Then...
1. Visually verify that all gear racks (front and rear) are
properly aligned. If they are not aligned, refer to
"Verifying Front and Rear Gear Racks Alignment" on page
8-22.
2. Ensure the Y-axis Assembly is level from front to back. If a
gear rack gap was discovered, or if the Y-axis Assembly
was previously removed and replaced, one side may be off
by one or two teeth. With the top cover removed, and
power OFF, slowly lift the Y-axis Assembly and re-insert
(see "M2 Robot Assembly" on page 8-67).
3. Check for broken gear teeth on the Y motor. If there are
broken teeth, replace the Y-Axis Assembly.
1. Check cable connections from the Cable Spool to the Y-axis
Assembly and from the Y-axis Assembly to the Picker.
2. With Access Doors closed, note if the green LED on top of
the Picker is ON.
v For a 5U library, open the I/O Station door to view.
v For a 14U library or larger, look through the expansion
module window.
3. If the green LED is OFF, suspect the Picker Assembly, the
Y-axis Assembly, the module-to-module communication
terminator, or an open door.
4. If the Picker Assembly is still not working, contact your
next level of support.
v Ensure both front and rear gear racks on all modules above
the bottom-most module on a multiple module unit (such
as a 14U library) are in the lock-down position. Gear racks
between modules must not have a gap between them;
otherwise, the Y-axis Assembly will no longer be level.
v Ensure the Y-axis Assembly is level from front to back. If a
gear rack gap was discovered, or if the Y-axis Assembly was
previously removed and replaced, one side may be off by
one or two teeth. With the top cover removed, and power
OFF, slowly lift the Y-axis Assembly and re-insert (see "M2
Robot Assembly" on page 8-67).
v Ensure that the Y-axis motor is properly inserted in the
opening in the base plate .
