6.3 Quick start
A PC need not be connected when the CLV is operated with the factory default settings.
Code 39, 2/5 Interleaved, and Code 128 are the default code types enabled (free code
lenght, 2/5 Interleaved: interval 4 to 50 characters).
6.3.1 Starting up the line/raster scanner with the factory default settings
1. Connect the CLV to the SICK CDB 420 or CDM 420 connection module.
2. Connect the reading pulse sensor (e.g. photoelectric switch, switch) to the "Sensor 1"
switching input of the CLV via the CDB 420 or CDM 420. See Chapter 5.5.7 Connecting
the "Sensor 1" switching input, Page 5-8 .
3. Switch on the power supply to the CDB 420 or CDM 420.
Once the CLV has started, it outputs a tone to indicate that the self-test was
successfully completed. Shortly afterwards, it outputs two tones to indicate that it has
assumed reading mode. The "Device Ready" LED lights up. The "Result 1" ("Device
Ready") output switches.
4. Start the reading pulse: block the light path of the photoelectric switch or close the
switch.
The "Laser On" LED lights up. The CLV switches the laser diode on and the red scan
line appears.
5. Present the bar code pattern from Fig. 6-1 to the CLV at the reading distance specified
in Table 6-2 .
6. Align the bar code in such a way that the red scan line is almost at a 90
°
angle to the
bars.
7. End the reading pulse: unblock the light path of the photoelectric switch or open the
switch.
The "Laser On" LED is extinguished. The CLV switches off the laser diode.
The CLV confirms that the bar code was read successfully by outputting a tone via the
beeper. The "Result" LED lights up for duration of 100 ms. The "Result 2" (Good read)
output switches for the duration of 100 ms.
The CLV can now be operated with the factory default settings.
The device can be switched off without the configuration data being lost as no changes have
been made to the parameter set.
