Counting direction of the reading angle
The device can scan and decode several bar codes at each reading.
The device determines the location-specific read diagnostics data per bar code and
optionally outputs these data in the read result:
Reading angle (RA value)
■
This value specifies the angle at which the deflected scanning beam detects the
bar code center with the red scan line in the scan plane. This value is within the
aperture angle of the device.
By determining the respective RA value, identical bar codes (code type, code length,
and data content) can be separated, and the bar code data can be assigned based on
its position on the object.

Mounting device
Device with heating:
NOTE
Do not expose the device to strong air movement, e.g. a ventilation system. The device
may otherwise not be able to provide the required heating power. If necessary, shield
the device from air movement with suitable means.
NOTICE
Risk of damage to components
Do not move the following components when the ambient temperature is below 0 °C:
•
Connecting cables
•
Swivel connector on device (type-dependent)
•
Configuration switch in the optional connection module
General:
NOTICE
Risk of damage to the device
the device will be damaged if the tightening torque of the mounting screws is too high
or if the maximum screw-in depth of the blind hole threads is exceeded.
b
Observe maximum tightening torque.
b
Use suitable mounting screws for the blind hole threads of the device. Observe the
maximum screw-in depth.
