Note Profile bar codes read by the CLV during the percentage evaluation do not cause any
changes to be made to the parameter record and do not, therefore, affect the reading
process either.
The match codes cannot be programmed (teach-in) in the Percentage evaluation mode. The
codes are entered in the D
EVICE CONFIGURATION
tab card. Match code 1 can, however, also
be programmed using the teach-in method.
6.5.3 Adjusting mode
The "Adjusting mode" enables the center of the scan line to be optimally positioned on the
bar code. Chapter 4.3.3 Auxiliary functions for adjusting, Page 4-10 describes the procedu-
re after the adjusting mode has been called up. The CLV does not output a read result in
this mode.
The Adjusting mode can be called up under V
IEW
, under T
OOLS
as a device function (in the
dialog box) or via the terminal emulator.
Line scanner with oscillating mirror:
In the Adjusting mode the CLV behaves in the following manner:
– in “Oscillating“ mode (default setting: oscillating with a fixed amplitude), the CLV shuts
off oscillation and positions the scan line under the angle CW = 50 (corresponding to
an angle of deflection of 105
°
). This position cannot be altered.
– in “One-Shot“ mode, the CLV also positions the scan line under the angle CW = 50.
– in “Set Position“ mode, the scan line’s selected position remains unchanged.
1. Click on in the toolbar.
The terminal emulator window opens. The CLV is in the Reading mode.
2. Click on the A
DJUSTING MODE
radio button under D
EVICE MODE
.
The "Device Ready" LED is extinguished. The CLV aborts the Reading mode and blanks
the scan line as of position CP = 50 to position CP = 100.
3. Click on the R
EADING MODE
radio button in order to terminate the Adjusting mode.
The CLV then returns to the Reading mode and the "Device Ready" LED lights up.
6.5.4Show CP limits
In this mode, the CLV blanks certain parts of the scan line so that any limit values defined
for the active evaluation range of the scan line can be checked directly during parameteri-
zation. The restricted active evaluation range shortens the evaluation time for fast applica-
tions, for example, because the evaluation routine only has to take account of unblanked
parts of the scan line. The range is restricted by entering appropriate values for M
INIMUM
CODE POSITION
and M
AXIMUM CODE POSITION
in the E
DIT DISTANCE CONFIGURATIONS
dialog box in
the R
EADING CONFIGURATION
tab card.
"Show CP limits" is used to check whether the limit per activated distance configuration is
adapted distance-specifically for the selected setting at the focal position changeover
("Christmas tree effect"). The CLV does not output a read result.
"Show CP limits" can be called up under V
IEW
, under T
OOLS
as a device function (in the dialog
box) or via the terminal emulation.
