You may have more than one alarm condition at the same time. For multiple alarms, the Alarm
Indicator ( ) will display the most severe alarm and the alarm will sound the most severe alarm. As
mentioned previously, when an alarm occurs, two lines of words appear on the Controller Display.
The first line tells you what the alarm is, and the second line tells you what to do. An arrow () is
displayed on the right side of the alarm if there is more than one alarm (Figure 15).
