I have to make a ladder logic for a pumping station for 4 pumps, 3 duty and 1 standby, How can I change the duty of a pump if it is running for a long time?
three pumps are interlocked to level measurement from a level transmitter, if 20% level than 1st pump starts, if 45% level then 2nd pump will start and if level of tank is 75% than 3rd pump will start and for level is 90% ,4th pump will also start...
But if for a long time level is 25-40% than only pump 1 will have to run continuously, that could increase its worn...I want to change duty in such case.
experts kindly help,
It will be a great favour from your side.
Thanks in advance
