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.

(green) 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 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.

Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: [email protected]

- 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.

The

DARK/LIGHT

operating

mode

automatically selected by the sensor.

Dark mark - light background  dark mode;

light mark - dark background  light mode.

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

until

the 'dYn' text blinks (4sec) and keep

it pressed. The sensor detects the

mark and automatically selects the

best emission to detect the contrast.

- To end the dynamic detection

procedure release the

push-

button.

If the detection has been successful,

the

sensor

returns

normal

functioning. If it fails due to insufficient

contrast, the 'Lo' test blinks on the display. Press the

repeat procedure until releasing the button (the 'dYn' text blinks on the

display). The sensor returns to the previous setting by pressing

SWITCHING THRESHOLD SETTING

The sensor switching threshold can be adjusted in this manner.

The 'AdJ' text appears pressing

on the display. Releasing the push-

button, the threshold value blinks.

The switching threshold is increased or reduced by pressing

Press

to save the new threshold value.

HYSTERESIS SETTING

The sensor hysteresis level is adjusted.

The 'HYSt' text appears pressing green

on the display.

Releasing the push-button the previously set value blinks.

HIGH HYSTERESIS

NORMAL HYSTERESIS

LOW HYSTERESIS

The level switches by pressing

Press

to save the new hysteresis value.

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.

PARAMETER SETTING

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.

Press

and

contemporarily until the 'Menu' text appears.

Releasing the push-button, the first Delay ON parameter appears.

The parameter list is visualised by pressing

DELAY ON setting

The DELAY ON represents the output delay activation after the reference

mark has entered in the detection area. The delay avoids the detection of

events that occur rapidly. An example can be a mark with shaded colours

(light-dark-light) that can be detected twice.

push-button to

Select "dLOn" in the parameter menu to set the DELAY ON function.

The parameter programming is accessed by pressing

The previously set delay value appears on the display.

Pressing

the delay value is increased or decreased by one step of

1 ms until a maximum delay of 100ms. Keeping press

value is increased or decreased by incremental step. The setting of a delay

different from zero is signalled by the DELAY LED on. Press

the value and return to the parameter menu.

DELAY OFF setting

The DELAY OFF represents the output delay deactivation after the reference

target has left the detection area.

The delay extends the output activation allowing slower system interfacing

with sensors to detect shorter pulses.
