Contrast sensor

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

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.
