2.5 Laser safety notices
ATTENTION, LASER RADIATION – LASER CLASS 2
Never look directly into the beam!
The device satisfies the requirements of IEC 60825-1:2007 (EN 60825-1:2007) safety
regulations for a product of laser class 2 as well as the U.S. 21 CFR 1040.10 regulations
with deviations corresponding to "Laser Notice No. 50" from June 24, 2007.
Never look directly into the laser beam or in the direction of reflected laser beams!
If you look into the beam path over a longer time period, there is a risk of injury to the
retina.
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 reflec-
tive surfaces!
CAUTION! The use of operating or adjusting devices other than those specified here
or carrying out of differing procedures may lead to dangerous exposure to radiation.
Observe the applicable statutory and local laser protection regulations.
The device must not be tampered with and must not be changed in any way.

3.1 Device construction of the BPS 37
Figure 3.1: Device construction of the BPS 37
3.2 Application
Wherever systems are moved automatically, it is necessary to uniquely determine their
respective positions. This is achieved using various measurement procedures. In addition
to mechanical measurement sensors, optical methods are particularly well suited for deter-
mining positions as they operate without mechanical wear and slippage.
Unlike other optical measurement methods, the bar code positioning system is not restricted
to linear movements. It can also be used flexibly in curved systems. Anywhere the long-
wearing bar code tape can be attached, it is possible to use the BPS to determine the posi-
tion to within a millimeter.
Guide tolerances of the system play no roll as the permitted distance range between tape
and BPS allows for large deviations in distance.
3.3 Function
The BPS uses visible red laser light to determine its position relative to the bar code tape.
This essentially takes place in three steps:
Laser-beam exit
window
4x M3 mounting threads on the
rear of the device
15-pin sub-D
connector on the
bottom of the
device
Dovetail
fastening grooves

Description
10 BPS 37 Leuze electronic
1. Reading a code on the bar code tape
2. Determining the position of the read code in the scanning area of the laser beam
3. Calculating the position to within a millimeter using the code information and code
position
The position value is then passed on via the standardized SSI interface (synchronous serial
interface) to the drive system of the vehicle for which the position is to be determined.
3.4 Advantages
• Easy mounting and commissioning
• Teach function for the "zero point", i.e. it is not necessary to exactly affix the bar code
tape.
• Data output via SSI interface; BPS can be connected instead of a conventional rota-
tion encoder.
• The function of the BPS makes it possible to attach the bar code tape only at those
locations where it is necessary that the position be known exactly.
• Positioning of non-linear movements as well
• No referencing necessary following a voltage drop
• Thanks to the large scanning depth, it is possible to compensate for mechanical toler-
ances.
• It is possible to exactly determine positions from distances of 10000 meters
3.5 Stand-alone operation
The bar code positioning system BPS 37 is operated as individual "stand alone" device. The
BPS features a 15-pin sub-D connector for the electrical connection of the supply voltage,
the interface and the switching inputs.
With connection units
The connection units simplify the electrical installation of the bar code positioning systems
in stand-alone operation.
Moreover, they store the operating parameters so that the configuration data are retained
even if the BPS is replaced and can show parameters and operating data on a display
(MA 4D.7).
A listing of the available connection units and associated short descriptions can be found in
Chapter 5. Separate data sheets are available that contain further details about the connec-
tion units.
With MS 37 103 connector hood
The modular connector hood MS 37 103 is intended for the easy connection of the BPS 37
with M12 connection technology.
