Automatic Backwashing Filter Operation Instructions
1.Description
This controller is specially designed for multi-element automatic backwash filter t, and can be matched with various working conditions and control processes of automatic cleaning filter equipment, with the advantages of low cost, high efficiency, and high reliability.
The controller adopts the current mainstream high-speed CPU chip with a 5-inch full-color touch screen display, which has the characteristics of intuitive display, simple operation, and high degree of visualization. It has a variety of protection and alarm mechanisms, has a pressure sensing function, and the working mode supports time and pressure difference to start cleaning.
2. Input/Output and Power Specifications

3. Control Processes
- Filtration stage: the motor stops, the drain valve is closed to enter the filtration state and timed.
- Backwash start: When the filter setting time is up or the pressure difference switch detects a continuous pressure difference signal, backwash cleaning will start after the pressure difference delay time.
- Backwash Cleaning stage: the motor starts, after the filter element is detected, open the drain valve to enter the cleaning time. When the cleaning time is up, the next filter element will be detected. After all the filter elements are cleaned, the cleaning cycle is complete. And it will enters into the filtration stage again.
- Alarm trigger:
- Pressure difference delay alarm which meets the condition of the differential pressure switch signal.
- The inlet and outlet water pressure reaches the upper and lower limit alarm conditions.
- The inlet water pressure is lower than the outlet water pressure.
- Any one of the above three conditions will trigger an alarm.
