Hi 

I have a situation where i have two pumps.

1 pump will always run at one time 

But every 168 hours i want the pump to change to the second pump.

just looking at the best way to do this say using the weekly timer 

Thanks

Hi 

Thanks for getting back so quick 

I want the pumps to change then run for 168 hours then change again 

Thanks 

Andrew 

That works really well thanks 

I have attached what i had in mind but not sure if correct 

Hi 

if i wanted to have Q1 and Q2 not latch but give a short pulse output how would i achieve this.

Thanks

Andrew 

Hi Andrew,

See my change , i used a pulse block that i set by 1 second parameter and connected to Q3 & Q4.

Result that Q1 & Q2 are still all the time active and upon a change over Q3 & Q4 will pulse for a second.

If this time is notr correct just adjust the parameter in the two blocks.
