Page 25: General Description
General Description Sensor Head Description This section describes both the old and current versions of the 8215/8225 laser heads. The older version of heads can be identified by their gray front panels and black grid lines. The current version of heads have different color front panels. Head A has a gray front panel with white grid lines and blue on/off buttons, while head B has a blue front panel with white grid lines and gray on/off buttons.
Page 26 The sensor head with the laser source on top is the Master head (known as head “A”). The other head is the Slave (known as head “B”). The model number is listed on the back of each head. They can be identified by the letter A or B on the front. There are no differences between the older and current versions of the 8215/8225 laser heads with the exception of the front panels and batteries.
Page 27 The Activity LED on the front panel can be red, yellow, or green. An explanation of their meaning is shown in the following table. Table 1: LED Status Meaning Required Action Green Yellow Normal Operation - When the No Action Required Laser Head systems are all functioning properly and the laser beam from the companion...
Page 28 Table 1: LED Status Meaning Required Action Green Yellow Low battery 1st warning (sensor Recharge sensor heads. head) - The Laser Head has the ability to monitor its own battery power. The battery power is checked periodically to determine if it is below the X (flashing) minimum acceptable power.
Page 29 LED Functionality Difference Due to Dual Pass mode The functionality of the LED differs slightly from the states described in the above table when the Dual Pass mode of operation is selected. The difference lies in the LED state when the companion Laser Heads laser beam is on the PSD. In Dual Pass mode, when the laser beam is on or off of the PSD the LED will be a solid yellow, even when the beam is in the linear portion of the PSD.
Page 30: General Maintenance
• Store sensor heads in protective hard-shell carrying case when not in use. Calibration The Model 8215/8225 calibration should be checked every two years. Return the sensor heads to Emerson for a calibration check. All calibrations are NIST trace- able. Caution! Do not remove the CSI Quality label on the back of the sensor head.
Page 31: Battery Charging
Battery Charging Batteries must be charged with the Model 8211charger. The Model 8211 charger is a “smart, drop-in” charger that can provide a fast- or trickle-charge for the laser heads and analyzer. This section describes both the old and current version of the 8211 charger. The older version of the 8211 charger can be identified by its solid gray front panel.
Page 32 The current version of the 8211 charger will charge both the former and current versions of the 8215/8225 laser heads but at a slower charge rate than the older ver- sion of the 8211 charger. The former version of the 8211 charger charges the former version of the 8215/8225 laser heads, but it will only trickle charge the cur- rent version of the 8215/8225 laser heads.
Page 33 Note The discharge cycle is intended for older versions of the laser heads, powered by Nickel Cadmium (NiCad) batteries. This function is not required for the current version of the laser heads, powered by Nickel Metal Hydride (NiMH) batteries. However, use of this function on laser heads with NiMH batteries will not result in any damage to the heads or charger.
Page 34 After the Fast charging cycle has completed, the charger’s beeper sounds and the charger automatically begins trickle charging. When this condition begins, the Trickle indicator light turns on indicating that the battery is almost completely charged, or is completely charged. For the laser head batteries, the two conditions occur within a few minutes of each other.
Page 35 Note After a charging cycle begins, if that charging cycle is interrupted (e.g. disconnecting the power to the charger or removing the sensor head from the charger) the charging process described above initiates from the beginning. Therefore, if the charger cycle is interrupted while the Fast charge mode is in progress, then the charger automat- ically begins trickle charging after Pending(see below).
Page 36: Battery Usage - Laser Heads
The battery is designed to have a long life and is not intended to be replaced by the user. Replacement should be per- formed only at Emerson. Emerson recommends that the batteries be replaced after 500 charges.

Page 38: Introduction To Laser Alignment Fixtures Setup
Introduction to Laser Alignment Fixtures Setup This section takes you through a step-by-step setup of the 8215/8225 Laser Align- ment Fixtures. Before before beginning the actual machine alignment, be sure all pre-alignment checks have been completed. Warning! Prior to mounting the laser alignment fixtures on machine shafts, all switches operating the machines should be locked out.
Page 39: Attaching The Fixtures
Attaching the Fixtures This section shows how to attach and secure the mounting base, chains, align the two mounting bases by leveling, install the sensor heads, turn on the sensor heads, and center the lasers on their targets. Attaching the B821007 Carbon Steel Mounting Base The B821007 3/4 inch (19mm) wide carbon steel mounting bracket is suitable for the majority of alignment jobs where the laser fixtures can be rigidly mounted to a shaft that can be rotated freely.
Page 40: Attaching Chain To The Chain Pickup
Attaching Chain to the Chain Pickup This photograph illustrates how the chain attaches and actually clamps the shaft. The base is placed on the shaft (or coupling) and a link of the chain is slipped into the chain pickup to secure the base to the shaft. After slipping a chain link into the chain pickup, tighten the bolt at the end of the chain.
Page 41: Allowing Maximum Tightening Range
Allowing Maximum Tightening Range To allow for maximum tightening range, ensure that the chain nut is flush with the end of the chain bolt (as shown by arrow). Notice that the chain bolts are on oppo- site sides. As shown in later sections, each mounting base can be installed on either end and the chain bolts placed on either side of the shaft.
Page 42: Positioning A Mounting Base
Positioning a Mounting Base Tighten one of the mounting bases and rotate it (along with the shaft) until it is somewhat level at the top of the rotation. To tighten the mounting base, use a 9/16 inch wrench or your hand, depending on which chain tightener is being used. Caution! Do not overtighten the chain —...
Page 43: Positioning The Other Mounting Base
Positioning the Other Mounting Base With the previous mounting base still in its level position, if necessary, loosen and rotate the other mounting base until it is somewhat level with it. Tighten this base and recheck the other base to ensure that both are now level in relation to one another.
Page 44: Attaching Excess Chain
Attaching Excess Chain One of the problems with using chains as a mounting bracket is that the excess chain flops and can cause errors. CSI’s Laser Alignment Fixtures provide solutions for this problem. Two slots are provided (one on either side) to take up the slack. As shown in the following photographs, you can use either or both of the slots as needed.
Page 45 Using the L-shaped Slot Caution! Do not attach excess chain prior to tightening the mounting base chain bolts. Doing so may cause damage to the L and T-shaped slots. Attaching the Fixtures 2-25...
Page 46: Using The Chain Clip
You will almost always have a little extra chain left over. In that case, use the chain clip (part number D22745) to attach it to the previous chain loop. Emerson recom- mends that you use this clip to help prevent the chain from sliding out of the L-slot as the shafts are rotated.
Page 47: Installing A Post
Installing a Post Screw a mounting post (part number D23465) into each of the outer holes in the mounting base. Tighten each post with the supplied tightener (Phillips screw- driver) or with a 1/8 inch Allen wrench (not supplied with kit). Attaching the Fixtures 2-27...
Page 48: Mounting A Sensor Head
Mounting a Sensor Head Note The gray sensor head with the laser source on top is designated head “A”. The “B” designation is attached to the blue sensor head with the laser source on the bottom. In addition to their color difference, head A and B are identified with letters on the front panel.
Page 49 Note Longer mounting posts are not available. However, if you wish to make your own, refer to the mechanical drawing of a mounting post in the section entitled “Mounting Post (part number D23465) For Alignment Brackets” in Appendix B. Attaching the Fixtures 2-29...
Page 50: Models 821500 And 822500 Rf Laser Systems Only
Models 821500 and 822500 RF Laser Systems Only Depending on the clearance around which the laser head will be rotated, the posi- tion of the RF antenna may have to be adjusted. When the antenna is in its most upright position it extends up above the top of the laser head. Holding the antenna housing (not the antenna itself), rotate or twist the antenna down (or up depending on its starting position) to its desired position.
Page 51: Mounting The Other Sensor Head

Page 52: Communication Between The Fixtures And Analyzer
Caution! Changes or modifications not expressly approved by Emerson could void the user's authority to operate the equipment. There may be times when an RF communication between each sensor head and the analyzer is not convenient.
Page 53 A message will be displayed on the analyzer until the communication link is established. When communication using RF becomes difficult, Emerson recommends that you use the Direct Connect link as described in “Direct Connect (All Models)” on page 2-36.
Page 54: Connecting The 8000Rf Interface
Connecting the 8000RF Interface Attaching 8000RF to 25-pin Connector Install the 8000RF Interface onto the serial port of the analyzer by completing the following steps: 1. . . Ensure that the Model 2130 analyzer is turned off. 2. . . Connect the 25-pin connector of the 8000RF Interface to the RS-232 port on the Model 2130 analyzer.
Page 55 Caution! Do not rotate or twist the antenna on the 8000RF Interface. Attempting to do so will damage the unit. The Attached 8000RF Interface. Models 821500 and 822500 RF Laser Systems Only 2-35...
Page 56 Direct Connect (All Models) Direct Connect is designed for those conditions where it is difficult to communi- cate between the analyzer and the sensor heads using RF. Conditions such as building construction materials and contents, other radio systems operating in the vicinity at or near the same operation frequency, and noise generated by nearby equipment all may make RF communication unsatisfactory.
Page 57 To use Direct Connect, complete these steps: 1. . . Make sure the analyzer is turned off. 2. . . Attach the 25-pin connector of the direct connect cable to the RS232 port on top of the analyzer. 3. . . Connect the Lemo connectors of the direct connect cable to the mating straight Lemo connector on the extension cables, if applicable.
Page 58 Caution! When using any cable connector inside the sensor head connector, do not turn or twist the connector. This will shear the cable pins off (inside the connector) totally disabling the sensor head and cable. Pull the cable connector completely out of the sensor head connector before turning the cable.
Page 59 The extension cables are eight feet (2.4 meters) long. With two extension cables and the connection pigtail, the total length is 13 feet (4 meters). When standing between the sensor heads, a 22 foot (6.7 meters) span can be aligned, depending on the diameter of the shaft.
Page 60: Turn The Laser Beams On
Use of controls, or adjustments, or performance of procedures other than those speci- fied by Emerson may result in hazardous laser radiation exposure. To do so could result in serious personal injury. Always ensure that the sensor heads are mounted securely before turning on the laser beam.
Page 61: Center The Laser Beams
Center the Laser Beams Vertical Adjustment Horizontal Adjustment Center both Lasers on their associated target by adjusting the thumb wheels on the front of each sensor head. Models 821500 and 822500 RF Laser Systems Only 2-41...
Page 62: Rough Alignment Of The Laser Beams
Rough Alignment of the Laser Beams Rough alignment may be required to keep the laser beam on the target as the fix- tures are rotated. Either of these methods can be used: • Visible Beam rough alignment — utilizes the visible laser beams without the use of the analyzer •...
Page 63 The gridlines on the front panel should assist you in determining the approximate movement(s) needed to rough the machines in. Gridline spacing is 0.3 inches (7.5 mm). The following table shows recommended moves based upon the gross move- ment of the laser beam on the sensor head. Gross movements are discussed in ver- tical terms for simplicity.
Page 64 Gross Movement Recommended Machine Move at Gearbox at Motor Small Large, Angular & Offset – add shims under the inboard down Gearbox feet or remove shims from the outboard Gearbox feet. Large, Small Angular & Offset – add shims under the inboard Motor down feet or remove shims from the outboard Motor feet.
Page 65 This procedure also works when using the Dual Pass mode. Note Roughing in the machine so that the laser beam is kept on the target (PSD) as the laser fixtures are rotated can be quicker with a larger PSD (e.g. with the 20x20mm PSD on the 8225 laser fixtures). Models 821500 and 822500 RF Laser Systems Only 2-45...
Page 66: Introduction To Special Applications
Introduction to Special Applications This section covers using additional mounting blocks, mounting on large diame- ters ( shafts > 8 inches (203 mm), and using alternative mounting brackets. Nor- mally, additional blocks are used to achieve greater coupling clearance. In some cases, you may find that one (or both) of the mounting blocks must be installed on the coupling itself.
Page 67: Using Additional Mounting Blocks
Mounting a One-inch (25 mm) Block This photograph shows a 1-inch (25 mm) block being mounted onto the mounting block itself. Note Emerson recommends that you tighten all vertical mounting block cap screws to 50 in-lbs (without lubrication). Using Additional Mounting Blocks 2-47...

Page 70: Mounting One Bracket On A Coupling
Mounting One Bracket on a Coupling If at all possible, Emerson recommends that you mount the brackets on the shafts. However, this is not always possible. Occasionally, you may have to mount the bracket on a coupling. This view shows the B821007 carbon steel mounting brackets being mounted to the shaft on one side and the coupling on the other.
Page 71: Mounting On Shafts (Or Couplings) > 8-Inch
Although the mounting base itself can be used on shaft diameters up to 26 inches (660 mm), additional section(s) of chain must be used for applications greater than 8 inches (203 mm) in diameter. Emerson sells extension lengths in two-feet chain increments for the B821007 carbon steel mounting bracket (part number D22773) and the A800052 soft-mount (non-rotational) mounting bracket (part number A832001).
Page 72: Using Alternative Mounting Brackets
Using Alternative Mounting Brackets Attaching the A800052 Soft-Mount (Non-Rotational) Mounting Base The A800052 soft mount bracket was developed for machines with shafts or rotors that are too large and heavy or difficult to turn like cement kilns, rock crushers, gearboxes and hammer mills. This bracket is typically used for uncoupled align- ments where either the Manual Sweep or Dual Pass methods are being used.
Page 73 Before using, inspect the soft mount base to ensure that all eight ball bearings are tight and free of play. Screw the mounting posts into each hole in the mounting base and tighten with the supplied tightener (Phillips screwdriver) or with a 1/8 inch Allen wrench (not supplied with kit).
Page 74 To ensure measurement accuracy, the contact surfaces of the shaft (or coupling) must be free of dirt, grease, oil, etc. If cleaning is needed, Emerson recommends that you use a solvent-base cleaner. Shaft keys should be avoided to reduce errors in accuracy.
Page 75 Attaching the A8AA54 Narrow Mounting Base The A8AA54, 1/2 inch (13mm) wide, narrow bracket was developed for small machines with shaft diameters of 4 - 1/2 inches (114 mm) and below, where the shaft can be rotated freely. Top and bottom v-shaped bars clamp snugly around the shaft.
Page 76 Screw the mounting posts into each hole in the mounting base and tighten with the supplied tightener (Phillips screwdriver) or with a 1/8 inch Allen wrench (not supplied with kit). Mount the laser fixtures to the posts as described in “Attaching the B821007 Carbon Steel Mounting Base”...
Page 77 Attaching the A8AA55 Quick Mount Narrow Mounting Base The A8AA55, 1/2 inch (13mm) wide quick mount narrow bracket is a chain type bracket for optimal stability in tight spaces on a wide range of shaft sizes, where the shaft can be rotated freely. The chain assembly should be slipped into the mounting base.
Page 78 Screw the mounting posts into each hole in the mounting base and tighten with the supplied tightener (Phillips screwdriver) or with a 1/8 inch Allen wrench (not supplied with kit). Mount the laser fixtures to the posts as described in “Attaching the B821007 Carbon Steel Mounting Base”...
Page 79 Attaching the A800056 Magnetic Mounting Base The A800056 9/16 inches (14 mm) thick magnetic bracket was developed to mount on the side of couplings made of ferromagnetic material. Recommended minimum coupling diameter is 3-4 inches (75-100 mm), where the shaft can be rotated freely.

Page 103 Jackshaft tolerances are used when the laser heads are mounted 20 or more inches apart. In these cases, Standard Tolerances are the less practical to use. This method measures the two angles between the shafts. Optimum alignment occurs when the two angles are zero.
Page 104: Laser Configuration Function Keys
The location of each head is based on how the machines are viewed. It does not matter which head is put on which machine; however, the analyzer must know each head’s location. Caution! Selecting the proper configuration for the laser heads is extremely important! If the setting is wrong, all of the machine move calculations will be incorrect.
Page 105 Resend Data Use the Resend Data key to resend data from the laser heads. This key is active when the alignment method is set to Auto Sweep or Dual Pass on the Alt Laser Con- figuration screen. This option is useful if for some reason the data transfer from the heads to the analyzer was aborted before completion.
Page 106: Laser Address Selection
Laser Address Selection From the Current Addresses screen you can review, read, and set the laser head (Models 821500 and 822500 only) and the analyzer addresses. The Current Addresses screen is reached by pressing the Laser Address Selection key on the Laser Configuration screen.
Page 107 Laser addressing is necessary when using either direct connect or RF communica- tions. If one laser system (a system consists of a pair of laser heads and an analyzer) using RF communication is operating in close proximity to another laser system using RF communication, this option prevents the two from interfering with each other.
Page 108 Read Head A Address key Use the Read Head A Address key to read and set the address in Head A. To read and set the laser head addresses the direct connect cable must be attached to each of the laser heads and the analyzer first before this option is selected. After the direct connect cable is attached, turn Head A on and leave Head B turned off.

Page 125: Enter Dimensions
Enter Dimensions The Enter Dimensions screen allows you to enter the dimensions for the machine being aligned. If thermal growth is enabled, thermal growth information can also be entered from under this step. The Enter Dimensions screen is reached by pressing the Enter Dimensions key on the Main screen.
Page 126 Enter Dimensions Screen (right machine fixed) Note When a machine has been configured as a “Fixed” machine (as shown in the second figure above) the program will not require any dimensions to be entered for that machine. Although dimensions are not required for this machine, without them, no machine moves for that machine can be given.
Page 127 Dimensions can be expressed in either inches or millimeters (mm), depending on the analyzer units. The range of values that can be entered for the A, C, and E dimensions are 0.01 to 3600 inches and 0.254 to 91440 mm. The range of values that can be entered for the B, D, and F dimensions are -3600 to 3600 inches and --91440 to 91440 mm.
Page 128 If only the RPM and A, B, C, and F dimensions have been entered, then no alter- nate solutions will be available for the right machine. If only the RPM and D, E, C, and F dimensions have been entered, then no alternate solutions will be available for the left machine.

Page 131: Entering Fractions
Entering Fractions With the analyzer units set to English, the decimal “.” and forward slash “/” charac- ters can be used to enter fractional values on numeric entry screens in which these two characters are available. The decimal “.” character is used to separate the integer part from the fractional part of the numerical value.
Page 132 For example, if a fractional value of 5.3/4 is entered (shown in the screen above) it will be converted to 5.75 (shown in the screen below) when either another dimen- sion is selected or the Enter key is pressed to accept the screen and advance to the next step in the procedure.
Page 133: Quick Spec
Quick Spec Quick Spec mode allows you to make a quick check of the alignment condition of a machine with minimal setup and effort. If a machine is found to have unaccept- able alignment, the procedure can be readily converted to a full alignment proce- dure and machine moves calculated.
Page 134 After viewing the tolerance plot(s), use the Enter key to advance to the next step in the procedure. In the next step, you will be given a choice to consider the align- ment finished, retake data, align the standard machine, or align the C-face machine.
Page 135 If Align C-face Machine is selected, data remains stored and you advance to the C- face Setup screen where the machine dimensions for the flange location where moves are to be made can be entered. Once the required dimensions have been entered use the Enter key to advance to the C-face Solution screen where the align- ment condition and machine moves can be viewed.
Page 136: Entering Thermal Growth Information
Entering Thermal Growth Information Thermal growth can cause a machine alignment to change significantly as machines are started from a “cold” position and run up to operating speed (“hot” position). The Thermal Growth screens allow you to enter the amount of thermal growth both machines experience during operation.
Page 137: Growth At Feet
Growth at Feet If Thermal Growth at Feet has been defined as the thermal growth method for the job, you are able to input the amount of vertical and horizontal thermal growth at each machine foot. Enter Growth at Feet Growth in the vertical direction is displayed in the upper section of the screen while growth in the horizontal direction is displayed in the lower section of the screen.
Page 138 Note If one or both machines actually experience a downward growth during operation, then negative numbers should be used for the ver- tical direction. If one or both machines experience a growth to the right during operation, then negative numbers should be used for the horizontal direction.
Page 139: Growth At Profile
Growth at Profile If Thermal Growth at Profile has been defined as the thermal growth method for the job, you are able to input the amount of vertical and horizontal thermal growth at a location other than at each machine foot. The program uses this information to calculate the vertical and horizontal thermal growth at each machine foot.
Page 140 Note Dimension I is negative, if the location of profile P4 is closer to the coupling than the outboard feet of the left machine. When entering any of the machine dimensions, they should be measured and extended to the nearest 1/8 inch (3 mm). Refer to the Entering Fractions section on page 3-51 for information about entering fractions.
Page 141 Enter key Use the Enter key to advance to the Enter Growth at Profile screen. Enter Growth at Profile The Enter Growth at Profile screen, allows entry of the amount of vertical and hor- izontal thermal growth at a location other than at each machine foot. Growth in the vertical direction displays in the upper section of the screen, while growth in the horizontal direction displays in the lower section of the screen.
Page 142 Note If one or both machines actually experience a downward growth during operation, then negative numbers should be used for the ver- tical direction. If one or both machines experience a growth to the right during operation, then negative numbers should be used for the horizontal direction.
Page 143 The Growth at Feet screen displays the calculated vertical and horizontal thermal growth at each machine foot. Growth in the vertical direction is displayed in the upper section of the screen while growth in the horizontal direction is displayed in the lower section of the screen.
Page 144: Gap/Offset
Gap/Offset If Gap/Offset has been defined as the thermal growth method for the job, you are able to input the vertical and horizontal thermal growth using the target gap and offset readings at the coupling. This is probably the most the commonly used con- version method of specifying thermal growth targets.
Page 145 When entering any of the machine dimensions, they should be measured and extended to the nearest 1/8 inch (3 mm). Refer to the Entering Fractions section on page 3-51 for information about entering fractions. Refer to the following table for a description of each dimension. Measure Dimension Measurement Description...
Page 146 Enter key Use the Enter key to advance to the Enter Gap/Offset Target screen. Enter Gap/Offset Target The Enter Gap/Offset Target screen, allows you to enter the gap and offset thermal growth target numbers at the coupling. Growth in the vertical direction is displayed in the upper section of the screen while growth in the horizontal direction is displayed in the lower section of the screen.
Page 147 Offset is the difference in the coupling halves at the top. For this parameter, either the coupling of the left machine is higher than the right machine or the coupling of the right machine is higher than the left machine. Set Gap and Set Offset keys Use the Set Gap and Set Offset keys to enter the gap and offset thermal growth for the corresponding direction.
Page 148: Face/Rim
Face/Rim If Face/Rim has been defined as the thermal growth method for the job, you are able to input the amount of vertical and horizontal thermal growth using target face and rim dial indicator readings. This is probably the second-most commonly used, conversion method of specifying thermal growth targets.
Page 149 When entering any of the machine dimensions, they should be measured and extended to the nearest 1/8 inch (3 mm). Refer to the Entering Fractions section on page 3-51 for information about entering fractions. Refer to the following table for a description of each dimension. Measure Dimension Measurement Description...
Page 150 Change Sensor Location key Use the Change Sensor Location key, when the coupling is selected (highlighted with the red box around it), to change the side of the coupling on which the target dial indicator readings are to be taken. The sensor location determines the direc- tion (sign) of the Rim TIR (Total Indicator Runout).
Page 151 The target face and rim dial indicator readings can be expressed in either mils or millimeters (mm), depending on the analyzer units. All values must be entered before continuing. The range of values that can be entered for both the face and rim readings are -2048 to 2048 mils or -52.02 to 52.02 mm.
Page 152: Reverse Dial
Reverse Dial If Reverse Dial has been defined as the thermal growth method for the job, you are able to input the amount of vertical and horizontal thermal growth using target reverse dial indicator readings. The program will then use this information to cal- culate the vertical and horizontal thermal growth at each machine foot.
Page 153 When entering any of the machine dimensions, they should be measured and extended to the nearest 1/16 inch (1.5 mm). Refer to the Entering Fractions sec- tion on page 3-51 for information about entering fractions. Refer to the following table for a description of each dimension. Measure Dimension Measurement Description...
Page 154 Enter key Use the Enter key to advance to the Enter Reverse Dial Target screen. Enter Reverse Dial Target The Enter Reverse Dial Target screen, allows you to enter the target reverse dial indicator readings. The target reverse dial indicator readings can be expressed in either mils or milli- meters (mm), depending on the analyzer units.
Page 155: Sweep Laser Heads
The Growth at Feet screen displays the calculated vertical and horizontal thermal growth at each machine foot. Refer to the Growth at Profile section on page 3-59 for more information. Sweep Laser Heads Once all required machine dimensions have been entered, you are automatically advanced to the Sweep Laser Heads step.
Page 156: Foot Pre-Check
Foot Pre-Check The Foot Pre-Check option allows you to check the soft foot condition of the machine being aligned. Refer to “Machinery Shaft Alignment — General Overview” on page A-1 for more information. If this option is enabled for this job, the Foot Pre-Check screens will be automati- cally displayed only once as you advance through the procedure.
Page 157 Once this option has been completed, it will not be automati- cally displayed if the Sweep Laser Heads step is re-entered. Note Emerson recommends that you always check all feet before acquiring alignment data. The current laser head position (represented by a hash mark on the outer most part of the circle) is displayed graphically at the bottom of the screen.
Page 158: Foot Pre-Check Function Keys
Foot Pre-Check Function Keys (prior to starting the Foot Pre-Check) Start Use the Start key to start the foot pre-check once you have verified that all hold- down bolts are tight and positioned the laser heads. Clear All Use the Clear All key to clear all acquired data on all feet if data has been acquired and stored on any foot.
Page 159 Check Lasers Use the Check Lasers key to check the operational status of the heads. Refer to the Check Lasers section on page 3-30 for more information. Performing a Foot Pre-Check Once the Foot Pre-Check starts, a prompt displays as notification to loosen the hold- down bolt for the selected foot and wait for the data to stabilize.
Page 160 Soft Foot The Soft Foot calculation is equal to ((the magnitude of the movement of the foot) divided by (dimension C — Bracket to Sensor distance)) divided by the Soft Foot Tolerance. The default Soft Foot Tolerance = 0.5 mils / inch. If Soft Foot has been defined for the job, the data is evaluated as follows: •...
Page 161 Note Both the Soft Foot and FDI tolerance values can be changed in UltraMgr and transferred to the Advanced Laser Align program. Warning! The numbers displayed are not the required correction shims for this foot. Soft Foot and FDI corrections frequently require wedge shaped arrangements of shims to be installed.
Page 162: Acquiring Alignment Data
Foot Pre-Check Function Keys (after the Foot Pre-Check has been started) Accept Use the Accept key to accept and store the reading for the active foot. The Enter key can be used to do the same. Check Lasers Use the Check Lasers key to check the operational status of the heads. Refer to the Check Lasers section on page 3-30 for more information.
Page 163 The four point automatic mode is a more traditional style of acquiring data for alignment. The laser heads are mounted on a shaft, and the shaft is then rotated so that data can be taken when the laser heads are at the 12 o’clock (0 or 360°), 3 o’clock (90°), 6 o’clock (180°), and 9 o’clock (270°) positions.
Page 164 Sweep Methods - General Information The sweep modes use data acquired at several different angular positions. By using Emerson’s patented process, this data is translated into readings for the four clock positions. There are several advantages to the sweep method over the 4 point method of acquiring data.
Page 165: Auto Sweep
Auto Sweep If Auto Sweep has been defined as the laser alignment method for the job, the laser heads automatically acquire data using their built-in inclinometers while the shaft is rotated. The arc of rotation can vary from as little as 45° to a full 360° (one revo- lution).
Page 166 Standard Mode This mode of operation (sometimes referred to as the Unidirectional Mode) is the mode that is most often used during Auto Sweep alignments. In this mode, a direc- tion of rotation is automatically defined for data acquisition based on the first rota- tion to progress past the starting point by 20°.
Page 167 Averaging Mode This mode of operation is intended to allow multiple sampling of data in order to reduce the noise in the data by averaging all of the acquired values. In the Aver- aging Mode, a direction of rotation for the data acquisition is defined in the same manner as it is in the Standard mode.
Page 168 There are four basic steps when acquiring alignment data using Auto Sweep. Turn on and position the laser heads at the starting angle. Using the Laser Align program, initialize the laser heads. With the 2130 analyzer set aside, sweep the laser heads. Using the Laser Align program, get the acquired data from the laser heads.
Page 169 Positioning heads for Auto Sweep The first data acquisition screen for Auto Sweep, prompts you to turn on and posi- tion the laser heads at the starting angle. For this method, the position of the laser heads can be at any angular position you desire to start from.
Page 170 Foot Pre-Check key Use the Foot Pre-Check key to perform a Soft Foot or FDI check. Refer to the Foot Pre-Check section on page 3-76 for more information about performing a Foot Pre-Check. Check Lasers key Use the Check Lasers key on the Alt screen to check the operational status of the heads.
Page 171 Note A maximum of 20 reading sets (moves) can be stored on an align- ment job. If more than 20 reading sets are acquired a message is dis- played giving you the option of either discard the last reading set taken or overwriting the 20th reading set with the last reading.
Page 172 Note For the Auto Sweep and Dual Pass methods, if the laser heads have not yet been initialized and they have not been turned off since they last acquired the last set of data, the data stored in the heads can be transferred to the analyzer without having to re-sweep the laser heads.
Page 173 Note To prevent damage to the laser heads, make sure the antennas do not come into contact with obstacles (e.g. the ground or base plate) as they are being rotated. Getting data from heads During the data transfer, the previous screen shows the progress of the data transfer for each laser head.
Page 174: Manual Sweep
If the fit is unsatisfactory (less than 85%) a warning message will be displayed to inform you that the data is “Unfit”. At this point you should either repeat the data acquisition or try to manually condition or edit the data using the edit data func- tion.
Page 175 Note Both laser heads need to be turned on for this option to function properly. When setting the job up to use Manual Sweep as the Laser Align Method for acquiring data, you must also select the acquisition mode to be either Standard or Averaging and set the sample rate.
Page 176 Averaging Mode The Averaging mode of operation is intended to allow multiple sampling of data in order to reduce the noise in the data by averaging all of the acquired values. In this mode of operation, the last 20 readings are averaged. Starting Manual Sweep On the data acquisition screen for Manual Sweep, the current laser reading (in mils or mm, depending on the analyzer units) for each laser head is displayed in reverse...
Page 177: Accept Readings Key
Note A minimum of 3 data points over a 45°sweep arc are required, but Emerson recommends a minimum of 8 data points (samples) acquired over a sweep arc of at least 90°. Note For the greatest accuracy and repeatability, all readings should be acquired using the same direction of rotation.
Page 178 Foot Pre-Check key Use the Foot Pre-Check key to perform a Soft Foot or FDI check. If you choose to do one of the Foot Pre-Check procedures then the software returns a warning that any data, previously collected and contained in the current data set, is deleted by proceding with this operation.
Page 179 Note A maximum of 20 reading sets (moves) can be stored on an align- ment job. If more than 20 reading sets are acquired a message is dis- played giving you the option to either discard the last reading set taken or overwrite the 20th reading set with the last reading.
Page 180: Auto 4 Point
If the fit is unsatisfactory (less than 85%), a warning message displays to inform that the data is “Unfit”. At this point either repeat the data acquisition, or try to manually condition or edit the data using the edit data function. This built-in check helps alert you to a problem with the reliability of the colleted data..
Page 181 Note When using the Auto 4 Point method, an alternative option to increasing the number of samples (or increasing the data averaging beyond 25 samples per reading), would be to stop the laser fixtures at each of the four clock positions and allow the program to continu- ously average the data.
Page 182 In addition to the green background, the analyzer LED will flash each time a new reading is measured when the laser heads are within 5° of each other and 3° of the active cardinal position. If the Status Beeper option located under the 2130 ana- lyzer’s Home/General Setup screen is enabled you will also hear the analyzer beep each time a new reading is measured when the laser heads are within 5°...
Page 183 “Enter” is pressed after the third reading has been acquired. Using only three readings increases the likeli- hood of error and does not allow the instrument to check data validity. Emerson does not recommend using only three readings if four are available.
Page 184 Foot Pre-Check key Use the Foot Pre-Check key to perform a Soft Foot or FDI check. If you choose to do one of the Foot Pre-Check procedures, the software warns you that any previ- ously collected data in the present data collection set will be deleted. Refer to the Foot Pre-Check section on page 3-76 for more information about performing a Foot Pre-Check.
Page 185: Manual 4 Point
If the data validity is unsatisfactory a warning message displays to inform you that an unsatisfactory data validity condition exists. At this point you should repeat the data acquisition. This built-in check helps alert you to the data losing reliability in the misalignment calculations.
Page 186 When setting the job up to use Manual 4 Point as the Laser Align Method for acquiring data, you must also set the sample rate. The sample rate determines the number of data samples that are to be collected and averaged together to produce a single Laser PSD reading.
Page 187 Accept Readings key Use the Accept Readings key, when the laser head positions and data are as desired, to store the data at the active cardinal position. Each time a data point is stored the next cardinal position in the clockwise direction is selected (highlighted with the red box around it).
Page 188 Caution! To prevent damage to the laser heads, make sure the antennas do not come into contact with obstacles (e.g. the ground or base plate) as they are being rotated. Also, when performing an uncoupled alignment and the laser heads are mounted in close proximity to each other, make sure the antennas do not come into contact with each other as one laser head is rotated past the other.
Page 189 Enter is pressed and after the third reading has been acquired. Using only three readings increases the likelihood of error and does not allow the instrument to check data validity. Emerson does not recom- mend using only three readings if four are available.
Page 190 Enter key Use the Enter key to accept the data, after you have acquired it. At this point the data is checked for validity. Refer to the Data Quality section on page 3-127 for more information. If the data validity is satisfactory, and Review Results is enabled on the Alt Main screen, the software displays the Review Measurements screen.
Page 191: Dual Pass
Dual Pass If Dual Pass has been defined as the laser alignment method for the job, the laser heads automatically acquire data using their built-in inclinometers as each laser head passes by each other. Except for how the data is acquired, this method func- tions similar to Auto Sweep, but like Manual Sweep, it is useful for performing uncoupled or non-rotational alignments.
Page 192 Note The Model 800001 direct connect cable can be used to enable the laser heads to communicate with the analyzer except when using the Dual Pass method. When setting the job up to use Dual Pass as the Laser Align Method for acquiring data, you must also set the Target Window percentage.
Page 193 Note If a lower percentage (smaller valid window) is selected, a slower rota- tional speed may be required especially with a smaller PSD (e.g. with the 10x10mm PSD on the 8215). For example, a 10% Target Window would define a 2mm wide window on an 8225 and a 1mm wide window on an 8215 centered around the PSD's vertical center- line in which data will be acquired as the laser beam passes across the window.
Page 194 Initialize Lasers key Use the Initialize Lasers key to initialize the laser heads and advance to the next step in the procedure. The Enter key can be used to do the same. Foot Pre-Check key Use the Foot Pre-Check key to perform a Soft Foot or FDI check. If you choose to do one of the Foot Pre-Check procedures, the software warns you that any previ- ously collected data in the present data collection set will be deleted.
Page 195 Note A maximum of 20 reading sets (moves) can be stored on an align- ment job. If more than 20 reading sets are acquired a message is dis- played giving you the option to either discard the last reading set taken or overwrite the 20th reading set with the last reading.
Page 196 Note For the Auto Sweep and Dual Pass methods, if the laser heads have not yet been initialized and they have not been turned off since they acquired the last set of data, the data stored in the heads can be trans- ferred to the analyzer without having to re-sweep the laser heads.
Page 197 The following scenario will more clearly illustrate how the Dual Pass method oper- ates. When the analyzer initializes the laser heads, all data is cleared. The laser heads then begin detecting the presence of the other laser head’s laser beam on its PSD. If a laser beam is not on a PSD, the laser head's LED will be flashed solid yellow.
Page 198 Note A minimum of 3 data points over a 45° sweep arc are required, but Emerson recommends a minimum of 8 data points be acquired over a sweep arc of at least 90°. Note Depending on the model, make sure either the Model 821510 or 8215C2-PM cable is connected to the laser fixtures prior to initializing them.
Page 199 During the data transfer, the previous screen shows the progress of the data transfer for each laser head. When the data transfer is complete, the data is analyzed and a sine wave is fit to the data.. If the fit is satisfactory (85% and above), the program will mark the Sweep Laser Heads step back on the Main screen completed and advance you to the next step in the procedure.
Page 200 To connect the 8215C2-PM Dual Pass cable to the laser fixtures, complete these steps: Connect the Lemo connector on one end of the Dual Pass cable to the mating straight Lemo connector of the extension cable, if applicable. Connect the Lemo connector on one end of the cable to the Lemo port under the nose of one of the laser fixtures.
Page 201: Review Results
Extension cables are 8 feet (2.4 m) long. With one extension cable and the Dual Pass cable, the total length is 10 feet (3 m) allowing a 9 feet 8 inch (2.9 m) span to be aligned. Note For similar information on connecting the 821510 direct connect cable when using the Dual Pass method for direct connect communi- cation between the analyzer and the laser fixtures, refer to Direct Connect (All Models) section for more information.
Page 202 Note If you exit the Review Measurements screen before saving the aver- aged reading set, you can return to it using the Review Results key on the Alt screen of the data acquisition screens. Review Measurements Screen The Review Measurements screen contains the alignment condition, the acquisi- tion date and time, and a symbol representing the acquisition method used for each of the readings acquired.
Page 203 If the Tolerance Type is Standard, alignment angle and offset data are displayed for both the vertical and horizontal directions. If the Tolerance Type is Jackshaft, align- ment left machine angle and right machine angle data are displayed. Angle Icon Offset Icon An icon depicting the alignment method and data condition displays just to the far right of each data reading.
Page 204: Review Results (Measurements) Function Keys
Enter key Use the Enter key to save the average reading set and advance to the tolerance plot screens where graphical representations of the alignment condition can be reviewed. Note If any reading used to calculate an average reading set was acquired using Auto Sweep, Manual Sweep, or Dual Pass, the associated sine fit data will not be saved once the average reading set is saved.
Page 205 Select/Unselect Use the Select/Unselect key to select the highlighted reading (place a check mark just to the left of the reading), or if the reading has already been selected, to unse- lect the reading (remove the check mark). The selected readings are used to calcu- late the average reading set displayed at the bottom of the screen.

Y- axis and the rotational position as the X-axis), a sine wave would be formed. Even when only part of the sine wave data is collected, Emerson’s Alignment software can still curve fit a sine wave to this limited data. Called curve fitting, all values used to determine the machine moves can be obtained from the completed sine waves.
Page 207: Data Quality
If the data correlation can not be brought into the acceptable level but the peak- peak amplitude is too high, then a message will be displayed advising you to check the system for looseness and then repeat the measurement. Another possible reason for this condition could be due to data points lying too far away from the sine fit curve.
Page 208 When using any 4 point method the data is always checked for validity. In theory, subtracting any third measurement from the sum of two opposing measurements will give the value of the 4th measurement (the one opposite the third measure- ment).
Page 209: Move Machine
Move Machine Once all required data has been acquired, the screen automatically advances to the Move Machine step.

Page 281: Tolerances
Tolerances The amount of offset and angular misalignment displayed is based upon the last full set of alignment readings. All shaft misalignment is a combination of offset and angular misalignment (See “Alignment Application Notes” on page A-3.). This screen breaks down the misalignment into each component. The amount of each type of misalignment is shown for both the horizontal and vertical direc- tions (for horizontal machines).
Page 282 Optimum alignment occurs when offset and angle are zero. In most cases, that degree of accuracy is not practical. For that reason, tolerances are used to set an achievable goal. Emerson’s recommended tolerances (referenced to RPMs) are listed in the table below.
Page 283 Excellent Acceptable Offse Speed Offset Angle Angle (RPM) (mm) (mrad) (mrad) (mm) < 500 0.13 0.15 501 - 1250 0.1 0.13 1251 - 0.08 2000 2001 - 0.05 0.08 3500 3501 - 0.03 0.25 0.05 7000 > 7000 0.01 0.03 0.25 Metric Data Units Values in the table are assumed to be pure offset or pure angle.
Page 284 The curves at the lower left are the tolerances to shoot for. Depending on RPM, they can be modified in UltraMgr and then transferred to the analyzer. See “UltraMgr” on page 3-199 for more information. The alignment condition (with respect to the tolerances) can be monitored by observing the tolerance target during the live move.
Page 285 The chart above shows the Angle and Offset for a machine that operates at 2000 — 3500 RPM plotted together. A pure angle reading of 0.45 mils/inch (0.44 mrad) and a pure Offset reading of 2.5 mils (0.06 mm) are marked by the arrows. These readings are clearly in the acceptable range when looked at individually.
Page 286 Emerson’s recommended tolerances are listed in the following table. Excellent Acceptable Angle Angle Speed (mils/inch or (mils/inch or (RPM) mrad) mrad) < 500 501 - 1250 1251 - 2000 2001 - 3500 3501 - 7000 > 7000 3-206 Horizontal Alignment...
Page 287: Chapter 4 • Vertical Alignment
Chapter Vertical Alignment The vertical alignment feature of the Advanced Laser Align application is used to collect and display alignment data for machines in which the machine moves are done at the machine flange (e.g. C-face mounted motors). These consist of one machine component mounted on another, bolted together at a flange.
Page 288 Measurements should be taken with the laser system set up across the coupling to determine the offset and angle between the two shafts. Correct the angle by shim- ming in the vertical direction. The offset is corrected by sliding the machine at the flange.

Page 343: Chapter 5 • Straightness Measurements
Chapter Straightness Measurements The straightness feature found in the Advanced 2130 Laser Align application is used to determine surface profiles. This profile can be of a motor baseplate or checking the crown on a rolling application. You must use a set of laser sensor heads and mounting fixtures (CSI model 8AA50) to acquire surface profile read- ings.

Appendix Application Information Machinery Shaft Alignment – General Overview Poor shaft alignment can cause the following problems: • Bearing failure • Shaft deflection fatigue • Seal leakage and failure • Coupling failure • Internal heating • High energy consumption • Excessive vibrations (studies have shown that almost 50% of excessive vibra- tion in direct-coupled rotating equipment is due to misalignment) Proper machine alignment will result in: •...
Page 366 These types of errors are even more likely to occur when you have pressure to com- plete the job quickly. The Emerson CSI alignment equipment can help you avoid these kinds of mis- takes. Our adjustable brackets are designed to fit most machines. Since there are no axial projecting arms, bracket sag is zero.
Page 367: Alignment Application Notes
Alignment Application Notes To achieve ideal machine alignment, the shaft centerline of one machine element (such as a motor) must coincide with the centerline extension of another machine shaft (such as a pump) during operation. In more complex applications, three or more elements may be aligned in a train.
Page 368 Misalignment can occur both horizontally and vertically. Most misaligned machines have a combination of offset and angular misalignment (see following figure). Alignment Examples...
Page 369: Pre-Job Preparation And Setup
Pre-job Preparation and Setup Before starting any alignment job, the history of alignments performed on this machine(s) should be reviewed. Were any special problems found during the pre- vious alignment; if so, what were they (soft foot, piping strain, coupling problems, etc.)? How well was the machine aligned and who performed the alignment? Answering these questions along with having a predefined job setup reduces the pre-job preparation time and decreases the total time to do the job.
Page 370: Changes That Occur During Operation
Coupling Considerations Emerson’s alignment system is not affected by axial float and the effects from tor- sional play (backlash) in the coupling are minimal. However, you should ensure that the coupling is properly installed and not in such poor condition that it adversely affects the alignment process.
Page 371 Different Thermal Expansion Rate Examples The Model 2130 Laser Align program allows you to input the amount of vertical and horizontal thermal growth at each machine foot. There are several methods that can be used to calculate this growth. Alignment Application Notes...

Page 373: Appendix B • Foot Pre-Check Types
Appendix Foot Pre-Check Types Foot Pre-Check Measurement Methods – Soft Foot and Frame Distortion Index (FDI) Soft foot is a condition where all feet (typically four) of a machine component (such as a motor or gearbox) will not rest on the same plane. This condition also exists if the machine baseplate pads (where the machine foot rests) are not on that same plane.
Page 374 This method assumed that a parallel soft foot existed. However, a large percentage of problem feet are angular soft feet (similar to Fig 2). Correcting this type of problem with a full shim can make the condition worse (see Fig 3). Correction should be determined with a set of thickness gauges (feeler gauges).
Page 375 Soft Foot Evaluation The Soft 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 the shims (totally wrong). When the numbers are calculated, they are compared against the tolerance (usually 0.5 mils/inch).
Page 376 Note The tolerance can be changed in UltraMgr and downloaded to the analyzer. See “Tolerances” on page 3-193 for more information on loading tolerances to the analyzer. The number is evaluated by measuring the vertical angle and applying it to an old millwright’s “rule of thumb”.
