10.4.2 Alarm Status
This group of pictures allow the operator to read the current alarm status. Alarms can
be generated based on measurement data from all relevant sensors, i.e. depending on
the selected application, there are a number of Alarm Status pictures. There is an
Alarm Status picture for every sensor that has an alarm setup, as explained on page
66. Figure 8 explains the different alarm status values and their relation to the alarm
limits that are specified in the Alarm Setup pictures.
Alarm status: Min range Low limit Normal High limit Max range
