(OHDOL2DR/23)
This model is suitable where overhead tank capacity is small and underground tank capacity is large.
This model is suitable for the controlling the overhead tank water supply as soon as the overhead tank gets empty. The pump will start and the underground tank water will be lifted to overhead tank. The pump will be stop when the overhead tank gets full.
The controller has a protection for pump Dry run safety which senses the water reaching to overhead tank within the 60 seconds whenever pump starts. If the water is not reaching to the overhead tank within the specified time it trips the pump and gives audio visual alarm. Thus protecting the pump from damage. The audio visual alarm will be reset by the application of Reset switch & pump will start if dry run fault is rectified.
The controller has a redundant pump facility. One pump at a time will operate. In case of failure of first pump we can able to operate another pump. v
