104 AFP-3030 Programming Manual — P/N DOC-01-032:A 26/06/2015Intelligent Sensing Applications Intelligent Sensing FeaturesA graphic representation of a detector analog reading using drift compensation and smoothing:Figure C.1 Graphic Representation of Drift CompensationC.2.2 Maintenance Warnings – Three LevelsThe software determines when the drift compensation for a detector reaches an unacceptable levelthat can compromise detector performance. When a detector reaches an unacceptable level, thecontrol panel indicates a maintenance warning. The table below summarizes the three levels ofIntelligent Sensing maintenance warnings:Table C.1 Definitions of Intelligent Sensing Maintenance LevelsA graphic representation of the maintenance levels:Figure C.2 Diagram of Maintenance LevelsAwacs1a.cdrAnalogReadingAlarm Levelwith compensation andsmoothingwithout compensationTimeDetector FaultMessage IndicatesDetector Compensation Percentage RangeIon Photo orPhoto with HeatLaserN/A Compensation is within acceptable range. 6 - 80 6 - 45 3 - 50LOW THRESHOLD A hardware problem in the detector. 0 - 5 0 - 5 0 - 2MAINTENANCE REQ Dust accumulation that is near but belowthe allowed limit.
