Luminescence sensor

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
sensitivity and activates the digital output timing.

(red) and (green) push-buttons

The sensitivity adjustment procedure is activated by pressing the
push-buttons.

See the “SETTING” paragraph for setup procedure indications.

The sensor can be positioned by means the two Ø3.5mm 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
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

push-buttons pressed.

or
The sensitivity level which is being set blinks on the bargraph during this

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.

OUTPUT OVERLOAD

The digital output overload is signalled by the rapid blinking of the READY
LED.

ANALOGUE OUT PUT

The analogue output supplies a voltage proportional to the signal received by
the sensor. The voltage supplied is 0.75 ÷ 5.5V.
