Troubleshooting
Additional for CLV integrated in OTS 400 Omni Portal System
3. The data content of the bar code output
by the CLV is incorrect or incomplete
• The data format on the host interface is
parameterized incorrectly in the CLV
• The CLV suppresses the last character in
the bar code
• In the "CLV-Setup" program: choose the
HOST INTERFACE tab, DATA FORMAT section.
Are the values correct?
• In the "CLV-Setup" program: choose the
CODE CONFIGURATION tab. For the corre-
sponding code click the EDIT button.
Is the TRANSMIT CHECK DIGIT checkbox ac-
tivated? Change if necessary. Download
to CLV!
4. The CLV transfers the status ST=3 to the
host in the reading result (outputting of
ST disabled by default)
The CLV has diagnosed a device error in the
self-test
Switch the CLV off and on again. Does the
"Device Ready" LED light up? If not, contact
the SICK Service department.
Malfunction Possible cause Remedy
Table 8-8: Troubleshooting: result output errors in Reading mode (CLV in stand-alone configuration) (contd.)
Malfunction Possible cause Remedy
1. OTS-trigger
Start/stop mode (no tracking)
in master/slave arrangement with
OTC 400
– the "Read Result" LED on CLV
(default setting: Good Read) does not
light up at the end of reading interval
• Incorrect focus position:
CLV is not receiving any distance
information from OTC 400 or
• Incorrect focus position:
Distance configuration for fixed focus in-
correctly parameterized
• In the "CLV-Setup" program:
Select READING CONFIGURATION tab,
FOCUS CONTROL section: is OTS height in-
formation selected?
• Check: FOCUS CONTROL section: STATIC/NO
TRIGGER selected?
Click DISTANCE CONFIGURATION button.
Focus position correctly selected?
2. OTS-trigger
Tracking mode
in master/slave arrangement with
OTC 400
– the "Read Result" LED on CLV
(default setting: Good Read) does not
light up during reading process
• Incorrect focus position: see above
• CLV is not receiving any increment
information from OTC 400
• Enable points incorrectly parameterized
in the CLV
• Remedy: see 1. Remedy
• Check connection and parametrization of
incremental encoder, see OTS 400
Operating Instructions (no. 8 008 869,
English edition)
• Check in the "CLV-Setup" program:
Select DEVICE CONFIGURATION tab, TRACK-
ING PARAMETERS button: values correctly
selected? Is the object enable point of
CLV within the limits of the object enable
point of OTC 400?
3. OTS-trigger
Tracking mode
in master/slave arrangement with
OTC 400
– OTC 400 not sending reading result to
the host
• If an incremental encoder is connected:
the sensor is transferring an incorrect
conveyor speed to the arrangement. As
a result, the OTC 400 cannot correctly
assign the bar codes to the objetcs
• If an internal increment pulse is used in
the arrangement:
the pulse does not match the actual con-
veyor speed
• Check contact between the incremental
encoder and conveyor belt
• If objects are read on a section between
belts, checks whether the conveyor
speed of the two belts is different
• Adapt the internal increment pulse to the
actual conveyor speed or connect an ex
-
ternal incremental encoder to the
OTC 400 if the conveyor speed is not
constant (parameterize switching input
accordingly)
