Страница: 7 / 142

Introduction
This manual contains operation and service information for 28.5 V DC Generator sets identified as
Jet-Ex 4D. These units are available as stationary, skid- mounted units, or they may be trailer-mounted for
portability. Both versions are available with 14 V DC output capability.
The primary purpose of the manual is to provide information and instructions to experienced operators,
electricians, and mechanics who are not familiar with this equipment. The intent of the manual is to guide
and assist operators and maintenance personnel in the proper use and care of the equipment.
Read the instructions before starting the unit. Learn to use the manual and to locate information contained in
it.
The Table of Contents, which follows this Introduction, lists all Chapters, Sections, and the paragraph titles
within each Section. The location of each listing is identified by Chapter, Section and page number.
Each Chapter is divided into as many Sections as necessary. Sections are always referred to by a
combination Chapter-Section number, for example: 2-3 refers to Chapter 2, Section 3.
The material within each Section is divided into main subjects with applicable paragraph headings and
sub-headings as required. For example, a portion of the Description Section might logically follow this
arrangement and paragraphing:
Section 1. Description
1. Engine, Generator and Controls
a. Interior Panel
(1) Protective devices
a. Overload relay
(2)
Contactors
Page numbers do not run consecutively throughout the manual. Each page is identified by the Chapter-
Section number in which it appears, and by a page number within the Chapter-Section. Therefore, the first
page in each Section is page 1. These identifying numbers appear in the lower, outside corner of each page.
Each page also bears a date located in the corner opposite the page number. This date is either that of
original issue, or of the latest revision. Any revision to the original text is identified by a heavy black line in the
left-hand margin. Illustrations follow a numbering system similar to page numbering. The first Figure in each
Section is Figure 1.
All tables, charts and diagrams, as well as illustrations, are identified by Figure numbers to avoid confusion.
The general location of any particular information can be found quickly by running through the Table of
Contents. For example: to locate any adjustment information, a quick look at the Table of Contents shows that
“Adjustment / Test” is located in Chapter 2, Section 3,
(shown as 2-3) .
Portions of the text are referred to by identifying the paragraph in which the referenced material may be found.
When referenced material is located in the same Chapter/Section as the reference, only the paragraph
identification is given, for example:
(Ref. Para. 1, A)
means that the material is to be found in paragraph 1, A,
of the same Section.
