5.04 Fault Indicator
At initial power up, two lights will temporarily illuminate for 2-3
seconds to show the version of software used.
To determine the first digit, count the function indicators left
to right, 1 through 5. To determine the second digit count the
pressure indicators, reading from bottom 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 indicator lights de-
pending 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.

NOTE
Fault explanations are covered in the basic trouble-
shooting guide later in this chapter.
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 prop-
erly installed or tightened.
START ERROR: Indicates that the START SIGNAL was ac-
tive (ie. Torch Trigger depressed, hand held pendant
switch ON or CNC signal for torch ON) during one of
three (3) 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 (OUTPUT FAULT): This indicator has
two modes of operation:
First is the latched Fault mode. The 85 PSI LED blinks at
1 cycle per second, indicating that one of two fault
conditions exist.
1) A shorted condition in the torch, leads or consum -
ables.
2) Low or no output voltage from the inverter circuits.
In both cases, to reset the machine, turn the unit OFF,
identify and clear the problem and turn back ON.
