Smart Water Control with VEICHI Solar Drives: Float Switch and Electrode Connections

Smart Water Control with VEICHI Solar Drives

Effective water management is one of the most critical factors affecting system efficiency and equipment protection in solar-powered irrigation systems. Float switches, electrodes, and pressure switches used in wells, storage tanks, and water transfer systems play a vital role in ensuring safe and reliable pump operation.

In this episode of the System Solar Power Energy Systems technical content series, we explain the smart water control functions available in VEICHI solar drives and how float switch and electrode connections are implemented.

How Is Water Control Achieved in VEICHI Solar Drives?

Through the digital input terminals available on VEICHI solar drives, float switches, electrodes, and pressure switches can be directly integrated into the control system.

This allows users to:

* Start the motor according to water level conditions,

* Stop the motor according to water level conditions,

* Protect water wells from dry-running,

* Prevent storage tank overflow,

* Create automatic start-stop control scenarios.

The operating logic can be customized according to the specific needs of each application.

Which Terminals Are Used for Float Switch and Electrode Connections?

For standard start-stop control applications, the X1 and COM terminals can be used.

For float switch and electrode applications, X3, X4, and COM terminals are typically utilized.

This structure allows the drive to continuously monitor water levels and activate protection functions whenever necessary.

Advantages of Delay Timer Functions

One of the key advantages of VEICHI solar drives is the ability to assign delay times to float switch and electrode inputs.

For example:

* Stopping the motor after a predefined delay when the water level drops,

* Restarting the motor after a specified delay once the well is refilled,

* Preventing unwanted operation caused by sudden water level fluctuations.

Delay times can be adjusted from a few seconds to several minutes depending on the application requirements.

These functions are particularly beneficial in wells, storage tanks, and water systems where water levels change rapidly.

What Is A-Ful Protection?

When the water level drops below the predefined threshold or when the electrode circuit becomes open, the drive automatically enters protection mode.

The A-Ful indication displayed on the drive screen confirms that the water protection function has been activated.

Once the water level returns to the desired level and the configured delay period expires, the drive can automatically resume operation.

This feature protects both the motor and pump system against dry-running conditions and contributes to longer equipment life.

Flexibility with Three-Electrode Applications

VEICHI solar drives also support three-electrode water level monitoring systems.

Lower-level, middle-level, and upper-level control points can be defined to achieve more precise water management.

Similarly, three-wire float switch systems can be configured using common and position terminals to create different operating scenarios.

This flexibility enables safer and more efficient operation based on specific field requirements.

Conclusion

Float switches, electrodes, and pressure switches are essential components of modern irrigation automation systems.

With advanced digital input architecture and programmable delay functions, VEICHI solar drives provide reliable water level management while improving system efficiency and equipment protection.
