How to Use this Manual
The NJEX-7300L Operations Manual is a step-by-
step guide containing the procedures needed to
work with the 7300L System.
The NJEX System Series of odorizers implement the
most advanced technology available in the industry. It is
recommended that the technicians working with the
NJEX Odorization Systems study the manual prior to
initiating work on the system for the first time.
Typographic Conventions
To aide in readability, this manual uses several
typographic conventions. References to illustrations,
photographs, and other related content will appear in
italicized text along with the location of where to find the
item in the manual. Digital versions of the manual,
available in Adobe Acrobat™ PDF format, will be
highlighted further in
blue italic text indicating the copy
retains a hyperlink to the referenced item.
Measurement units are listed in italic parenthesis text
following their US standard equivalent. As an example,
for defining a distance, 15' (4.5 meters), is how the text
will appear throughout the manual.
Items that require action, for example the pressing of a key
for programming the controller, will feature the action item in
sentence case Bold Text followed in normal text by the
item such as, the Up Arrow key or Main Power switch.
Starting with Section 4, System Control & Electronics,
the manual will begin discussing the in-depth operation
of the N-300 electronic controller where many of these
typographic conventions will be found. In the discussion
about the controller, the technician will learn about the
dual-use keypad. Here, the controller LCD will display a
new function for the key located immediately below the
displayed item. For example, an Up Arrow key may
have *Set immediately above it on the LCD indicating to
set, or enter, the selected item into the memory of the
N-300 controller. The asterisk (*), immediately before
Set on the LCD indicates the dual-use keypad is active.
Further discussion on the dual-use capability of the
N-300 controller keypad will take place in
Section 4,
System Control and Electronics, on page 19.
