Could anyone help me to elaborate a ladder program for AB Micrologix 1500 to control five pumps in turn?
Some especifications:
Theres is a watertank 920m above floor level) and a reservoir (under the groud), both with ultrasonic level sensors. The pumps (15HP) draw
the water to tank from the reservoir. They work in turn: when four of them work, the other one pauses for 24 hours. They power-on when the
level of the watertank is low and the level of the reservoir is not low. They power on from 15s to 15s one after the other. They can´t
power-off together.They power-off from 15s to 15s one after the other.
I must use RSLogix 500.
Forgive me for my poor English.
Thanks.
