iat - Argentina - Wheel Aligner / Headlamp Aimer #16435 SECTION 2.0 EV & MATIX TESTING 2.1 olling eference Unit The rolling reference unit is a reference unit and does not require certification. The camber and toe settings are purposely skewed for the purpose of testing the geometric aligner's measuring capability. The skewed settings are measured at each head of the machine both forward and backward as well as right side up and upside down during Matrix and EV Testing. This is done to confirm the machines capability of accurately measuring the rolling reference unit in all directions. The reason for using such a fixture is that the angles are fixed. Using a vehicle for testing is impractical due to variation in the suspension and steering gear and linkage play. Before using the rolling reference unit, it is very important to make sure that the tires are inflated to the proper inflation rate as specified on the tire itself. To flip the rolling reference unit it requires a forklift and a chain with hooks on each end. The proper way to flip the rolling reference unit is to lift the fixture with the chain and forklift, unclamp the lock, slowly flip the unit over and lock it, lower unit back to the ground. Maintaining the rolling reference unit is a matter of checking tire pressures, checking bolt torque and keeping the steering mechanism lubricated. 2.2 Equipment Variability Tests (EV Tests) To achieve the greatest degree of accuracy of the measurements on the geometric wheel aligner, the machine must be leveled, maintained and calibrated. To assure the accuracy of the machine readings and to correlate the machine with other alignment equipment, two types of measurement analysis tests have been developed. These tests are the EV Test (Equipment Variability Test) and the Matrix Test (Toe Matrix, Camber lip-over Matrix and Camber Non-lip Matrix). The EV Test checks the machine's ability to repeat its measurements over a period of twenty-eight cycles. The PC program for this test then calculates the percent of error based upon the range of data over four sets of seven cycles. Acceptable repeatability is achieved when the percent of error for each type of reading is ten percent or less. Percentage values above ten percent can indicate some mechanical or electrical problem in the machine's operating system or measuring heads. The Matrix Tests are tests designed to measure the accuracy of the measured toe and camber readings. Each wheel of the rolling reference unit is measured at each Measuring Head both forward and backward, and in the case of the Camber lip-over Matrix, both ight side up and upside down. The test measures the wheels at each position for three cycles, thus the need for accuracy in the EV Test. After running all the positions in the Matrix Test, the computer then calculates the actual rolling reference unit measurements and the percent of error at each of the axle positions. Acceptable accuracy exists when the percent of error at each axle position is ten percent or less. Percent values higher than ten percent can indicate machine leveling or electrical problems. Other causes of higher percent values could be differences in machine build. To compensate for the differences in build and/or set up, the computer has machine-offset capability. The offsets are minimal and help maintain machine correlation and accuracy. Large offset requirements can indicate worn out parts and/or electrical problems as well as Measuring Head Problems. On the next few pages are the long hand formulas used by the computer to calculate the percent of error and the actual measurements of the rolling reference unit.

The first step is to make sure that type 99 is set-up properly. In the vehicle parameters menu, select type 99, change description to "olling reference unit" for easy reference. If you would like to use the rolling reference unit to also test machine cycling, then parameters will have to be entered, such that the rolling reference unit will have passing values. Most rolling reference units will pass testing with the following specification values: Tolerances Description Nominal Lo Set Pt Hi Set Pt Lo Spec Hi Spec ront left toe 0 -.3.3 -.5.5 ront right toe 0 -.3.3 -.5.5 ront total toe 0 -.6.6-1 1 ear left toe 0 -.3.3 -.5.5 ear right toe 0 -.3.3 -.5.5 ear total 0 -.6.6-1 1 ront left camber 0 -.5.5-1 1 ront right camber 0 -.5.5-1 1 ront cross camber 0 -.5.5-1 1 ear left camber 0 -.5.5-1 1 ear right camber 0 -.5.5-1 1 ear cross camber 0 -.5.5-1 1 Thrust angle 0 -.3.3 -.5.5 Symmetry 0 -.2.2 -.5.5 Steering wheel angle 0 -.3.3 -.7.7 NOTE: Specifications above are only suggestions and are not necessary for EV and Matrix Testing. Next in the options tab, the wheelbase must be entered. This measurement must be in millimeters. The tire rotation periods must be entered next. The best way to measure time rotation is to; A) Put the rolling reference unit on the machine; B) Place a piece of tape on the tire side wall; C) Manually center the fixture; D) Unclamp the floating plates; E) Start the drum rollers. With a stopwatch, time ten rotations of the tire. Divide the value in seconds by ten and enter the result as the rotation period. Steering gear ratio can be left as it is. Thrust angle compensation should be unchecked (off) and symmetry compensation should be checked (on). our wheel adjust should be unchecked or off as well as any machine specific functions such as static mode, etc. After type 99 is set up, click OK and click OK in the save parameters pop up window. Close the main screen and double click the ori Automation Icon. Before starting the EV Test, make sure the printer is on line and ready for printing.

iat - Argentina - Wheel Aligner / Headlamp Aimer #16435 2.2.6 Performing The Matrix Test When selecting the Matrix Test the computer program defaults to Type 99. Make sure Type 99 is properly set up as described in "Performing the EV Test". To perform the Matrix Test, click "Tests" at the top on the main screen, scroll down to Matrix Test; scroll over to Toe Matrix or Camber lip Matrix. To save time the Toe and Camber lip Matrix can be done as one test when doing it as described here. The Matrix Test consists of three cycles (iterations) run on each of eight rolling reference unit positions. The eight rolling reference unit positions are set in six positions. Position 1 = ront axle on rear of machine, top side up, rolling reference unit position #1 Position 2 = ront axle on front of machine and rear axle on rear of machine, top side up, rolling reference unit positions #3 (front of machine) and #2, (rear of machine) Position 3 = ear axle on front of machine, top side up, rolling reference unit position #4 Position 4 = ront axle on front of machine, rolling reference unit turned around 180 degrees, top side down, rolling reference unit position #5 Position 5 = ront axle on rear of machine and rear axle on front of machine, top side down, rolling reference unit positions #6 (front of machine) and #7 (rear of machine) Position 6 = ear axle on rear of machine, top side down, rolling reference unit position #8 The best way to start is to put the olling reference unit in position #2, with all four wheels on the machine, (this will help center olling reference unit for optimum results). In the Matrix pop up window, select the #2 position, and then click the start button. The machine will run three cycles and stop. The results can be viewed as the cycles are running by clicking the results tab. After the three cycles are complete, roll the olling reference unit forward or back to Position one or three. Select the position that corresponds to the way the olling reference unit is set on the machine, (one or three). un three cycles at each position by clicking the start button. After running positions one, two, and three, roll the olling reference unit off the machine, raise the master with a forklift and chain, unlock the center tube and carefully flip over the olling reference unit and lock in position, lower the olling reference unit. Now, flip up the steering wheels and turn master around 180 degrees. oll the master back onto the machine with all four wheels on the floating plates. Select position five and start the cycles as previously described. Carefully roll the olling reference unit forward or back, select the position accordingly and start the cycles. After the last set of cycles are run, leave the olling reference unit at that position. Now, view the analysis, and print results by clicking the print button. If the Matrix Test that was just run was a Toe Matrix, close the pop-up screen. Go back up to "Tests" and scroll down and over until you can select Camber-lip Matrix Test, (if the test just run was a Camber-lip, select Toe Matrix). The Camber-lip Matrix pop-up screen should now appear. If you click the results tab, you will see values for the positions but no averages or calculations of errors. Go back to the position tab; select the position that the olling reference unit is sitting at now. Click the start button. After the machine runs three cycles, stop. Now click the analysis tab and all calculations should be configured, click the print button and print results. After all testing is complete observe the percent of error. All percentages should be ten percent or less. If the percentages are higher, inspect machine for problems. ix or repair any problems found. If no problems are found, call the equipment engineer to correct the offsets. e-run tests again and percentages should be OK. EV & Matrix Testing ori Automation Version 1.2 Page 19
