Water level detection control board development
The following is a summary of the main features of this product:
1: The power switch of this machine is designed as three selected gear positions: manual, normally closed, automatic.
2: Internal use of 30A high-performance relay, the theory can control 2.2KW pump, it is recommended to control the pump below 1.6KW.
3: Simple installation and excellent performance.
4: Adopt intelligent circuit, reasonable design, safe and reliable, long service life, using stainless steel as detection sensor (induction voltage is 10 volts DC low voltage, human body safety voltage 36 volts)
5: The special “Hand” button and “Stop” button let you switch your pump at any time and turn it to automatic after operation. No matter how much water is stored in the water tower, you can press the “Hand” button and the “Stop” button to control the water level of the water tower to store more water before the power failure.
6: Automatically control the water pump operation by connecting to the detection line in the water tower to realize the water pump (pumping) when the water level is low, and stop the water pump (automatic water stop) when the water level is high, to adapt to the automatic water supply mode of the water tower, water tank and pool.
Introduction of pumping function: lower than low water level, automatic pumping is higher than high water level, automatic water stop button control: press the “hand” button in the lower right corner of the controller to start the water pump (when you want to pump, it will automatically stop), press the controller In the lower left corner of the stop button, you can turn off the pump. The pumping and draining functions are just the opposite. The drainage function is introduced: to high water (ie full water), the automatic drain is lower than the low water level, and the drain button is automatically stopped: press the hand in the lower right corner of the controller When the key is turned on, the water pump can be started (that is, the drainage starts, the water is automatically stopped at the low water level), and the water pump can be turned off by pressing the stop button in the lower left corner of the controller.
