Pump Changeover

[tommyrush]

Hi there

Im looking for some Help! Does any one have an example for a pump change over circuit?

I have 2 pumps that i have to control.

(Pump Selection )

I1 = Pump 1 - Pump 2
I2 = Pump 2 - Pump1

If the overload or the flow switch failes(I4) it will select the next pump after a delay of 1min. When a reset button is pressed (I3) it wll change back over on to the lead pump that is selected via the switch (I1 or I2).

Regards

Tommy

Tommy,
see my attached example.Easy-Soft V 5.11pro.
I use two jumps.That works in conjunction with I01 and I02 like a program selector switch.
May be it can serve as a basic for your application.
