CONTROLS
OUT LED (yellow)
The yellow LED indicates the output status.
DISPLAY (green 4-digit display)
In MARK mode the display indicates a value relative to
the light quantity diffused by the target, in color mode on
the display ‘Colr’ text is written.
READY LED (RDY)
The green READY LED ON indicates a normal operating
condition where the received signal has a safety margin
respect to the output switching value: stability condition.
DELAY LED
The green DELAY LED ON indicates the timing activation on the digital
output.
KEYLOCK LED
The green KEYLOCK LED ON
isn’t active.

PUSH-BUTTONS
See the “SETTING” paragraph for the correct adjustment phase indications.
INSTALLATION
The sensor can be positioned by means of the two
Ø3.5
mm
housing’s holes
or using threaded M5 holes with 6mm max. depth.
Warning:
the use of excessively long screws can damage the product.
The connector can be oriented at five different positions by rotating the block.
The position chosen is guaranteed by a mechanical blocking system.
The rotation can be carried out even after sensor installation as the connector
block is completely self-contained inside the housing.
The operating distance is measured starting from
the lens front face.
The reading direction can be changed inverting
the cap and lens.
Mark detection on a reflective surface is
improved adjusting the beam direction to 5° …
20° from surface axis.
CONNECTIONS
SETTING IN MARK MODE
DETECTION (MARK-BACKGROUND)
-
Position mark in front of the sensor light spot and press the
push-button until the
‘SEt1’ text appears.
The sensor detects the mark alternating the red, green and blue emissions.
Avoid mark movements until the ‘SEt2’ text appears
and the OUT LED blinking.
- Position the background in front of the sensor light
spot and press the
push-button again. The
sensor detects the background and automatically
selects the best emission to detect the contrast.
Avoid background movements during this phase.
The DARK/LIGHT operating mode is automatically
selected by the sensor.
Dark mark - light background
dark mode; light
mark - dark background
light mode.
If the detection has been successful, the sensor
returns to normal functioning. If it fails due to
insuffi
cient contrast, the ‘FAIL’ test blinks on the
display. Press the
push-button and the sensor
returns to the previous setting.
Repeat the procedure from the beginning.
DYNAMIC SETTING
Use the dynamic setting to detect moving target. The sensor sets automatically the
threshold value during target movement. The DARK/LIGHT mode must be set first. To
select the light mode connect the DARK/LIGHT signal (white wire) to 0V or leave
unconnected. To select the dark mode connect the DARK/LIGHT signal to the power
supply.
-
Position the sensor spot in front of the
target to detect. Press
until the
‘dYn’
text blinks (4sec) and keep it pressed. The
sensor detects the mark and automatically
selects the best emission to detect the
contrast.
-
To end the dynamic detection procedure
release the
push-button.
If the detection has been successful, the
sensor returns to normal functioning. If it fails
due to insufficient contrast, the ‘Lo’ text
blinks on the display.
Press the
push-button to repeat procedure until rele
asing the button (the ‘dYn’ text
blinks on the display). The sensor returns to the previous setting by pressing
or
.
SWITCHING THRESHOLD SETTING
The sensor switching threshold can be adjusted as follows.
The ‘AdJ’ text appears pressing
on the display. Releasing the push-button, the
threshold value blinks.
The switching threshold is increased or reduced by pressing
or
.
Press
to save the new threshold value.
SETTING IN COLOR MODE
COLOR DETECTION
Position the color in front of the sensor light spot and press the
push-button until the
‘SEtc’ text appears.
The sensor detects the color.
Avoid color movements until the ‘SEtc’ text disappears.
If the detection has been successful, the sensor returns to normal functioning. If it fails
due to insufficient intensity
, the ‘FAIL’ test blinks on the display. Press the
push-
button and the sensor returns to the previous setting.
Repeat the procedure from the beginning.
SWITCHING TOLERANCE SETTING
The sensor tolerance can be adjusted as follows.
The ‘Tolx’ text appears pressing
on the display. Releasing the push-button.
The tolerance level increases from “toL0” to “toL9”. To detect small chromatic
differences, select lower tolerance levels.
The Tolerance value is increased or reduced by pressing
or
.
Press
to save the new Tolerance value.
SETTING IN ALL MODES
HYSTERESIS SETTING
The sensor hysteresis level is adjusted.
The ‘HYSt’ text appears pressing green
on the display.
When the push-button is released, the previously set value blinks.
HIGH HYSTERESIS
NORMAL HYSTERESIS
LOW HYSTERESIS
The level switches by pressing
or
.
Press
to save the new hysteresis value.
OUTPUT OVERLOAD
The overload of the digital output is signalled by the ‘_SC_’ text on the display. The
sensor returns to normal operation when the overload condition disappears.
PARAMETER SETTING
Some parameters can be changed entering the menu: MARK/COLOR mode,
NORMALLY OPEN/CLOSE, DELAY ON, DELAY OFF, display orientation and powering
on/off, RESET and save setting.
Press
and
together
until the ‘Menu’ text appears.
Releasing the push-button, the first Mark/Colr parameter appears.
The parameter list is shown by pressing
and
:
MARK/COLOR setting
The sensor can be configured in MARK or COLOR mode.
Select ‘Mark’ or ‘Colr’ in the parameter menu to switch the mode.
The previously set mode switches by pressing
.
NORMALLY OPEN/CLOSE setting (only in COLOR mode)
The output in color mode can be configured as normally open or normally
close.
Select ‘OPEn’ or ‘ClOS’ in the parameter menu to switch the output.
The previously set output switches by pressing
.
