c9 drafted · lead Trip (production stops)

Arc protection activated; unit must restart

review note: support check: partial - Arc protection activated and unit restarts, implying stop, but trip is not explicitly stated.

c10 drafted · lead Manual reset (operator restarts or acknowledges)

First occurrence cleared by operator restart; persistent case needs service

review note: support check: partial - First occurrence: operator presses ESC and restarts; persistent: contact assistance; manual-reset is implied rather than stated.
