NORMAL STATE
Off If lit, indicates that excessive current has been drawn from the
DC Bus. This indicates a DSS fault, if lit without a tube stator
connected.
NORMAL STATE
Flashing Flashing at 1 Hz to indicate the generator CPU is functioning.
Flashes to indicate that the generator control board is sending
Flashing
data to the console.
Flashing Flashes when data is being sent to the generator control board
by the console
Flashing Flashes to indicate that the generator control board is sending
data to the COM port J21
Off Lit when in PREP state
Off Lit when in XRAY state
Flashing Flashes to indicate that the generator control board is sending
data to J22 on the generator control board.
Flashing Flashes when data is being received from J22 on the generator
control board.
Off Indicates rotor ready (sufficient stator current)
In low speed mode DS9 is on at prep.
In high speed mode DS9 is on after prep completed.
Off If lit, indicates rotor is in high - speed operation.
Off Lit when in Prep state.
Flashing Flashes when data is being received from COM port J21 on the
generator control board.
NORMAL STATE
On Indicates presence of the +24 VDC supply.
NORMAL STATE
On Indicates the DC bus capacitors are charged.
