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.
User can use LEVEL PROBES or FLOAT SWITCH to measure the level of the Bottom & Top Tanks.
There are 3 Pumps which operate as per the pressure input provided by the Pressure sensor. In this when the pressure is at normal value only one pump would be operated through drive. 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 gradually increasing the speed of it.
If the set value is achieved, then it would gradually stop the pumps in the manner they started.
Maximum 3 pumps can be operated.
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.
