Operation
6.3 Quick start
A PC does not need to be connected when the CLV is operated with the factory default
settings (this is, however, not the case the first time the CLV with external parameter
memory is switched on, see Chapter 6.3.2 Switching the CLV with external parameter me-
mory connected on for the first time with the factory default settings, Page 6-4 ).
6.3.1 Switching the CLV on for the first time 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
switching inputs, Page 5-16 ).
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:
If an external parameter memory is connected to the CLV, the "Device Ready" LED
blinks for 10 s when the device starts up correctly and then lights up constantly. If the
"Device Ready" and "Read Result" LEDs both blink constantly, the memory is empty
and the CLV is not ready for operation.
In this case, proceed as described in Chapter 6.3.2 Switching the CLV with external pa-
rameter memory connected on for the first time with the factory default settings,
Page 6-4 .
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 scan
line appears.
5. Present the bar code pattern ( Fig. 6-1 ) to the CLV at the reading distance specified in
Table 6-3, Page 6-4 .
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 para-
meter set.
