Installation and adjustment of the device
4.3.1
Installing the CLV
1.
Prepare the base for mounting the CLV retainer as described in
out the accessories ready, Page 4-1
2.
Place the object with the bar code at the planned position at which the reading is to be
carried out within the visual range of the CLV (no transport movement).
3.
Depending on the scanning process align the CLV by eye to the bar code so that
−
The narrow device rear with the LED display lies approximately parallel to the bar
code surface at the line scanner
−
The wide side wall with the laser warning labels lies approximately parallel to the bar
code surface at the line scanner with oscillating mirror
Take the reading angles possibly occurring during later readings into account (refer to
).
4.
If relevant for the evaluation, take the counting direction of the code position and the
code angle into consideration (refer to
).
5.
Mount the CLV retainer on the base.
Danger of damage to the housing!
The maximum screw-in depth of the two blind hole threads M 5 amounts to 5 mm.
Longer screws damage the housing.
¾
Use screws with a suitable length.
6.
Screw the screw M 5 through the retainer into the blind hole thread of the CLV.
7.
Tighten the screws slightly.
8.
Adjust the CLV as described in
Chapter 4.3.2 Adjusting the CLV, Page 4-8
.
4.3.2
Adjusting the CLV
The "Percentage evaluation" operating mode supports adjustment of the CLV. In this ope-
rating mode the CLV displays the quality of the readings of bar codes which are placed
statically into the reading area of the CLV (no transport movement of the object). The CLV
carries out 100 scans each free running and evaluates the reading quality statically. It out-
puts the read results continuously every 2 s via the terminal interface.
The display behavior of the "Result" LED provides additional optical information on the rea-
ding quality:
•
If the LED does not light up, the CLV cannot read the bar code (reading quality< 30 %).
•
If the LED flashes, the CLV can only read the bar code badly
(reading quality30 % ... 90 %).
•
If the LED lights up continuously, the CLV is aligned optimally (reading quality > 90 %).
In the default setting the scanning frequency amounts to 600 Hz.
1.
Connect the CLV to the AMV/S 40 connection module and switch on the supply voltage
of the module (refer to
Chapter 5.5.3 Connecting the supply voltage, Page 5-4
After the start the CLV confirms the successful self-test with a beeper sound and shortly
afterwards starting of the reading mode is signaled by two consecutive sounds.
The "Device Ready" LED lights up.
