Boot Fault (bF)
This fault will occur during the start-up sequence if an
active trigger signal is present. It is designed to prevent
immediate triggering after start-up as the unit should
be allowed to enter the “ready” state prior to being trig-
gered. This fault also prevents the high voltage from
being fired if the microprocessor resets. For additional
information, refer to the Fault Troubleshooting Section.

NOTE
NOTE
The boot fault error code displayed on the
uA display appears very similar to the ground
fault. Verify that the first character appears as a
lowercase “b” not the ground fault character “6”.
The boot fault
USUALLY
occurs during
the powering on of the voltage controller.
The boot fault
CAN
occur during painting if a
brown out or arcing situation in the gun, cable of
high voltage section cause a system reset.
The ground fault error code displayed on the
uA display appears very similar to the boot fault.
Verify that the first character appears as a “6” rep-
resenting the character “G” and not a lowercase
“b” for a boot fault.
Ground Fault (GF)
If this fault occurs, the fault indicator on the control unit
will illuminate, a GF indication will show in the uA dis-
play. This fault will occur if the microprocessor detects
a loss of ground at the high voltage section. If this fault
occurs, reset the fault. This fault can be caused by a
broken ground path between the high voltage section
and the pc board. In external cascade applications,
a failed low voltage cable can cause this problem.
Check the wiring to the high voltage section. For more
information, refer to Fault Troubleshooting Section.
Cable Fault (CF)
This fault will occur if high voltage is active and the mi-
croprocessor detects that no current is being supplied
to the high voltage section. This indicates a connection
problem from the control unit to the high voltage section
or external cascade. Check the wiring harness for loose
pins, or replace the high voltage section. In external
cascade applications, a failed low voltage cable can
cause this fault. For additional information, refer to the
Fault Troubleshooting Section.
