restarted
1. Check the mode switches on primary and backup
CPU boards. Restart the backup CPU with the
mode switch in the same position as the primary
CPU had when it was last restarted.
NOTE
If position “AUTO” does not work then
switch to “CLEAR” or vice versa.
2. Check size of primary memory on primary and
backup CPU boards (8/16 MByte). Make sure
they are equal and restart the backup (or the
system).

it is probably due to interference, program error or
special hardware fault.

03 RAM fully occupied
04 Addressing error in system mode
