Maximum permissible read angles between BCL 504
i
and barcode
The optimum alignment of the BCL 504
i
is accomplished when the scan line scans the code
bars almost at a right angle (90°). All read angles that are possible between the scan line
and barcode must be taken account (figure 6.7).
Figure 6.7:
Reading angle for the line scanner
α
Tilt - max. 45°
β
Pitch - max. 45°
γ
Skew - max. 45°
In order to avoid total reflection, the skew
γ
should be greater than 10°

Attaching laser warning sign
Attention Laser!
Follow the safety notices in chapter 2.
ª
It is important that you attach the sticky labels supplied to the device (laser warning signs
and laser emission symbol)! If the signs would be covered due to the installation situation
of the BCL 504
i
, attach them instead in the immediate vicinity of the BCL 504
i
in such a
way that it is not necessary to look into the laser beam when reading the notices!

Cleaning
ª
Clean the glass window of the BCL 504
i
with a soft cloth after mounting. Remove all
packaging remains, e.g. carton fibres or Styrofoam balls. In doing so, avoid leaving fin-
gerprints on the front cover of the BCL 504
i
.
Attention!
Do not use aggressive cleaning agents such as thinner or acetone for cleaning the device.
