The mA/Rotor Board also has a filament protection circuit (U23C) to detect unusually
high voltages coming from the filament power supply and to then initiate a filament
fault signal that will disable the generator’s ability to generate an exposure. An
additional circuit on the same board can be used to detect unusually long periods of
filament operation at boost levels, and to initiate the same filament fault signal.
