  • Check output wiring (Q1A, Q2B, Q3C) for correct connections.
  • Note that the output may exhibit a D-A quantizing waveform. This is normal for digital-to-analog conversion and can typically be filtered out by external circuitry if a smoother signal is required.
  • The output impedance is relatively high. Consider using a buffer or amplifier if driving low-impedance loads.
• Parameters Not Saving:
  • Ensure you perform a long press on the "FUN" button after setting parameters to save them.
