3.1 Device construction of the BPS 37
Description
Figure 3.1: Device construction of the BPS 37
3.2 Application
Wherever systems are moved automatically, it is necessary to uniquely determine their
respective positions. This is achieved using various measurement procedures. In addition
to mechanical measurement sensors, optical methods are particularly well suited for determining positions as they operate without mechanical wear and slippage.
Unlike other optical measurement methods, the bar code positioning system is not restricted
to linear movements. It can also be used flexibly in curved systems. Anywhere the longwearing bar code tape can be attached, it is possible to use the BPS to determine the position to within a millimeter.
Guide tolerances of the system play no roll as the permitted distance range between tape
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 bar code tape.
This essentially takes place in three steps:
Leuze electronic BPS 37 9
TNT 35/7-24V
Description
1. Reading a code on the bar code tape
2. Determining the position of the read code in the scanning area of the laser beam
3. Calculating the position to within a millimeter using the code information and code
position
The position value is then passed on via the standardized SSI interface (synchronous serial
interface) to the drive system of the vehicle for which the position is to be determined.
3.4 Advantages
• Easy mounting and commissioning
• Teach function for the "zero point", i.e. it is not necessary to exactly affix the bar code
tape.
• Data output via SSI interface; BPS can be connected instead of a conventional rotation encoder.
• The function of the BPS makes it possible to attach the bar code tape 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 a voltage drop
• Thanks to the large scanning depth, it is possible to compensate for mechanical tolerances.
• It is possible to exactly determine positions from distances of 10000 meters
3.5 Stand-alone operation
The bar code positioning system BPS 37 is operated as individual "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 bar code positioning systems
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 connection units.

6.2.1 Device arrangement
Selecting a mounting location
In order to select the right mounting location, several factors must be considered:
• The scanning range determined from the scanning curve must be adhered to at all
areas at which a position determination is to be made
• The BPS should be mounted inclined by 10° in the vertical axis towards the bar code
tape to ensure that the read results are reliably obtained even if the bar code tape is
soiled.
Note!
The best functionality is obtained when:
• The BPS is guided parallel to the tape
• The permitted working range is not exited
Note!
On the BPS 37, the beam is not emitted perpendicular to the housing cover, but with an
angle of 10° towards the top. This angle is intended to prevent total reflection on the bar
code tape.

Mounting location
When choosing the mounting location, observe the following:
• maintaining the required environmental conditions (humidity, temperature),
• possible soiling of the reading window due to liquids, abrasion by boxes, or packaging
material residues.
• lowest possible chance of damage to the scanner by mechanical collision or jammed
parts.

Commissioning
7 Commissioning
7.1 Measures to be performed prior to the initial commissioning
Before commissioning, familiarize yourself with the operation and configuration of the
device(s).
Before switch-on, recheck all connections and ensure that they have been properly
made.
7.2 Function Test
"Power On" test
After connecting the operating voltage, the BPS 37 performs an automatic "Power On" function test. Subsequently, the green LED lights up in the optical window of the BPS 37.
Interface
Proper function of the interface can be most easily tested in service operation using the
service interface with the "BPSConfig" configuration software and a notebook computer. For
order numbers, see Table 5.1 on page 17.
Online commands
Using the online commands, important device functions can be checked, e.g. proper functioning of the laser.
Problems
If a problem occurs that cannot be rectified even after checking all electrical connections and
settings on the devices and on the host, please contact the closest Leuze service organization (see back page of this operating manual).
7.3 Setting the parameters
You have now commissioned the BPS. Usually, you will have to configure it before you can
use it. Using the parameter options made available by the BPS, you can configure the BPS
to suit your individual area of application. For instructions regarding the various setting
options, refer to Chapter 9 or the online help for the BPSConfig program.
The setting is usually accomplished by using the program BPSConfig, see "Installing the
"BPSConfig" software" on page 37.
The various parameter sets are explained briefly in the following Chapter 7.3.1, to understand what is happening during parameter setting.
The setting of the parameters then takes place in the "service" operating mode, which is
described in Chapter 7.3.2.
Leuze electronic BPS 37 33
TNT 35/7-24V
Commissioning
7.3.1 Parameter sets
In the BPS 37 three different parameter sets are administered:
• Parameter set with the factory settings in the ROM
• Current parameter set in EEPROM
• Working copy of the current parameter set in the RAM
Before a parameter set is loaded into the memory of the BPS 37 processor, the validity of
the parameter set is verified using check sums.
Factory default parameter set
This parameter set contains the factory-set default settings for all parameters of the BPS 37.
It is permanently stored in the ROM of the BPS 37. The parameter set with the default
settings is loaded into the memory of the BPS 37,
• the first time the device is commissioned after delivery
• following the command "Factory Default" in the configuration program
• if the check sums of the current parameter set are invalid.
Current parameter set
In this parameter set, the current settings for all device parameters are stored. When the
BPS 37 is in operation, the parameter set is stored in the EEPROM of the BPS 37. The
current set can be stored:
• by copying a valid parameter set from the host computer
• by means of an off-line setup with the PC setup program BPSConfig
The current parameter set is loaded into the memory of the BPS 37:
• always after connecting the supply voltage
• following a software reset
The current parameter set is overwritten by the parameter set with the factory settings:
• by a parameter reset, see "Online commands" on page 33
7.3.2 Service operating mode
Setting the required parameters is carried out easiest in the 'Service' operating mode. The
Service operating mode makes the following defined operating parameters available on a
separately wired RS 232 interface, independent from the BPS's configuration for standard
operation:
• transmission rate: 9600 baud
• no parity
• 8 data bits
• 1 stop bit
• prefix: STX
• postfix: CR, LF

Service
Activate service interface
The service interface is activated via a bridge between the pins 7 and 15 on the 15-pin
sub-D connector. If the BPS 37 is operated with a connection unit, the service interface is
activated through a switch in the connection unit.
Connect
You can connect a PC or terminal to the BPS 37 via the serial interface and configure the
BPS 37 through this connection. For this, you need a crossed RS 232 interconnection cable
(null modem cable) that provides the connections RxD, TxD and GND. A hardware handshake via RTS, CTS is not supported at the service interface.
If the BPS is connected to a connection unit, you can use the 9-pin SubD service connector
in the connection unit. For the respective pin assignments, please refer to the data sheet of
the connection unit.
