2 Safety
The bar code positioning systems of the BPS 34 series and the MS 34 10x modular
connector hoods have been developed, produced and tested subject to the applicable safety
standards. They correspond to the state of the art.
2.1 Intended use
Bar code positioning systems of the BPS 34 series are optical measuring systems which use
visible red laser light to determine the position of the BPS relative to a permanently mounted
bar code tape.
The modular connector hoods MS 34 103/MS 34 105 are intended for the easy connection
of bar code positioning systems of type BPS 34 in a PROFIBUS system.
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 of the
MS 34 105.
Areas of application
The BPS 34 bar code positioning systems are designed for the following areas of applica-
tion:
• High-bay storage devices: Positioning in the travel and lifting axes
•Cranebridges and trolleys
• Side-tracking skates
•Telpherlines
•Elevators
Attention
For UL applications, use is only permitted in Class 2 circuits in accordance with the NEC
(National Electric Code).

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.
There are no user-serviceable parts inside the device.

3 Fast commissioning steps at a glance
Note!
Below you will find a short description for the initial commissioning of the bar code posi-
tioning system BPS 34. Detailed explanations of all listed points can be found throughout
the handbook.
Description of the BPS 34 functions
The BPS 34 uses visible red laser light to determine its position relative to the bar code tape.
This essentially takes place in three steps:
1. Reading a code on the bar code tape
2. Determining the position of the read code in the scanning area of the scanning beam
3. Calculating the position to within a millimeter using the code information and the code
position relative to the device's center.
The position value is then output via the interface.
Mechanical design
Mounting the bar code tape
The bar code tape is to be affixed without tension to a dust- and grease-free mounting
surface.
Chapter 6.3 on Page 30
Mounting the BPS 34 device
There are 2 different types of mounting arrangements for the BPS 34:
1. Using 4 M4x6 screws on the rear of the device.
2. Using a mounting device (BT 56) on the dovetail fastening grooves.


Leuze electronic BPS 34 9
TNT 35/7-24V
Note!
The installation dimensions listed in the following figure must absolutely be adhered to. Opti-
cally, it must be ensured that the scanner has an unobstructed view of the bar code tape at
all times. Chapter 7.2 on Page 41
Figure 3.1:Beam exit and device arrangement of the BPS 34
Chapter 7.1 on Page 38
Note!
During mounting, the following angles of inclination must be taken into account in the vertical
axis:
10° for a tape height of 47mm,
7° for a tape height of 30mm and
5° for a tape height of 25mm;
the working range of the reading field curve must also be taken into account.
Attention!
For the position calculation, the scanning beam of the BPS 34 must be incident on the bar
code tape without interruption. Ensure that the scanning beam is always incident on the bar
code tape when the system is moving.

The PROFIBUS is connected via DP IN or, in the case of a continuing network, via DP OUT.
If DP OUT is not used, the PROFIBUS must be terminated at this point with an M12 termi-
nator plug (see chapter 10.4 "Accessories - Termination").

4.3 Electrical connection
The BPS 34 can be connected via the MS 34 103/MS 34 105 using M12 connectors. For the
locations of the individual device connections, please refer to the device detail shown in
Figure 4.3.
The corresponding mating connectors and ready-made cables are available as accessories
for all connections. For additional information, refer to Chapter 10 starting on Page 95.
Attention!
Connection of the device and cleaning must only be carried out by a qualified electrician.
If faults cannot be cleared, the device should be switched off and protected against acciden-
tal use.
Before connecting the device, be sure that the supply voltage agrees with the value printed
on the name plate.
The power supply unit for the generation of the supply voltage for the BPS 34 and the
respective connection units must have a secure electrical insulation through double insula-
tion and safety transformers according to EN 60742 (corresponds to IEC 60742).
Be sure that the protective conductor is connected correctly. Fault-free operation is only
guaranteed when the device is properly earthed.

BPS 34 with MS 34 103/MS 34 105 connector hood:
Connect PE to PIN 5 of the M12 connector PWR IN for voltage supply!
Note!
Programming of the switching input/switching output is performed via module 7 (Switching
input) and module 8 (Switching output). For further information, see also Chapter 8.1.7.7,
Page 60 et seq.
Note!
The switching input/switching output of the PWR IN plug connection is identical to the SWIN
switching input and SWOUT switching output of the SW IN/OUT plug connection on the
MS 34 105.
Attention!
Degree of protection IP 65 is achieved only if the connectors and caps are screwed into
place!
