Troubleshooting

8.5.3 Malfunctions in Reading mode: result output errors

¾ Check whether the "Device Ready" LED lights up.

If the LED does not light, see Table 8-5, Page 8-9.

CLV490 in stand-alone configuration

Here: number of bar codes to be read = 1

Malfunction Possible cause Remedy

1. The "Read Result" LED (default setting:

Good Read) does not light up at the end

of the reading pulse.

– The "Result 2" switching output

(default setting: Good Read) is not

outputting a pulse

– The CLV490 outputs status ST=2 in

the reading result on the host inter-

face

(outputting of ST disabled by default)

– The CLV490 outputs the message

"no code" in the reading result of the

auxiliary interface

• Read not successful, since there was no

bar code in the reading field during the

reading pulse.

• Scan line positioned incorrectly.

• Bar code presented at incorrect reading

distance.

• The presented bar code’s module width

cannot be read by the CLV490 type be-

ing used.

Reading range (bar code evaluation range):

• Evaluation range of the scan line is

limited unfavourable (reading angle valu-

es).

– or –

• Parametrized rectangular reading area

does not match the conditions in situ.

• Position of the CLV490 referred to the

reading space not or incorrectly

parameterized.

Focus control:

• Focus control not activated.

• Synchronize read with presence of an

object in reading field. See Chapter 8.5.2

Malfunctions in Reading mode: reading

trigger errors, Page 8-10.

• Align CLV490. Is bar code at center of

scan line? Check the reading quality with

the "CLV-Setup" program: choose P

ER-

CEN-

TAGE EVALUATION. See Chapter 6.5.2 Per-

centage evaluation, Page 6-41.

• Check whether reading distance of bar

code is in the specified reading range?

• Present a bar code with an acceptable

module width. See Chapter 9 Technical

data, Page 9-1.

• In the "CLV-Setup" program: choose the

READING CONFIGURATION tab, click the AU-

TOFOCUS PARAMETERS respectively

DISTANCE CONFIGURATION button.

Are the min. and max. reading angle

values correct? Check with S

HOW RA-

LIMITS. See Chapter 6.5.5 Show RA-limits,

Page 6-46.

• In the "CLV-Setup" program: choose the

READING CONFIGURATION tab, READING AREA

section, READING AREA option, click the

EADING SPACE PARAMETERS button: are

the values for reading space correct?

• In the "CLV-Setup" program: choose the

EVICE CONFIGURATION tab, click the SCAN-

NER POSITION PARAMETERS button: are the

values correct?

• In the "CLV-Setup" program:

choose the READING CONFIGURATION tab,

OCUS CONTROL section: "Autofocus" or

"Inputs/serial" for event-controlled focus

position switchover selected? (for oscil-

lating mirror also "Oscillating Mirror Ex-

trema")
