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
H
OST
I
NTERFACE
tab, D
ATA
F
ORMAT
section.
Are the values correct?
•
In the "CLV-Setup" program: choose the
C
ODE
C
ONFIGURATION
tab. For the corre-
sponding code click the E
DIT
button.
Is the T
RANSMIT
C
HECK
D
IGIT
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
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 R
EADING
C
ONFIGURATION
tab,
F
OCUS
C
ONTROL
section: is OTS height in-
formation selected?
•
Check: F
OCUS
C
ONTROL
section: S
TATIC
/N
O
T
RIGGER
selected?
Click D
ISTANCE
C
ONFIGURATION
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 D
EVICE
C
ONFIGURATION
tab, T
RACK
-
ING
P
ARAMETERS
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)
