ROTALIGN® PROThe ultimate in laser shaft alignment

As maintenance technicians’ jobresponsibilities grow more varied,so does the need for an alignmentsystem to do more. Most systemscan deal with horizontal and verti-cal machinery and measure softfoot. Some can even measure mis-alignment uncoupled – but thenew ROTALIGN® PRO does muchmore. It lets you align machinetrains of up to six machines, calcu-

lating which machine feet to movein order to minimize correction ef-fort. It not only measures soft footbut also analyzes it and suggestscorrective action. It can even com-pute thermal growth for you.But ROTALIGN® PRO does not stopat the alignment of rotating ma-chines: it also features an optionalprogram for accurate single-passstraightness measurement.

alignment pays for itself!

ROTALIGN® PROdoes it all!

Reduces bearing and seal damage

Minimizes energy loss

Cuts production downtime

ROTALIGN® PRO makes quick, ac-curate shaft alignment a simpleaffair for new users, yet offersexperts the functions they need inorder to master special challengessuch as machine trains and cardanshafts, flange-mounted machinesand nonrotatable shafts – all just afew keystrokes away.

3-key alignment:Quicker, easier, more flexible

Measures all by itself!Simply adjust the laser beam, thenrotate the shafts to begin measure-ment: in less than a quarter-turn,ROTALIGN® PRO automatically reg-isters enough points to determinealignment accurately.

Quick and easy setupThe job setup screen gets you upand running quickly with a clear,yet detailed diagram of the ma-chines to be aligned. The samescreen also lets you add machinesto new or existing trains, specifycoupling types and dimensions,RPM, amount of thermal growthand much more!

Flange-mounted machines:a breeze to align!Precise alignment of verticalmachines and horizontalflange-mounted machines wasnever this easy! ROTALIGN®

PRO shows shimming correc-tions for each flange bolt andlets you monitor lateral posi-tioning 'live' on screen as well.

No machinetoo ‘exotic’

3Alignment resultsin theirmost usable form

The whole pictureat a glanceROTALIGN® PRO shows you thecomplete alignment condition ina single clear screen: couplingmisalignment, machine foot cor-rections, even tolerance com-pliance indicated by 'happy faces'for horizontal and vertical planes.

Ultimatealignment convenienceMachine templatessave setup time!Why spend time entering everymachine detail by hand beforeeach alignment job? Machinetemplates offer predefinedconfigurations including ma-chine types/names, identifica-tion tags, dimensions, toler-ances, targets etc.

Truly traceable results,every step of the way!Document every step of theentire job with the 'Job Record'feature of ROTALIGN® PRO,complete with comments (e.g.‘as found,’ ‘as left’ etc.) forISO-compliant traceability.

Choose your machine!Select your specific machinetype and its detailed depictionfrom a built-in selection. Thismakes for especially conve-nient handling of multi-ele-ment machine trains and alsoenhances your alignment re-ports.

The right bracketsfor all your machines

Shafts can't be rotated? No prob-lem with ROTALIGN® PRO! Simplyplace the ALI 2.230 magnetic slid-ing bracket onto the couplingflange or shaft end and slide itaround the circumference to takemeasurements in seconds. Suitablefor shaft/coupling diameters fromapprox. 80 mm (3 1/8") on up.

Instant mounting on any ferromag-netic surface: just place the time-saving ALI 2.112 compact magnet-ic brackets onto coupling flangesor shaft faces and you're all set!Powerful magnets hold sensors rig-idly in place for measurement, yetallow extremely easy, flexible ad-justment.

Quite possibly the only bracketyou'll ever need: the standardROTALIGN® PRO compact chain-type bracket ALI 2.891set uses in-terchangeable parts to fit ontoshafts and solid couplings rangingfrom 15 mm to 500 mm (5/8" to20") in diameter in a matter ofseconds!

Alignment advantagesthrough technology

PRO as in ‘protection’ROTALIGN® PRO means industrial-strength alignment: its shockproof,IP67 rubberized components re-main unaffected by water spray,grime and solvents, while the rug-ged flat keyboard gives a positiveresponse even through heavy workgloves. The lockable flight case(shown here in optional matte alu-minum) keeps all standard systemcomponents and frequently-usedaccessories in perfect order.

Beforelinearization

Afterlinearization

High-precision detectorgives unparalleled accuracyEven the best commercially-avail-able position detectors are nomatch for those linearized by theunique PRÜFTECHNIK AG process:each individual detector undergoesa complex mathematical optimiza-tion procedure to give exceptionalaccuracy over a large measurementarea. This enables you to performalignment reliably at separations of10 m (33 ft.) and beyond!

Ultimate flexibility: Measurein a quarter-turn or less!Two built-in electronic inclinome-ters continuously keep track of theshaft rotation angle for eachmeasurement of laser beam posi-tion. This ensures that alignmentcorrections are calculated preciselyfor vertical and horizontal direc-tions, and thanks to the patentedmeasurement techniques, you caneven measure

• in one continuous sweep!• in less than 1/4 turn!• in either direction!• from any starting position!

The timesaving PC partner:ROTALIGN® PRO Commander

ROTALIGN® PRO Commander soft-ware saves alignment time at thejob site by giving you completecontrol with the point-and-clickease of Windows™ 95 or NT! Dis-play and store alignment results,customize the ROTALIGN® PROcomputer and specify all aspects ofthe machines to be measured. De-fine machine templates, even forentire trains of up to six machinesin one file. Select among alignmenttolerance tables or modify them tosuit your particular circumstances.Machine definitions and measure-ment results are logically organizedby plant, area and machine train oraggregate.

PC support: before, during & after

Built-in soft foot expertise!The new Soft Foot Wizard (patentpending) helps you resolve difficultmachine frame distortion problemson the spot. One soft foot, twosoft feet, rough adjustment of se-vere soft foot, or induced soft footfrom piping strain or severe mis-alignment: the Soft Foot Wizardrecognizes such situations andgives you expert recommendationson how to handle them.

Align cardan shaftsCardan shafts save space by run-ning at an angle. But misalignmentcan pose a serious threat (especial-ly to electronically-controlled syn-chronous and asynchronous ACdrive motors) due to rapid RPMfluctuation of the drive shaft.ROTALIGN® PRO masters cardanshafts with ease thanks to a newspecial function and optionalALI 2.893SET large-offset brackets.

Machine train alignment!ROTALIGN® PRO handles trains ofup to 6 machines (5 couplings),complete with specific tolerances,targets, names and icons for eachmachine. Machine trains can havehorizontal or vertical shafts, with orwithout flange-mounted (C-face)machines!

Alignment power for any situation

Thermal growthcomputation!No specs available for compensa-tion of thermal effects? LetROTALIGN® PRO compute thermalgrowth based on temperaturechange, machine geometry andmaterial coefficient of thermal ex-pansion - even when machinestructural components are made ofdifferent materials!

Straightness measurementwith ease!Now measure straightness (verticaland horizontal) of ways, beds andother applications, far more quicklyand accurately than with conven-tional taut wires, theodolites oreven other laser methods. Optionalstraightness module ALI 3.630SETincludes adjustable brackets that fita wide range of workpieces.

Straightforward resultsROTALIGN® PRO shows you verticaland horizontal offsets at a glance,based upon optimized correctionvalues or your choice of stationarypoints – and guides you throughcorrections 'live' on screen as wellin both horizontal and vertical di-rections at the same time.

Advanced design featuresmean fast, accurate resultsROTALIGN® PRO measures align-ment by tracking to the nearest1/1000 mm laser beam displace-ment over the surface of a positiondetector as the shafts are turned.The more accurately this measure-ment is made, the more reliablethe alignment corrections will be.And accuracy is enhanced by fea-tures like dual inclinometers and aquadruple-axis position detectorwith ultra-precise linearization.

Cordless measurement!No more cable to constantly dis-connect and reconnect when largeshafts require use of turning gearsfor measurement rotation or in“hot” (radiation) areas. The op-tional infrared data transmissionlink ALI 4.609SET is invaluable forpassing alignment readings fromthe measurement receiver to theROTALIGN® PRO computer, reliablyand with no cable connections.
