Figure 3-11 HVPS Front Panel LEDs when Subthreshold Arcing is Occurring
If arcing surpasses either a frequency or a time-duration threshold, a latching
OUTPUT
ARCING
fault will occur. (These threshold values are detailed in Figure 5-8.) The
OUTPUT
ARCING
and
POWER SUPPLY FAULT
LEDs will then light red, while the
HV OUT OF
REGULATION
LED will turn green and the
ART/OUT OF REGULATION
LED will no longer
flash. In addition, the
HV ON
LED is extinguished, as the fault condition causes the HV to be
switched off. This latched-fault state is illustrated in Figure 3-12.
Figure 3-12 HVPS Front Panel LEDs when a Latched OUTPUT ARCING Fault Has Occurred
If the
OUTPUT ARCING
fault occurred solely because intermittent arcing passed one of the
threshold conditions, the HV should come back on as soon as the RESET and HV ON signals are
supplied. Out-of-regulation faults arising as a result of other conditions will likely require
troubleshooting. To address such cases, see Ishikawa Diagram #11 and Table 5-16.
