Section 8: Working with the N-300 System Displays
Display Functionality
Characters in the display will change to indicate the
varying conditions of NJEX System operation. As
discussed in
Section 1: First Things to Know, Typo-
and in
Control and Electronics, page 19
the display inter-
acts with the keyboard to access the different levels
or areas in the programming function of the N-300
controller.
That extra-functionality in the display plays a further roll
in the case of Alarm Indicators and Non-Alarm Indica-
tors.
With the activation of an alarm indicator, the alarm
function of the NJEX System turns into an
UPPER
CASE
character set. For example,
pmp
– pump,
becomes
PMP
indicating that an alarm is active,
figure
114
.
To indicate the specific activity of the alarm, the N-300
will flash a description, and solid black box – , in the
top line of the display,
figure 115
.
The character change indicating that a monitored
condition is in alarm status is further accompanied by
a flashing LED light. Any time an alarm is simulated
or real, a bright red LED light will flash in the alarm
light indicator, located just below the
Select / Enter
key. Any time a non-alarm is simulated or real, a bright
green LED light will flash in the indicator light indicator
,located just below the
Down Arrow
key,
figure 116
.
Further discussion of the display functions can be
found under the
Setting & Testing Alarms, Section 9
