Safety
Leuze electronic BPS 307i 8
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
The device is an optical measuring system which uses visible red laser light to determine its position rela-
tive to a permanently mounted bar code tape.
All accuracy details for the BPS 300 measurement system refer to the position relative to the permanently
mounted bar code tape.
Areas of application
The BPS is designed for positioning in the following areas of application:
• Telpher line
• Travel and lifting axes of high-bay storage devices
• Repositioning units
• Gantry crane bridges and their trolleys
•Elevators
2.2 Foreseeable misuse

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 figure 3.1)
• 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 posi-
tion 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

3.1.2 Performance characteristics
The most important performance characteristics of the bar code positioning system:
• Positioning with submillimeter accuracy from 0 to 10,000 m
• For the control at high traverse rates of up to 10 m/s
• Simultaneous position and speed measurement
• Working range: 50 to 170 mm; enables flexible mounting positions
• Interfaces: PROFINET fieldbus, PROFIBUS fieldbus, SSI, RS 232/RS 422, RS 485
• Binary inputs and outputs for control and process monitoring
• Configuration via webConfig tool or fieldbus
• Diagnostics via webConfig tool or optional display
• 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.
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 VDC
• 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
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 followed by the self test and the changeover to read operation. The PWR LED lights up, showing overall
readiness for operation.
NOTICE
No self-installation of the heating!
Self-installation of the heating on-site by the user is not possible.
NOTICE
Do not use ready-made cables!
It is not possible to use ready-made cables.
The current consumption of the BPS is too high for the ready-made cables.

Device description
Leuze electronic BPS 307i 14
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.
3.2 Connection technology
For the electrical connection of the BPS, the following connection variants are available:
• MS 307 connection hood with M12 connectors
• MK 307 connection hood with spring-cage terminals
• KB 307 connection hood with cable
The voltage supply (18 … 30 VDC) is connected acc. to the connection type selected.
Two freely programmable switching inputs/switching outputs for individual adaptation to the respective
application are also available here.
3.2.1 MS 307 connection hood with M12 connectors
The MS 307 connection hood features two M12 connector plugs and a Mini-B type USB socket as a
service interface for configuration and diagnostics of the BPS.
1 PWR / SW IN/OUT: M12 plug (A-coded)
2 SERVICE: Mini-B USB socket (behind protective cap)
3 HOST / BUS IN: M12 plug (B-coded), SSI
4 BUS OUT: not equipped
Figure 3.2: MS 307 connection hood, connections
3.2.2 MK 307 connection hood with spring-cage terminals
The MK 307 connection hood makes it possible to connect the BPS directly and without additional connec-
tors. The MK 307 features cable bushings in which the shielding connection for the interface cable is also
located. A Mini-B type USB socket is used for service purposes and for configuration and diagnostic of the
BPS.
The configuration switches and the integrated parameter memory for the simple replacement of
the BPS are located in the MS 307.

for service purposes and for configuration and diagnostic of the BPS.
The length of the connection cable is 3 m.
The configuration switches and the integrated parameter memory for simple replacement of the
BPS are located in the MK 307.
NOTICE

3.4 Bar code tape
3.4.1 General information
The bar code tape is available in different variants:
• BCB bar code tape with 40 mm grid
Code128 with character set C, increasing in increments of 4 (e.g., 000004, 000008, … )
• Bar code tape BCB8 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 bar code tape is delivered on a roll. A roll contains up to 200 m of BCB, with the wrapping direction
from the outside to the inside (smallest number on the outside). If more than 200 m of BCB is ordered, the
total length is divided into rolls of 200 m.
Bar code tapes with special requirements with respect to height, length and value range can be ordered
from Leuze electronic (see chapter 14.5 "Bar code tapes").
NOTICE
Value range for BCB with special requirements!
When ordering bar code tapes with special requirements, make certain that the value range contains
only values that are divisible by three (BCB8 with 30 mm grid) or four (BCB with 40 mm grid).
It may otherwise not be possible to purchase and use repair tapes.
NOTICE
Only one BCB type per system!
In a given system, use either only BCB8 with 30 mm grid or only BCB with 40 mm grid.
If different BCB types are used in one system, the BPS cannot ensure an exact position determination.
NOTICE
Configure the BPS for the used BCB type!
The used BCB type must be set in the webConfig tool with the
Tape selection parameter; see
chapter 9.3.2 "CONFIGURATION function".
On delivery, the BPS is set for BCB with a 40 mm grid.
If the BCB8 with a 30 mm grid is used, the
Tape selection must be adjusted in the BPS configuration.
If the used BCB type does not correspond to the
Tape selection configured in the BPS, exact position
determination cannot be performed by the BPS.
