Installation
1.
Connect the CLV to the AMV/S 60 Connection Module and switch on the power supply
(see
Chapter 5.5.3 Connecting the supply voltage, Page 5-14
After it has started, the CLV confirms that the self-test was successfuly and switches to
reading mode ("Device Ready" LED lights up).
2.
Connect the PC to the terminal interface of CLV. To do so, connect a 3-core RS 232
data cable (null modem cable) to the internal 9-pin "Service" plug of the AMV/S 60 (see
Chapter 5.5.5 Connecting the CAN interface, Page 5-16
).
3.
Start Windows and the "CLV-Setup" program (see
Chapter 10.6.3 Starting CLV-Setup,
).
Choosing the standard decoder:

The dialog box for entering the distance configuration appears.
8.
Click the relevant distance configuration for the reading distance:
with event-controlled dynamic focus control the distance configuration that matches the
reading distance of the object (default: no. 1, focus position F = 1,200 mm
(47.3 in)).
9.
Confirm the dialog box with OK.
The Terminal Emulator is launched and displays the reading result continuously (see
Chapter 6.5.2 Percentage evaluation, Page 6-28
).

Line scanner with oscillating mirror:
In the "Percent Evaluation" mode, the CLV behaves in the following manner:
– in "Oscillating" mode (default setting: oscillating with a fixed amplitude), the CLV shuts
off oscillation and positions the scan line under the angle CW
= 50 (corresponds to
an angle of deflection of 105
°
). This position cannot be altered.
– in "One-Shot" mode, the CLV also positions the scan line under the angle CW = 50
– in "Set Position" mode, the scan line’s selected position remains unchanged.
Performing fine adjustment:
10. Align the CLV in such a way that the angle between the scan line and the bars on the
bar code CLV is almost 90
°
. The oscillating mirror must be aligned in such a way that
the scan line is located at the center of the bar code, perpendicular to the bar code li-
nes, when it is in the neutral position (CW = 50).
11. To avoid interfering reflections, tilt the line scanner away from the vertical axis so that
the light strikes the bar code at an angle of approx. 105
°
(see
).
12. If necessary, position the scan line exactly at the direct center of the bar code.

13. Move objects carrying bar codes into the CLV reading field manually under realistic
conditions and check the reading result. If the objects are aligned randomly, or if the bar
