4. The autotest master pulse tests Block A. Any faults on block A are noted.

Load

Block C outputs still

overridden ON

Failed Switch outputs still

overridden OFF.

Block A Pulse-tested.

5. The master resets all four blocks in the output group.

6. Overrides on block C are cancelled.

Load

Block C output overrides

cancelled.

Failed Switch outputs still

overridden OFF.

7. The master cancels overrides on block B except for any outputs that have tripped

erroneously.

Load

Overrides conditionally

cancelled.

8. The autotest master repeats the above process for blocks D/A/B, then A/D/C, then

B/C/D.

9. The autotest master reports faults to the other PLCs (if any). All the PLCs log any

faults that occur into their Fault Tables.

10. The autotest master continues testing with the next group.
