2.1 Safety Standards
The barcode positioning system BPS 34, the modular hoods with integrated connectors
MS 34 103/MS 34 105, and the optional modular service display MSD 1 101 have been
developed and manufactured under observation of the applicable European standards and
directives.
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 34 are optical measuring systems which use
visible red laser light to determine the position of the BPS relative to a permanently mounted
barcode band.
The modular hoods with integrated connectors MS 34 103/MS 34 105 are intended for the
easy connection of barcode positioning systems of type BPS 34 in a Profibus system and
for the setting of the respective Profibus address (see chapter 6.3 "Address setting").
The modular service display MSD 1 101, which is optionally available, displays operational
data of the BPS 34 and is used as a simple means of access to the service interface.
In particular, unauthorised uses include:
• rooms with explosive atmospheres
• operation for medical purposes
Areas of application
The barcode positioning system BPS 34 has been developed in particular for the following
areas 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 34 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 34 at persons!
When mounting and aligning the BPS 34, 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 34 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 34 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 34, attach them close to the BPS 34 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 34 device construction
Figure 3.1: BPS 34 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.

Leuze electronic Description

TNT 35/7-24V
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 transferred to the controller via the Profibus DP.
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 the integrated Profibus DP.
• 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 Modular hoods with integrated connectors MS 34 103/MS 34 105
The modular hoods with integrated connectors are necessary accessories for connecting a
BPS 34 in a Profibus system. They are used to feed through the Profibus connections, set
the Profibus address, and supply voltage to the BPS 34.
MS 34 103
The MS 34 103 offers the following interfaces:
• Profibus In (DP IN)
•ProfibusOut(DPOUT)
• voltage supply (PWR IN)
MS 34 105
In addition, the MS 34 105 offers the following interfaces:
• for the modular service display (MSD)
• switching inputs and outputs (SW IN/OUT)
Please refer to chapter 5 for further information regarding the modular hoods with integrated
connectors.

3.6 Modular Service Display MSD 1 101
The modular service display is used to display the reading and operational data on the one
hand, and as simple access to the service interface on the other. The RS 232 service inter-
face of the BPS 34 is tapped in this case and is made available at the 9-pin sub D connector
of the MSD (for further information see page 15).
To connect to the MS 34105, an 8-pin cable (M12) with a length of 2m is used (see chapter
5 "Accessories / Order Designation").
Using the maintenance display, new settings for the BPS can be trialled quickly and easily,
without having to project these settings via the Profibus. Once the optimal settings have
been found, which are to be adopted for the standard operation, these must be included in
the project in order for them to become permanently active.
Notice!
The BPS has a parameter memory in which all project settings are stored. When switching
back from maintenance mode to standard mode, the settings specified in maintenance
mode are overwritten by the settings stored in the parameter memory.

4.2 LED indicators
BPS 34
A BPS 34 internal green LED indicates in the reading window whether or not the supply
voltage is present.
MS 34 103 / MS 34 105
On top of the modular hood with integrated connectors a red/green status LED is located
between the M12 connectors DP IN and DP Out. It indicates the state of the Profibus
connection.
4.3 Device Construction and Components
Two models of the BPS 34 are available: BPS 34 S M 100 without optics heating
BPS 34 S M 100 H with optics heating
A modular hood with integrated connectors of the type MS 34 103 or MS 34 105 is always
part of a BPS 34. The purpose of both hoods is to connect the BPS 34 to the Profibus. For
this, they feature one Profibus IN and one Profibus OUT connection each, as well as an
internal switch for address setting.
If only the connection to the Profibus is intended, type MS 34 103 is sufficient.
If, in addition, switching input and output or a modular service display are to be connected,
an MS 34 105 is required. Although switching inputs and outputs are available on the
voltage supply connector, the switching inputs of the MS 34 105 have the advantage that a
standard sensor connector can be used.
