1. Use as safety-related component within the safety function is possible, if the component combination is designed correspondingly by the machine manufacturer.
NOTE
Do not modify or otherwise interfere with the device!
Do not carry out modifications or otherwise interfere with the device.
The device must not be tampered with and must not be changed in any way.
The use of a bar code tape not approved by Leuze is equivalent to an intervention in or
change to the device/measurement system.
The device must not be opened. There are no user-serviceable parts inside.
Repairs must only be performed by Leuze electronic GmbH + Co. KG.

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.
