No. Test Name Description
1 Poweron Checks all digital data paths and normal machine
operation. This test runs the same sequence of TESTS
as when initiated by an actual power on, but does NOT do
all operations (see below).
Sequence Order:
3 - Controller Test
40 - Power Supply Test
– - Motor Connection Test (no number)

of a move, the autochanger tries a ‘‘restore’’ of the
last move. The autochanger tries to put the cartridge
back to where it came from. This attempt could fail
(Poweron sequence would fail). POWERON ONLY.
10 - Initialize Element Status (if needed).

– - Mailslot rotation (if not secured). This rotation
could fail(Poweron sequence would fail). POWERON
