Alarm Status Screen
Selection of item 3 from the Main Menu presents the Alarm Status Screen, Figure 14. This screen is a composite display of all current alarms for each of the 13 slots. Alarm types are indicated by the number 1 for Critical, 2 for Major, and 3 for Minor alarms.
A capital A indicates the alarm is current while a trailing * indicates the alarm cutoff has been exercised. ES or SES indicates the programmed threshold has been exceeded, resulting in an alarm. The position of the alarm indicator codes in the screen matrix indicates
both the alarm location and slot number.
Alarm History Screen
The Alarm History Summary Screen (Figure 15) can be accessed from the Alarm Status Screen by pressing H. This screen provides a time and date stamp for up to 100 alarm events. These events include alarm initiation and alarm clear. For convenience, a user marker can be invoked by pressing X. This produces a highly visible marking point so that subsequent alarm events can be easily distinguished from older ones.
