Operating Instructions

CLV 41x Bar Code Scanner
Malfunction
3. Reading mode:
(Dev. Rdy LED lit)
The Result LED does not
light up at end of reading
pulse.
(contd)
4. Reading mode:
(Dev. Rdy LED lit)
CLV does not transfer
reading result to host.
The Data LED does not
flicker at end of reading
pulse.
5. Reading mode:
(Dev. Rdy LED lit)
CLV outputs status ST=3
in Reading mode.
(If ST is
enabled for the separtor)
Possible cause
8. Evaluation criteria for bar code
types set incorrectly (C
ODE
C
ONFIGURATION
)
9. Code position reading zone (CP
values) have been changed
(default: Min. CP=0, Max.
CP=100)
10. The defined min. number of bar
codes to be read is higher than
the actual number in the reading
pulse
11. Bar code quality not sufficient
1. The CLV is not in Reading mode
2. No reading pulse supplied
3. Data connection cable wired
incorrectly
4. Voltage level incorrect
5. Host interface parameters
incorrect

CLV has diagnosed a device
malfunction
Check
8a.Are code type and length
parametrized correctly?

,
present bar code, the code
type is displayed followed by
the read quality.
8b.Determine
Code length
to be
read: enable code type, set
code length to F

11b.Is print contrast sufficient?
11c.Print tolerances (acc. to
specification) exceeded?
1. Is the Dev. Rdy LED lit?
2. Is the Laser On LED lit at the
corresponding clock pulse?
3. Check wiring
4. Values ok?
5a.Check data format, protocol,
start and stop charactes and
output format
5b.With output sorting according
to code length list: check
specified lengths (at least

Switch device off and on
again. Does LED light up after
approx. 10 s ?
Remedy
8a. User interface: activate
detected code type under

card, disable
all other types, download to
CLV
8b. User interface: set the
code length for the
relevant code type in E

VALUATION
and test
readability of bar code at
the center of the scan line
10. Adjust value accordingly
(for one code: min/max. = 1),
download to CLV!
11a.Check read with fault-free
reference code.
Bar code: enlarge label,
reduce module width or
print ratio (min. 2:1)
11b.Submit device for test (e.g.
by SICK Service
department)
11c. As 11b

If not, switch device off and
on again.
If so, user interface:
