S8-PR/MR...U
Luminescence 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
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 holes using 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 catalogue).
The operating distance is measured from
the front surface of the sensor optics.

SETTINGS
LIGHT/DARK MODE SETTING
LIGHT mode setting
Rotate trimmer in an anti-clockwise direction to set the LIGHT
mode (output ON on fluorescent mark).
DARK mode setting
Rotate trimmer in a clockwise direction to set the DARK mode
(output ON on background).
EASY TOUCH ACQUISITION
Place mark in front of the sensor spot and press
SET until the green READY LED turns off.
If the READY LED turns permanently ON the
acquisition was successful.
If the LED blinks slowly the acquisition failed due
S8-MR
to insufficient signal.
Press SET and the sensor returns to the previous
setting.
If the Easy Touch acquisition fails due to
insufficient signal, try using Mark-Background
procedure described below.
MARK-BACKGROUND ACQUISITION
Mark acquisition
Place mark in front of the sensor spot and press
SET until the green READY LED turns on again
(3 sec).
Background acquisition
Place background in front of the sensor spot and
press SET again.
If the READY LED turns permanently ON the
acquisition was successful.
If the LED blinks slowly the acquisition failed due
to insufficient contrast.
Press SET and the sensor returns to the previous
setting.
During detection if the luminescence is very low, the sensor increase his
sensitivity with a frequency of 500Hz ( LED READY green blinks two times at
the end of teach procedure).
