2.5 Laser safety notices
Figure 2.1: Laser apertures, laser warning and information signs
ATTENTION, LASER RADIATION – CLASS 2 LASER PRODUCT
Do not stare into beam!
The device satisfies the requirements of IEC 60825-1:2014 (EN 60825-1:2014) safety regula-
tions for a product of laser class 2 as well as the U.S. 21 CFR 1040.10 regulations with devia-
tions corresponding to "Laser Notice No. 56" from May 8, 2019.
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.
Caution: Opening the device can lead to dangerous exposure to radiation
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 reflective
surfaces!
CAUTION! Use of controls or adjustments or performance of procedures other than specified
herein may result in hazardous light exposure.
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.
Repairs must only be performed by Leuze electronic GmbH + Co. KG.

3 Fast commissioning steps at a glance
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 essen-
tially 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 rela-
tive 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 23
Mounting the BPS 34 device
There are 2 different types of mounting arrangements for the BPS34:
1. Using 4 M4x6 screws on the rear of the device.
2. Using a mounting device (BT 56) on the dovetail fastening grooves.
Figure 3.1: Beam exit and device arrangement of the BPS 34
Chapter 7.1 on Page 29
NOTE
Below you will find a short description for the initial commissioning of the bar code positioning
system BPS 34. Detailed explanations of all listed points can be found throughout the
handbook.
NOTE
The installation dimensions listed in the following figure must absolutely be adhered to.
Optically, it must be ensured that the scanner has an unobstructed view of the bar code tape
at all times. Chapter 7.2 on Page 30
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.

Connecting the voltage supply and PROFIBUS
The BPS 34, in combination with an MS 34 103 or MS 34 105, is connected via M12 connectors.
Connecting the voltage supply
The voltage supply is connected via the PWR IN M12 connection.
Figure 3.2: BPS 34 with MS 34 103/MS 34 105 – PWR IN connection
Connecting the PROFIBUS
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 terminator plug (see chapter 10.3
"Accessories - Termination").
Figure 3.3: BPS 34 with MS 34 103/MS 34 105 – DP IN and DP OUT connections
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.

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 connec-
tions. For additional information, refer to Chapter 10 starting on Page 71.
Figure 4.3: Pin assignment of the BPS 34 with MS 34 103 / MS 34 105
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 accidental
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 respec-
tive connection units must have a secure electrical insulation through double insulation 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 guar-
anteed when the device is properly earthed.
ATTENTION!
Degree of protection IP 65 is achieved only if the connectors and caps are screwed into place!

ATTENTION!
If you use a sensor with a standard M 12 connector, please note the following:
Only use sensors on which the switching output does not lie on pin 2, i.e. only sensor cables
on which pin 2 is not assigned. Otherwise, the switching output is not protected against
feedback on the switching input. If the inverted sensor output lies on pin 2, for example,
erroneous behavior of the switching output will result!

5.1 MS 34 103 and MS 34 105 modular connector hoods
A modular connector hood of type MS 34 103 or MS 34 105 is part of every BPS 34. The two connector
hoods are used to connect the BPS 34 to the PROFIBUS. For this, they feature one DP IN and one
DP OUT connection each, as well as switches for address setting.
If only the connection to the PROFIBUS is intended, type MS 34 103 is sufficient.
If, in addition, a switching input/output or modular service display are to be connected, an MS 34 105 is
required. Although switching input and output are available on the PWR IN voltage supply connector, the
switching input of the MS 34 105 has the advantage that a standard sensor connector can be used.
5.1.1 General information
The modular connector hoods with integrated connectors are necessary accessories for connecting a
BPS 34 in a PROFIBUS system. On the MS 34 10x, the PROFIBUS is connected, the PROFIBUS address
set and the BPS 34 supplied with voltage.
MS 34 103
The MS 34 103 offers the following interfaces:
• PROFIBUS incoming DP IN
• PROFIBUS outgoing DP OUT
• Voltage supply PWR IN with switching input and switching output
MS 34 105
In addition to the MS 34 103, the MS 34 105 offers the following interfaces:
•For the MSD modular service display (can no longer be delivered)
• M12 connection for switching input and switching output SW IN/OUT
