Quick start
A PC need not to 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 CLV with the factory default settings
1.
Connect the CLV to the AMV/S 60 Connection Module using the two cables no. 2 020 302.
2.
Connect the reading pulse sensor (e. g. photoelectric reflex switch) to the "Sensor"
switching input of the CLV via the AMV/S 60 (see
Chapter 5.5.7 Connecting the "Sen-
sor" switching input, Page 5-17
).
3.
Switch on the power supply of the AMV/S 60.
The CLV starts. The "Device Ready" LED lights up. The "Result 1" ("Device Ready")
output switches.
CLV with external parameter memory connected
(default setting: Start with external parameters
):
If an external parameter memory containing a corresponding parameter set is connect-
ed to the CLV, the "Device Ready" LED blinks for 10 s when the device starts up cor-
rectly and then lights up constantly. If the external parameter memory is empty, the CLV
immediately copies its parameter set to the external parameter memory. Then the "De-
vice Ready" LED lights up. The CLV is ready for operation.
Line scanner with oscillating mirror:
In the default setting, the CLV deflects the scan line around the position CW = 50 with
a frequency of 1 Hz and an oscillating amplitude of
±
20
°
(
±
40 CW). 50 CW correspond
to a deflection angle below 105
°
.
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 (
) to the CLV at the reading distance specified in
6.
Align the bar code in such a way that the red scan line is almost at a 90
°
angle to the
bars (line scanner) or that the red scan line sweeps the bars at a 90
°
angle when it is
deflected (oscillating mirror).
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 the laser diode off. The
CLV confirms that the bar code was read successfully (the "Read Result" LED lights up
for 100 ms). The "Result 2" ("Good Read") output is switched for a 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.
