Indicates a malfunction in the primary power circuit.
Indicates the left side thermal protection circuitry is
malfunctioning.
Indicates left side of unit has overheated. Unit has shutdown to
allow fans to lower left side temperature. Operation will continue
after unit is within normal temperature range.
Indicates the right side thermal protection circuitry is
malfunctioning.
Indicates right side of unit has overheated. Unit has shutdown
to allow fans to lower right side temperature. Operation will
continue after unit is within normal temperature range.
Indicates operation at maximum input current.
Output voltage exceeded 100 VDC for more than 1/2 second.
Precharge did not complete in allotted time.
System cannot measure output voltage.
Indicates thermal protection circuitry on the Process Control
board is malfunctioning.
Indicates PC2 has overheated. Unit has shutdown to allow fans
to lower temperature.
Indicates thermal protection circuitry on the System Power
board is malfunctioning.
Indicates PC3 has overheated. Unit has shutdown to allow fans
to lower temperature.
Indicates the control supply on PC2 is malfunctioning.
Indicates input primary line voltage is too low.
Primary line voltage must be at least 90% of specified nominal
voltage.
Indicates the boost circuitry on the right side of unit is
malfunctioning.
Indicates button is stuck on the power source upon start up.
Fault will clear when button is released.
Indicates the relay circuitry (W1, W2) is malfunctioning.
Indicates a stuck remote contactor in either Stick or TIG pro-
cess.
Indicates the thermistor in the attached FieldPro accessory is
malfunctioning.
Indicates the attached FieldPro accessory has overheated.
Indicates internal communication malfunction to PC7.
Indicates internal communication from primary power circuitry
to secondary power circuitry on PC1.
Indicates serial communication was initially made and is now
malfunctioning. May appear normally during firmware updates.
Communication between PC1 and PC5 malfunction.
Indicates serial communication is malfunctioning. May appear
normally during firmware updates. Communication between
PC1 and PC5 malfunction.
