Message text and description Details and solution
2014 Bottom cover is missing. If the base module cannot detect both a top and
bottom cover, the robotic mechanism will not
move.
1. Install the bottom cover on the bottom
module in the library.
2. Check the module interconnect cabling and
module power cords.
2015 Top cover is missing If the base module cannot detect both a top and
bottom cover, the robotic mechanism will not
move.
1. Install the top cover on the top module in the
library.
2. Check the module interconnect cabling and
module power cords.
2016 Module alignment mechanism is not
locked properly.
Ensure that the alignment mechanisms for all
modules above the bottom module are engaged
and locked.
2017 A communication problem between
modules was detected.
1. Ensure that all modules are powered on.
2. Ensure that all module interconnect cables
are properly attached.
3. Ensure that the alignment mechanisms for
all modules above the bottom module are
engaged and locked.
2018 Too many unit position transmitter or
detector failures.
1. Ensure that the alignment mechanisms for
all modules above the bottom module are
engaged and locked.
2. Power cycle the library.
2021 Database access error. If this event is seen on 4.90 or later firmware
versions:
1. Reboot the library.
2. If the error persists, restore the library
configuration. See Restoring the library
configuration from a file on page 57.
