LED DI USCITA (giallo)
Il LED giallo acceso indica lo stato dell’uscita.
OUTPUT LED (yellow)
The yellow LED ON indicates the output status.
POWER ON LED (green)
The green LED ON indicates the powering status and the laser emission
presence.
SENSITIVITY TRIMMER (ADJ.) (S8…B)
The sensitivity and operating distance can be adjusted using this trimmer.
See the “SETTING” paragraph for procedure indications.
DISTANCE ADJUSTMENT TRIMMER (ADJ.) (S8…M)
The multiturn trimmer with clutch (8 turns) adjusts the suppression distance
through the mechanical variation of the optic triangulation angle.
The operating distance increases rotating the trimmer in a clockwise direction.
Please refer to the “SETTING” paragraph for the correct procedure.
LIGHT/DARK TRIMMER
The light/dark mode can be selected using this mono-turn trimmer.
See the “SETTING” paragraph for procedure indications.
WARNING: the maximum mechanical rotation range of the TEACH-IN
trimmer is 240°. Do not force over of the maximum and minimum positions.
INSTALLATION
The sensor can be positioned by means of the two housing
holes using two screws (M3x18 or longer, 0.8 Nm maximum
tightening torque) with washers.
Several fixing brackets are available which can be oriented in
various positions to ease the sensor installation, (please refer
to the accessories listed in the general catalogue).
The operating distance is measured from the front surface of
the sensor optics.

S8…B SETTINGS
DARK/LIGHT MODE SETTING
LIGHT mode: Rotate trimmer in an anti-clockwise.
DARK mode: Rotate trimmer in a clockwise.
SENSITIVITY SETTING
Alignment
: Position and align the sensor and reflector
on opposite side at the desired distance.
Rotate sensitivity adjustment trimmer (ADJ.) to
maximum point (clockwise direction).
Move the sensor vertically and horizontally to
determine the powering on and powering off points of
the yellow LED (OUT) and fix the sensor in the middle
of these two points. To detect very small objects,
reduce the sensitivity using the specific trimmer (
if
necessary
). Repeat procedure reducing progressively
the sensitivity to improve alignment.
Control
:
Enter object laterally in the detection area and check that
the yellow LED turns ON (in dark mode).Remove object and
check that the yellow LED turns OFF immediately (in dark
mode).
ALARM OUTPUT
The alarm output is active (ON) when the received signal remains without safety
margin for more than 1 second (30% respect to output switching value).

DARK/LIGHT MODE SETTING
LIGHT mode: Rotate trimmer in an anti-clockwise.
DARK mode: Rotate trimmer in a clockwise.
SUPPRESSION DISTANCE SETTING
Object detection (LIGHT mode): Position object to detect in front of the
sensor at the distance required.
Turn distance adjustment trimmer (ADJ) to minimum: yellow LED OFF.
Rotate trimmer in a clockwise direction until the yellow LED turns ON:
Object detection condition (pos.A).
pos.A pos.B
pos.C
Background detection:
Remove object and ensure that the background is
in front of the sensor: yellow LED OFF.
Rotate trimmer in a clockwise direction until the yellow LED turns ON:
background detection condition
(pos.B).
The trimmer reaches maximum level with yellow LED OFF if the
background is outside the operating range.
Rotate trimmer in an anticlockwise direction until yellow LED turns OFF:
condition where background is outside operating range
(pos.C).
Setting and control:
Rotate trimmer in an anti-clockwise direction until the
trimmer reaches an intermediate point between position A and C.
If position A and C are close to each other, leave trimmer on position C.
The sensor is now ready to function correctly and in stable conditions.
DELAY SETTING
The DELAY extends to 20ms the minimum duration of the output activation
allowing even slower interfacing systems to detect shorter pulses.
Delay activation
Connect Delay signal (white wire) to power supply.
Delay de-activation
Connect Delay signal (white wire) to 0V or leave it disconnected.

SAFETY PRECAUTIONS
All the safety electrical and mechanical regulations and laws have to be
respected during sensor functioning.
The sensor has to be protected against mechanical damages.
Place the given labels in a visible position close to the laser emission.
The sensors are NOT safety devices, and so MUST NOT be used in the
safety control of the machines where installed.
