Fail Sensor protection (when activated) does not affect the function of the system itself. If you adjust
“Active when” to Under limit + Fls or Over limit + Fls the protection will considered the value that is out
of range (failed sensor) to be under or over limit (depending on the setting) and it will issue
corresponding alarm after the delay of the protection. This can be used for example when the function
of the particular sensor connected to an analog input is crucial for the operation of the system and its
failure requires the system to be affected (open breakers etc.).
