    DRM-7000, DRM-AF751, DRM-AL751, DRM-AH721, DRM-PW701 7.1.2 TROUBLE SHOOTING 1. Basic Concepts A condition in which normal changer operation cannot be continued is defined as "error status." When SCSI commands are used for operations, a check condition is returned to the host computer if an illegal command is sent. However, if normal operation can be executed by sending a legal command, this is not "error status."...

Quitting from Nonfatal Error Status (Mainly Errors with the Drive) When an error occurs during mechanism initialization: (Check whether it is the UNLOCK status.) FUNCTION • If the indication returns from "Initializing" to an error indication again, it is necessary to manually open the door and remove the drive that caused the trouble.

Preparatory Operations after Opening the Door, and Related Cautions When the door opens, push the FUNCTION key to switch to System Administrator mode and read out and make a note of various kinds of information upon error generation in Config submode and Info submode.
  • Page 133 DRM-7000, DRM-AF751, DRM-AL751, DRM-AH721, DRM-PW701 Errors in the elevating system After an error is generated in the elevating system, manual operation (Diag-Robotics-Individually-Elevation-Manual in Test mode) is also forbidden, because there is no guarantee that the address will be recognized normally. However, by setting to this mode, you can monitor the change in address using the display window.
  • Page 134 DRM-7000, DRM-AF751, DRM-AL751, DRM-AH721, DRM-PW701 Errors in the loading system The loading motor can be operated manually (Diag-Robotics-Individually-Loading-Manual in Test mode) only if you cancel the operation restriction by pressing the door switch (turning the relay on). Be sure to switch to Test mode first, because initialization (including the elevating system) is started when the door switch is pressed in any mode other than Test mode.
