6. Setup and Installation

Follow these steps for proper installation of the water level controller:

1. Mounting: Secure the controller using the M3 screw holes to a stable surface near the water tank or area to be monitored. Ensure it is protected from direct water splashes.
2. Power Connection: Connect the AC/DC 12V power supply to the terminals labeled "AC/DC12V" on the board. Observe polarity if using DC power.
3. Sensor Connection: Connect the water level sensors (not included) to the designated terminals. Typically, there are three connections:
   • Common (GND): Connect to the lowest point or bottom of the tank.
   • Lower Water Level (下水位): Connect to the sensor placed at the desired minimum water level.
   • Upper Water Level (上水位): Connect to the sensor placed at the desired maximum water level.
4. Output Connection: Connect the device to be controlled (e.g., water pump, solenoid valve) to the "输出" (Output) relay terminals. This is a dry contact relay, meaning it provides a switch closure. Ensure the connected device's power requirements are within the 10A output capacity.
5. Testing: After all connections are made, apply power and test the system by manually simulating water level changes to ensure the relay activates and deactivates as expected.

7. Operating Instructions

The FTVOGUE XHM203 operates automatically based on the water levels detected by its sensors. Once properly installed and powered, the controller will manage the connected device (e.g., pump) as follows:

• Water Filling Mode: If the controller is configured to fill a tank, the relay will activate (e.g., turn on a pump) when the water level drops below the "Lower Water Level" sensor. The relay will deactivate (e.g., turn off the pump) when the water level reaches the "Upper Water Level" sensor.
• Water Draining Mode: If the controller is configured to drain a tank, the relay will activate (e.g., turn on a pump) when the water level rises above the "Upper Water Level" sensor. The relay will deactivate (e.g., turn off the pump) when the water level drops below the "Lower Water Level" sensor.

The specific mode (filling or draining) depends on how the output relay is wired to your pump or valve. Consult the wiring diagram for your specific application.

8. Maintenance

Regular maintenance ensures optimal performance and longevity of your water level controller:

• Visual Inspection: Periodically inspect the controller and all connections for any signs of damage, corrosion, or loose wiring.
• Sensor Cleaning: If using conductive probes, ensure they are clean and free from mineral buildup or debris, which can affect their accuracy.
• Environmental Check: Ensure the controller remains in a dry, protected environment, free from excessive dust or moisture.
• Power Cycle: If the device exhibits unusual behavior, try disconnecting and reconnecting the power supply.
