Submersible Timer with Pause Feature during Mains Failures
The post explains a submersible pump timer circuit programmed to cycle at 60 minute interval for watering the fields consistently. It also includes a time “memory” feature which ensures that the timer “remembers” the counting during mains failures, and restarts exactly from where it was interrupted when mains power is restored. The idea was requested […]
Submersible Pumpset Timer – Circuit Diagram and Working
The post details a timer circuit for submersible borewell pumpset which alternately switches the pumpset ON/OFF at a predetermined rate in order to allow the ground water sufficient time to restore at regular intervals and to ensure a consistent water supply to the attached overhead tank. The idea was requested by Mr. Siva. Switching Submersible […]
