Fault codes marked with an asterisk ( * ) are not displayed by the control panel. but they
are stored in the fault log. To get access to the fault log use the ESAT service tool. See

Fault code description
This manual describes the fault codes for the power source. The fault codes for the other
units are described in the manuals for these units.
Note! The welding data unit is operated by the processor of the control board in the power
source. The fault codes for the welding data unit are described in the service manual for the
control panel.
Power source
Code Description, power source
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 20AP1, 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 20AP1, which carries
the microprocessor chip.
3 Error in external RAM
Read/write test of the processor’s internal external RAM. This test is preformed only as part
of initiation after power--up. The microprocessor is unable to read/write from/to a particular
memory address in its external memory. This fault does not disable any functions.
Action: Restart the machine. If the fault persists, replace circuit board 20AP1, which carries
the microprocessor chip.
4 5 V power supply too low
The unregulated power supply voltage (+24 V) is too low: the smoothing capacitors cannot
keep the voltage up enough for the processor to continue to operate. The processor stops all
normal activities, expecting to be shut down.
Action: Turn off the mains power supply to reset the unit. If the fault persists, check the
power supply to circuit board 20AP1.
