Display Functionality
Characters in the display will change to indicate the
varying conditions of NJEX System operation. As
discussed in the
Introduction, Section 1
and in
Section 4
System Control and Electronics,
the display interacts
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 Indicators.
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 beginning
with page 53.
