OV Fault
This fault occurs when the system output voltage exceeds the maximum allowable
voltage, +10% above the programmed voltage or for full output operation.
This may be caused by:
System Control PWB failure
Filament/Feedback PWB failure
HV
Divider
Failure
Diagnosis
The OVER VOLTAGE FAULT LED will be illuminate.
HV output will be disabled.
Over Current Fault
This fault occurs when the HVPS output current exceeds the maximum allowable
current..
This may be caused by:
X-Ray tube, HV cable
Regulator PWA failure
Low End PWA
Diagnosis
The OVER CURRENT FAULT LED will illuminate.
HV output will be disabled.
Temperature Fault
This fault occurs when a high temperature condition is detected on the inverter
assembly. The system control board then latches the temperature fault to prevent
damage to the inverter.
This may be caused by:
Ambient temperatures beyond specification
Diagnosis
The Over Temp LED will illuminate.
HV output will be disabled.
Check the ambient temperature of the room. It must be less than 60ºC.
