8.5.4 Malfunctions in reading mode: errors when outputting the result status
Prerequisite The "Device Ready" LED lights up. If not, see Table 8-3, Page 8-5.
8.5.5 Malfunctions: configuration errors (parameterization)
Prerequisite The "Device Ready" LED lights up. If not, see Table 8-3, Page 8-5.
Malfunction Possible cause Remedy
1. The "Result 1" (default setting:
"Device Ready") and "Result 2"
(default setting: "Good read")
switching outputs are not outputting
any pulses.
• The event of the assigned function for
outputting the result status does not
occur during the reading process
• Incorrect switching mode parameterized
in CLV
• not applicable
• In the CLV Setup program: Check by
choosing the
DEVICE CONFIGURATION tab.
Click the
RESULT OUTPUT PARAMETERS
button. Are the outputs set to
"Invert
Output"
?
Change if necessary. Download to CLV!
2. The beeper is not confirming the
output of the reading result (default
setting: "Good read").
Beeper deactivated In the CLV Setup program: Check: Check by
choosing
DEVICE CONFIGURATION tab, group
BEEPER VOLUME: is "Low" or "High"
selected?
Table 8-6: Troubleshooting: errors in the result status output in reading mode
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
UTOSETUP from the VIEW 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, Table 8-5, Page 8-7
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.
