  • Page 2 TRENDSETTER™ Ever since it’s emergence in 1977, the Trendsetter™ gaging column has been the most reliable and technologically advanced column gage in the world. With both electric and air-to-electric capabili- ties, the Trendsetter™ is on the cutting edge of component and design technology while continuing to provide the user-friendly ease you’ve come to expect from all Edmunds products.

    EDMUNDS TRENDSETTER™ 2.1 ELECTRONIC GAGING 2-1.1 Preparing For Use - Electronic Gaging This opening description will be as brief as possible in an effort to minimize setup time. A more complete description of the column and it’s modules will be found later in the manual. To form a firm three point support for the column, unscrew the front screw at the bottom of the long foot and remount the foot on the front screw.

    Mount the A and B probes in the balancing fixture. Adjust each probe to its mechanical zero as observed on the Trendsetter™ bargraph display. Then with the range switch set to desired appli- cation range, and the polarity/function switches set to A+B mode, rotate the micrometer head some convenient distance.

    3.) Select the proper headers and reinsert the module. All Edmunds air tooling is marked with the full scale range for which it is intended to operate. Since overall range of air gaging is limited, the tooling is designed to operate on one scale only.

  • Page 9: 2-2.3 Mastering

    Unauthorized switching of ranges may affect the performance and linearity of the tooling. The tool- ing should be used with the following magnifications: Marked Range Air Amplification .010” /0.2mm .005” /0.1mm .002” / .05mm .001” / .02mm Med/High .0005”/ .01mm High To set the range of the module on the bargraph, turn the front panel range switch to required posi- tion using a small screwdriver inserted thru the front panel.

  • Page 10: 2-2.4 Setting To Tooling Other Than Edmunds

    Flow system tooling, which has a very shallow nozzle drop, will show very high magnification when used on a Trendsetter™. This might necessitate a change to a lower air amplification on the 3 range pin header. Differential type tooling will show a slightly lower magnification than the restriction bleed tooling, and may possibly require a high air amplification setting.

  • Page 12 CAUTION! OBSERVE HIGH VOLTAGES PRESENT WITHIN TRENDSETTER™ CABINET Main Frame Calibration Calibration consists of furnishing a +/- 2.500 volt input to the display card, and adjusting the gain pot. Before attempting, remove all plug-in modules, and observe all high voltage safety precau- tions.
  • Page 13 The Common Buss On an application that requires the output of a measuring head to be fed into more than one col- umn for adding, averaging, checking clearance, etc., the output signal from the column is fed into a common buss wired to the 25 pin I/O connectors. A 25 pin connector cable is plugged into each of the columns and feeds the signal into all columns where it may or may not be used (as required).

  • Page 14: E8001 Limit Light Module 3 Point

    The column limit lights are now set. If the Trendsetter™ is being used on a simple fixture, turn the mode switch to “manual run”. In this mode, the limit lights will go on and off as the Trendsetter™ passes the preset points.
  • Page 15 Remote Interface — Two user control lines present on the I/O connectors located on the rear panel of the Trendsetter™ mainframe, allow an external controller to command four special operating modes. These modes are as follows: 1. Reset — All latches cleared, limit lights and logic outputs off.

  • Page 16: E8007 Multipoint Classifying Module

    Input signals are conditioned using the high set, low set pots. This allows the user to compress or expand the specified display information over any portion of the Trendsetter™ scale. A front panel output connector provides an interface to program- mable controllers or external logic.

Using the “Zero” knob on the Trendsetter lower bay module, set the bargraph display to the highest position on scale where classifying is to end. If the character displayed on the E8007 is larger than desired, the magnification is too large.

    Remote Interface — Two user control lines present on the I/O connectors located on the rear panel of the Trendsetter™ mainframe, allow an external controller to com- mand four special operating modes. These modes are as follows: 1. Reset — All latches cleared, limit lights and logical outputs off.

  • Page 20: E8023 Air/Electronic Module

    E8023 - AIR/ELECTRONIC SIGNAL CONDITIONING MODULE 3-5 Functional Description The E8023 Air/Electronic module converts pneumatic pressure from air gage tooling, into a calibrat- ed electrical signal. The module contains an air/electronic transducer assembly, three selectable fixed gains, polarity reversal, inch/mm selection, a 10 position pin header allowing access to the I/O busses, and a 5 position range encoding switch to signal the readout display.
  • Page 21 The range switch is a front panel screwdriver adjustable control that provides an encoded range signal to the Trendsetter™ mainframe, and illuminates one of five front panel range indicators. The switch has no stops and may be rotated through 360° of travel. The E8023 module has 5 inch/5mm full scale ranges.

    Reinsert the mag needle valve and screw down until the point on the Trendsetter™ scale comes back to the master point. Repeat the procedure on the zero knob. By only cleaning one needle at a time, the gage setting is not lost. Re-check the mastering points before gaging.
  • Page 23 Re-assemble the needle to the body. If the threads appear to be loose, carefully spring the split threads open. This is best done using the wedge effect of the screwdriver tip. Pick one so that the spread is only slightly larger than the existing slot and do not over bend. With the valve assembled and all “O”...

    (“+” peak) reading. These two signals can now be compared in a third Trendsetter™ column equipped with a Sum & Difference module (E8026) and the actual clearance at maximum material condition can be displayed. This system will completely eliminate operator deci- sion making in determining the actual maximum and minimum readings.
  • Page 26 Setting the E8024 Module Zero Connect the Trendsetter™ column to the gaging fixture. Turn the mode switch to the “Bypass” mode. Using the max and min masters, set the magnification and zero as previously described. Install one of the masters in the gage fixture so that the bargraph is on scale. Rotate the Mode Switch to the TIR position.

  • Page 30 Figure 1 Figure 2 Front Panel Mag Adjustment The front panel mag adjustment allows for attenuation or boost of total module gain. (A-B) (A+B) Pin Header This pin header determines whether the A and B input groups will be summed together (A+B), or operated in the difference mode (A-B).
  • Page 31 Inch/MM Pin Header The inch/mm pin header determines the physical units in which the module will operate. Input Mag Pots As stated in the description, a 20 turn mag pot is connected to each of the six inputs of the module. The mag pots have an attenuation of 25:1, this allows for mixing of signals with wide differences in their magnifications or formats.

    It is desired to measure the clearance between a given I.D. and O.D. In this example, Air/Electronic modules will be used, but the same principles apply to any other module or com- bination of modules previously discussed. The setup will require three Trendsetter™ columns. Column 1 Air/Electronic E8023 - O.D. Measurement Column 2 Air/Electronic E8023 - I.D.
