3 Device description
3.1 Device overview
3.1.1 General information
The BPS 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
BPS can optionally be delivered with display and optics heating.
The following connection hoods are available for the connection of the SSI interface:
• MS307 connection hood with M12 connectors
• MK307 connection hood with spring-cage terminals
• KB307 connection hood with cable

• Diagnosis via webConfig tool or optional display

Device description
Leuze electronic GmbH + Co. KG BPS 307i 11
• Optional model with display
• Optional model with heating for use to -35°C
3.1.3 Accessories
Special accessories are available for the bar code positioning system. The accessories are optimally
matched to the BPS:
• Highly flexible, scratch-, smudge- and UV-resistant barcode tape
• Mounting devices for precise mounting with one screw (easy-mount)
• Modular connection technology via connection hoods with M12 connectors, spring-cage terminals or
with cable
3.1.4 Device model with heating
The barcode positioning system is optionally available as a model with integrated heating. In this case,
heating is permanently installed ex works.
NOTICE
No self-installation of the heating!
ÄSelf-installation of the heating on-site by the user is not possible.
The heating consists of two parts:
• Front cover heater
• Housing heater
Features of the integrated heating:
• Extends the application range of the BPS to -35°C
• Supply voltage 18…30 V DC
• BPS release through an internal temperature switch (start-up delay of about 30min for 24VDC and
minimum ambient temperature of ‑35°C)
• Required conductor cross-section for the power supply: At least 0.75mm2
NOTICE
Do not use ready-made cables!
ÄIt is not possible to use ready-made cables.
The current consumption of the BPS is too high for the ready-made cables.
Function
When the supply voltage is applied to the BPS, a temperature switch initially only supplies the heating with
current (front cover heater and housing heater). During the heating phase (around 30min), when the inside
temperature rises above 15°C, the temperature switch connects the BPS to the supply voltage. This is fol-
lowed by the self test and the changeover to read operation. The PWRLED lights up, showing overall
readiness for operation.
When the inside temperature reaches approx.18°C, another temperature switch turns the housing heater
off and, if necessary, back on again (if the inside temperature drops below 15°C). This does not interrupt
the read operation.
The front cover heater remains activated until an inside temperature of 25°C is reached. At temperatures
above this, the front cover heater switches off and, with a switching hysteresis of 3°C, back on again at an
inside temperature below 22°C.

Display during device start-up
During device start-up, a start-up display first appears which is briefly followed by the display with the ver-
sion information.
The standard display after starting up the BPS is Position Value.
3.4 Bar code tape
3.4.1 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 labels in one of the two grids. Defined cut
marks are provided 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300 devices.
An entry wizard is available for special bar code tapes on the Leuze website under devices BPS300 - 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.
NOTICE
Only one BCB type per system!
ÄIn a given system, use either only BCBG30… with 30mm grid or only BCBG40… with
40mm grid.
If different BCBG30… or BCBG40… models are used in one system, the BPS cannot en-
sure an exact position determination.

Device description
Leuze electronic GmbH + Co. KG BPS 307i 18
NOTICE
Configure the BPS for the used BCB type!
ÄThe used BCB type must be set in the webConfig tool with the Tape selection parameter;
see chapter 9.3.4 "CONFIGURATION function".
ÄOn delivery, the BPS is set for BCBG40… with a 40mm grid.
If the BCBG30… with a 30mm grid is used, the Tape selection must be adjusted in the
BPS configuration.
ÄIf the used BCB type does not correspond to the Tape selection configured in the BPS, ex-
act position determination cannot be performed by the BPS.

3.4.2 Control bar codes
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., for changing various position values at switches.
Code type Code128 with character setB is used for the control barcode.
MVS label
Designation: BCBG40…MVS or BCBG30…MVS
The MVS label is a control barcode for the direction-independent switching of the position values from one
barcode tape to another in the middle of the control barcode label.
If, upon reaching the changeover position in the middle of the MVS label, the BPS does not detect the new
BCB section in the scanning beam, the position value of the first BCB section is still output after the middle
of the MVS label for half of the label width.

MV0 label
Designation: BCBG40…MV0 or BCBG30…MV0
The MV0 label is a control barcode for the direction-independent switching of the position values from one
barcode tape to another in the middle of the control barcode label.
If, upon reaching the changeover position in the middle of the MV0 label, the BPS does not detect the new
BCB section in the scanning beam, no position is output after the middle of the MV0 label for.

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 con-
nects two barcode tapes with different value ranges to one another.
A position label does not need to follow immediately after the MVS or MV0 control bar code. For an uninter-
rupted measurement value determination, a gap less than or equal to one label width (40 mm) may be
present between the control bar code and the subsequent position label.
