Over Voltage Fault (OU)
This fault will occur if the microprocessor de-
tects 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.

Feedback Fault (FF)
This fault will occur if the microprocessor de-
tects a loss of the current feedback signal. If
this occurs, reset the fault. If this fault occurs
repeatedly, replace the cascade or send the
high voltage controller in for repair.

DI/DT Overload Fault (dOL)
This fault is ONLY applicable to 80100-51X
units. This fault will occur if the microproces-
sor detects that the rate of current change has
exceeded the limits specified in the user DI/DT
settings. If this occurs, reset the fault. Check
to ensure that no object is moving toward the
applicator within the minimum safe distance,
adjust the DI/DT settings if necessary, and re-
test operation. If this fault continues to occur,
contact your Ransburg Representative.
