FAULT DESCRIPTIONS
When a fault occurs, the Fault Indicator on the front of the control unit will light, a fault code will be displayed on the sta-
tus meter. Faults can be reset by pressing the Reset button on the front of the control unit .
Cable Fault (CF)
This fault will occur if high voltage is active and the microprocessor detects that no current is being supplied to the ap-
plicator. Typical causes include a broken or improperly connected low voltage cable. Other causes could include loose
wiring in the control unit or a faulty cascade circuit in the applicator. When this fault occurs, determine the cause of the
problem, then press the reset button.
Over Voltage Fault (OU)
This fault will occur if the microprocessor detects the unit is trying to output voltage above that
required for the application. If this occurs, reset the control unit. If this fault continues to occur, replace the main PC
board.
Safety Fault (SF)
If this fault occurs, the fault indicator at the control unit will illuminate, a SF indication will show in the status display. This
fault will occur if the microprocessor detects the unit is trying to output voltage to the applicator with no trigger. If this
occurs, reset the fault from the control unit. If this fault occurs repeatedly upon reset, replace the main PC board. Other
causes of this fault include a broken ground path between the applicator and control unit caused by a faulty cable or plug
assembly.
