Shutdown Sequence

Before shutting down the power supply, it is necessary to perform the HDD completion process (Purpose: to prevent damage on
the HDD) and execute the fixing disengagement operation. This series of process is called "shutdown sequence".
With this machine, the Main Controller PCB detects turning OFF the Main Power Supply Switch, and the shutdown sequence is
started and executed automatically.
Note that the maximum shutdown time with this machine is 90 seconds. (If the maximum of 70 seconds has elapsed, the power
supply is turned OFF by the hardware timer circuit on the Low Voltage Power Supply PCB.)
NOTE:
If the power supply is stopped without shutting down the machine, or if the processing to completely delete the hard disk (deletion
of the primary file) fails to be completed within the shutdown time (max. 70 sec.), data consistency is checked at startup. In such
a case, startup takes up to 80 seconds. The progress bar is displayed during the data checking.
