NG1000 Troubleshooting Manual Mechanical Drawings
Issue 0.4 2010-10-12 Page 5-1
Section 5: Mechanical Drawings
This section contains mechanical drawings for assemblies of the transmitter. Dimensional drawings
may be included. Refer to
Table 5.1 on page 5-2 for an itemized list.
Assembly detail drawings for assemblies and modules that have separate manuals are not included.
Refer to the appropriate maintenance manual for the assembly detail of these assemblies.
Identifying mechanical drawings
Each mechanical drawing in this section is identified by a number that is both the figure number and
the page number. The numbers are assigned sequentially and are prefixed by the letters
MD
.
Drawings in this section are listed in Table 5.1 on page 5-2 .
Content of mechanical drawings
Mechanical drawings are illustrations that depict the location of electrical components and show
assembly outline detail. Dimensional information is included, where appropriate.
When a module or assembly is the subject of its own assembly detail drawing, and it is also shown in
a higher level assembly, the detail depicted in the higher level assembly may have minor differences
from the module or assembly actually installed. In this case, always refer to the assembly detail
drawing of the module or assembly for detailed information.
Locating a part or assembly on a mechanical drawing
1. When a part or assembly is assigned a reference designation (e.g.,
A2A1
or
A2A1R1
), refer to
the family trees in Section 3, “Parts Lists” on page 3-1 . Follow the family tree branches to
the block that contains the desired reference designation and Nautel nomenclature (e.g.,
NAPC157 System Controller PWB
). Note the reference designations and Nautel
nomenclatures of all higher assemblies in the path.
Example:
A1 NAX251 System Controller > A1A1 NAPC157 System Controller PWB
.
2. Refer to Table 5.1 on page 5-2 . Use the reference designation and Nautel nomenclature to
identify the appropriate mechanical drawing.
Example:
NAPC157 System Controller PWB
is shown on schematics
MD- 3
.
