3.1.1 Detailed Calibration Method of Omron Type Photocells
The proper operation of the PNG gate requires the correct alignment of the photocells: the infrared beam
must be as best as possible centered on the corresponding reflector/receiving photocell. Moreover, their
sensitivity must be correctly adjusted, so as to ensure an optimal detection level.
The lens of the cell must be kept clean. All optical systems being influenced by the environment in which
they are situated, the presence of haze, mist, smoke, fumes, dust, etc. may affect their operation by
reducing the sensing distance. Use domestic type of window cleaner (“Windex”) when cleaning the lens.
Each photocell comprises 2 potentiometers and 2 LED, a green and an orange
(see figure A)
. Green LED
shows the photocell stability, orange LED shows the photocell output level
(ON/OFF)
. Sensitivity
potentiometer will set photocell detection level; operation selector will set the output level of the photocell.
