2.
Connect the PC to the terminal interface of the CLV. To do so connect the RS-232 data
connection cable to the 9-pin "Service" connector of the module (refer to
Connecting the CAN interface, Page 5-6
).
3.
Start Windows and the "CLV-Setup" software on the PC (refer to

6.
Carry out the download to the CLV. To do so, click on

The CLV operates with the standard decoder.
Activating the percentage evaluation:

in the menu bar.
The dialog box for prompting the distance configuration is opened.
9.
Click on the distance configuration which corresponds to the reading distance of the
object. (Default setting: No. 1, focal position F = 900 mm for CLV 450).
10. Confirm the dialog box with "OK".
The terminal emulator is opened and displays the reading result continuously (refer to
Chapter 6.5.2 Percentage evaluation, Page 6-21
During all the further steps observe the behavior of the
reading quality
(as a %)!
Line scanner with oscillating mirror:
In the percentage 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 (corresponding 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.
Carrying out fine adjustment:
11. Align the CLV so that the angle between the scan line and the bar code bars amounts
to approximately 90
°
.
12. In order to avoid disturbing reflections, turn the CLV out of the perpendicular so that the
emitted light impacts on the bar code at an angle of approx. 105
°
(line scanner)
(
).
13. If necessary, position the center of the scan line exactly on the bar code (
Auxiliary functions for adjusting, Page 4-10
).
14. Manually guide objects with bar codes successively under realistic conditions into the
reading area of the CLV and check the read result. If the objects move loosely, check
several different positions (angles) of the bar code and ensure that the limits of the
permitted reading angle is not exceeded.
15. Adjust the CLV so the "Good Read" rate lies between
70 ... 100 %
.
In case of different object sizes per defined reading range (distance configuration)
check the selected focal position and if necessary correct the parameterization (refer
