INSTRUCTION MANUAL
CONTROLS
OUT LED (yellow)
The yellow LED indicates the output status.
DISPLAY (green 4-digit display)
During normal functioning, the display indicates a value
relative to the light quantity diffused by the target.
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 indicates the active keyboard status.

INSTALLATION
The sensor can be positioned by means the two Ø3.5mm housing's holes
using or 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.

SETTING
KEYLOCK FUNCTION (PATENT-COVERED)
The KEYLOCK function deactivates the keyboard avoiding any accidental
changes in sensor setting.
At sensor powering, the keyboard is blocked (KEYLOCK LED OFF).
The
push-button has to be pressed for 5 sec. until the KEYLOCK LED
turns ON. The keyboard is blocked automatically if not used for 2 minutes.
The keyboard has to be unlocked to proceed with sensor setting.
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.

If the detection has been successful, the sensor
returns to normal functioning. If it fails due to
insufficient 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 has to be previously set. 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
the 'dYn' text blinks (4sec) and keep

it pressed. The sensor detects the
16 μs
mark and automatically selects the
30 kHz
best emission to detect the contrast.
- To end the dynamic detection
procedure release the
button.
If the detection has been successful,
the
sensor
returns
to
functioning. If it fails due to insufficient
contrast, the 'Lo' test blinks on the
display. Press the
push-button to repeat procedure until releasing the
9 mm
button (the 'dYn' text blinks on the display). The sensor returns to the
± 3 mm

OUTPUT OVERLOAD
The overload of the digital output is signalled by the '_SC_' text on the
display. The sensor return to normal working when the overload condition
disappears.
Some parameters can be changed entering in the menu: DELAY ON, DELAY
OFF, PNP/NPN switching output, display orientation and powering on/off of
the display.
