DS2 Power Current Hot Yellow Normal status: ON
ON at the start of an exposure preparation.

charge or there is no command to heat.
DS3 Filament Over Charge Red Normal status: OFF
ON when the heater current is too high or when the
Generator Interface board sent a false command.
OFF when the filament is operating properly.
DS4 Over Intensity on Stator Red Normal status: OFF
