He hovered his finger over the 'Clear Code' button. One press, and Unit 734 would revert to a dumb machine, just a pile of yellow steel and hydraulics. But the code VPV001-05 wasn't an error to be fixed. It was a birth.

• Thermal (Overload): Slow trip for prolonged over-current.
• Magnetic (Short/Low Voltage): Instant trip.

The Diagnosis:
