This page (Figure 2.5) shows the status of the different alarms. The information shown corresponds to the
last time the page was refreshed.
Each alarm can be in two states:
Green: The alarm is not activated
∗
Red: The alarm is activated
∗
The alarms shown on this page are in turn grouped into 4 blocks. Each of these blocks can be in two different
states:
Green: All the alarms in the block are inactive
∗

∗
In point 4.2 Alarm Scenarios of the appendix, different examples are shown depending on the active
