Mounting the BCL 8
There are three basic mounting arrangements for the BCL 8 (see Chapter 4.3):
• using the dovetail fittings and the corresponding mounting accessory BT 8
-
0.
• using the mounting threads on the back- and underside of the devices.
• using the two
4.4mm through holes.
Mounting the MA 8.1 connection unit
You can mount the MA 8.1 connection unit according to your needs by using the two bore holes. Subse
-
quently, connect the BCL 8 with the connection unit via the respective cable (see separate data sheet for
MA 8.1).

Selecting a mounting location
In order to select the right mounting location, several factors must be considered:
• size, orientation, and position tolerance of the bar codes on the objects to be scanned.
• the reading field of the BCL 8 in relation to the bar code module width.
• the resulting minimum and maximum read distance from the respective reading field (for specific
information, please refer to Chapter 4.4).
• alignment of the bar code reader for avoiding reflections.
• distance between BCL 8 and host system with respect to the interface.

Mounting location
When choosing the mounting location, observe the following:
• maintaining the required environmental conditions (temperature, humidity).
• possible soiling of the reading window due to liquids, abrasion by boxes, or packaging material resi
-
dues.
• lowest possible chance of damage to the scanner by mechanical collision or jammed parts.
• possible extraneous light influence (no direct sunlight).
NOTE
The best read results are obtained when
• the reading distance lies in the middle area of the reading field.
• there is no direct sunlight and extraneous light is avoided.
• the bar code labels are of good print quality and have good contrast ratios.
• you do not use high-gloss labels.
• the bar code is moved past the reading window with an angle of rotation > approx. 15°.
• the laser beam is narrowed down for its respective reading task in order to avoid reflections
on shiny components.
NOTE
With front beam exit, the beam exit on the BCL 8 is nearly vertical to the reading window; with
lateral beam exit, the beam exit is at 15° from vertical. The bar code label must be rotated by
> 10° to avoid a total reflection of the laser beam in the case of glossy labels.
