2 Safety
This sensor was developed, manufactured and tested in line with the applicable safety standards. It corre-
sponds to the state of the art.
2.1 Intended use

position relative to a permanently mounted barcode tape.
All accuracy details for the BPS3000i measurement system refer to the position relative to the permanently
mounted bar code tape.
CAUTION
Use only approved bar code tapes!

3 Device description
3.1 Device overview
3.1.1 General information
The BPS3000i barcode positioning system uses visible red laser light to determine its position and its
speed value relative to a barcode tape that is affixed along the travel path. This takes place in the following
steps:
• Read a code on the barcode tape (see following figure)
• Determine the position of the read code in the scanning beam
• Calculate the position to within less than a millimeter using the code information and the code position
relative to the device's center.
The position and speed values are then output to the controller via the host interface.
The BPS consists of device housing and interface connection hood for the connection to the control. The
connection hood must be ordered separately.
The following connection hoods are available for the connection of the PROFINET interface:
• MS3048 connection hood with M12 connectors
• MK3048 connection hood with spring-cage terminals

3.4 Bar code tape
3.4.1 General information
A barcode tape with 40mm grid is required for operation of a BPS3000i bar code positioning system.
A barcode tape consists of a sequence of individual position labels. Defined cut marks are provided be-
tween the individual bar codes for cutting the BCB.
The BCB is delivered on a roll. A roll contains up to 300m of BCB, with the wrapping direction from the out-
side to the inside (smallest number on the outside). If more than 300m of BCB is ordered, the total length
is divided into rolls of max. 300m.
Standard bar code tapes in fixed length increments as well as special bar code tapes with custom tape
start value, tape end value, custom length and height can be found on the Leuze website in the acces-
sories for the BPS3000i devices.
An entry wizard is available for special bar code tapes on the Leuze website under devices BPS3000i - Ac-
cessories tab. The entry wizard provides support when entering the individual pieces of tape data and cre-
ates a query or order form with the correct part number and type designation.

3.4.2 Twin tapes
Designation: BCBG40…TWIN
Twin tapes are jointly manufactured barcode tapes with the same value range.
NOTICE
A twin tape always consists of two barcode tapes!
ÄWhen ordering a twin tape, two barcode tapes are always included with an order.
Twin tapes are used if positioning with two barcode tapes is necessary, e.g., with crane systems or eleva-
tors.
Because they are manufactured jointly, both tapes have the same length tolerance. As a result, differences
in length and code position are minimal. By having the same code position on both tapes, improved syn-
chronization can be achieved during positioning compared to barcode tapes that are manufactured sepa-
rately.

2 Twin barcode tape2
Fig.3.8: Twin bar code tape with double numbering
NOTICE
Twin tapes are always delivered in pairs on two rolls.
If twin tapes are replaced, both tapes are to be replaced.
An entry wizard for twin tapes with custom tape start value, tape end value, custom length and
height is available on the Leuze website under devices BPS3000i - Accessories tab. The entry
wizard provides support when entering the individual pieces of tape data and creates a query or
order form with the correct part number and type designation.

4 Functions
4.1 Evaluation of the reading quality
NOTICE
Output of the reading quality
The bar code positioning system can diagnose the reading quality from the arrangement of the
BPS relative to the bar code tape.
ÄThe reading quality is output in % values.
ÄIn spite of optimum operating conditions, the reading quality may be slightly below 100%.
This does not indicate a defect of the BPS or of the bar code tape.
NOTICE
The warning threshold preset ex works for a reading quality < 60% as well as a switch-off
threshold for a reading quality < 30% corresponds to Leuze's experience in a typical applica-
tion.
For applications that involve an intentional interruption of the bar code tape (switches, expan-
sion gaps, vertical slopes/descents), the preset limit values can be adapted to the respective ap-
plication.
The reading quality is dependent on several factors:
• Operation of the BPS in the specified depth of field
• Number of bar codes in the transmitted beam
• Number of bar codes in the reading field
• Soiling of the barcode
• Traverse rate of the BPS (number of bar code symbols within the time window)
• Ambient light incident on the bar code and on the optics (glass exit window) of the BPS
The reading quality is affected, in particular, in the following cases:
• Switches, expansion gaps and other transition points at which the bar code tape is not affixed interrup-
tion-free.
• Vertical travel if at least two bar code symbols are not completely in the reading field of the sensor at
any given point in time.
• Vertical curve in which the bar code tape was separated at the marked cut marks for adapting to the
curve.
NOTICE
If the reading quality is influenced by the factors listed above, the reading quality can be re-
duced to as low as 0%.
ÄThis does not mean that the BPS is defective, but rather that the reading quality characteris-
tics are reduced to as low as 0% in the given arrangement.
ÄIf, at a reading quality of 0%, a position value is output, it is correct and valid.
The parameters for the evaluation of the reading quality are set in the interface-specific configuration (see
chapter 8.4.13 "Module24–Reading quality").
The evaluation of the reading quality provides the following information, e.g.:
• The reading quality is constantly bad: Soiling of the BPS optics
• The reading quality is always poor at certain position values: Soiling of the bar code tape

5 Applications
Wherever systems are moved automatically, it is necessary to uniquely determine their respective posi-
tions. In addition to mechanical measuring sensors, optical methods are particularly well suited for position
determination as they can be used to determine position without mechanical wear and slippage.
Compared to common optical measurement techniques, the Leuze Barcode Positioning System (BPS) is
able to measure a position with absolute sub-millimeter accuracy, i.e. independent of reference points. As a
result, it is able to provide a unique position value at any time. With the highly flexible and hard-wearing
BarCode Tape (BCB), the system can even be used without problem in systems with curves or guide toler-
ances. And this at lengths of up to 10,000meters.
The barcode positioning system convinces with a variety of advantages:
• The laser simultaneously scans multiple barcodes and, as a result, is able to determine the position
with sub-millimeter precision. The wide reading field makes accurate position determination possible
even in the event of minor damage to the tape.
• With the systems' flexible depth of field, it is also possible to bridge over mechanical deviations.
• Due to the large reading distance combined with the great depth of field, a large opening angle and a
very compact construction, the device is ideally suited for the conveyor and storage technology market.
• Using a mounting device, the BPS can be mounted with millimeter accuracy with just one screw. If
mounted using a mounting device, a new device is automatically aligned correctly should it be neces-
sary to exchange a device (easy-mount).
• The unique encoding of the position value on the barcode tape allows the system to be put back into
operation without problem even after a brief voltage drop without, e.g., needing to utilize a reference
point.
• The Leuze barcode tape is very robust, highly flexible and, thanks to the self-adhesive back, can be
easily integrated into your overall mechanical system. It can be fit optimally to both vertical as well as
horizontal curved paths and thereby reliably facilitates trouble-free and reproducible measurement at
any point in your system with sub-millimeter accuracy.
Typical applications for the BPS include:
• Stacker crane (see chapter 5.1 "High-bay storage device")
• Electrical monorail system (see chapter 5.2 "Electrical monorail system")
• Gantry cranes (see chapter 5.3 "Gantry cranes")
