Guide to Using Har ris Parts List Information

t

The Harris Replaceable Parts List Index portrays a tree structure with the major items being leftmost in the index. The
example below shows the Transmitter as the highest item in the tree structure. If you were to look at the bill of materials
table for the Transmitter you would find the Control Cabinet, the PA Cabinet, and the Output Cabinet. In the Replaceable
Parts List Index the Control C abinet, PA Cabinet, and Output Cabinet show up one i ndentation level b elow the T r ansmitter
and implies that they are used in the Transmitter. The Controller Board is indented one level below the Control Cabinet so
it will show up in the bill of material for the Control Cabinet. The tree structure of this same index is shown to the right of
the table and shows indentation level versus tree structure level.

Example of Replaceable Parts List Index and equivalent tree structure:

Replaceable Parts List Index Part Number Page

Table 7-1. Transmitter 994 9283 001 7-2
Table 7-2. Control Cabinet 992 9244 002 7-3
Table 7-3. Controller Board 992 8344 002 7-6
Table 7-4. PA Cabinet 992 9400 002 7-7
Table 7-5. PA Amplifier 994 7894 002 7-9
Table 7-6. PA Amplifier Board 992 7904 002 7-10
Table 7-7. Output Cabinet 992 9450 001 7-12

The part number of the item is shown to the right of the description as is the page in the manual where the bill for that part
number starts. Inside the actual tables, four main headings are used:

Control Cabinet
992 9244 002

Controller Board
992 8344 002

Transmitter
994 9283 001

PA Cabinet
992 9400 002

PA Amplifier
992 7894 002

PA Amplifier Board
992 7904 002

Output Cabine
992 9450 001

• Table #-#. ITEM NAME - HARRIS PART NUMBER - this line gives the information that corresponds to the

• Replaceable Parts List Index entry;

• HARRIS P/N column gives the ten DIGIT Harris part number (usually in ascending order);

• DESCRIPTION column gives a 25 character or less description of the part number;

• REF. SYMBOLS/EXPLANATIONS column 1) gives the reference designators for the item (i.e., C001, R102,

etc.) that corresponds to the number found in the schematics (C001 in a bill of material is equivalent to C1 on the
schematic) or 2) gives added information or further explanation (i.e., “Used for 208V operation only,” or “Used
for HT 10LS only,” etc.).

Inside the individual tables some standard conventions are used:

• A # symbol in front of a component such as #C001 under the REF. SYMBOLS/EXPLANATIONS column

means that this item is used on or with C001 and is not the actual part number for C001.

• In the ten digit part numbers , if the last th ree numbers are 000, t he item is a part that Harris has pu rchased and has

not manufactured or modified. If the last three numbers are other than 000, the item is either manufactured by
Harris or is purchased from a vendor and modified for use in the Harris product.

• The first three digits of the ten DIGIT part number tell which family the part number belongs to - for example, all

electrolytic (can) capacitors will be in the same family (524 xxxx 000). If an electrolytic (can) capacitor is found
to have a 9xx xxxx xxx part number (a number outside of the normal family of numbers), it has probably been
modified in some manner at the Harris factory and will therefore show up farther down into the individual parts
list (because each table is normally sorted in ascending order). Most Harris made or modified assemblies will
have 9xx xxxx xxx numbers associated with them.

The term “SEE HIGHER LEVEL BILL” in th e d escript ion column imp lies that the reference designated part number will

show up in a bill that is higher in the tree structure. This is often the case for components that may be
frequency determinant or voltage determinant and are called out in a higher level bill structure that is more
customer dependent than the bill at a lower level.
