PowerOn
This mode behaves like INVENTORY, but it only start

terruptions
This section deals with the effects of interruptions to Sequential operation. These
interruptions include:
•
Power Failure/Interruption.
•
Violation of the Inventory
•
Unrecoverable Handler Fault.
Power Failure/Interruption
A power failure is an unintentional occurrence, while a power interruption is most
likely the result of someone intentionally turning the power off. Unfortunately, the
changer cannot distinguish between the two events. Under the Manual mode of the
Start menu the changer cancels any previously–running sequential operations when
power is applied (or reapplied). Under the Inventory and PowerOn modes the chan
will attempt to continue from where it left off when power is applied (or reapplied).

use the Move command in the Operation/Move Cartridge page to return the cartridge
to its proper magazine storage location.
nrecoverable Handler Fault
An unrecoverable handler fault is a condition that requires operator intervention: for
example, a cartridge incorrectly inserted into a storage matrix slot. The condition
should be corrected before continuing.
