2.
Present the first Profile bar code in the printed sequence (or the desired Profile bar code
from the card) within 5 seconds. Fold the printout/card in such a way that only one Pro-
file bar code is visible at any one time.
The CLV confirms that the bar code has been read successfully by outputting an acous-
tic signal via the beeper and waits
10 seconds
for the next Profile bar code.
It copies the new parameter value(s) to the current parameter record in the RAM.
3.
Present the next Profile bar code within 10 seconds.
The CLV confirms that the bar code has been read successfully as described in Step 2.
4.
Allow 10 seconds to pass after the last Profile bar code has been read.
The CLV exits the programming mode and saves the new parameter values permanent-
ly in the EEPROM. It also switches off the laser diode.
Following this, it returns to the Reading mode and confirms this by outputting two con-
secutive acoustic signals via the beeper. The "Device Ready" LED lights up.
The CLV then uses the new parameter values.
Performing Profile programming in the Reading mode
1.
Start the reading pulse: Block the light path of the photoelectric switch or close the
switch.
The "Laser On" LED lights up. The scan line then appears.
2.
Present the first Profile bar code in the printed sequence (or the desired Profile bar code
from the card).
Fold the printout/card in such a way that only one Profile bar code is visible at any one
time.
The CLV confirms the successful read by emitting an acoustic signal and waits
10 seconds
for the next Profile bar code.
It copies the new parameter value(s) to the current parameter record in the RAM.
Continue Profile programming as from Step 3 as described in Section
programming after switching on the supply voltage“

Note
When the Profile bar code is presented to the CLV, note that the changes caused by the
new parameter values in the RAM can have an immediate effect on the reading behavior of
the CLV. Under unfavorable conditions, the CLV will only be able to read Profile bar codes
with great difficulty or not at all.
Changes to the active evaluation range of the scan line (min./max. CP value), an increase in
the scanning frequency and changes to the focal position must, therefore, be presented with
care.
If the CLV is not able to read any further Profile bar codes, it must be corrected accordingly
in the tab cards by means of the CLV- Setup user interface. A PC must be connected to the
CLV for this purpose.
Cancelling Profile programming
¾
Switch off the supply voltage of the CLV within 10 seconds of presenting the last Profile
bar code.
The temporary changes to the current parameter record in the RAM are lost. After the
supply voltage has been switched on again, the CLV uses the values from the last pa-
rameter record that was stored permanently.
