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.

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.

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 triggered.
This fault also prevents the high voltage from being fired
if the microprocessor resets. For additional information,
refer to the Fault Troubleshooting Section.
