CLV490 Bar Code Scanner

Product description

CLV490 with external parameter memory connected

a) External parameter memory in connector cover

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 RA-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 CLV490!

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: S

TART WITH EXTERNAL PARAMETERS (default)

• Blinks for approx. 10 s before lighting up constantly

(CLV490 has loaded the parameter set from the external parameter

memory and starts reading mode straight away)

• Blinks for approx. 10 s together with the "Read Result" LED, then lights up

constantly.

(CLV490 has loaded the parameter set from the external parameter memory with

tolerated errors

and starts reading mode straight away)

• Lights up constantly

(CLV490 could not find an external parameter memory and loads the internal

parameter set instead)

• Blinks constantly together with the "Read Result" LED

(The external parameter memory contains the parameter set for a different

CLV490 type or is corrupt.

CLV490 has loaded the internal parameter set. It starts Reading mode but does

not output data over the host interface.)

Start option: START WITH INTERNAL PARAMETERS

• Lights up constantly (CLV490 has loaded internal parameter set)

Start option: START WITH COPY INTERN -> EXTERN

• Blinks alternately with the "Read Result" LED for approx. 10 s before lighting

up constantly

(CLV490 has successfully copied the internal parameter set to the external mem-

ory and has reset the start option to START WITH EXTERNAL PARAMETERS).

CLV490 has loaded the internal parameter set.

• Blinks constantly together with the "Read Result" LED

(The external parameter memory is either not connected or corrupt, or the

parameter set is too large to be copied).

CLV490 has loaded the internal parameter set.

1) We recommend that you check the parameter set manually, e. g. by printing out the entire configuration. For troubleshooting, see also Chapter 8.3.2 LED error messages

for the external parameter memory (connector cover), Page 8-3

2) Stops blinking when you switch from Reading mode to Parameterization mode
