Ground Fault (GF)
If this fault occurs, the fault indicator on the
control unit will illuminate, a GF indication will
show in the uA display. 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.
Figure 24: Ground Fault Display
Cable Fault (CF)
This fault will occur if high voltage is active and
the microprocessor 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 addition-
al information, refer to the Fault Troubleshoot-
ing Section.
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, or replace the pc board. See Fault
Troubleshooting Section for more information.
