9060 Cascade Low Voltage Controller - Operation
39 CP-13-02.2
Reset Signal
While in REMOTE mode, if a fault occurs, the
fault can be detected by the control system
using the fault relay contact outputs. If the fault
relay signal is active, the Reset Signal can be
used to clear the fault status. To clear a fault
using the reset signal, turn off the trigger signal,
then turn on the reset signal for approximately
10 ms to reset the fault.. Then turn off the reset
signal.
RESET SIGNAL TIMING:
The reset signal has a minimum hold time of 10
ms.
Trigger Signal
The trigger signal is used to activate the High
Voltage output from the cascade.
TRIGGER SIGNAL TIMING:
The trigger signal minimum hold time is 10 ms.
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 display. Faults can be reset by
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.
N O T E
There is a 5 second fault reset delay
timer that inhibits the triggering of high
voltage immediately after a fault reset.
The Reset button on the front panel can
also be used in REMOTE mode to clear a
fault condition as long as the front panel
lockout jumper is not installed.
N O T E
pressing the Reset button on the front of the
Controller or by using the remote I/O reset
signal.
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.
