Troubleshooting
Additional for CLV integrated in OTS 400 Omni Tracking 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
H
OST
I
NTERFACE
tab, D
ATA
F
ORMAT
section.
Are the values correct?
•
In the "CLV-Setup" program: choose the
C

ONFIGURATION
tab, S
YMBOLOGIES
section. Click the E

button of the rele-
vant code.
Is the T

activated? Change if necessary.

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
1.
OTS
Reading mode: "Start/stop"
– The "Read Result" LED on CLV
(default setting: Good Read) does not
light up at the end of reading
interval
If the CLV uses distance information from
OTC 400 or other CLVs:
CLV is not receiving any distance informa-
tion.
In the "CLV-Setup" program: choose
R
EADING
C
ONFIGURATION
tab, F
OCUS
CONTROL
section: "OTS height information" selected?
2.
OTS
Reading mode: "Tracking"
– The "Read Result" LED on CLV
(default setting: Good Read) does not
light up during reading process
•
CLV is not receiving any increment
information from OTC 400.
•
Release points incorrectly parameterized
in the CLV.
•
Check connection and parameterization
of incremental encoder on the OTC 400,
see
OTS 400
Operating Instructions
(no.
8 008 869, English edition).
•
In the "CLV-Setup" program: choose the
D
EVICE
CONFIGURATION
tab, click the T
RACK
-
ING
P
ARAMETERS
button: are the values
correct? Is the object release point of
CLV within the limits of the object release
point of OTC 400?
3.
OTS
Reading mode: "Tracking "
– OTC 400 not sending any reading
results 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 bar codes to the objects.
•
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 OTC 400
if the conveyor speed is not constant
(parameterize switching input according-
ly)
