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 110.
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 111.
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 112.
Further discussion of the display functions can be found
under the
Setting & Testing Alarms, Section 9 beginning
with page 53.
