2.1 Characteristics– High data reliability: output data

are checked in the µC for validityand plausibility.

– Up to 4 positions can be pro-cessed

– Definable working strokes– Absolute output signal– High resolution, repeatability and

linearity– Insensitive to shock, vibration,

contamination and noise– Max. fieldbus length 1200 m– Configuration using Step7, COM-

PROFIBUS, WinDP, or otherconfiguration softwarer

– Protected to IP 67 per IEC 529– Pressure rated to 600 bar.– DIP switches for address setting– DIP switches for bus termination

2.2 Function

The transducer contains a tubularwaveguide enclosed by an outerstainless steel rod. A magnet at-tached to the moving member ofthe machine or to the cylinder pis-ton is moved over the rod and its

position constantly 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 absorbed inthe damping zone. The wave arriv-ing 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.

At the rod end is a damping zone,within which no reliable signal isavailable, but which may be enteredby the magnet.

The electrical connection betweenthe transducer, the processor cardor controller, and the power supply

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 ➥➥➥➥➥ Figs. 4-3, 4-4, and4-6; see instructions accompany-ing the connector.

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➥➥➥➥➥ Tables 4-2 and 4-3.

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 is thereference 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. 4-1

The BTL5-T provides the optionof assigning the station addressand of terminating the bus inter-nally using DIP switches. Foradditional information see➥➥➥➥➥ Section 7 Configuration.

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 be made.* 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.

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 PROFIBUS sys-tems the station address is set be-fore startup using the DIP switchesS1 which are built into the BTL➥➥➥➥➥ Figs. 7-1 and 7-2 as well asTable 7-1.

When opening the BTLhousing make sure noparts get into the device.

When closing up the cover en-sure the gasket is sufficientlycompressed. Tightening torque:1,5 Nm

Fig. 7-3: GSD files in the subdirectory \GSD

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.

TTo ensure a reliable rest signallevel the bus must be appropriately

terminated on both ends as shownin Fig. 4-1. The BTL5-T allows thebus to be terminated internally. Todo this set DIP switches S1.9 andS1.10 to ON, ➥➥➥➥➥ Fig. 7-2. For IP 67the bus termination resistor sug-gested in Fig. 4-7 must be used.Then the internal bus terminationshould not be activated (S1.9 andS1.10 OFF)!. 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 directories ofCOM PROFIBUS.

7.5 General configuration notes

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 as


the 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.
