6.3 Handling Alarms
FCD-E1 maintains an alarm buffer that can store up to 100 alarm messages.
Alarm Display
FCD-E1 displays alarm messages both on the front-panel LCD and on the
supervision terminal. Alarms can be of two types, designated as ON/OFF and ON:
• An ON/OFF-type alarm is displayed only when the alarm condition is present,
and is automatically removed when the condition is cleared (if the alarm is
being displayed, it will disappear only when the display is refreshed by
scrolling).
• An ON-type alarm persists even after the event that caused the alarm
condition is cleared.
