Description
While the mechanism is in operation, should have been closed a door
was opened.
4 seconds have elapsed before completing the roller OFF
(the cam gear has not been rotated to the roller-OFF end position).
4 seconds have elapsed before completing the roller SET.
(During the roller OFF operation, 4 seconds have elapsed while the cam
gear is rotating in REV direction.)
Door can't be closed when the roller OFF has ended.
The cam gear attempted to do roller OFF/roller SET from an invalid
position.
door after the loading is complete.
An error will be indicated if the disc is still caught by the
phototransistor after 4 seconds of forced eject.
Although the cam gear has been rotated up to the roller OFF end
position, the roller can't be moved to the standby position.
4 seconds have elapsed before completing the lift DOWN operation.
4 seconds have elapsed before completing the lift UP operation.
(During the lift DOWN operation, 4 seconds have passed with the cam
gear rotating in REV direction.)
The lift DOWN complete cam gear has been displaced from its
specified position.
8 seconds have elapsed before completing the EJECT operation.
An error will be indicated if the disc is still caught by the
phototransistor after 4 seconds of forced eject.
HOME SW was still at ON position after 4 seconds of forced eject.
When forced eject was employed for the Bup failure during loading or
ejection,an error will be indicated if the disk is still caught by the
phototransistor after 4 seconds of forced eject.
10 seconds have elapsed before completing CRGIN operation.
(During CRGOUT operation, 10 seconds have elapsed with the cam
gear rotating in REV direction.)
10 seconds have elapsed before completing the CRGOUT operation.
Position of the CRGOUT complete cam gear has been displaced.
2 seconds have elapsed before completing 1-stage UP.
2 seconds have elapsed before completing 1-stage DOWN.
At the start of ELV, ELVSNS was not set to low.
(In case of starting from the 1st floor, ELHOME was not set to low.)
HLHOME was set to low though not on the 1st floor.
(There is a conflict between the floor number stored on the
microcomputer and the actual floor number.)
8 seconds have elapsed before completing the LOAD.
An error will be indicated if the disc is still caught by the
phototransistor after 4 seconds of forced eject.
Unauthorized foreign substance such as 8 cm disc has been loaded.
An error will be indicated if the disc is still caught by the
phototransistor after 4 seconds of forced eject.
