If the library has been successfully operating in the past, but is now
experiencing problems, check the following:
Control mode
. If you are using an application software package to
control CHM operations, the library must be set to SCSI Interface
mode. See page 47 for more information. If you are trying to operate
the library in one of the sequential modes, be sure to read
Appendix D.
Security
. Make sure that security is set correctly for the operation
you are trying to perform. If security is enabled, you cannot perform
many operations on the LCD and you cannot open the door. Security
can be enabled from the LCD (see page 32) or from your application
software with a SCSI command.
Door open
. Make sure the door is closed and locked. You can check
the Door Closed and Key Lock lines on the System Sensors screen
to determine if the door and key lock sensors are properly working
(see page 102).
CHM operation
. You can use the selections in the Diagnostics
Menu and the Demo Menu to determine if the CHM is functioning
properly. See page 113.
Fuse
. Make sure the fuse is good. See page 67.
