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 ap-
plicator or paint formulation that is too conduc-
tive. Clean the applicator, check the paint for-
mulation, or move overload jumper (JP17) to
the open position.

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 ap-
plicator or a paint formulation that is too con-
ductive. It may also be caused by a bad pc
board. Clean the applicator, check the paint
formulation, and re-test. If still a problem, re-
place the pc board. See Fault Troubleshooting
Section for more information.

Voltage Cable Fault (UC)

This fault will occur if the microprocessor de-
tects 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. Replace the high voltage cable and
re-test. If still faulty, replace the high voltage
section or pc board and re-test.

The ground fault error code displayed

on the uA display appears very similar to
the boot fault. Verify that the first charac-
ter appears as a “6” representing the
character “G” and not a lowercase “b” for
a boot fault.
