Device description
Leuze electronic GmbH + Co. KG BPS 338i 11
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 EtherCAT interface:
• MS338 connection hood with M12 connectors
• MK338 connection hood with spring-cage terminals
• ME338103 connection hood with cables with M12 connector

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: Ethernet
• Binary inputs and outputs for control and process monitoring
• Configuration via webConfig tool or EtherCAT service data objects (SDOs)
• Diagnosis via webConfig tool or optional display

Device description
Leuze electronic GmbH + Co. KG BPS 338i 12
• 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 cables
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.

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 ap-
plication are also available here.
3.2.1 MS338 connection hood with M12 connectors
The MS338 connection hood features three M12 connector plugs and a Mini-B type USB socket as a ser-
vice interface for configuration and diagnosis of the BPS.
NOTICE
The integrated parameter memory for the simple replacement of the BPS is located in the con-
nection hood.
In the integrated parameter memory, the settings of the BPS and the network address are
stored temporarily. Upon device exchange, they are automatically transmitted to the new device.
NOTICE
Network interruption with EtherCAT in a linear topology!
ÄIn the event of a device exchange, the EtherCAT network is interrupted at this location.
ÄThe EtherCAT network is interrupted if the BPS is unplugged from the connection hood.
ÄIf there is no voltage supply for the BPS, the EtherCAT network is interrupted.

Cable fabrication and shielding connection
ÄRemove approx.78mm of the connection cable sheathing. 15mm of sheath of the shielded line must
be freely accessible.
ÄLead the individual wires into the terminals according to the diagram.
NOTICE
Do not use wire-end sleeves!
ÄWhen fabricating cables, we recommend against using wire-end sleeves.
