WALFRONT 0-10V Adjustable Signal Generator Instruction Manual

1. Introduction

This manual provides instructions for the safe and effective operation of the WALFRONT 0-10V Adjustable Signal Generator. This device is designed to provide a stable 0-10V voltage signal output for various industrial and testing applications.

2. Product Features

• 0-10V Analog Output: Features one analog output channel capable of generating a 0-10V voltage signal.
• Display Calibration: Equipped with potentiometers on the back for precise voltage display calibration.
• Robust Protection: Includes overcurrent protection, reverse connection protection, and a protective back cover to resist dusty environments.
• Clear Display: A 4-digit digital tube display with high brightness, offering three switchable display modes: Voltage, Percentage, and Hz.
• Adjustable Output: A rotation encoder allows for fine and coarse tuning of the output signal.
• Easy Wiring: Designed with large terminals for straightforward and secure connections.

3. Specifications

4. Setup and Wiring

Before connecting the signal generator, ensure the power supply is off. Connect the device according to the wiring diagram below. The large terminals facilitate easy and secure connections.

Figure 4.1: Wiring schematic diagram for connecting the signal generator to voltage signal acquisition equipment. Connect V+ and V- to the 24V power supply, and OUT+ and OUT- to AV+ and AV- of the acquisition equipment, respectively.

Power Supply: The device requires a 15-30V DC power supply. Ensure correct polarity as the device includes anti-reverse connection protection.

Output Connection: Connect the output terminals (OUT+ and OUT-) to your target device or system that requires a 0-10V analog input.

5. Operating Instructions

Once properly wired and powered on, the signal generator's 4-digit digital tube display will illuminate.

5.1 Adjusting Output Voltage

Figure 5.1: Front view of the signal generator showing the digital display and the rotary encoder for output adjustment.

• Rotary Encoder: Use the rotary encoder knob on the front panel to adjust the output voltage. Turning the knob clockwise increases the voltage, and counter-clockwise decreases it.
• Coarse and Fine Tuning: The encoder provides both coarse and fine tuning capabilities. A single turn of the encoder corresponds to 20 pulses, allowing for precise adjustments.
• Saving Output Value: Press the rotary encoder knob to save the current output value. This ensures the device retains the setting even after power cycling.

5.2 Display Modes

The digital display can switch between three modes:

• Voltage (V): Displays the current output voltage in Volts.
• Percentage (%): Displays the output as a percentage of the full 10V scale.
• Frequency (Hz): (Note: While the product title mentions "Frequency Control Meter", the specifications and description primarily focus on voltage output. This mode might display a related frequency if applicable, or it might be a general display option for other models. For this 0-10V model, the voltage and percentage modes are most relevant.)

Refer to the device's specific button or knob press sequence (if any, not detailed in provided info) to cycle through these display modes.

5.3 Display Calibration

Figure 5.2: The signal generator's output being measured by a multimeter, showing a stable 10.00V reading, demonstrating accuracy.

If the displayed voltage value deviates from the actual output, you can calibrate it:

1. Connect a precise voltmeter or multimeter to the output terminals (OUT+ and OUT-).
2. Locate the voltage display calibration potentiometers on the back of the module.
3. Adjust these potentiometers carefully until the value displayed on the signal generator matches the reading on your external voltmeter.

6. Applications

The WALFRONT 0-10V Adjustable Signal Generator is suitable for a variety of industrial and testing scenarios:
