5.04 Fault Indicator
At initial power up, two lights will temporarily illu-
minate for 2-3 seconds to show the version of software
used.
To determine the first digit, count the function indica-
tors left to right, 1 through 5. To determine the second
digit count the pressure indicators, reading from bot-
tom to top, 0 through 7. In the example below the
Temp indicator and 75 psi indicators are on indicating
the version would be 2.3.

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 indictated in the pres-
sure indicators. The following table shows each of
the Faults possible.

Explanation of Faults
" UNDER PRESSURE: Indicates that operating
pressure is set too low and power supply output
power will be disabled.
INPUT POWER: Indicates primary line voltage is
outside the operating limits of the power supply
as selected by the setting of INPUT VOLTAGE
SELECTION SWITCH at the rear of the unit.
Low is 208/230 VAC and high is 460 VAC.
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
electrode, start cartridge or tip is missing or
excessively worn.
SHORTED TORCH: Indicates the torch or lead
has a shorted condition between positive and
negative 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.
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
Signal) 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.
