2.2 Function

The transducer contains a tubularwaveguide enclosed by an extrudedaluminum housing. A magnet at-tached to the moving member ofthe machine is moved across thetop of the housing and its positionconstantly updated.

The magnet defines the measuredposition on the waveguide. An inter-nally generated INIT pulse interactswith the magnetic field of the mag-net to generate a magnetostrictivetorsional wave in the waveguidewhich propagates at ultrasonicspeed.

The torsional wave arriving at theend of the waveguide is absorbedin the damping zone. The wavearriving at the beginning of thewaveguide creates an electricalsignal in the coil surrounding thewaveguide. The propagation time ofthe wave is used to determine theposition to a resolution of 5 µm.This takes place with high precisionand repeatability at the selectedresolution within the measuringrange indicated as the nominalstroke length.

3.1 Transducer installation

Ensure that no strong electrical ormagnetic fields are present in theimmediate vicinity of the trans-ducer.

Any orientation is permitted. Thesupplied mounting brackets andcylinder head screws allow the

3 Installation

transducer to be mounted on a flatmachine surface. A sufficient quan-tity of mounting brackets is sup-plied. These should be evenlyspaced ( Figs. 3-1 to 3-5). Therecommended spacing for longtransducers and extreme conditions(e.g. strong shock or vibration):A = 80 mm; spacing between theindividual brackets B = 250 mm.

The supplied isolation bushings areused to electrically insulate thetransducer from the machine( Fig. 3-5 and chapter 5.6 Noiseelimination).

The Micropulse transducer in profilehousing is suitable both for floating,i.e. non-contacting magnets( Figs. 3-1 and 3-2, also page 6)and for captive magnets ( Figs.3-3 and 3-4, also page 7).

4 Wiring

Note the following when makingelectrical connections:

System and control cabi-net must be at the sameground potential.

To ensure the electromagneticcompatibility (EMC) which Balluffwarrants with the CE Mark, thefollowing instructions must bestrictly followed.

BTL transducer and the proces-sor/control must be connectedusing shielded cable.

Shielding: Copper filamentbraided, 80% coverage.

The shield must be tied to theconnector housing in the BKSconnector ( Fig. 4-4 or Figs.4-8, 4-9, and 4-11); see instruc-tions accompanying the connec-tor.

The cable shield must begrounded on the control side, i.e.,connected to the protectionground.

The Profibus bus line should berouted according to thePROFIBUS Technical Guidelines,Assembly Guideline PROFIBUS-DP/FMS.

Pin assignments can be found in Table 4-2 or in Tables 4-3and 4-4.

When routing the cable between thetransducer, controller and powersupply, avoid proximity to high volt-age lines to prevent noise coupling.

Especially critical is inductive noisecaused by AC harmonics (e.g. fromphase-control devices), againstwhich the cable shield provides onlylimited protection.

The signal is sent to the controllerover the PROFIBUS-DP interface.

Max. cable length of the intire field-bus: 1200 m.

The transmission speed is a func-tion of cable length. EN 50170 isthe reference for the values given in Table 4-1.

Cable length Baud rate [kbps]< 100 m 12,000< 200 m 1,500< 400 m 900

< 1000 m 187.5< 1200 m 93.7 / 19.2 / 9.6

Table 4-1:Baud rate vs. cable length

The bus must be terminated at bothends as per EN 50170. Fig. 4-1or Fig. 4-6.

The BTL5-T provides the optionof assigning the station addressusing DIP switches. For additionalinformation see Section 7 Con-figuration.

5.1 Check connections

Although the connections are polar-ity reversal protected, componentscan be damaged by improper con-nections and overvoltage. Beforeyou apply power, check the con-nections carefully.

5.2 Turning on the system

Note that the system may executeuncontrolled movements when firstturned on or when the transducer ispart of a closed-loop system whoseparameters have not yet been set.Therefore make sure that no haz-ards could result from these situa-tions.

5.3 Check output values

After replacing or repairing a trans-ducer, it is advisable to verify thevalues for the start and end positionof the magnet in manual mode. Ifvalues other* than those presentbefore the replacement or repair arefound, a correction should bemade.* Transducers are subject to modifi-

cation or manufacturing tolerances.

5.4 Check functionality

The functionality of the transducersystem and all its associated com-ponents should be regularlychecked and recorded.

5.5 Fault conditions

When there is evidence that thetransducer system is not operatingproperly, it should be taken out ofservice and guarded against unau-thorized use.

5.6 Noise elimination

Any difference in potential - currentflow - through the cable shieldshould be avoided. Therefore:– Use the isolation bushings, and– Make sure the control cabinet

and the system in which theBTL5 is contained are at thesame ground potential.

7 Configuration

Fig. 7-2: View A, DIP switches S1and S2 for setting station address

Fig. 7-1: Location of DIP switchesS1 and S2

7.1 Default settings

The transducer is supplied with thefollowing default settings:– Station address 126– Resolution:

Position 5 µmVelocity 0.1 mm/s

– Maximum working/useful area

7.2 Presets

The service Set_Slave_Address canbe used to configure the stationaddress. For this service you need aDP Master Class 2. The GSD fileBTL504B2.GSD (transducer system)is used for configuration. The GSDfile provides all the information re-quired for settings. For configuring,the Siemens COM PROFIBUS canbe used for example.

For use in standard PROFIBUSsystems the station address is setbefore startup using the DIPswitches S1.1...S2.3 which are builtinto the BTL ( Figs. 7-1 and 7-2).

When opening the BTL housingmake sure no parts get into thedevice.

When closing up the cover ensurethe gasket is sufficientlycompressed. Tighteningtorque: 0.8 Nm

Values from 0 - 125 can be used forthe station address. In a networkeach address can be used onlyoince! For value 126 the address126 or the last address set usingthe Set_Slave_Address service isused. A value of 127 resets the BTLto its default condition. Since 127does not represent a valid address,bus operation is then not allowed.

All address settings only becomeeffective after a power reset.Changes which are made whilepower is on do not therefore havean immediate effect.

To ensure a reliable rest signal levelthe bus must be appropriately ter-minated on both ends as shown inFig. 4-1 and 4-6. For IP 67 with theBTL5...S 103 the bus terminationresistor suggested in Fig. 4-12 mustbe used. Stub lines should beavoided whenever possible.

7.3 Configuration withCOM PROFIBUS

To configure the BTL5-T using COMPROFIBUS configuration software,you must be sure to use Version 5or higher of COM PROFIBUS.

7.3.1 Importing BTL5-T

In order to use the BTL5-T in thesoftware, the GSD and an associ-ated bitmap file must be importedinto the corresponding directoriesof COM PROFIBUS.

The GSD file BTL504B2.GSD iscopied to the subdirectory \GSD . Fig. 7-3

The station address configured onthe BTL is set under the parameter'PROFIBUS-Address'. Values from0-125 are allowed. For better identi-fication a name can be entered forthe BTL in the 'Station name' field.

Fig. 7-6: 'Slave Properties' menu with BTL5-T

Fig. 7-7: Configuration menu (no parameter set)

If there is more than one Master inthe network the selection box'Param. assign. master' can beused to select a Master which setsth eparameters for the BTL uponsystem start.

The [ Configuration ] button is usedto open the dialog for BTL param-eterizing. Fig. 7-7

Since the BTL5-T is a modular de-vice there is no active parameterrecord shown in the illustration. For

this reason the first step must be toselect an appropriate parametermodule. Activate the selection list

by clicking on the [ Module ] button. Fig. 7-8


15english


Double clicking on the desired mod-ule adds it to the configurationtable. Since the BTL is a single-module device, only one modulecan be selected at a time. If a mod-ule was selected previously, theexisting module must be deletedbefore making another selection. Fig. 7-9

7.5 General configurationnotes

If you have problems during startupor configuration of the BTL5-T,check the following points:– The device address used in the

configuration system must agreewith the address set on the BTL.

– The module must be selected toconform with the BTL used. If indoubt, check the BTL part num-ber.

– Depending on the parameterassignment you have performed,both the number and the formatof the output values may vary.


– If the CPU-315-2-DP is used asthe Master, consistend data canbe represented in theprocessmap only using a maximum of 2words (1x position). To read con-sistent data >4 bytes the SFC 14must be used.

– Exceeding the programmedworking range limits causes theBTL to issue a diagnostic report(External User Diagnostic). Thisdiagnostic report can be readusing SFC 13.

– In standard configuration, assoon as an External User Diag-nostic is issued the CPU-315-2-DP switches over to Stop state

(controller program stops run-ning). If this response is not de-sired, OB82, OB86 and OB1212should be implemented in thecontroller. Error response can beencoded in these OBs specifi-cally for each PROFIBUS station.For this you must select the CPUin the hardware configurator andopen the menu 'Extras' 'Re-port system error' . Fig. 7-18Reporting of system errors to theOBs is activated by using thecheckbox 'Create Error OBs'.The content of the Error OBsmust then be appropriatelycoded in the control program.
