When the "Fault" indicator is ON or blinking it
will be accompanied by one of the pressure indica-
tor lights depending on what the Fault is. Only one
of these faults will be displayed at one time. If more
than one fault exists, when the first fault is corrected
and cleared, the next fault will then be displayed. It
is possible to have a fault indicated in the function
indicators and another fault indicated in the pressure
indicators. The following table shows each of the
Faults possible.

PART IN PLACE: Indicates that the shield cup is not
properly installed or tightened.
START ERROR: Indicates that the START SIGNAL
was active (ie. Torch Trigger depressed, hand
held pendant switch ON or CNC signal for torch
ON) during one of three conditions:
1) During initial power up when ON/OFF switch
is turned to ON position
2) When fault which had been disabling the
system is cleared.
3) When the FUNCTION CONTROL SWITCH
Mode is moved from SET position to any of
the other three (3) modes of operation.
CONSUMABLES MISSING: Indicates that the elec-
trode, start cartridge or tip is missing or exces-
sively worn.
SHORTED TORCH: Indicates the torch or lead has
a shorted condition between positive and nega-
tive leads.
INTERNAL ERROR: Indicates a microprocessor
error.
OVER PRESSURE: Indicates that operating pres-
sure is set too high. The Error Indicator will not
flash when the pressure is above 95 PSI. This
LED will remain ON and the system will operate
but pilot starting and cut performance may be
affected.
NOTE!
The cooling fans will turn ON as soon
as the unit is turned ON. After the unit
is idle for ten (10) minutes the fans will
turn OFF. The fans will come back ON
as soon as the torch switch (Start Sig-
nal) is activated or if the unit is turned
OFF, then turned ON again. If an over
temperature condition occurs, the fans
will continue to run while the condition
exists and for a ten (10) minute period
once the condition is cleared.
