5.4 Alarms and their classification
All sensors use function alarms that are enabled when, for example, there is a cable break or short circuit. On
top of this, there are several different types of level alarms; high-level and low-level where the size of the
sensors' level can be limited. These level alarms are filtered with a delay time.
A selection of alarms is displayed in the table below.
