Operating mode LED Display Function
Start Device Ready Green • Lights up after power-up if the self-test was successful
Subsequent behavior depends on selected start option:
Start option: START WITH EXTERNAL PARAMETERS (DEFAULT)
• Lights up constantly (CLV has loaded internal parameter set)
Start option: START WITH INTERNAL PARAMETERS
• Lights up constantly (CLV has loaded internal parameter set)
Start option: START WITH COPY INTERN -> EXTERN
• Blinks constantly together with the "Read Result" LED
1)
(CLV has loaded internal parameter set)
Read Result Green
Start option: START WITH COPY INTERN -> EXTERN
• Blinks constantly together with the "Device Ready" LED
1)
Reading mode Device Ready Green • Lights up constantly
• Extinguishes with new operating mode/function
Sensor Green • Lights up if reading diode is active
(The laser diode is activated/deactivated by reading pulse)
• Lights up constantly in Free-running mode, since laser diode is always active
Read Result Green LED is linked to the "Result 2" switching output and indicates the selected result
status for the defined pulse duration of the output.
• Lights up after a successful read (default: Good Read)
• Lights up if the match code comparison is active, the bar code read matches the
specified match code(s) and the corresponding result status output is selected
for the "Result 2" output
Data Yellow • Flickers when the CLV transfers data to the host on the host interface
Percentage Sensor Green • Lights up constantly, as Free-running mode is active
evaluation Read Result Green Behavior depends on the reading quality:
• Extinguishes if reading rate < 30 %
• Blinks twice a second if reading rate 30 % to 70 %
• Blinks five times a second if reading rate 70 % to 90 %
• Lights up constantly if reading rate > 90 %
Adjusting mode Sensor Green • Lights up constantly, as Free-running mode is active
Show CP-limits Sensor Green • Blinks bright/dark alternately, in the frequency with which the scan line is (partially)
masked out
1) Set the start option to START WITH THE INTERNAL PARAMETERS on the DEVICE CONFIGURATION tab in the "CLV-Setup" program. Download to CLV!
