Fig. 6.1. Example of alarm limits and break detection.
KB alarms if signal goes above "Cleaning alarm HIGH" or below "Cleaning alarm LOW". "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). KB informs break whenever signal drops below 60.
