5411.13 ECO Patrol Operation• A Pyoelectric infrared sensor is used to detect injection strength variation of infrared at setting area to determinethe presence or absence of human and its activity level. Human detection area is shown in figure below:• ECO Patrol operation – Human presence/absence detection outlined flowProcess infrared sensor output signalHuman detection (movement) every 3 seconds.Human detection recordsRecords human detection (movement) result for 30 seconds and determine its activity level i.e. Hi/Lo.Presence / absence detectionCompares current and previous human detection result every 30 seconds to determine the presenceor absence of human.Presence / absence determinationBased on human presence / absence detection, if human presence detection showed within 30minutes, it is recognised that human is present. If human absence detection showed continuously formore than 30 minutes, it is recognised that no human is present.• ECO Patrol Sensor abnormality detection(1) Connnector pulled out (disconnected), Wire cut Abnormality (Fix Output at Hi)a) Abnormal judgment start condition.Start from ECO Patrol Sensor power ON, and end after 30 seconds.b) Control content.Judge ECO Patrol Sensor power level every 100ms.c) Abnormal Judgment condition.When ECO Patrol Sensor has continues for 25 seconds Hi level.(2) Circuit Abnormal (Fix Output Lo)a) Abnormal judgment start condition.After ECO Patrol Sensor unit power ON, and after pressed 70 seconds.b) Control content.Judge ECO Patrol Sensor power level every 100ms.c) Abnormal Judgment condition.When ECO Patrol Sensor has continues at Lo level for 25 seconds.(3) Abnormal treatmentAny one of the above self-diagnosis result is abnormal Abnormal counter +1 and ECO Patrol Sensor power supply OFF. After ECO Patrol Sensor unit power is OFF for 5 seconds, Retry the ECO Patrol operation. When Abnormal counter reach 4 counts, ECO Patrol sensor abnormality is confirmed.(Abnormal counter is cleared when sensor power ON and maintain normal for 120 seconds and above orClear Anormal counter by power reset) Save ECO Patrol Sensor Abnormality H59 (no Timer LED blinking). ECO Patrol Sensor operation OFF, but ECO Patrol LED maintain ON. The unit still operate as normal.
