The Evil of the Daleks, waaaaay back in the Second Doctor's era. Check out the summaries for Episode 6 onwards, starting (at the end of Episode 5) with this:
Then the three test Daleks with the Human Factor activate; rather than being invincible killing machines, they are childlike and playful, forcing the Doctor into a game of trains with them.
You're right that baseline Daleks will hate the PPC's Daleks and probably jump directly to trying to kill them. So let's not send them on missions that put them in contact with the rest of the species, I guess?
