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.

Fast 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 switching threshold level is signalled on the bargraph.

PUSH-BUTTON (bianco)

The detection procedure is activated by pressing the

push-button.

(red) and

(green) PUSH-BUTTONS

The threshold adjustment procedure is activated by pressing the

push-buttons.

See the "SETTING" paragraph for the correct adjustment phase

indications.

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, 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.

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 white

push-button has to be pressed for 5 sec. until the KEYLOCK

LED (orange) 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 white

push-button until the

READY LED (green) turns OFF.

The sensor detects the mark alternating the

red, green and blue emissions; avoid mark

movements during this phase.

- Position the background in front of the

sensor light spot and press white

button again. The sensor detects the mark

alternating

the

red,

green

emissions. Avoid background movements

during this phase.

Dark mark - light background = dark mode;

light mark - dark background = light mode.

25 μs

If the READY LED is permanently ON, the

detection is successful. If the LED blinks

slowly, the detection has failed due to

insufficient contrast. The sensor returns to the

previous setting by pressing white

Repeat the procedure from the beginning.

SWITCHING THRESHOLD SETTING

The sensor switching threshold is adjusted by pressing the

buttons (respectively increasing or decreasing the value).

At the first pressure of the

bargraph turn ON.

Increasing or decreasing the threshold, the right or left LEDs blink with a

frequency proportional to the difference from the initial threshold value.

DELAY SETTING

The DELAY extends to 20ms the minimum duration of the active output

allowing the slower interfacing systems to detect shorter pulses.

The active delay is signalled by the corresponding orange LED ON.

PNP/NPN OUTPUT SETTING

The digital output can be PNP or NPN

configured.

- To change output press red

contemporaneously for 10 sec.

- The setting is signalled by the status change of the DELAY LED.

If the delay is active after pressing the push-buttons for 2 seconds, the

DELAY LED turns OFF, release the push-buttons only after LED re-

powering (10 sec.).

If the delay is deactivated after pressing the push-buttons for 2 seconds, the

DELAY LED turns ON, release the push-buttons only after LED turning off

(10sec.).

- The output setting is signalled by the KEYLOCK LED. Releasing the push-

buttons, the KEYLOCK LED blinks once if the PNP output is set, blinks

twice if the NPN output is set.

OUTPUT OVERLOAD

mode

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

LED.

REMOTE INPUT

The REMOTE signals carries-out the acquisition functions without using the

white

push-button.

The REMOTE wire connected to +Vdc is equal to pressing the white

push-button. Whereas, if the REMOTE wire is connected to GND or not

connected it is equal to not pressing the white

ANALOGUE OUTPUT

The analogue output supplies a voltage proportional to the signal received by

the sensor. The voltage supplied is 1 ÷ 5.5V. The maximum voltage is

obtained with reflective objects; on 90% white the voltage is equal to 3V.
