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.
