Monitoring Screens
The EA800 user interface is menu-based. During normal system monitoring, one of the following three screens is
displayed depending on the current state of the programmed sensors:
The
MONITORING (home) screen is displayed
when there are no active alarms. The screen lists
all programmed sensors connected to the base
unit and their current reading or state.
The
MONITORING (home) screen displays pending
alarms in reverse video as shown in the example
at right (71° exceeds the temperature limit for
Sensor 2, so it is shown as light text on black).
Pending alarms indicate that the programmed lim-
its for the sensor have been exceeded, but the
sensor’s programmed delay time has not elapsed
yet. If the monitored conditions continue to
exceed the programmed limits for longer than the
programmed delay period, the pending alarm will
become an active alarm.
The
ACTIVE ALARMS screen is shown when one or
more sensors are in an active alarm or warning
state. If more than one alarm is active, each will
be listed on the screen. In the example shown,
Walk-in Cooler and Warehouse alarms are
occurring simultaneously.
