Read this manual before installingand operating the Micropulse Trans-ducer.

1.1 Proper application

The BTL5 Micropulse transducer isintended to be installed in a ma-chine or system. Together with acontroller (PLC) it comprises a posi-tion measuring system and mayonly be used for this purpose.

Unauthorized modifications andnon-permitted usage will result inthe loss of warranty and liabilityclaims.

1.2 Qualified personnel

This guide is intended for special-ized personnel who will perform theinstallation and setup of the system.

1.3 Use and inspection

The relevant safety regulations mustbe followed when using the trans-ducer system. In particular, stepsmust be taken to ensure that should

2.1 Characteristics

Micropulse transducers feature:– High resolution and repeatability– Immunity to shock, vibration,

contamination and electrical noise– Automatic signal regulation– Switchpoints freely

programmable– Simple programming– Removable calibration device– Pressure rated to 600 bar– IP 67 per IEC 60529

2.2 Functional operation

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 itsposition constantly updated.

The magnet defines the measuredposition on the waveguide. An inter-nally generated INIT pulse interacts

with 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 the wave-guide creates an electrical signal inthe coil surrounding the waveguide.The propagation time of the wave isused to derive the position. Thisprocess takes place with measuringhigh precision and repeatabilitywithin the stroke range defined asnominal stroke 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/con-troller and the power supply is via acable, which is connected using afemale connector.

2 Function and Characteristics

Dimensions for installing the Micro-pulse transducer: ➥➥➥➥➥ Fig. 3-2Dimensions for installing the mag-net: ➥➥➥➥➥ Fig. 3-4.

2.3 Available stroke lengthsand magnets

To ensure flexible application, nomi-nal transducer stroke lengths offrom 25 to 4000 mm and varioustypes of magnets are available.

The magnets need to be orderedseparately.

3.1 Mounting

When possible, use non-magnetiz-able material for attaching the trans-ducer and magnet ring. ➥➥➥➥➥ Fig. 3-1.

When attaching the transducer tomagnetizable materials, appro-priate measures must be taken toprotect against magnetic disturb-ances ➥➥➥➥➥ Fig. 3-1. Note therecommended distance of thetransducer and cylinder fromstrong, external magnetic fields.

3.2 Transducer, Installation

The smallest permissible distancebetween magnet ring and rodmounting surface is shown inFig. 3-2.

The transducer has either aM18×1.5 thread or a 3/4"-16UNFthread for mounting. The sealing iscarried out with the O-ring suppliedat the flange facing.

Important Installation Notes:

The contact surface of the trans-ducer must be completely con-tacted by the mounting surface.The O-ring supplied must make aperfect pressure seal, i.e. the bevelfor the O-ring must be configuredexactly as shown in Fig. 3-3.

To achieve secure mounting, usethe proper nut for the mountingthread. When tightening the nut, do

from wear. The bore diameter inthe piston and cylinder rod shouldbe at least 13 mm.

When attaching the transducer tomagnetizable materials, appro-priate measures must be taken toprotect against magnetic disturb-ances, ➥➥➥➥➥ Fig. 3-1.

Note the recommended distanceof the transducer and cylinder fromstrong, external magnetic fields.

3.3 Magnets, installation

A magnet is required for each trans-ducer. This must be ordered sepa-rately. ➥➥➥➥➥ Fig. 3-4.

For mounting the magnet we rec-ommend to use non-magnetizablematerial. ➥➥➥➥➥ Fig. 3-1.

BTL-P-1013-4S

BTL-P-1012-4R

Note the following when mak-ing electrical 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 controlmust be connected usingshielded cable.

Shielding: Copper filamentbraided, 85% coverage.

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.

Cable length max. 20 m; Ø 6 to8 mm. Longer lengths may be usedif construction, shielding and routingare such that external noise fieldswill have no effect on signal integrity.

The shield must be tied to theconnector housing in the BKSconnector (➥➥➥➥➥ Fig. 4-3); see in-structions accompanying theconnector.

The cable shield must be groundedon the control side, i.e., connectedto the protection ground.

Pin assignments can be found in➥➥➥➥➥ Table 4-1. Connections on thecontroller side may vary accord-ing to the controller and configu-ration used.

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 connec-tions 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.

Please note:

The calibration device is to be at-tached to the connection end ofthe transducer as shown in➥➥➥➥➥ Fig. 6-1. Connect the trans-ducer to the controller. All set-tings are done with a magnetwithin the stroke area.

Any desired position of the magnetcan be defined as a switchingpoint.

Therefore make sure that no haz-ards could result from thesesituations.

5.3 Check switching points

After replacing or repairing atransducer, you must reprogram theoutputs.

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.

In programming mode the outputsare used as a reply or stateindicator. Therefore they may not beused for controlling the machine.Once the programming procedure isconcluded, the calibration devicecan be removed to prevent acciden-tal changes and to store in a safeplace for the next use.The buttons are automatically dis-abled after approximately 2 minutesof non-use.

Instead of the calibration device, theprogramming inputs La and Lb maybe used for programming:La = Button 1; Lb = Button 2Programming input grounded GND=̂ Button pressed.Default: No output programmed.The last programmed values re-main stored, regardless of whetherthe programming mode is endedmanually by pressing the buttonsor automatically after 2 minutes.

Each output can be programmedwith positive or negative logic andas a cam (= 2 switchpoints) or as asimple switchpoint.

The magnet must be located in thedesired position, which is thendefined as a switchpoint (SP).
