Something I don't understand

What I don't understand is what is the purpose of the GCU.

From what is described, I see a black box of some sort with a finite counter in it, that is capable of shutting down the generator when that counter overflows.

Given that a generator is a reasonably straightforward thing, what kind of improvement can one have in mind attaching to it a box that shuts it down for something as predictable and maybe trivial as an overflowing finite counter?

Help me. I really am trying to understand.
