The CLV outputs the CP value and the CW value on the host interface for each bar code
in the reading result. The values are displayed as a 3-digit number in the associated
"Code-Info/Separator" block.

Mounting and adjusting the device
4.3.1
Mounting the CLV
1.
Prepare the base for mounting the bracket as described in
.
2.
Place the object containing the bar code within the reading field of the CLV (in the posi-
tion at which it is to be read) with the conveyor belt switched off.
3.
Align the CLV with the bar code (in accordance with the scanning method) in such a way
that
– with the line scanner the back of the device with the LEDs is almost parallel with the
bar code surface
– with the line scanner with oscillating mirror, the broad side wall (back of the oscillating
mirror) is almost parallel with the bar code surface
All of the possible reading angles must be taken into consideration (see
).
4.
If it is relevant for the evaluation, note the count direction of the code position and code
angle (see
).
5.
Mount the CLV bracket on the base.
Risk of damage to the device
The maximum depth of engagement of the two blind hole threads M6 is 7 mm (0.28 in).
Longer screws will damage the device.
¾
Use screws with the correct length.
6.
Screw the screws M6 through the bracket into the blind hole threads of the CLV.
7.
Tighten the screws slightly.
8.
Adjust the CLV as described below.
4.3.2
Adjusting the CLV
The CLV can be adjusted in Percentage Evaluation mode. In this mode, the CLV displays the
quality of the bar code reads that enter the CLV reading field statically (the object is not mo-
ved on the conveyor belt). The CLV performs 100 scans and evaluates the reading
quality statistically. It then outputs the reading results every 2 s on the terminal interface.
The behavior of the "Read Result" LED also indicates the reading quality:
–
The LED is extinguished if reading quality is < 30 %
–
The LED flashes twice per second if the reading quality is 30 % to 70 %
–
The LED flashes five times per second if the reading quality is 70 % to 90 %
–
The LED is lit continuously if the reading quality is > 90 %
The scanning frequency in the default setting is 800 Hz.
