b From the back of the library, find the rear Y-rail release
mechanism, which is located in the interior of the right side of the
module. Squeeze the handle of the Y-rail release mechanism, lift
it out of its locked position, and slide it downward as far as it will
go.
Doing this aligns the Y-rails with the Y-rails of the module
beneath it.
9 Unpark the robot assembly.
a Gently raise the robot assembly so that it no longer rests on the
parking tab.
b With your free hand, move the parking tab in a clockwise
direction until it stops in the “unparked” position. When in the
correct position, the parking tab is removed completely from the
interior of the module and will not accidentally swing into the
path of the robot.
c Gently release the robot assembly. It will lower to the bottom
module of the library.
Caution: Check to make sure that there is no gap between the
top and bottom Y-rails on both the front and back of
the library. If a gap exists, the library cannot
mechanically initialize.
Caution: Support the robot assembly by holding onto the broad
metal X-axis plate. Lifting the robot by the thin metal
rod will bend the rod. Lifting the robot by the black
plastic picker body can damage the robot.
