ERROR MESSAGES IN READING MODE
4. Reading Mode:
(Dev.
Rdy LED lit)
CLV does not transfer
reading result to host.
- The Data LED does not
flicker at the end of reading
pulse.
5. Reading Mode:
(Dev. Rdy LED lit)
CLV outputs ST=3 in
Reading Mode (If ST is
enabled for the separa-
tor)
6. Reading Mode:
(Dev. Rdy LED lit)
Output of bar code con-
tent incorrect or incom-
plete.
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
-The CLV has diagnosed a
device malfunction
1. 2/5 Interleaved: CLV sup-
presses the first character of
the code in the data output
string.
2. CLV suppresses the last
character of the code in the
data output string.
3. CLV outputs non-definable
characters.
1. Is the Dev. Rdy LED lit?
2. Is the Laser On LED lit at the corre-
sponding clock pulse?
3. Check wiring.
4. Values OK?
5a. Check data format, protocol, start and
stop characters and output format.
5b. With output sorting according to code
length list: check specified lengths (at
lease one

0)
Switch device off and on again, Does
LED light up after approx. 10 s?
-Switch device off and on again.
Does LED light up after approx. 10 s?
1. Does the CLV suppress the leading
zero?
2. Output of the last character is disabled
for this code type.
3. Data format set incorrectly.

Possible Cause
Check
Remedy
1. If not, switch device off and on
again.
If so, user interface: choose
Reading Mode.
2. See malfunction 2a, 2b or 2c.
3. Check pin assignment and con-
nection diagram.
4. Measure voltage values.
5a. User interface (after upload
from CLV): check settings on the
Host Interface and Data Strings
card and change if necessary.
Download to CLV.
5b. User interface (after upload
from CLV): check settings on the
Data Strings card and change
them if necessary. Download to
CLV.
If so, the device is OK. If not or if
the malfunction occurs again: con-
tact the SICK Service Department.
-If so, the device is O.K. If not or if
the malfunction occurs again: con-
tact the SICK Service department
