1.7 PHOTOELECTRIC SENSOR
The optional Photoelectric Sensor is used in barcode scanner systems to detect the
presence of an item in the scanning area.
The photoelectric sensor is used in singulated systems where the packages are separated
by an open space between the trailing edge of one package and the leading edge of the
next. The photoelectric sensor, along with the encoder, enables a programmable transmit
point at a defined distance from the sensor. Without the photoelectric sensor, the barcode
scanner can be run in continuous mode. See 4.5.1 Modify Settings | Global Settings |
Operating Mode.
Depending on the application, these devices may need to be configured differently. While the
photoelectric sensor and tachometer work well with belt conveyors, a special configuration is
needed for tilt-tray and cross-belt sorter applications. See section 3.10 for wiring options.

1.8 ENCODER (TACHOMETER)
The tachometer provides a continuous pulse to the system, which provides feedback on
conveyor speed and transmit point, and can be used to help track the package position along
the length of the conveyor. See section 3.11 for wiring options.

MA Series are industrial connection boxes that can be used to connect the barcode scanners
to an encoder/tachometer, photoelectric sensor, serial devices, relays, or other peripherals.
The MA 900 includes a Backup Module, which allows easy parameter restore and backup
operations. The Backup Module also provides an easy way to upload existing parameters to
a replacement barcode scanner when necessary. See section 3.9.1 for wiring options.

The MSC 900 Controller offers all the necessary functions to make the phases of installation,
setup, testing, and maintenance of the omni-directional reading array or tunnel easy and
quick.
The MSC 900 Controller is fully compatible with BCL 900i scanner and its sturdy mechanical
structure makes the MSC 900 Controller the ideal solution for industrial environments. The
Controller allows connection to the Trigger and Encoder/Tachometer. PNP inputs are
available via M12 circular connectors, placed on the lower front panel (see section 3.11).

IMPORTANT: Application-specific drawings and documents provided by
Leuze electronic supersede any contradictory content in this manual.
NOTE: Refer to the Chapter 3 Electrical Installation and Reference
Documentation for details on connecting your barcode scanners to other
devices in the system.
WARNING: Electrical Installation by Qualified Service Technicians Only!
Procedures may involve exposure to high-voltage. A trained and authorized
technician must perform these procedures. Do not attempt to perform any
electrical installation procedures unless you are a trained technician.
IMPORTANT: BCL 900i barcode scanners contain electronics that may be
affected by electrostatic discharge (ESD). To prevent personal injury or
damage to the unit, please follow the safety precautions and warnings found
in the References section at the beginning of this manual. Failure to follow
these precautions may void your warranty.
WARNING: When installing several scanners, take care to position them so
that no laser beam enters the reading window of other scanners. This
condition could occur more frequently for side mounted applications. If these
precautions are not followed, read rate could be negatively affected. To
resolve this problem, it is sufficient to slightly change the inclination and
position of one of the two scanners involved if possible.
2 MECHANICAL INSTALLATION
2.1 PREPARING FOR MECHANICAL INSTALLATION
Before mounting any components, please do the following:
Read all instructions before beginning your installation.
Define and confirm the accuracy of your application’s requirements and structure
position, especially the height of the conveyor from the floor.
Review all installation-specific drawings provided with your equipment.
Review and plan the mechanical installation of all devices used in your application. Be
sure to allow adequate clearance for maintenance.
Review and plan the power requirements for your application.
Check the contents of the shipping cartons against the packing list.

2.4 WHAT YOU NEED TO KNOW ABOUT YOUR APPLICATION
To assure you get optimal performance out of your BCL 900i, it must be installed to meet the
complete needs of your application. Therefore, take the time to learn the details of your
application. The better you know your application, the easier it is to apply the BCL 900i’s
capabilities to meet your application’s requirements.
Below is what you will need to know before you can begin installation:
Conveyor Specifications
Conveyor type: Belt, tilt-tray, cross belt, other?
What is the conveyor width?
What is the conveyor speed?
Does conveyor speed vary or is it constant?
Product Specifications
Are the packages being transported always singulated (not touching) or non-
singulated (possibly touching)?
How many different product sizes may be involved?
Are products justified: toward/away from reader, centered, or variable?
Application Specifications
How will the barcode information be used in your application?
What are your communication requirements?
While it is nearly impossible to cover all application configurations, the next several pages
provide the basics on determining how to mechanically install your BCL 900i. If you need
additional assistance, feel free to contact your sales representative or customer service
(www.leuze.de).

2.5.4 General Mounting Guidelines
It is important that you follow these general precautions when installing, setting up, operating,
maintaining, troubleshooting, or replacing any Leuze electronic products, parts or related
equipment.
As you plan and install your BCL 900i barcode scanning system application, be sure to keep
the following guidelines in mind:
All mounting structure assembly and equipment installation can be performed by one
installer.
Determine the proper orientation and position of the barcode scanner.
Leave adequate clearances (approximately 300 mm [12 inches]) for wiring.
Route wires carefully to reduce or minimize electrical noise. When power and
communication wiring must cross, make their intersection perpendicular.
Proper grounding limits the effects of noise due to Electromagnetic Interference (EMI).

2.5.5 Mounting Structure Considerations
Your first task is to mount your BCL 900i barcode scanner.
Your mounting structure must provide the following capabilities:
It is adjustable enough for you to move your unit to the optimum position for proper
scanning.
It allows a technician access to the barcode scanner while it is mounted.
It must be as vibration free as possible so as not to affect the scanning accuracy.
It is constructed of steel or aluminum.
It provides approximately 300 mm [12 inches] minimum clearance on all sides. This
clearance is necessary to provide proper ventilation, allow access to all panels of the
barcode scanner, and allow room for proper servicing.

2.5.6 Mounting the Scanner
The BCL 900i can be installed to operate in any position. There are 12 screw holes (M6 X 8)
on the sides of the scanner for mounting. The diagram below can be used for installation;
refer to reading diagrams (See 5.10) and any application drawings for correct positioning of
the scanner with respect to the reading zone and scanner orientation.

Mounting position
The BT 900 included with the BCL 900i scanner allows it to be installed in the most suitable
position for your application. The BT 900 is mounted to the scanner as shown below:

Figure 11: BCL 900i mounting angles
If the BCL 900i needs to be mounted at a 5-degree angle or within 5-degrees of the angles
shown in Figure 11: BCL 900i mounting angles (+/- 5, +/-25, or +/-35-degrees), mount it to
the opposite end of the BT 900 as shown below:

2.5.7 Positioning the Scanners
The BCL 900i barcode scanners are able to decode barcode labels at a variety of angles;
however significant angular distortion may degrade reading performance.
When mounting the scanners, take into consideration these three ideal label position angles:
Pitch 0°, Skew 0° to 45° and Tilt 0°.
Follow the suggestions for the best orientation:
