LB-220v submersible pump leakage protection

First, the detection relay Introduction Submersible pump leakage protection relay is designed to detect submersible pump water sensitivity of the resistance. Sensors use electrode sensors. When the pump body leakage occurs, the control relay will issue a corresponding control signal, so that staff on the pump leakage treatment. Controller in the circuit design to take a series of anti-jamming measures, can work in a very serious electromagnetic interference environment. Second, the functional overview Detection Relays are used water sensitive sensor to provide a signal to determine whether there is leakage within the submerged pump cavity; water sensitive resistance sensor detects the cavity resistance to the ground, such as below the controller set value The relay will operate and the red light on the panel will alarm. At the same time, the controller 5, 6 and 7, 8 terminals will output a set of switch signals to cut off the main control circuit of the submersible pump and output a set of passive switch signals Effective protection of the submersible pump can only work in a safe situation. If the controller will automatically reset after troubleshooting, then the pump can continue to run. The given value of the resistance is standard, can also be set according to the requirements. Users have special needs must be contacted in advance.
