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.).
