Product description

3.3.2 Function of the LEDs

Four LEDs indicate the operating status, activity of the laser diode, reading result status, and

data transfer on the host interface. The LEDs are located on the rear of the device (Fig. 3-6).

If the optional external parameter memory is connected, the LEDs also indicate whether the

memory was successfully accessed.

The meaning of the LEDs in the various operating modes/functions is shown in Table 3-2

and Table 3-3, Page 3-12.

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 (CLV490 has loaded internal parameter set)

Start option: START WITH INTERNAL PARAMETERS

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

Start option: START WITH COPY INTERN -> EXTERN

• Blinks constantly together with the "Read Result" LED

(CLV490 has loaded internal parameter set)

Read Result Green

Start option: START WITH COPY INTERN -> EXTERN

• Blinks constantly together with the "Device Ready" LED

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 CLV490 transfers data to the host on the host interface

1) Set the start option to START WITH THE INTERNAL PARAMETERS on the DEVICE CONFIGURATION tab in the "CLV-Setup" program. Download to CLV490!
