8.5.5 Malfunctions in Reading mode: oscillating mirror errors
¾
Check whether the "Device Ready" LED lights up.
If the LED does not light, see Table 8-5, Page 8-9 .
Malfunction Possible cause Remedy
The
– "Result 1"
(default setting: Device Ready)
– "Result 2"
(default setting: Good Read)
– "Result 3"
(default setting: No Read)
– "Result 4"
(default setting: Match 1)
switching outputs are not outputting any
pulses
•
The event associated with the assigned
function for outputting the result status of
the read does not occur in the reading
operation
•
Incorrect switching mode parameterized
in the CLV
•
Not applicable.

Malfunction Possible cause Remedy
1. The oscillating mirror does not move. Incorrect operating mode set on the CLV In the "CLV-Setup" program choose the
O

section.
Is O

selected?
2. The oscillating mirror oscillates with
maximum deflection (40 CW), even
though a variable amplitude, e. g. 10 CW,
is set in the distance configuration 1

•
The oscillating amplitude is paramterized
in the wrong distance configuration
(here: no. 2)
•
The distance configuration (focus
position) was not changed

sensors to the switching inputs. Check
sensor wiring (see

Measure output signal at sensor
3. One-Shot: The One-Shot function cannot
be triggered (sensor correctly connected
to the "IN 3" or "IN 4" switching input)

Trigger source incorrectly parameterized
•
