It looks like there’s a timer relay set at 20 seconds.

to go back to utility does it on its own we never had problems with that part of the switch so didn't interfere with that side of things i think it takes a couple minutes after utility returns and just switches it's self

the timer relay is just for switching to generator we had to bump that up to 40 sec to give generator a chance to start and run a few seconds before switching

Errr. That’s weird. On the generac switch, releasing 23 from ground causes transfer back to utility. You would think that when utility is restored, the 2nd relay would drop out 23 and it would switch immediately unless there was a timer.

Oh i see what you mean as long as there is no utility 23 to ground is maintained
Timer relay only pauses the 2nd relay before it engages, when time runs out relay will hold 23 to ground until 1st relay senses utility again
