The following table describes the normal states and functions of the status and diagnostic LEDs on the circuit
boards in the generator.
A change in the state of an LED may be for a brief duration, especially during a fault or an exposure.
5.4.1
Dual Speed Starter Board
LED NORMAL
STATE
FUNCTION
DS1
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.
5.4.2
Generator Control Board
LED NORMAL
STATE
FUNCTION
DS1
Flashing
Flashing at 1 Hz to indicate the generator CPU is functioning.
DS2 Flashing
Flashes to indicate that the generator control board is sending
data to the console.
DS3
Flashing
Flashes when data is being sent to the generator control board
by the console
DS4
Flashing
Flashes to indicate that the generator control board is sending
data to the COM port J21
DS5
Off
Lit when in PREP state
DS6
Off
Lit when in XRAY state
DS7
Flashing
Flashes to indicate that the generator control board is sending
data to J22 on the generator control board.
DS8
Flashing
Flashes when data is being received from J22 on the generator
control board.
DS9
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.
DS10
Off
If lit, indicates rotor is in high - speed operation.
DS11
Off
Lit when in Prep state.
DS12
Flashing
Flashes when data is being received from COM port J21 on the
generator control board.
5.4.3
HV Auxiliary Board
LED NORMAL
STATE
FUNCTION
DS1 On
Indicates
presence
of the +24 VDC supply.
5.4.4
EMC Capacitor Board
LED NORMAL
STATE
FUNCTION
DS1
On
Indicates the DC bus capacitors are charged.
