CLV 41x Bar Code Scanner

12. 1 Self-monitoring function

The CLV is equipped with the following monitoring functions:

•

After it is switched on, the device always performs a self-test before it is initialized
in order to check the important hardware components.

•

During operation, the CLV constantly monitors the function of its laser diode and
the speed of its polygon mirror wheel. A watchdog circuit also responds to any
malfunctions in the device.

•

If the CLV detects a malfunction during the self-test or operation, it outputs the
error status ST=3 if this has been enabled for transfer to the host in the separator
of the output string (default setting: no).

12. 2 Error messages

The CLV does not output any error messages apart from the error status ST.

12. 3 Causes of error and troubleshooting

The following tools and resources are required to perform the troubleshooting
measures described in

Table 20

•

these Operating Instructions

•

set of tools

•

a measuring tape

•

a multimeter for measuring voltage and current values

•

a PC with the CLV Setup software

•

an RS 232 data connection cable, e.g. no. 2 020 319 from SICK

We recommend that you perform the troubleshooting measures in the following order.

12. Troubleshooting

Malfunction

The CLV is not

ready.

- The Dev. Rdy. LED

is not lit

- The Result 1 switching

output (default: Dev. Rdy)
is disabled

2a. Reading mode:

(Dev. Rdy. LED lit)

Pulse: reflector polling

The CLV cannot be
clocked.

- The Laser On LED flickers

but is not lit constantly.

- Red-light scanner: the

scan line is very faint

Possible cause

1. The operating voltage (4.5 ...30V

DC) is not connected

2. The CLV is not in Reading mode

3. The CLV has detected a

malfunction during the self-test

1. Incorrect reading pulse source set

in parameters

2. Reading distance incorrect

3. Polling reflector incorrect

4. Incorrect pulse sequence

(reflector is not covered to
start the reading interval)

Check

1a.Check power supply.

1b.Mechanical noise?
2. Return to Reading mode

3a. Switch the device off and on

again. Does the LED now
light up after approx. 10 s?

3b. Has the CLV sent the status

ST=3 in the data output
string (prerequisite: ST is
enabled for output in the
separator)?

1. Are the device parameter

settings for the reading pulse
correct?

2. Is the reading distance within

the defined reading field?

3. Is the polling reflector suitable

for the reading distance?

4. Is the reflector polling

sequence correct? (read: 1.
cover reflector, 2. read bar
code, 3. uncover reflector)

Remedy

1a.Check the wiring!

(see

Section 8.1

)

Measure the voltage value

1b.Listen to the housing
2a.User interface: call R

EADING

ODE

2b.or switch the device off and

on again

3a.If so, the device is ok. If not,

contact the SICK Service
department

3b.If so, contact the SICK Service

department

1. User interface: choose

2. Change reading distance (see

3. Choose correct reflector

(see

Section 9.2

)

4. Adjust sequence, see also
