Just their confusion. They don't know what to do without the emergency generator.
When you step into the room, you see the massive emergency generator and the small maintenance crawlspace surrounding it. First thing you notice that's wrong- crackles of energy are playing across the surface of the generator and glowing from within. You don't think it is supposed to do that.
It is. If you had tried disabling them by hand, you may electrocuted yourself. If you had tried removing them with your lightsaber, you may have slipped and damaged the generator further with your weapon that can cut through anything.
And so you concentrate small pushes with the Force, breaking each EMP until the damaging effects they are having on the generator cease.
Inspecting the generator, you figure that the rest of the repair work will be beyond your capability. Reporting to the guard, they tell you that they will send someone back to help you.
Con, after hearing that back up should arrive shortly, takes a moment to catch his breath and then contacts his master once more "Master? I may have been too hasty. It seems I was able to destroy the EMPs. The generator is still not functioning, but a mechanic should arrive here shorly. Should I stay here and wait for him?"
