Ransburg 9060 LV Cascade Controller 80120-XXX - Manual (Page 45)

9060 Cascade Low Voltage Controller - Operation
CP-13-02.3 40
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 Troubleshoot-
ing” 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.
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.
Cable Fault (CF)
This fault will occur if high voltage is active and
the microprocessor detects that no current is
being supplied to the applicator. This indicates
a connection problem from the control unit to
the external cascade. 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.

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.
Figure 34: Boot Fault Display
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.

TRIGGER SIGNAL TIMING:
The trigger signal minimum hold time is 10 ms.
