2.1 Safety Standards
The barcode positioning system BPS 37 and the optional connection units MA 4.7/MA 4D.7
have been developed, produced and tested subject to the applicable safety standards. They
correspond to the state of the art.
2.2 Intended Use
Attention!
The protection of personnel and the device cannot be guaranteed if the device is operated
in a manner not corresponding to its intended use.
Barcode positioning systems of the type BPS 37 are optical measuring systems which use
visible red laser light to determine the position of the BPS relative to a permanently mounted
barcode band.
Typically, the BPS is mounted on a (rail-)guided vehicle whose position is to be exactly
determined.
The position is determined to within a millimetre using the information of the fixed barcode
band and made available to the primary system at a suitable interface.
The optional connector and interface units MA 4.7/MA 4D.7 are intended for the easy
connection of barcode positioning systems of type BPS 37.
In particular, unauthorised uses include:
• rooms with explosive atmospheres
• operation for medical purposes
Areas of application
The barcode positioning system BPS 37 with optional connection unit MA 4.7/MA 4D.7 has
been designed particularly for the following fields of application:
• High-bay storage devices and lifting gear
• Crane systems
• Side-tracking skates
• Transfer machines
• Telpher lines

2.3 Working Safely
Attention Laser Radiation!
The barcode positioning system BPS 37 operates with a red light laser of class 2 acc.
to EN 60825-1 (2001/11). It also complies with the U.S. 21 CFR 1040 regulations for a
class II product. If you look into the beam path over a longer time period, the retina of
your eye may be damaged!
Never look directly into the beam path!
Do not point the laser beam of the BPS 37 at persons!
When mounting and aligning the BPS 37, take care to avoid reflections of the laser
beam off reflective surfaces!
The use of operating and adjusting devices other than those specified in this techni-
cal description, carrying out of differing procedures, or improper use of the barcode
positioning system may lead to dangerous exposure to radiation!
The use of optical instruments or devices in combination with the device increases
the danger of eye damage!
Adhere to the applicable legal and local regulations regarding protection from laser
beams acc. to EN 60825-1 in its latest version.
The BPS 37 uses a laser diode with low power in the visible red light range with an
emitted wavelength of about 650nm. The output power of the laser beam at the read-
ing window is at most 1.8 mW acc. to EN 60825-1 (2001/11).
The reading window is the only opening through which the laser radiation can escape
from the device. The housing of the BPS 37 is sealed and has no parts that need to
be adjusted or maintained by the user. The device must not be tampered with and
must not be changed in any way!
Notice!
It is important that you attach the sticky labels supplied to the device (notice signs and laser
emission symbol)! If the signs would be covered due to the installation situation of the
BPS 37, attach them close to the BPS 37 such that reading the notices cannot lead to look-
ing into the laser beam!

manual, is not authorised.
Safety regulations
Observe the locally applicable legal regulations and the rules of the employer’s liability insur-
ance association.

Mounting, commissioning and maintenance of the device must only be carried out by qual-
ified personnel.
Electrical work must be carried out by a certified electrician.

3.1 BPS 37 device construction
Figure 3.1: BPS 37 device construction
3.2 Application
Anywhere systems are moved automatically, it is necessary to correctly determine their
positions. This is achieved using various measurement techniques. In addition to mechan-
ical measurement sensors, optical methods are particularly well suited for determining posi-
tions as they operate without mechanical wear and slippage.
Unlike other optical measurement methods, the barcode positioning system is not restricted
to linear movements. It can also be used flexibly in curved systems. Anywhere the long-
wearing barcode band can be attached, it is possible to use the BPS to determine the posi-
tion to within a millimetre.
Guide tolerances of the system play no roll as the permitted separation between band 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 barcode band.
This essentially takes place in three steps:
1. Reading a code on the barcode band
2. Determining the position of the read code in the scanning area of the laser beam
3. Calculating of the position to within a millimetre using the code information and the
code position
The position value is then passed on via the standardised SSI interface (synchronous serial
interface) to the drive system of the vehicle for which the position is to be determined.
3.4 Advantages
• Easy installation and commissioning
• Teach function for the "zero point", i.e. it is not necessary to exactly affix the barcode
band.
• 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 barcode band 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 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 metres.
3.5 Standalone operation
The barcode positioning system BPS 37 is operated as a single "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 barcode positioning system 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.
