When an error indication not listed above is displayed, contact your nearest
KEYENCE office.

RECEIVED LIGHT INTENSITY INDICATION

In the received light intensity indication, the number larger than 9 at the top
digit is substituted with an alphabet.
Maximum value displayed: P599 Actual value: 25599

■ Denotation of indication

Precaution on Using the CZ-H52

This sensor uses an ultraviolet LED as the light emitting source and a light
receptor element that has the enhanced sensitivity in the visible region. The
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

Class 1M LED

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.

SAFTY PRECAUTIONS

• Isolate the sensor cable from the power line or the high voltage line.

The use of these lines in the same pipe generates noise, which may cause
malfunction.

• When a number of colors enter into the beam spot, they are averaged

down in recognition, resulting in the output of the color that is different from
the preset color.

• To extend the amplifier cable, use the cable with the nominal cross-sec-

tional area no less than 0.3 mm

, 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 head
cable length, and different mounting conditions.

Countermeasures

nnnn

Received light intensity
is insufficient.

• 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.

vvvv

Received light intensity
is excessive.

Turn on the attenuation mode.
• Tilt the sensor head by approx. 10 to 15

degrees.

Erk

Sensor head is not
connected.
Head cable is broken.

• Check that the sensor head is

connected.

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

power again.

Er[

Overcurrent flows
through the output
wire.

• 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.
