b. With your free hand, move the parking tab to the "unparked" position so that it is removed
completely from the interior of the module (Model 1 parking tab: swivel the parking tab away
from you; Model 2 parking tab: move in a clockwise direction). When replaced correctly, the
parking tab will not accidentally swivel into the path of the robot.
c. Gently release the robot assembly. It will lower to the bottom module of the library.
10 Close the library’s I/E station and access doors.
11 Power on the library.
Removing and Replacing the Model 1 Picker Assembly from the
Y-Carriage Assembly Inside the Library
The picker is the robotic device with mechanical “fingers” that open and close to handle data cartridges
inside the library. The picker is housed in the control module, though it can traverse up and down the entire
length of the library.
When the library is powered off, the picker rests in the bottom module of the library, regardless of where the
control module is located.
These instructions describe how to replace the picker with a new one. You may need to replace the picker
if there are problems with the current one.
Follow proper ESD protocol any time you are handling the robot
assembly or any of its components (picker, Y-carriage assembly).
Handle the picker assembly and flex cable gently. Do not crease or
tear the flex cable.
