Arc Fault
This fault occurs when the system output has experienced arcs beyond the maximum
allowable of one arc.
This may be caused by:
Problems with the x-ray tube
Failure in the HVPS High Voltage Assembly ,Filament Transformer section
High Voltage Cablewell
Diagnosis
The Arc Ext. FLT, LED will illuminate.
Issue a reset and set 1/2 Maximum rated kV output.
Listen for multiple arcs and attempt to localize the problem to X-Ray Tube or
HVPS.
If none are detected, via the interface, issue a reset and set Maximum rated kV
output.
Listen again for multiple arcs and attempt to localize the problem to X-Ray Tube or
HVPS.
For X-ray tube problems, refer to the appropriate documentation.
Filament Fault
This fault occurs when the system detects a problem with the filament selection or
filament current regulation.
This may be caused by:
System control board PWA failure
Filament Inverter Problem
X-Ray tube’s Filament
Diagnosis
The Filament Fault LED will illuminate.
Via the control interface, issue a reset and command the filament in pre-heat
mode.
Check X-Ray tube’s Filament
