Installation
Once the CLV has started, it outputs a tone to indicate that the self-test was
successfully completed. Shortly afterwards, it outputs two tones consecutively to
indicate that it has assumed Reading mode. The "Device Ready" LED lights up.
2. Align the CLV optimally with the bar code on the object ( see Chapter 4.3.2 Adjusting the
CLV, Page 4-7 ).
3. Choose a suitable polling reflector for the device type, as shown in Table 4-2,
Page 4-11 . Other ranges available on request.
4. Secure the polling reflector directly opposite the CLV on a suitable base (movable
bracket, wall) temporarily so that the CLV has an unobstructed view of the reflector in
the gaps between the objects and can scan them reliably. The reflector must be in the
center of the scan line, see Fig. 4-11 .
Activating “Percentage Evaluation“ mode
5. From the V
IEW
menu, choose P
ERCENTAGE EVALUATION
.
The dialog window for choosing the
DISTANCE CONFIGURATION
is then displayed.
6. Confirm the dialog window with "OK".
The Terminal Emulator is launched and displays the reading result continuously ( see
Chapter 6.5.2 Percentage evaluation, Page 6-17 ).
Fine-adjusting and securing the polling reflector
7. Align the reflector with the CLV (not vice versa!) until a good read rate of 95 to 100 %
is reached. In doing so, prevent any surface reflection ( see Chapter 4.2.7 Distance
between the CLV and the bar code, Page 4-4 ).
The CLV outputs the data content of the unconcealed polling reflector with the identifier
"REPO".
8. Once the device is in the final attachment position, remove the protective film from the
rear of the reflector and stick it to the base.
