Operating Principle
Automatic Mode:
The controller continuously monitors the water level in the underground and overhead tanks. When the overhead tank requires water and sufficient water is available in the underground tank, the controller switches the pump ON. When the overhead tank reaches the high-level condition, the pump switches OFF. The controller also prevents pump operation when the underground tank reaches its low-level condition.
Manual Mode:
The pump can be operated using the START and STOP controls, subject to the controller’s safety/interlock functions.
