Positioning the Modules

The Global Control Module must be mounted at the top of the stack, which places its control
panel at a convenient height. The control panels of the slave modules are of secondary
importance, as they serve mainly to help localize system failures. When installed, the motor
drive assembly of the XpressChannel is directly behind the Global Control Module.
Slave modules may be installed anywhere below the Global Control Module, in any order.
There may be a slight performance advantage in making the slave modules contiguous, but
gaps are permitted. The size of a gap is limited by the fact that each gap must be bridged by
some number of 7" XpressChannel track sections. For safety, available cover plates should be
installed on all XpressChannel sections which are not connected to LibraryXpress modules.
The Global Control Module senses the position of each module during initialization at power-
up. Even if there are gaps between modules, the system will operate correctly. If you plan to
leave gaps between modules, be sure to order additional XpressChannel track segments and
cover plates equal to the length of the gap.

Mechanical Installation

Assembly of the XpressChannel requires experience working with moderately complex
mechanisms, and the ability to follow directions carefully. If you can assemble and adjust a
bicycle with a derailleur mechanism, you probably can assemble and install the
XpressChannel.

Identifying the Parts of the XpressChannel

Locate and identify the XpressChannel internal and external parts. The XpressChannel is
made up of the following external parts, shown in Figure 2-1:
•
Motor drive section (1)
•
Extension sections (2)
•
Elevator base with idler pulley (3)
•
Tie bars (4)
•
Support brace (5)
•
Left and right rack slide extensions (6)
•
Angle brackets (7)
•
L-Shaped Nut Plates (8)
