Green
•
Lights up after power-up if the self-test was successful
Subsequent behavior depends on selected start option:
Start option: S

ARAMETERS
(default):
•
Blinks for approx. 10 s before lighting up constantly
(CLX 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.
(CLX has loaded the parameter set from the external parameter memory with
tolerated errors
1)
and starts reading mode straight away)
•
Lights up constantly
(CLX could not find an external parameter memory and loads the internal para-
meter set instead)
•
Blinks constantly together with the "Read Result" LED
2)
(The external parameter memory contains the parameter set for another CLX type,
or is corrupt.)
CLX has loaded the internal parameter set. It starts Reading mode but does not
output data over the host interface)

CLX has loaded the internal parameter set.
•
Blinks constantly together with the "Read Result" LED
2)
(The external parameter memory is either not connected or corrupt, or the
parameter set is too large to be copied).
CLX has loaded the internal parameter set.

Reading mode
Device Ready
Green
•
Lights up constantly
•
Extinguishes with new operating mode/function
Sensor
Green
•
Lights up if reading diode active.
(The laser diode is activated/deactivated by the reading pulse)
•
Lights up constantly in Free-running mode, since the laser diode is constantly
active
Read Result
Green
LED is linked to the "Result 2" 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 output is selected for the
"Result 2" output
1) We recommend that you check the parameter set manually, e. g. by printing out the entire configuration. For troubleshooting, see also

for the external parameter memory, Page 8-3
2) Stops blinking when you switch from Reading mode to Parameterization mode
