Malfunction
Possible cause
Remedy
1.
AutoSetup:
The CLV does not read the presented,
application-specific bar code (no
confirmation from beeper)
•
CLV not in "AutoSetup" mode
•
If AutoSetup is started with profile bar
code no. 10: wait time of 5 s after power-
up has been exceeded
•
Bar code presented at incorrect reading
distance
•
Bar code is in total reflection zone
•
Bar code quality not adequate
•
Check: Does the "Device Ready" LED
light up? If so, the CLV is in "reading"
mode again.
In CLV Setup program: Restart
A
UTO
S
ETUP
from the V
IEW
pull-down
menu.
•
Switch the CLV off and on again.
Present profile bar code no. 10 within
5 s.
Then present the application-specific bar
code.
•
Check: Is the reading distance of the bar
code within the specified reading area?
•
Optimize bar code alignment (scan line
should strike the bar code at an angle of
approx. 15
°
).
•
See
Malfunction 1
,
2.
Profile programming:
CLV does not read the presented
profile bar code (no confirmation from
beeper)
•
Wait time of 5 s after power-up has been
exceeded
•
Wait time of 10 s after the first profile bar
code was presented has been exceeded
•
In reading mode: CLV not pulsed
•
Switch the CLV off and on again.
Present profile bar code within 5 s.
•
Once the first profile bar code has been
read successfully, present the next bar
code within 10 s, etc.
•
Clock the CLV accordingly and present
the first profile bar code. Present the next
bar code within 10 s, etc.
