9060 High Voltage Controller - Operation
CP-13-05.3

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. In external cascade applications, a
failed low voltage cable can cause this fault.
For additional information, refer to the Fault
Troubleshooting Section.
Any
fault code not listed that appear on
the screen are a likely indication of a PC
board failure due to possible arc damage.
N O T E
Boot Fault (bF)
This fault will occur during the start-up se-
quence 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 Trou-
bleshooting Section.

TRIGGER SIGNAL TIMING:
The trigger signal minimum hold time is 10 ms.
Figure 35: Cable Fault Display
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 or external cascade. 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 Troubleshoot-
ing Section.
The boot fault error code displayed on
the uA display appears very similar to the
ground fault. Verify that the first character
appears as a lowercase “
b
” not the
ground fault character “
6
”.
The boot fault
ONLY
occurs during the
powering on of the voltage controller.
N O T E
The signal Hold Times are the minimum
required for the processor to detect the
signal. During actual operations, signal
time durations are expected to be much
greater than the minimums.

FAULT DESCRIPTIONS
For in depth troubleshooting information on
the 9060, please refer to the “Fault Trouble-
shooting” portion of the Maintenance Section
of this service manual.
If a fault occurs, the
Fault Indicator on the front of the Controller
will light and a fault code will be displayed on
the microamp (µA) display. Faults can be
reset by pressing the Reset button on the front
of the Controller or by using the remote I/O
reset signal.
