Fault code description, power source
The fault codes for the control panel, wire feed unit and the remote control unit are
described in the manuals for these units. This manual describes the fault codes for the
power source.
Fault
code
Description
1
EPROM check sum error -- program memory error.
Check sum test of the program memory, which is run only when initiating the power
source after power--up. This fault does not disable any functions.
The program memory is damaged. This is a serious fault, that can have unforeseen
effects.
Action: Restart the machine. If the fault persists, load new software via ESAT. If the
fault still persists, replace circuit board CB0, which carries the memory chip.
2
Microprocessor RAM error.
The microprocessor is unable to read/write from/to a particular memory address in
its internal memory. This test is preformed only on initiation after power--up. This
fault does not disable any functions.
Action: Restart the machine. If the fault persists, replace circuit board CB0, which
carries the microprocessor chip.
3
Memory error, external RAM.
The microprocessor is unable to read/write from/to a particular memory address in
its external memory. This test is preformed only on initiation after power--up. This
fault does not disable any functions.
Action: Restart the machine. If the fault persists, replace circuit board CB0, which
carriesthe microprocessor chip.
