Contrast sensor
INSTRUCTION MANUAL
CONTROLS
OUTPUT LED (yellow)
The yellow LED ON indicates the output status.
READY LED (green)
The green LED ON indicates the powering status.
SET PUSH-BUTTON
A long pressure on the push-button activates the teach procedure.
The REMOTE input allows the external control of the SET push-button.
DARK/LIGHT TRIMMER (only for dynamic setting)
The light/dark mode is selected by a monoturn trimmer.
Please refer to the "SETTING" paragraph to get the correct setting procedure.
WARNING: the maximum mechanical rotation range of the trimmer is 240°.
Do not force over of the maximum and minimum positions.
INSTALLATION
S8-PR:
The sensor can be positioned by means of the two housing
holes using two screws (M3x18 or longer, 0.8Nm maximum
tightening torque) with washers.
S8-MR:
The sensor can be positioned by means of the
two threaded holesusing two screws (M3x14 or
longer, 0.8Nm maximum tightening torque) with
washers.
Various orientable fixing brackets to ease the
sensor positioning are available (please refer
to the accessories listed in the general
S8-PR
catalogue).
The operating distance is measured from the front surface of the sensor
optics.
Mark detection on a reflective surface is improved
adjusting the beam direction to 5° ... 20° from
surface axis.

SETTINGS
MARK-BACKGROUND ACQUISITION
Mark acquisition
The DARK/LIGHT mode is automatically
selected by the sensor.
Place mark in front of the sensor spot and
press SET push-button until the green READY
LED turns off (1 sec).
The sensor functions alternating red, green and
blue emissions.
Do not move the mark during this phase.
S8-MR
Background acquisition
Place background in front of the sensor spot
and press SET push-button again.
The sensor functions alternating red, green and
blue emissions.
Do not move the mark during this phase.
DYNAMIC ACQUISITION
Use the dynamic setting to detect moving
target. The sensor sets automatically the
threshold value during target movement. The DARK/LIGHT mode has to
be previously set.
LIGHT/DARK MODE SETTING
LIGHT mode setting
Rotate trimmer in an anti-clockwise direction to set the
LIGHT mode (clear mark on dark background).
DARK mode setting
Rotate trimmer in a clockwise direction to set the DARK
mode mode (dark mark on clear background).
Dynamic detection
Position the sensor spot in front of the target to detect.
Press SET push-button until the green READY LED turns off (3sec) and keep it pressed.
To end the dynamic detection procedure release the SET push-button.
The sensor functions alternating red, green and blue emissions.
SETTING RESULT
The switching threshold is typically placed 25% below the mark. If the sensing conditions are accepted, at the end of teach procedure the READY LED
blinks x2 for 3sec. If SET push-button is pressed in this 3 seconds the switching threshold is placed in the midpoint between the mark and the background.
If the READY LED blinks fast the acquisition failed for to insufficient contrast.Press SET push-button and the sensor returns to the previous setting

OTHER FUNCTIONS
KEYLOCK function (keyboard lock)
The KEYLOCK function (keyboard lock) allows to deactivate the SET
push-button avoiding accidental changes in the sensor setting.
If at sensor powering the REMOTE wire is connected to +Vdc for at least 1
sec., the keylock function is activated and the push-button is no longer
active.
To deactivate the keylock, the sensor must be turned off and repowered
with the REMOTE wire not connected or connected to GND.
REMOTE input
Different detection functions can be made with the REMOTE signal,
without using the SET push-button.
The REMOTE wire connected to +VDC is equal to pressing the SET push-
button, it connected to GND or not connected is equal to not pressing the
SET push-button.
The connection duration of the REMOTE wire to +VDC determines the
detected type requested:
