Do not point the laser beam of the device at persons!
Interrupt the laser beam using a non-transparent, non-reflective object if the laser beam is
accidentally directed towards a person.
When mounting and aligning the device, avoid reflections of the laser beam off reflective sur-
faces!
CAUTION! Use of controls or adjustments or performance of procedures other than specified
herein may result in hazardous light exposure.
Observe the applicable statutory and local laser protection regulations.
The device must not be tampered with and must not be changed in any way.
There are no user-serviceable parts inside the device.
Repairs must only be performed by Leuze electronic GmbH + Co. KG.
If the scanner motor fails during the emission of laser radiation, the limit value of laser class 2
in accordance with IEC 60825-1:2014 could be exceeded. The device has safeguards to
prevent this occurrence.
If the emitted laser beam is at a standstill, immediately disconnect the faulty bar code reader
from the voltage supply.
The BPS 8 emits scanned optical radiation at a wavelength of 655 nm (red).
Looking at the device's mirror and operating at the lowest scanning rate (500 scans/s) at a
viewing distance of 100 mm results in pulses with a pulse duration shorter than 420 µs on
the retina of the eye. The total pulse peak power at the exit window is less than 1.7 mW.
The average laser power is less than 1 mW in accordance with laser class 2 acc. to
IEC 60825-1:2014

Bar code tape
Leuze electronic GmbH + Co. KG BPS 8 18
5 Bar code tape
5.1 General information
The bar code tape is available in different variants:
•BCB G40 ... bar code tape with 40 mm grid, Code128 with character set C, increasing in increments
of 4 (e.g., 000004, 000008, … )
•BCB G30 ... bar code tape with 30 mm grid, Code128 with character set C, increasing in increments
of 3 (e.g., 000003, 000006, … )
A bar code tape consists of a sequence of individual position bar codes in one of the two grids. Defined
cut marks are provided for cutting the BCB.
The bar code tape is delivered on a roll. A roll contains up to 300 m of BCB. The BCB always starts with
the lowest position value at the outside of the roll (this is the value ’000000’ for standard tapes). The BCB
ends at the inside on the wrapping core with the largest position value. If more than 300 m of BCB is
ordered, the total length is divided into rolls of 300 m.
CAUTION
Bar code tape!
BPS 8 is set for bar code tape BCB G30 ... with a 30 mm grid by default.
The BPS 8 can be configured for position measurement with a 40 mm bar code tape
(BCB G40 ...) with the BPS Configuration Tool.
NOTE
Special tapes are produced according to customer specifications.
A special tape is characterized by the following features:
• The initial value as well as the final value of the tape (dependent on the BCB G30 ... grid
dimension) according to customer specifications.
• Special tapes are printed below the bar code with the corresponding position value.
• Tape heights are available in millimeter increments in the range from 20 mm to 140 mm.
• The maximum tape length is 10,000 m, the maximum position value is 9999.99 m.
• Special tapes longer than 300 m are delivered wound on multiple rolls.
An entry wizard is available for special tapes on the Leuze website under the "BPS 8 - Acces-
sories" heading. 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.
NOTE
Only one BCB type per system!
In a given system, use either only BCB G30 ... with 30 mm grid or only BCB G40 ... with
40 mm grid.
If different BCB grids are used in one system, the BPS cannot ensure an exact position deter-
mination.

Standard BCB G30 ... bar code tapes are available in various length increments in the following heights:
•47mm
•25 mm
Special BCB G30 ... tapes are available in mm height increments between 20 and 140 mm.
An entry wizard is available for special tapes on the Leuze website under devices "BPS 8 - Accessories".
The entry wizard provides support when entering the individual pieces of tape data and creates a query or
order form.
5.2 BCB G30 ... control bar code MVS
With the help of control bar codes that are affixed on top of the bar code tape at appropriate positions, func-
tions in the BPS can be activated or deactivated, e.g. precise, reproducible switching between different
BCB value ranges at switches.
Code type Code128 with character set B is used for the control bar code.
The MVS label is a control bar code for the precise, reproducible switching of position values from a
preceding to a subsequent bar code tape. The subsequent bar code tape begins with another, new value
range.
The changeover between the different value ranges of the two BCBs occurs independent of the direction
of travel in the center of the MVS control bar code.
Arrangement of the control bar codes
The control bar code is attached in such a way that it replaces one position bar code or seamlessly
connects two bar code tapes with different value ranges to one another (see figure 5.2).
NOTE
With a standard bar code tape and repair tape with 30 mm grid, the printed numerical values
are divisible by three without a remainder.

NOTE
If, upon reaching the the center of the MVS control bar code, the BPS 8 does not detect the
value range of the subsequent BCB in the scanning beam, the position value of the first BCB
section is still output for half of the label width starting from the center of the MVS control bar
code.

Figure 5.2: Arrangement of the MVS control bar code
The control bar codes are simply affixed over the existing bar code tape.
NOTE
Distance between two control bar codes!
Make certain that there is only one control bar code (or marker bar code) in the scanning
beam at a time.
The minimum distance between two control bar codes is determined by the distance between
the BPS 8 and bar code tape and the resulting length of the scanning beam.
NOTE
Grid dimension of control/marker bar code!
The control/marker bar code must match the selected grid of the bar code tape used. If a
30 mm grid is used (default), then the control/marker bar code must also be inserted in the
30 mm grid. With a 40 mm grid, a 40 mm control/marker bar code is used.
NOTE
Keep the gap between the BCBs that are switched between as small as possible.
