S8 IO-Link
Instruction Manual
CONTROLS
OUTPUT LED (yellow)
The yellow LED indicates the output status.
READY LED (green)
The green LED ON indicates normal functioning.
SET PUSH-BUTTON
The acquisition procedure is activated by pressing the SET push-button. The control obtained
with the SET push-button can be made externally with the REMOTE input. Set Pin 2 as
REMOTE through IO-Link.
DELAY TRIMMER (W03)
The digital output’s delay is selected/deselected by a monoturn trimmer.
LIGHT/DARK TRIMMER (T53, B53, U03)
The light/dark mode is selected by a monoturn trimmer.
Please refer to “Settings” for the correct use procedures.
INSTALLATION
The sensor can be positioned by means of the two housing
holes using two screws (M3X18 or longer, 0.8Nm max.
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).
CONNECTIONS
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.
CAUTION: the max. mechanical rotation range of the trimmer
is 240°. Do not force over of the maximum and minimum
positions.

FINE ACQUISITION
Mark detection
The Light/Dark mode is automatically selected by the sensor.
Place the mark in front of the sensor spot and press the SET
button until the READY LED turns off or send the IO-Link Standard
command “SP1 Teach TP1”.
The sensor functions alternating red, green and blue emissions.
Do not move the mark during this phase.
Background detection
Place the background in front of the sensor spot and press the SET
button again or send the IO-Link Standard command “SP1 Teach
TP2”.
The sensor functions alternating red, green and blue emissions.
Do not move the background during this phase.
DYNAMIC ACQUISITION
Use dynamic acquisition to acquire moving marks. The sensor
detects the contrast between the mark and the moving background,
and automatically sets the threshold value. Place the sensor spot
in front of the target to be detected. Press the SET button until the
READY LED lights up again (3 s) or send the IO-Link Standard
command “Teach Dynamic”. To end the acquisition press the SET
button or send the IO-Link Standard command “Teach Dynamic End”.
The sensor functions alternating red, green and blue emissions.
If the READY LED turns permanently ON the acquisition was successful. If the READY LED
blinks quickly the acquisition failed due to insufficient contrast. Press the SET button and the
sensor returns to the previous setting. Repeat procedure from the beginning. Teach-in status
can be read on IO-Link parameter “TI Result”.
LIGHT/DARK SWITCHING (W03)
Pressing the SET button for 5 s inverts the Light/Dark mode. Alternatively, the “SSC1/SSC2
Config” IO-Link parameters can be used.
PNP SETTING
Press the SET button for 10 s to reset Pin 4 in PNP mode. Use this feature if Pin 4 is set in
NPN mode and the sensor must be connected again to an IO-Link master.
DELAY SETTING
Delay activation
Rotate the trimmer counterclockwise.
Delay deactivation
Rotate the trimmer clockwise.
EASY TOUCH ACQUISITION
Place the mark in front of the sensor spot and press the SET button until the READY LED
turns off. If the READY LED turns permanently ON the acquisition was successful. If the
READY LED blinks quickly the acquisition failed due to insufficient contrast.
Press the SET button and the sensor returns to the previous setting. Alternatively, use the IO-
Link Standard command “SP1 Single Value Teach” for Easy Touch Acquisition.
If the Easy Touch acquisition fails due to insufficient contrast, try again using the Mark-
Background Acquisition described below.
MARK-BACKGROUND ACQUISITION
Mark Acquisition
Place the mark in front of the sensor spot and press the SET button until the READY LED
turns back on (3 s).
Background Acquisition
Place the background in front of the sensor spot and press the SET button again. If the
READY LED turns permanently ON the acquisition was successful. If the READY LED blinks
quickly the acquisition failed due to insufficient contrast. Press the SET button and the sensor
returns to the previous setting.
Alternatively, use IO-Link Standard command “SP1 Teach TP1” for Mark Acquisition and “SP1
Teach TP2” for Background Acquisition.
MAX. SENSITIVITY SETTING
To set the maximum sensitivity, press the SET button for 5 s until the READY LED turns off
again. Alternatively, use the IO-Link Standard command “Max. Sensitivity”.
PNP SETTING
Press the button for 10 s to reset Pin 4 in PNP mode.
U03 Models
B53 / T53 Models
SENSITIVITY SETTING
Sensitivity allignment and setting:
•
Place the sensor and the reflector on opposite sides at the desired distance and aligned.
Set the maximum sensitivity for easier alignment.
•
Move the sensor vertically and horizontally to determine the powering on and powering off
points of the OUTPUT LED and fix the sensor in the middle of these two points.
•
Press the SET button until the READY LED turns off. The sensor acquires the reflector.
Alternatively, use the IO-Link Standard command “SP1 Single Value Teach”. If the READY
LED turns permanently ON the acquisition was successful. If the READY LED blinks
quickly the acquisition failed due to insufficient contrast. Press the SET button and the
sensor returns to the previous setting. Repeat the procedure after checking the alignment
of the sensor with the reflector and the operating distance.
Check:
•
Enter the detection area laterally with the object and check that the OUTPUT LED turns
on (in Dark mode).
•
Remove the object and check that the OUTPUT LED turns off immediately (in Dark mode).
MAX. SENSITIVITY SETTING
To set the maximum sensitivity, press the SET button until the READY LED turn on again (3
s) or use the IO-Link Standard command “Max. Sensitivity”.
PNP SETTING
Press the SET button for 10 s to reset Pin 4 in PNP mode. Use this feature if Pin 4 is set in
NPN mode and the sensor must be connected again to an IO-Link master.
SWITCHING THRESHOLD AUTOMATIC ADJUSTMENT (T53)
The sensor automatically adjusts the switching threshold. In case of dirty optics or reflector
the received signal decreases, after 1 minute of low signal the sensor automatically adjusts
the switching threshold to compensate for such variation avoiding a continuous cleaning of
the optics. If the received signal is too low to be adjusted by the sensor, the output remains
swtiched on and the optical parts must be cleaned.
LIGHT/DARK MODE SETTING (B53, T53, U03)
Light mode setting
Rotate the trimmer counterclockwise
to set the Light mode (sensor ON
with the reflector).
Dark mode setting
Rotate the trimmer clockwise to
set the Dark mode (sensor ON in
presence of an object).
Alternatively, the IO-Link Standard commands “SSC1/SSC2 Config” can be used.
REMOTE input
The REMOTE signal carries out acquisition functions without using the SET push-button. The
REMOTE wire connected to +Vdc is equal to pressing the SET push-button, connected to
GND or not connected is equal to not pressing the SET push-button.
DO Pin (Pin 2) can be configured as REMOTE input using Output Type IO-Link parameter.
When the trimmer is enabled, the IO-Link Standard parameter “Delay Settings” can be used
for delay configuration.
