SUPPRESSION DISTANCE AND BACKGROUND ACQUISI-
TION SETTING
The S8-PH…M53 sensor which provides background suppres-
sion for shiny objects, enables the detection of clear objects
without false or multiple triggering typical of other background
suppression sensors. To function correctly it is necessary to
perform the Background Acquisition Setting procedure described
below.
1.Start Setting and Background Acquisition
Rotate the TEACH-IN trimmer fully counter-clockwise. If the
trimmer is already in the counter-clockwise position, rotate it to
the clockwise position and then back to the counter-clockwise
position. The N.O. Output signal (black wire) is set to OFF and
the yellow LED indicates the status in the same way as a stan-
dard background suppression sensor.
2.Background Exclusion
Position the sensor in front of the background. Rotate the
DISTANCE ADJUSTMENT trimmer clockwise until the yellow
LED turns ON: condition where background is detected.
Rotate counter-clockwise the trimmer until the yellow LED turns
OFF: condition where background is out of the field of view.
3.Background Acquisition
Rotate the TEACH-IN trimmer fully clockwise. The sensor
acquires the background characteristics and is ready to detect
any object that passes in the Detection Area. If the yellow LED
blinks, the background acquisition procedure has failed. Rotate
the TEACH-IN trimmer fully counter-clockwise and repeat the
procedure from step 2.
BACKGROUND AUTO-ADJUSTMENT FUNCTION
The sensor provides a background auto-adjustment function.
If the background deteriorates and the received signal chan-
ges, after one minute the sensor automatically adjusts the
background to compensate for this change therefore avoiding
the need to continually acquire the background through manual
setting.
