When the higher-level water level switch indicates the water level is high, and the lower-level water level switch indicates the water level is low, the water level switch is reported to be faulty; if there is no such fault setting, the unit will start and stop abnormally. If the fault has disappeared, it can automatically recover. The water level detected by the unit is abnormal, that is, if water is detected at the higher level, and the lower level is not detected, the system will report a water level switch failure.
The main reasons that may cause the failure of the water level switch for water tank are as follows:
1) The four electrodes of the water level switch for the water tank are connected in reverse.
2) The surface of the water level switch electrode is severely scaled.
3) The motherboard interface is connected incorrectly.
4) The electrode wire is open or broken.
If you encounter a failure of the water level switch for water tank in the actual project, you can perform the fault diagnosis according to the following troubleshooting idea diagram to ensure that you can find quickly the faults of the unit and complete the repairs.
As some industries are so special, the price of water tank switches could be very high because when a thing is scarce, it is precious. Precious things cost much. Well, FEEJOY offers a more versatile and moderate choice such as RF admittance level switch, capacitance level switch and rotary paddle type level switch.
Water tank automatic price will be reasonable for even special custom needs. The water tank automatic switch of FEEJOY could be an all-purpose switch for multiple applications.
