2. Safety Information

• Ensure the power supply matches the module's voltage requirements (12V DC).
• Disconnect power before making any connections or performing maintenance.
• Avoid exposing the module to moisture, extreme temperatures, or corrosive environments.
• Installation should be performed by qualified personnel if you are unfamiliar with electrical wiring.
• Do not exceed the relay's maximum switching capacity (10A at 250VAC / 10A at 30VDC).

3. Product Features

The FTVOGUE 12V Level Control Switch Module offers reliable liquid level detection and control with the following features:

• Durable Construction: Made with a high-quality PCB board for low power consumption and extended lifespan.
• Stable Performance: Features simple wiring, low power consumption, and high switching capacity for consistent operation.
• Easy Installation: Compact and lightweight design allows for convenient setup.
• Wide Application: Suitable for use in various environments requiring automatic drainage or liquid level management, such as pond tanks, garages, and basements.

4. Component Identification

Familiarize yourself with the key components and terminals of the module:

• VCC: Power input (12V DC).
• GND: Ground connection.
• HIGH: Input for the upper liquid level sensor.
• LOW: Input for the lower liquid level sensor.
• COM (Sensor): Common connection for liquid level sensors.
• NO: Relay Normally Open contact.
• NC: Relay Normally Closed contact.
• COM (Relay): Common contact for the relay output.

5. Setup and Installation

Follow these steps to install your level control switch module:

1. Mounting: Securely mount the module in a dry, stable location away from direct moisture or excessive vibration.
2. Power Connection: Connect a 12V DC power supply to the VCC and GND terminals. Ensure correct polarity.
3. Sensor Connection: Connect your liquid level sensors to the HIGH, LOW, and COM (Sensor) terminals. The HIGH terminal is for the upper level sensor, and the LOW terminal is for the lower level sensor. The COM (Sensor) terminal is the common connection for both sensors.
4. Load Connection: Connect the device you wish to control (e.g., pump, valve) to the relay output terminals: NO, NC, and COM (Relay). Choose between NO (Normally Open) or NC (Normally Closed) based on whether you want the device to activate when the relay is energized or de-energized.
5. Verify Connections: Double-check all wiring for correctness and secure connections before applying power.

6. Operating Instructions

Once properly installed and powered, the module operates as follows:

• The module continuously monitors the liquid levels via the connected sensors.
• When the liquid level reaches the HIGH sensor, the relay will activate (or de-activate, depending on configuration) to control the connected load.
• When the liquid level drops below the LOW sensor, the relay will switch back to its original state, controlling the connected load accordingly.
• This allows for automatic control of pumps (e.g., for drainage or filling) or alarms based on predefined liquid levels.

7. Maintenance

The FTVOGUE Level Control Switch Module is designed for long-term, low-maintenance operation. To ensure optimal performance:

• Periodically inspect all wiring connections to ensure they remain secure.
• Keep the module clean and free from dust and debris. Use a soft, dry cloth for cleaning.
• Ensure the operating environment remains within the specified temperature and humidity ranges.
• Regularly check the liquid level sensors for any buildup or damage that might affect their accuracy.
