1 IntroductionTopics covered in this chapter: Alignment overview Laser Align Application overview Laser Align Application main menu

1.1 Alignment overviewTo achieve ideal machine alignment, the shaft centerline of one machine element (such asa motor) must coincide with the centerline extension of another machine shaft (such as apump) during operation. In more complex applications, three or more elements may bealigned in a train.Misalignment can occur both horizontally and vertically. The two components ofmisalignment are angular and offset. Most misaligned machines have a combination ofoffset and angular misalignment. See the following figure for the different types ofmisalignment. Correcting misalignment involves aligning the shafts vertically andhorizontally.

Alignment conditionsFigure 1-1:

Poor shaft alignment can cause problems such as bearing failure, shaft deflection fatigue,seal leakage and failure, coupling failure, overheating, excessive energy consumption,excessive machine vibrations, among others. Whereas proper machine alignment resultsin less downtime, increased bearing life, lower energy costs, extended coupling life, andlower maintenance costs.

Introduction

Quick Start Guide - DRAFT 1

Properly aligning machine shafts involves at least the following steps:1. Preparation and setupthis includes inspecting for soft foot, base integrity, pipe

strain, and knowing the acceptable tolerance levels. See Section A.6.2. Misalignment measurementmeasuring the amount and direction of

misalignment.3. Calculating corrective moves.4. Moving the equipment within preset tolerances.5. Storage and documentation of data for future alignment jobs.

1.2 Laser Align Application overviewThe CSI 2140 Laser Align Application lets you perform horizontal, vertical, and straightnessalignment jobs. Alignment is done with the help of the sensALIGN laser and sensor fromPRFTECHNIK.You can create alignment jobs for a machine and transfer it to AMS Machinery Manager forstorage and analysis.For the purpose of this manual, only horizontal alignment is discussed.

2 Laser and sensor setupTopics covered in this chapter: Get to know the laser and sensor Mount the brackets Mount the laser and sensor Enable or disable the Bluetooth radio in the analyzer Pair the sensor Laser beam adjustment LEDs Charge the laser and sensor

2.1 Get to know the laser and sensorThe sensALIGN laser and sensor from PRFTECHNIK communicate via Bluetooth withEmerson's CSI 2140 Machinery Health Analyzer.

sensALIGN laser and sensorFigure 2-1:

Laser and sensor setup


The laser and sensor have a similar appearance and are differentiated by the color of their sliding dust capsyellow for the laser and red for the sensor. Both are powered on by pressing and holding the on/off switch briefly. The beam active LED then lights red.The sensALIGN laser (P/N 4910)Information regarding the battery status, the rotational angle, the temperature and theserial number of the laser are transmitted through the laser beam into the sensor.The beam is adjusted during set-up by changing its vertical and horizontal angles using theposition thumbwheels, so that the beam strikes the sensALIGN sensor lens perpendicularto the lens surface.The laser is water and dust resistant (IP 65). The internal optics and electronics areinternally sealed, preventing possible contamination.The sensALIGN sensor (P/N 4900)The sensALIGN sensor contains two position detectors that measure the exact position andinclination of the laser beam as the shafts are rotated.Bluetooth radio is integrated into the sensor for wireless transmission of measurementdata to the CSI 2140. The sensor also transmits sensALIGN laser data to the computer. Thesensor technology is used to determine shaft rotational angle and machine vibration.Terminology

Term MeaningLaser Refers to the sensALIGN laser (P/N 4910)Sensor Refers to the sensALIGN sensor (P/N 4900)Laser fixtures Refers to both the sensALIGN laser and sensor



2.1.1 Laser safety

Do not look directly into the laser beam at any time. Do not insert any optical devices into the beam path.

NoteThe red LED on the front of the laser illuminates whenever the laser beam is emitted.

2.2 Mount the bracketsMount the brackets on either side of the coupling on either the shafts or on the solidcoupling hubs, and both at the same rotational position.PrerequisitesNote the following to obtain the highest possible measurement accuracy and to avoiddamage to equipment: Ensure that the brackets fit solidly onto their mounting surfaces. Do not use self-constructed mounting brackets, or modify the original bracket

configuration supplied by PRFTECHNIK (for example, do not use support postslonger than those supplied with the bracket).

Procedure1. Choose the shortest support posts that will still allow the laser beam to pass over or

through the coupling. Insert the support posts into the bracket.2. Fasten the support posts in place by tightening the hex screws on the sides of the

bracket frame.



3. Place the bracket on the shaft or coupling, wrap the chain around the shaft and feedit through the other side of the bracket: if the shaft is smaller than the width of thebracket frame, insert the chain from the inside of the bracket as shown in Figure 2-2;if the shaft is larger than the bracket width, insert the chain into the frame from theoutside.

4. Catch the chain loosely on the anchor peg.5. Turn the bracket thumbscrew to tighten the assembly onto the shaft.6. Clip the loose end of the chain back onto itself.

The bracket should now be tight upon the shaft. Do not push or pull on the bracketto check, this could loosen its mounting.To remove the brackets, loosen the thumbscrew, then remove the chain from itsanchor peg.

Mount the bracketsFigure 2-2:

NoteThe compact chain-type brackets cover most situations, but in cramped or special cases, other typesof brackets may be required.

2.3 Mount the laser and sensorProcedure1. Before mounting both laser and sensor, make sure that the yellow clamping levers

are in the open position by pointing them to the front of the laser fixtures. Thisenables the laser fixtures to slide onto the support posts.



Clamping leversFigure 2-3:

2. Fix both the laser and sensor onto the respective support posts by locking the yellowclamping levers. Lock the levers by pushing them backwards until they rest on thestoppers. Ensure that the laser beam can pass over or through the coupling and isnot blocked.

NoteBoth the laser and sensor should be at the same height, as low as possible, yet just highenough for the beam to clear the coupling flange. They should also visually appear to berotationally aligned to each other.

Horizontal alignmentFigure 2-4:



3. Make final adjustments, loosening the brackets slightly if necessary, then rotatingthem and re-tightening.

2.4 Enable or disable the Bluetooth radio in theanalyzerIf your analyzer is configured for Bluetooth, you can enable or disable the internal radio.After you enable the analyzer's Bluetooth radio, the analyzer searches for nearby Bluetoothdevices that you can pair. The radio remains on until you disable it.Procedure1. Press Home > F5 Comm Setup > F7 Bluetooth Setup.2. Press F2 Bluetooth to enable or disable the Bluetooth radio.

When the radio is enabled, the Bluetooth LED on the top of the analyzer turns onand the icon appears in the upper corner of the screen.

2.5 Pair the sensorTo establish communication with the laser, sensor, and the analyzer, you must first pairthe sensor.Prerequisites Ensure that the laser fixtures are close to the analyzer (within 30 feet), turn them on,

and make sure that they are in discoverable mode. Ensure the Bluetooth radio in your analyzer is enabled. See Section 2.4.Procedure1. Press Home > F5 Comm Setup > F7 Bluetooth Setup.2. If more than one device is listed, use the up or down arrow keys to select the sensor.

Bluetooth radio is integrated into the sensor.3. (Optional) Press F8 Device Info to view information about the sensor, including

device alias (if you renamed the device), device name, supported protocols, statusand device address.

4. Press F7 Pair to pair the sensor.

2.6 Laser beam adjustment LEDsThe four beam adjustment LEDs provide additional help when adjusting the laser beamposition on the sensor position detectors.



The LEDs indicate the angle and position at which the laser beam enters the sensor. TheLEDs blink either red or green depending on the angle at which the laser beam strikes thesensor. Green indicates a small angle while red indicates a large angle that must becorrected before beginning measurement.

Laser beam adjustment LEDsFigure 2-5:

One or more LEDs blink red every second

Laser beam entering sensor with little ornegligible angular deviation but with an offset

All four LEDs blink green twice every second

Laser beam entering sensor with neitherappreciable angular deviation nor offset

All four LEDs blink green every second

2.7 Charge the laser and sensorBoth the laser and sensor are powered using the sensALIGN rechargeable battery (ALI4.960 a 3.7 V 1.6 Ah Lithium Polymer).Procedure1. In the laser or sensor, remove the cover from charger/adapter socket.2. Charge the battery in the laser or sensor using the sensALIGN charger/adapter (ALI

4.651-I).

4. Enter thermal growth values if thermal growth is enabled and press Enter. See Section A.9 for information on thermal growth and Section 3.1.9 for moreinformation on enabling the thermal growth option.

NoteAll machine dimensions must be entered before advancing to the thermal growth screens.



3.3 Acquire alignment data (horizontal alignment)After entering machine dimensions, the Laser Align Application automatically advancesyou to the next step, which is to acquire alignment data by sweeping the laser and sensor(Sweep Heads). After completing this step, the Sweep Heads function on the Laser AlignApplication main menu is marked with an X.

TipFor accuracy and repeatability, take note of the following guidelines when acquiring alignment data: Acquire all readings using the same direction of rotation. Rotate the laser fixtures in the same direction as the machines rotate when running. Aim for a smooth, uniform acceleration and deceleration during the rotation of the laser

fixtures to get accurate, reliable, and repeatable data.

PrerequisitesMake sure the laser and sensor are mounted on the machine, are turned on, and have beenpaired with the analyzer.Procedure1. Enter machine dimensions and press Enter.2. Acquire alignment data. The way to do this varies depending on the alignment

method you have previously chosen. See Section A.8 for more information on thealignment methods.

b. Rotate the laser fixtures while stopping at points to take a reading. Press AcceptReadings after stopping at each point. A minimum of 3 data points over a 45sweep arc is required. Emerson, however, recommends 8 data points (samples)over a sweep arc of at least 90.

c. After taking the desired readings, press Enter.Auto 4 Point

Auto 4 PointFigure 3-6:

a. Position the laser and sensor at a starting angle (ideally at the first cardinalposition, that is 0). Make sure the laser and sensor and within 2 of each other.The position of the laser fixtures is marked on the screen with a black line insidethe circle below the machine.The laser and sensor angles should be within 2 of each other and within 3 of theactive cardinal position (0, 90, 180, and 270). When this happens, the boxdisplayed below the machine is green. If the laser and sensor angles are notwithin 2 of each other and within 3 of the active cardinal position, the boxbackground is white.



b. Rotate the laser fixtures a full revolution. The reading at each cardinal position(0, 90, 180, and 270) is automatically averaged and stored.The analyzer produces an audible tone whenever a reading is stored. This isavailable when the Status Beeper on the General Setup is set to on.

NoteWhen using Auto 4 Point, an alternative option to increasing the number of samples (orincreasing the data averaging beyond 25 samples per reading) would be to stop the laserfixtures at each cardinal position and allow the program to continuously average the data.

A.6 Pre-job preparation and setup1. Before starting any alignment job, review the history of alignments performed on

the machines.Were there any special problems found during the previous alignment; if so, whatwere they (soft foot, piping strain, coupling problems, etc.)? How well was themachine aligned and who performed the alignment? Answering these questionsalong with having a predefined job setup reduces the pre-job preparation time anddecreases the total time to perform the alignment.

2. Before proceeding with alignment measurements, ensure that your machines aremounted on the base, or foundation, with no soft foot condition present.Uneven height of the base surface, dirt or corrosion under the feet, or otherirregularities can all cause the machine to be supported unevenly; a conditionknown as soft foot. Soft foot problems can place stress on the machine when theanchor bolts are tightened. In addition to preventing proper machine alignment,extreme soft foot conditions can actually cause damage to the machine (warped orcracked feet, etc.).Two major reasons for correcting soft foot are (1) to avoid continuous realignmentsdue to differing machine foot positions and (2) to remove the stress and enable themachines to operate at their best. Therefore, all machines should be checked forsoft foot, not just the machine being moved.

References


3. Use proper foundation.On new installations, allow foundation concrete to cure sufficiently before installingyour machines. Normally, you should not mount machines directly on thefoundation. Baseplates usually provide more stability. Also, to make futurealignments easier, a set of high quality (i.e. stainless steel) pre-cut shims should beplaced beneath each foot. They should be at least 1/8 inch (3 mm) thick.

4. Properly select and install coupling.The alignment system is not affected by axial float, and the effects from torsionalplay (backlash) in the coupling are minimal. However, you should ensure that thecoupling is properly installed and not in a poor condition that it adversely affects thealignment process. Also, Emerson recommends (while alignment is beingperformed) that you eliminate torsional play by rotating the driving machine in thesame direction that it normally operates. If necessary, put a drag on the driven endto prevent gravity overswing.

5. Minimize pipe strain.Excessive pipe strain can create serious problems and should be corrected beforeattempting machine alignment. Ensure that pipes are fitted correctly and, ifnecessary, obtain flexibility. In some cases, stationary pipes fitted directly to themachine can cause machine movement as they heat up (thermal growth).

6. Make sure the grouting is of suitable material with no voids or cracks.7. Make sure the baseplate is clean, rigid, and properly designed.8. Make sure the machinery element supports have no cracks and are tight.

A.8 Methods for acquiring dataTo cater to data acquisitions for varying applications, circumstances, and preferences,different data collection methods are available for horizontal alignment jobs. The dataacquisition screens vary depending on the alignment method defined for the job.

NoteChanging the alignment method is only available in Advanced job mode and only for horizontalalignment jobs.

Auto SweepThis is the default alignment method.With Auto Sweep, the laser fixtures automatically acquire data using their built-ininclinometers while the shaft is rotated. The arc of rotation can vary from 45 to 360 (onerevolution). This method is especially useful when the 4-point measurement technique isimpractical or when inconsistencies in shaft position exist at points in the rotation.Data readings or values are automatically acquired and stored in the laser fixtures at every2. In a 360 sweep, it is possible to acquire up to 180 data readings.When Auto Sweep is selected as the laser alignment method, you must also select eitherStandard or Averaging as the acquisition mode.The Standard mode is most often used during horizontal alignments. In this mode, oncethe direction of rotation is defined by the laser fixtures, any previous data stored isoverwritten by any new data acquired at the same angular position.The Averaging mode is intended to allow multiple sampling of data in order to reduce thenoise in the data by averaging all of the acquired values. In this mode, once the direction ofrotation is defined by the laser fixtures, any previous data stored is averaged with any newdata acquired at the same angular position if the laser or sensor has been moved at least20 in the reverse direction or a full 360 sweep is performed.

References


Pass ModePass Mode functions similar to Auto Sweep. The laser fixtures automatically acquire datausing their built-in inclinometers as laser and sensor pass by each other. Pass Mode isuseful for performing uncoupled or non-rotational alignments.The arc of rotation can vary from as little as 45 to a full 360 (one revolution). This methodis especially useful when the 4-point measurement technique is impractical or wheninconsistencies in shaft position exist at points in the rotation.Manual SweepWith Manual Sweep, the laser fixtures' built-in inclinometers are used while the shaft isrotated, but data is manually acquired and stored in the Laser Align Application instead ofin the laser fixtures. Manual Sweep functions similar to Auto Sweep except that the laserfixtures, or shafts, are stopped at each position and that data is manually taken. Data fromup to 180 positions may be recorded.The arc of rotation can vary from as little as 45 to a full 360 (one revolution). This methodis especially useful for performing uncoupled or non-rotational alignments or when toomuch background vibration is present.This is the recommended sweep method for sweeps that are less than 75.Auto 4 PointWith Auto 4 Point, data is acquired at the traditional cardinal positions (0, 90, 180, and270). In this method, the laser fixtures' built-in inclinometers are used while the shaft isrotated, but data is automatically acquired and stored in the Laser Align Applicationinstead of in the laser fixtures.The laser fixtures are mounted on a shaft, and the shaft is then rotated so that data can betaken when the laser fixtures are at the 12 oclock (0 or 360), 3 oclock (90), 6 oclock(180), and 9 oclock (270) positions. The readings are continuously averaged wheneverthe laser and sensor are at one of these positions and automatically recorded when theshaft is rotated to the next position. The averaging process reduces variation from jitterdue to background vibration or from slight changes in the angular position of the laserfixtures.When using Auto 4 Point, you must also set the sample rate. The sample rate determinesthe number of data samples that will be collected and averaged together.Manual 4 PointWith Manual 4 Point, the user has complete control over when data is acquired and inwhich of the four measurement positions data is to be acquired. This method is usefulwhen the machinery is not mounted in a true horizontal orientation, so that theinclinometer is not effective or when the clock positions relative to vertical and horizontalbase movements of the machine are nonstandard.Readings are not continuously averaged whenever the laser fixtures are at one of thecardinal positions.When using Manual 4 Point, you must also set the sample rate. The sample ratedetermines the number of data samples that are to be collected and averaged together.

A.9 Thermal growthThermal growth can cause a machine alignment to change significantly as machines arestarted from a cold position and run up to operating speed (hot position). You canenter thermal growth values for both machines.

Notes Entering thermal growth values is only available in Advanced job mode and only for horizontal

alignment jobs. Thermal growth is not available when Quick Spec mode is activated. It is also not supported in

vertical and straightness alignment jobs.

See Section 3.1.9 for more information on enabling the thermal growth option.You can enter the amount of thermal growth at the machine feet or at the machine profilepositions (which are then converted to the corresponding movement at the machine feet).The following are the methods of converting from target thermal growth alignmentnumbers (usually provided by the equipment manufacturer) to estimated machinethermal growth movements at each foot: At Feet At Profile Gap/Offset Face/Rim Reverse DialAt FeetWhen this option is selected, you can enter vertical and horizontal thermal growth valuesat each machine foot. Thermal growth values correspond to the amount each shaft movesin the vertical and horizontal directions directly above each foot.

NoteIf one or both machines actually experience a downward growth during operation, you can usenegative numbers for the vertical direction. If one or both machines experience a growth to the rightduring operation, you can use negative numbers for the horizontal direction.

At ProfileWhen this option is selected, you can enter vertical and horizontal thermal growth valuesat a location other than at each machine foot. Thermal growth values correspond to theamount each shaft moves in the vertical and horizontal directions at each profile location.

NoteIf one or both machines actually experience a downward growth during operation, you can usenegative numbers for the vertical direction. If one or both machines experience a growth to the rightduring operation, you can use negative numbers for the horizontal direction.

References


Gap/OffsetWhen this option is selected, you can enter vertical and horizontal thermal growth valuesusing the target gap and offset readings at the coupling. Target gap and offset readingsare then used to calculate vertical and horizontal thermal growth at each machine foot.This is the most common conversion method for specifying thermal growth targets.Gap is the difference in the coupling halves at the top and at the bottom at the specifieddiameter. If the number is greater at the top, the gap is considered to be open on thetop. If the number is greater at the bottom, the gap is considered to be open on thebottom.Offset is the difference in the coupling halves at the top. For this parameter, either thecoupling of the left machine is higher than the right machine or the coupling of the rightmachine is higher than the left machine.Face/RimWhen this option is selected, you can enter vertical and horizontal thermal growth valuesusing the target face and rim dial indicator readings. Target face and rim dial indicatorreadings are then used to calculate vertical and thermal growth at each machine foot.Reverse DialWhen this option is selected, you can enter vertical and horizontal thermal growth valuesusing the target reverse dial indicator readings. Target reverse dial indicator readings arethen used to calculate vertical and thermal growth at each machine foot.

A.10 Foot pre-checkSoft foot is a condition where all feet (typically four) of a machine component (such as amotor or gearbox), do not rest on the same plane. This condition also exists if the machinebaseplate pads (where the machine foot rests) are not on the same plane. If this conditioncontinues to exist and is not corrected, two problems will occur: It will be very difficult to align the machine. You will just be spending time trying to

move the machine into alignment but can't arrive at an acceptable alignmentcondition.

The machine will not operate properly. The component is not designed to operate ina bound condition. When this happens, binding will occur causing stress at thebearings and changing the operating clearances (inside the component). To preventbinding, you must check all the feet, even those on the machine not being moved.

Traditional methods of measuring soft foot conditions include mounting a dial indicator atthe machine foot (see figure below, on the left). The hold-down bolt is then loosened whilethe indicator is watched for movement. If the indicator moved more than a predeterminedamount (usually 0.003 inch), the foot requires correction. A shim equal to the amount ofthe indicator movement is then shoved under the foot. This method assumed that aparallel soft foot existed. However, a large percentage of problem feet are angular soft feet(see figure below, on the right).

References


Soft footFigure A-3:

Correcting this type of problem with a full shim can make the condition worse (see thefollowing figure, on the left). Correction should be determined with a set of thicknessgauges (feeler gauges). The result is usually a wedge shim (see following figure, on theright).

Correcting soft footFigure A-4:

The Laser Align Application allows you to locate the problematic feet and bypass those feetthat are good. While the hold-down bolts are individually loosened and re-tightened, thelaser and sensor will measure the shaft to shaft position. This actually measures how mucheach connection affects shaft alignment. In a perfect condition, loosening bolts should notmove the shafts at all.The following are the foot pre-check methods to evaluate the measured movement at theshafts: Soft Foot Frame Distortion Index (FDI)Although they evaluate data differently, both methods give you a sense of soft footseverity at each location. Soft Foot results are shown by the number of Xs displayed andFDI results are shown as a numerical value.

References


Soft footSoft foot evaluation provides you with a sense of severity without showing numbers.Numbers are not used because, most of the time, they are mistaken for the value of theshims, which is totally incorrect. When the numbers are calculated, they are comparedagainst the tolerance (usually 0.5 mils/inch). If a particular foot is below the tolerance, it islabeled OK. If the number is between one and two times the tolerance, it is labeled with asingle X. If the number is between two and three times the tolerance, it is labeled as XX. Ifthe number is greater than three times the tolerance, it is labeled as XXX (the more Xs,the greater the severity).The number is evaluated by taking the horizontal and vertical movement on each targetand calculating the total movement on each target. The largest movement of the two isthen divided by the distance between the laser and sensor (dimension C) to determine theangle of deflection caused by loosening a hold-down bolt. This angle is compared to thetolerance for final evaluation for that foot.The advantage of this method is that it uses a combination of horizontal and verticalmovements on the target to determine the problem feet. Experience has shown thatapproximately 20% of the soft foot conditions cause a horizontal move because of aseverely bent foot.Frame Distortion Index (FDI)Frame distortion index provides you with a sense of severity with numbers. Do not mistakethese numbers for shim values.When the numbers are calculated, they are compared against the tolerance (usuallyexcellent

Standard tolerance type is the combination of offset and angle tolerances. This tolerancetype is a direct indication of the alignment condition. Optimum alignment occurs whenoffset and angular misalignments are zero.Jackshaft tolerance type measures the two angles between the shafts. It is used when thelaser fixtures are mounted 20 or more inches apart. In these cases, Standard tolerance typeis less practical to use. Optimum alignment occurs when angular misalignment is zero.

A.12 Quick SpecQuick Spec mode allows you to make a quick check of the alignment condition of amachine with minimal setup and effort. If a machine is found to have unacceptablealignment, the procedure can be readily converted to a full alignment procedure andmachine moves calculated.

NoteQuick Spec is only available in the Advanced Laser Align program for horizontal jobs.

Quick Spec launches when at least the RPM and E dimension are entered and the otherdimensions are not entered. See Section 3.2 for more information on entering machinedimensions.In this mode, only the tolerance plot information is available since the machine moveinformation cannot be calculated without entering machine dimensions.When the Quick Spec mode is activated, the thermal growth and review results options aredisabled.After viewing tolerance plots in Quick Spec mode, you can choose to consider thealignment job as finished, retake data, align a standard machine, or align a C-face machine.
