Malfunctions in Reading mode: oscillating mirror errors
¾
Check whether the "Device Ready" LED lights up.
If the LED does not light, see
.
Malfunction
Possible cause
Remedy
1. The oscillating mirror does not move.
Incorrect operating mode set in the
CLV490.
In the "CLV-Setup" program:
choose the O
SCILLATING
M
IRROR
tab, O
SCILLA
-
TING
M
IRROR
section.
Is O
SCILLATING
WITH
F
IX
A
MPLITUDE
or O
SCILLA
-
TING
WITH
V
ARIABLE
A
MPLITUDE
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.
•
O
SCILLATING
WITH
F
IX
A
MPLITUDE
set in the
CLV490 by mistake.
•
The oscillating amplitude is paramterized
in the wrong distance configuration
(here: no. 2).
•
The distance configuration (focus
position) was not changed.
•
From the O
SCILLATING
M
IRROR
tab, choose
O
SCILLATING
WITH

•
In the "CLV-Setup" program: choose the
R
EADING
C
ONFIGURATION
tab, click the
D
ISTANCE
C
ONFIGURATION
button. Is the
amplitude value set in the correct di-
stance configuration (here: no. 1)?
•
In the "CLV-Setup" program: choose the
D
EVICE
C
ONFIGURATION
tab. Assignment of
Inputs for "IN 3" and "IN 4": is focus
control selected?
Connect 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
•
"IN 3" or "IN 4" switching input has not
been assigned this function.
•
In the "CLV-Setup" program:
choose the O
SCILLATING
M
IRROR
tab. Is
"one-shot" selected?
•
Choose D
