Ease of Operation, Ease of Wiring.
This is used for One Pump operation where all the parameters such as Voltage, Current, Auto/Manual, Water Tank Level & Error Alarms would be displayed with respect to that pump.
There are 3 Pumps which operate as per the pressure input provided by the Pressure switch. In this when the pressure is at normal value only one pump would be operated. When the pressure drops below set value & the operating pump is not able to fulfill den the drive would start the second pump & similarly third.
If the set value is achieved, then it would gradually stop the pumps in the manner they started.
Until the top level is High the pump would be filling & after it is high the pump would stop.
This helps in preventing repeated starts thus protecting the pump. If bottom tank level is High, then only it would fill the TOP Tank. |
