So alone achievement

Slashstreetboy

So this is the last map related steam achievement I need to do. I don´t know if it´s worder weirdly or if I understood it wrongly.

"Repair the Generator in the Isolation Room in The Underground Complex and live to tell the tale."

I thought this meant repairing the gen in the room with the portal to the upside down with the broken elevator.

I´ve done so a couple of times by now. One time I escaped via hatch, 2 times via the gates, 1 time of when I escaped through the gate I didn´t do the gen completely on my own, the other two times I did.

My question is: Since it´s obviously not that gen that needs to be repaired for the achievement, which one is it? please help me out :)

Its the generator that will always spawn in its one little room upstairs, right above a spot for the basement to to appear
