Fig. 6.1. Example of alarm limits and break detection.
KPM KB2 alarms if signal goes
above "Cleaning alarm HIGH" = 1000
or
below "Cleaning alarm LOW" = 3
"Drift Alarm" goes on when signal level drops below "Cleaning alarm DRIFT" (here limit = 80
which is 70 % from break (10) to Paper (110). "Detection limit" is set to 60 (50 % value between
paper and break). KPM KB2 informs break whenever signal drops below 60.
