Matching rate

Displays the degree of correspondence between the target color calipated as a reference and the target color currently being detected.Setting range: 0 to 999 (larger value for higher matching rate)

Setting value

Displays the threshold value that judges how much correspondence between the color of the current target and the color of the target calipated as a refer-ence is considered as an identical color.Received light intensity

•The set value appears in green.

■2-point calipation (for discriminating two colors)

Place a target of which color is to be used as a reference onto the focus

position of the beam spot emitted from the sensor. Then press the SET button once.

"SET" appears in green on the setting value monitor.

button once.

•The set value appears in green.

■Pinpoint calipation (1-point calipation with a stricter criterion)

•The setting value becomes larger than that of 1-point calipation even if thesame target is used for calipation.

E CZ-V21(P)/V22(P)-IM

smaller the setting value, the rougher the detection becomes.

To change the setting value (displayed in green digits), press the UP or DOWN button.

■ Fine-adjusting by using a target

Fine-adjust the setting value by performing an adding or eleminating calipa-tion.

Adding calipation (setting-value decreasing calipation)

Set the target to be judged as an identical color. While holding down the SET button, press the DOWN button.

Eliminating calipation (setting-value increasing calipation)

Set the target not to be judged as an identical color. While holding down the SET button, press the UP button.

Permitting uneven color

At a 1-point calipation or a pinpoint calipation, the sensor continues sam-pling while the SET button is held down.

•The sampled colors are set to be judged as an identical color.

Setting value

At the sensitivity setting, the sensor automatically determines the setting value. The setting value can also be preset to a fixed value manually. In that case, perform the following operation.

Press the UP and DOWN buttons at the same time for three seconds or more.•"F" appears in green on the left-hand side of the setting value monitor.

The cancellation method is the same as the method of fixing the setting value.

With the “F” being on display, the setting value does not change from the fixed value even if the sensitivity setting is performed.

Place a target on the desired position. Then press the SET button for three seconds or more.

Check that "SET" flashes, and release the SET button.

Setting a sensitivity

■1

2-point calipation (basic)

Place a target onto the focus position of the beam spot emitted from the sensor. Then press the SET button once.

•"SET" appears in green on the setting value monitor.

2

Press the SET button once without the target.•The set value appears in green.

■Setting the maximum sensitivity (when maximizing the sen-1

sitivity)

Press the SET button and hold it for three seconds or more without the tar-get.

2Check that "SET" flashes, and release the SET button.

■Full auto calipation (when a target is moving)

1

While holding down the SET button, pass the target through the optical

axis.

2

Check that "SET" flashes, and release the SET button.

Fine-adjusting a sensitivity

■Fine-adjusting a sensitivity by changing the setting value

To change the setting value (displayed in green digits), press the UP or DOWN button.

Shift function

Forcibly synchronizes the received light intensity with the preset value.

•Regular shift inputs from a PLC or other device stabilizes the detection ofthe target that has a little light intensity difference. (For external inputs froma PLC or other devices, refer to page 6.)

•The shift function can be used when the shift function selection is set to ON(refer to page 5).■Manually selecting the light source

To select the light source manually, perform the following operations.

1

At the display of the received light intensity/light source selection, press the UP and DOWN button at the same time for three seconds or more. "F" appears on the left-hand side of the setting value monitor.2

Select a light source by pressing the UP or DOWN button.

•Once the light source is selected manually, the light source remainsfixed even if the sensitivity value is changed.To return to the automatic light source selection, press the UP and DOWN button at the same time for three seconds or more.

* The CZ-H52 does not have the light source selection function.

To exit the menu during setting, press the MODE button again for three sec-onds or more.

When using the CZ-H52, the function (detection) mode selecting screen and the cali-pation mode selecting screen do not appear because the detection mode of the CZ-H52 is fixed to the “Super I” mode.

If the Eco mode is turned on, three minutes’ absence of operation pings the sensor to the power saving state. (For switching to the Eco mode, refer to page 5.)

To return the display to the normal state, press any one of the operation buttons.

■Changing channels

The sensitivity can be set for each of the following number of channels depending on the detection mode.

•C/C+I mode: 8 channels (4 channels x 2 banks)•Super I mode: 4 channels (no bank selection)

* When using the CZ-H52, the 4 channels can be used.

To select the display channel, perform the following operation.

While holding down the MODE button, press the UP or DOWN button.

■Keylock

Disables the key operation to change settings.

While holding down the MODE button, press the UP button for three seconds or more.

The cancellation method is the same as that of locking.

■Interference protection function

The CZ-V20 series can prevent mutual interference by connecting several amplifier units.

Short-circuiting the pink wire as shown below for each model equals the operation of pressing the SET button.

The minimum input time is 20 ms.

The external calipation to the connected sub-units (CZ-V22(P), FS-T2(P), or PS-T2(P)) can be performed together with the main unit.

Lock only the sensor for which to perform external calipation. The setting content is the same as that of the main unit.

•Install the sensor within the specified detecting distance.

•Check whether the fiber cable is inserted into the sensor to its deepest end. (approx. 20 mm)

•Delay the response time.

Turn on the attenuation mode.

•Tilt the sensor head by approx. 10 to 15 degrees.

•Check that the sensor head is connected.

•Check that the head cable is not poken.•After checking these points, turn on the power again.

•Check the load and reduce the current to be within the rated range.

•Check that the output wire does not touch another wire or a frame.

malfunction.

•When a number of colors enter into the beam spot, they are averageddown in recognition, resulting in the output of the color that is different fromthe preset color.

•To extend the amplifier cable, use the cable with the nominal cross-sec-tional area no less than 0.3 mm2, and with the length no more than 100 m.•When using the commercially available switching regulator,

be sure to earth the frame ground terminal and the ground terminal.•Do not use the sensor outdoors.

•Even in the detection of the same color, the displayed value may vary due

to the reason such as amplifier’s individual characteristics, sensor headcable length, and different mounting conditions.

■Denotation of indication

sensor is designed to reliably and easily detect fluorescent marks (such as hidden marks painted with fluorescent paint, or fluorescent marks painted with fluorescent paint).

■Caution

The LED emits powerful ultraviolet light while turned on, which can be very dangerous to the unprotected human eye. Do not view directly with optical instruments (such as a microscope or a telescope or a magnifiers).Doing so may result in eye injury.

If there is a risk of reflected ultraviolet light entering the eye, wear protective goggles and avoid all risks of direct exposure to the eye.

■Precaution on Detection

Some fluorescent objects cannot be detected by this sensor even though they may be visible to the human eye. Check the types of fluorescence before use.

For your information, fluorescent materials include those which emit fluores-cent light, phosphorescent light, and light accumulated from light-accumula-tive materials.
