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

1. The oscillating mirror does not move. Incorrect operating mode set in the

CLV490.

In the "CLV-Setup" program:

choose the OSCILLATING MIRROR tab, OSCILLA-

TING MIRROR section.

Is OSCILLATING WITH FIX AMPLITUDE or OSCILLA-

TING WITH VARIABLE AMPLITUDE 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 FIX AMPLITUDE 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 OSCILLATING MIRROR tab, choose

OSCILLATING WITH VARIABLE AMPLITUDE.

• In the "CLV-Setup" program: choose the

READING CONFIGURATION tab, click the

DISTANCE CONFIGURATION button. Is the

amplitude value set in the correct di-

stance configuration (here: no. 1)?

• In the "CLV-Setup" program: choose the

DEVICE CONFIGURATION tab. Assignment of

Inputs for "IN 3" and "IN 4": is focus

control selected?

Connect sensors to the switching inputs.

Check sensor wiring (see Fig. 5-6,

Page 5-23).

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 MIRROR tab. Is

"one-shot" selected?

• Choose D

EVICE CONFIGURATION tab.

SSIGNMENT FOR INPUTS section: "IN 3" or

"IN 4": is trigger "One-Shot" selected?
