its 2 duty 1 standby pump

How about you post what you've done so far and we'll help from there

i have arranged a program in zelio soft 2
but i couldnt upload it. i will send you the power and control diagram. also these 3 pumps should be working alternatively. on first run pump 1 and pump 2 should work. in the second run pump 2 and pump 3 should work. in the third run pump 3 and pump 2 should work and this cycle continues. in all these the second pump act as an assist to the first pump. i will share the power and control diagram. i am not getting the logic to do these. thats why i am stuck.
