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.

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 power source. 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 performed only on initiation after power-up. This fault does not
disable any functions.
Action: Restart the power source. 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 performed 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 power source. If the fault persists, replace circuit board 20AP1, which
carries the microprocessor chip.
