Section 3: Parts Lists
This section contains reference designation lists that provide descriptive and provisioning
information for all electrical and mechanical parts that have an assigned reference designation and
form a part of the XR6/XR3 transmitter.
Family tree
Figure 3.1 on page 3-6 depicts the family tree for an XR6/XR3 with 3-phase ac power. Figure 3.2 on
page 3-7 depicts the family tree for an XR6/XR3 with 1-phase ac power. Figure 3.3 on page 3-8
depicts the family tree for an RF power moduleXR6/XR3. Family trees are based on the descending
order of the reference designation hierarchy. They identify all assemblies that have an assigned Nautel
configuration control number.
How to locate information about a specific part
To locate the information for a specific part, the assigned reference designation for the part must be
known. In addition, the Nautel nomenclature (e.g., NAP34A) assigned to the assembly containing the
part or the full reference designation, including the reference designation of all higher assemblies,
must be known.
When the nautel nomenclature is known:
• Refer to the parts list at the end of this section.
When the reference designation is known:
• Refer to the family tree depicted in Figure 3.1 on page 3-6 (for 3-phase transmitters) or
Figure 3.2 on page 3-7 (for 1-phase transmitters) with the full reference designation.
• Follow the family tree branches to the block that represents the lowest level assembly
assigned a Nautel nomenclature. Then refer to the parts list at the end of this section.
