Internal Fault
System error
2
Start up error:
HW/SW mismatch
No
No
Yes
If relay SW has just been updated, redo
it. If not recovered, contact your nearest
ABB representative to check the next
possible corrective action.
Internal Fault
System error
2
Start up or runtime
error: Data bus er-
ror, CPU module
Yes (2)
Yes (3)
No
Restart the relay. If recovered by restart-
ing, continue relay normal operation. If
not recover by restarting, replace the re-
lay, most probably hardware failure in
CPU module.
Internal Fault
System error

Start up error: SCL
file missing
No
No
Yes
Do factory restore or rewrite configura-
tion using PCM600.
Internal Fault
System error
2
Start up error: Miss-
ing order number
No
No
Yes
Do factory restore. If not recovered,
contact your nearest ABB representative
to check the next possible corrective ac-
tion.
Internal Fault
System error
2
Start up error: FPGA
HW error, CPU mod-
ule
Yes (2)
Yes (3)
No
Restart the relay. If recovered by restart-
ing, continue relay normal operation. If
not recover by restarting, replace the re-
lay, most probably hardware failure in
CPU module.
Internal Fault
System error
2
Start up error: FPGA
image corrupted,
CPU module
Yes (2)
Yes (3)
No
Restart the relay or if relay SW has just
been updated, redo it. If recovered by
restarting, continue relay normal opera-
tion. If not recovered by restarting or
redoing SW update, replace the relay,
most probably hardware failure in CPU
module.
Internal Fault
System error

Runtime error: CPU
internal fault
Yes (2)
Yes (3)
No
Restart the relay. If recovered by restart-
ing, continue relay normal operation. If
not recover by restarting, replace the re-
lay, most probably hardware failure in
CPU module.
Internal Fault

Start up error or
runtime error: file
system error
Yes (2)
Yes (3)
No
Restart the relay. If recovered by restart-
ing, continue relay normal operation. If
not recover by restarting, replace the re-
lay, most probably hardware failure in
CPU module.

Start up error:
Watchdog reset has
occurred too many
times within an
hour. Note! This is

No
No
Yes
Restart the relay. If recovered by restart-
ing, continue relay normal operation. If
not recover by restarting, replace the re-
lay.

Runtime error: Faul-
ty Signal Output re-
lay(s) in card loca-
ted in slot X105.
Yes (2)
Yes (3)
No
Check wirings. Restart the relay. If re-
covered by restarting, continue relay
normal operation. If not recover by re-
starting, exchange the hardware mod-
ule in slot X105.
