Intelligent Water Pump Control Box

AS3 water pump controller applies for many kinds of pump, such as submersible pump, slush pump, centrifugal pump, stage pump, well pump and so on,  the input voltage is AC380V (50-60HZ),±10%,THREE PHASE and matching power are 0.75-4KW, 1-7.5KW, 2.2-11KW, 2.2-15KW

Control Method
Ø  Control water supply by probe
Ø  Control water supply by float switch
Ø  Control water supply by pressure gauge and pressure tank

Water Supply by Probe
 
1)The motor starts while the water in the water supply tank drops to the mid level.
2)The motor stops while the water in the water supply tank reaches the high level, the low level probe works as loop.
The water drainage tank can't connect probe once the no load protection is set up. 

Water Supply and Water Drainage Work Together by Probe
 
1) The motor starts while the water in the water supply tank drops to the mid level and stops while it reaches the high level, the low level probe works as loop.
2)  The motor starts while the water in the water drainage tank reaches the high level and stops while it drops to the mid level, the low level probe works as loop.(No load current be set up 0.00A)
As the standard probes qty. we supply is 3pcs, please buy addition 3 probes under this working condition.

Water Drainage by Probe
 
1)The motor starts while the water in the water drainage tank reaches the high level.
2)The motor stops while the water in the water drainage tank drops to the mid level, the low level probe works as loop.(No load current be set up 0.00A)
Because the sewage has strong corrosiveness, we suggest that equip with float switch for monitoring while enable 'water drainage' function for draining sewage.

Water Supply by Pressure Tank
 
1)  The motor starts while pressure drops to min. pressure contactor.
2)  The motor stops while pressure rises to max. pressure contactor, the movable contactor works as loop.
The pressure tank volumn should be appropriat. Otherwise, the pump will restart frequently.

Water Supply by Float Switch
1)The motor starts while the float switch goes the bottom of water supply tank.
2)The motor stops while the float switch goes the top of water supply tank.

Water Drainage by Float Switch
1)The motor starts while the float switch goes the top of water drainage tank.
2) The motor stops while the float switch goes the bottom of water drainage tank.
