OM-2094 / Operation and Maintenance Manual
Jet-Ex 5D / Series 500285 / Generator Set
This manual contains operation and service information for 28.5 V DC Generator sets identified as Jet-Ex 5D.
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.
Most information in the manual applies to the 28.5 V Jet-Ex 5D in general. Information which applies to
options and special equipment are listed in Appendix A.
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

Engine, Generator and Controls

1.
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, 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).
