You absolutely do not want to set repeat every minute, also whole campaign with 5s duration? that seems a bit odd.
Anyway, you will want to schedule campaign (or single layout) to your display, most likely like this:
start 10:00
end 10:30
with repeat daily
Start (Now)
End date far into the future
without repeat
Perhaps have a look at this topic regarding durations - Understanding Media Duration and how it affects the playback of a Layout
