BOS 18Kx-xx- SERIES
INSTRUCTION MANUAL
CONTROLS
OUTPUT LED (BOS 18K…PD/PE/XA/QC/QD/RE/TB/FR/1N1R, BLE
18K..)
The yellow LED ON indicates that the NO output status is closed.
STABILITY LED (BOS 18K...PD/PE/QC/QD/FR, BLE 18K...PP)
The green LED ON indicates that the received signal has a reserve
greater than 30% compared to the output switching value.
POWER ON LED (BLS 18K...1P)
The green LED indicates that the sensor is operating.
POTENTIOMETER (BOS 18K...QD/PD/PE/TB/FR, BLE 18K...PP)
The potentiometer can be used to adjust sensitivity; the operating
distance increases turning the potentiometer clockwise.
WARNING: The potentiometer rotation is limited to 270° by a
mechanical stop.
Do not apply excessive torque when adjusting (max 40 Nmm).
INSTALLATION
The sensor can be fixed by means of the M18x1 threaded body through a
18mm
hole, using the specific washer and the two CH.24 nuts enclosed (1.5Nm maximum
tightening torque).
Alternatively, the sensor can be mounted
through the two housing’s holes using two
screws (M3x22 or longer) and washer.
Amongst the various possible solutions, we
suggest to choose the combination that offers
the best visibility of the signalling LEDs and the
easiest access to the potentiometer.
Wide range of accessories available: 22mm
nuts, h=8mm, (2Nm maximum tightening
torque) guarantee an improved torque and
various orientable fixing brackets ease the
sensor positioning (please refer to the
accessories listed in the general catalogue).
The operating distance is measured from the front surface of the sensor lens.
Only diffuse type: To improve the detection, the object has to be moved closer or further
away from the front surface of the sensor lens.
In case of lateral translation, the object must move as indicated in the figure.
CONNECTIONS
The connections are complaint to the EN 60947-5-2.

SETTING
Setting of BOS 18K...RE
Position the sensor and reflector on opposite sides.
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.
Setting of BOS 18K...QC/QD/TB
Position the sensor and reflector on opposite sides.
Turn the sensitivity potentiometer to the maximum position.
Moving the sensor both vertically and horizontally, determine the power
on and off points of the yellow LED (OUT) and then mount the sensor in
the middle of the points defined. Optimum operation is obtained when
the green LED (only BOS 18K...QC/QD) is ON and the yellow LED is
OFF.
QC/QD
If necessary reduce sensitivity in order to detect
very small targets. In order to improve alignment, repeat
the procedure detailed above whilst progressively
reducing the sensitivity.
TB
Turn the sensitivity trimmer counterclockwise until the yellow LED
turns ON (pos.A). Turn slowly the trimmer again clockwise until the
yellow LED turns OFF (Operating condition, pos.B).
Setting of BLE/BLS 18K.../BOS 18…FR (with P/R fibre optics)
Position the sensors on opposite sides.
Turn the sensitivity potentiometer to maximum: moving the sensor both
vertically and horizontally, determine the power on and off points of the
yellow LED (OUT) and then mount the sensor in the middle of the points
defined. Optimum operation is obtained when the green LED is ON and
the yellow LED is OFF.
If necessary, reduce sensitivity using the potentiometer, in order to
detect very small targets. In order to improve alignment, repeat the
procedure detailed above whilst progressively reducing the sensitivity.
Setting of BOS 18K...PD/PE/FR with proximity fibre
Turn the sensitivity potentiometer to minimum: the green LED is ON, the
yellow LED is OFF. Position the target to detect in front of the sensor or
of the fibre terminals. Turn the sensitivity potentiometer clockwise until
the yellow LED turns ON
(Target detected state, pos.A).
Remove the target, the yellow LED turns OFF.
Turn the sensitivity potentiometer clockwise until the yellow LED turns
ON
(Background detected state, pos.B).
The potentiometer reaches maximum if the background is not detected.
Turn the potentiometer to the intermediate position C, between the two
positions A and B. The green LED must be ON.
Setting of BOS 18K...XA/1N1R
The operating distance range of these sensors is fix. Please consider
this feature when positioning.
TEST FUNCTION (BLS)
The TEST+ and TEST- inputs can be used to inhibit the emitter and
verify that the system is correctly operating.
The receiver output should switch when the test is activated while the
beam is uninterrupted.
The inputs activating voltage range is 10 … 30 Vdc.
