3.2. Clear signal tracking algorithm software
3.2.1.
Each power up, or after time-out of adjustment mode, automatically matches the emitter power (light source) to
the light receiver, for maximum sensitivity, regardless of dust buildup or other environmental considerations
3.2.1.1. The light bar will turn off and remain off until the process is complete
3.2.1.2. The sensor light source (emitter) will cycle from low to high power and reset at the proper level
3.2.1.3. After approximately 2 seconds the process is complete and the sensor returns to normal.
3.2.1.4. Push-button access - Press and hold (+) push-button for greater than 2 seconds to initiate
3.2.2.
Dynamically regenerates the threshold level every 100ms based on a low-pass filtered clear signal level, to
compensate for dust buildup, etc., between optimization cycles
3.2.3.
Drift Alarm - If the filtered clear signal level degrades (drifts down slowly) to the point that the system may soon
become unreliable, the outputs will alarm (lock on) and remain on until the sensor is cleaned and an optimization
cycle is performed.
3.2.3.1. Light bar LEDs 5 – 8 (upper half) will flash
3.2.4.
Blockage Alarm - If the peak clear signal level is darker than the dark threshold for more than 100ms, the outputs
will alarm (lock on) and remain on until the blockage is removed
3.2.4.1. Light bar LEDs 1 – 4 (lower half) will flash
4.
