Voltage Cable Fault (UC)
This fault will occur if the microprocessor detects
a loss of the voltage feedback signal. This can be
caused by a failed high voltage cable, a failed high
voltage section, or a failed pc board.

Over Voltage Fault (OU)
This fault will occur if the microprocessor detects the
unit is trying to output voltage above the required for
the specific applicator type. If this occurs, reset the
Controller. If this fault continues to occur, replace the
main PC board.
Current Limit Fault (CL)
This fault occurs if the output current exceeds the
maximum current by 20µA. This fault can be caused
by excessive overspray on the applicator or a paint
formulation that is too conductive. It may also be
caused by a bad pc board. Clean the applicator, check
the paint formulation, or replace the pc board. See
Fault Troubleshooting Section for more information.
Overload Fault (OL)
This fault will occur if the overload feature is active
(see ‘Overload Activation” previously in the “Operation”
section) and the output current exceeds the overload
current value. This can be caused by excessive
overspray on the applicator or paint formulation that is
too conductive. Clean the applicator, check the paint
formulation, or move overload jumper (JP17) to the
open position.
Feedback Fault (FF)
This fault will occur if the microprocessor detects a
loss of the current feedback signal. If this occurs,
reset the fault. If this fault occurs repeatedly, refer to
the Fault Troubleshooting Section to determine if the
problem is with the high voltage section or the main
pc board.
