This advanced system combines a digital water level controller and a 3-phase DOL motor control panel, offering reliable protection and control for your pump motors. Here are the key features:

1. Microcontroller-Based System:

   • Digital Water Level Control: Automatically manages water levels in both overhead and underground tanks.
   • Digital Volt and Amp Meters: Monitors system voltage and load current for precise tracking of motor performance.

2. Protection Features:

   • Overload Protection: Adjustable overload protection (0 to 30 A) to prevent damage from excessive current.
   • High & Low Voltage Protection: Customizable voltage limits to protect the motor from voltage fluctuations.
   • Short Circuit Protection: Safeguards the motor from short circuit risks.
   • Dry Run Protection: Detects if the motor is running without water, stopping the motor to prevent damage, with adjustable dry run current settings (0 to 30 A).
   • Cyclic and Delay Timers: Adjustable timers (0 to 999 minutes) for controlling motor operation, with bypass facilities for both.

3. Auto-Switch & Reset Functionality:

   • Auto Switch with Bypass: Automatically starts the system when power is restored, with an adjustable auto-switch timer.
   • Error Message Display: Displays error codes for troubleshooting.
   • Factory Reset: Resets to factory settings if incorrect values are entered.

4. SPP (Phase Protection):

   • Phase Failure Protection: Prevents motor damage from phase loss or phase interchange in 3-phase systems, protecting against motor winding burnouts.
   • Voltage Difference Protection: Ensures that the voltage between the three phases remains balanced to prevent motor damage.

5. User-Friendly Interface:

   • Motor Start/Stop Buttons: Provides manual control to start and stop the motor.
   • Set Button: Allows easy adjustment of current, voltage, and timer settings.
   • Reset Button: Quickly resets the unit to clear errors.
   • Indications: Visual indicators for motor operation, voltage/amp monitoring, auto bypass status, and water levels.

6. Build Quality:

   • Durable ABS Enclosure: Ensures long-lasting and safe operation in various environmental conditions.

7. Suitable for Motors Up to 10 HP: Ideal for managing motors up to 10 horsepower in water pumping systems.

This system is designed to enhance motor safety, improve system efficiency, and protect your valuable equipment from electrical and mechanical failures.
