INSTRUCTION MANUAL
CONTROLS
OUT LED (yellow)
The yellow LED indicates the output status.
READY LED (green)
During functioning, the green LED permanently ON
indicates a normal operating condition and blinking
indicates an output overload condition.
DELAY LED (orange)
The orange DELAY LED ON indicates the timing
function activation on the digital output.
KEYLOCK LED (orange)
The orange KEYLOCK LED ON indicates the active keyboard status.
BARGRAPH
The reading sensitivity level is signalled on the bargraph.
PUSH-BUTTON (white)
The pressing of the
push-button unlocks the keyboard, memorises the
sensitivity and activates the digital output timing.
(red) and
(green) push-buttons
The sensitivity adjustment procedure is activated by pressing the
and
push-buttons.
See the “SETTING” paragraph for setup procedure indications.
INSTALLATION
The sensor can be positioned by means the two
Ø
3.5mm housing’s holes
using or threaded M5 holes with 6 mm 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.
Operating distance is rated starting from the lens front face.

SETTING
KEYLOCK function (patent-covered)
The KEYLOCK function deactivates the keyboard thus avoiding accidental
changes in the sensor setting.
At sensor powering the keyboard is blocked (KEYLOCK LED OFF). To
activate it, press
for 5 seconds until the KEYLOCK LED (orange) turns
ON.
The keyboard is automatically blocked if not used for 2 minutes.
Unblock the keyboard to proceed with sensor adjustment.
NORMAL FUNCTIONING
During normal functioning a LED on the bargraph
visualises the sensitivity level.
SENSITIVITY ADJUSTMENT
This mode regulates the sensor reading sensitivity, i.e.
the capability of detecting objects with different
luminescence degrees.
The sensitivity is increased or decreased by pressing
the
or
push-buttons.
The adjustment speed is increased by keeping the
or
push-buttons pressed.
The sensitivity level which is being set blinks on the bargraph during this
phase.

Press
to memorise the new threshold value or wait 30sec for automatic
save.
DELAY SETTING
The DELAY extends the minimum active output status duration to 20ms,
allowing even slower interface systems to detect shorter pulses.
The delay is signalled by the corresponding orange LED ON.
Delay activation
-
Press
for 2 sec until DELAY LED turns ON.
Delay deactivation
-
Press
for 2 sec until DELAY LED turns
OFF.
OUTPUT OVERLOAD
The digital output overload is signalled by the rapid blinking of the READY
LED.
ANALOGUE OUTPUT
The analogue output supplies a voltage proportional to the signal received by
the sensor. The voltage supplied is 0.75 ÷ 5.5V.
