OUTPUT LED (yellow) (S8…B/C/M/F)
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.
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 “SETTING” paragraph for the correct use procedure.
SENSITIVITY TRIMMER (ADJ.) (S8..B/C/F)
The sensitivity and operating distance can be adjusted using this trimmer.
See the “SETTING” paragraph for procedure indications.
LIGHT/DARK TRIMMER
The light/dark mode is selected using a mono-turn trimmer.
Please refer to “SETTING” paragraph for the correct use procedure.
WARNING:
the maximum mechanical rotation range of the 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, 0.8Nm 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
DARK/LIGHT SETTING
Rotate trimmer in an anti-clockwise direction to set the LIGHT mode
(output ON with the reflector).
Rotate trimmer in a clockwise direction to set the DARK mode
(output ON in presence of the object).
SUPPRESSION DISTANCE SETTING (S8...M)
1.
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
2.
Background suppression
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).
3. 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.
SENSITIVITY SETTING (S8...B)
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).
SETTINGS (S8...C)
Turn the sensitivity trimmer to minimum: the yellow LED is OFF (light mode).
Position the target to detect in front of the sensor.
Turn the sensitivity trimmer clockwise until the yellow LED turns ON
(Target
detected state, pos.A).
Remove the target, the yellow LED turns OFF.
Turn the sensitivity trimmer clockwise until the yellow LED turns ON
(Background
detected state, pos.B).
The trimmer reaches maximum if the background is not detected.
Turn the trimmer to the intermediate position C, between the two positions A and B.
MIN
MAX

C
SETTINGS (S8...F/G)
Position the sensors on opposite sides. Turn the sensitivity trimmer to maximum. Find
the points where the yellow LED (OUT) is switched ON and OFF in both vertical and
horizontal positions, and fix the sensor in the centre between these points. If necessary,
reduce sensitivity using the trimmer, in order to detect very small targets. In order to
improve alignment, repeat the procedure detailed above whilst progressively reducing
the sensitivity.

DIAGNOSTIC FUNCTIONS (S8…G)
TEST+ input
The TEST+ input can be used to inhibit the emitter and verify that the system is
correctly operating. The TEST function is activated if the TEST+ input is connected
to a voltage between 12…30V, whereas if the TEST+ input is connected to GND or
it is not connected the function is disactivated.
The sensors are NOT safety devices, and so MUST NOT be used in the safety control of the machines
where installed.
