6.5 Basic Steps to Running the AutoDyn
When a test is not running on the dynamometer, the eddy current control
should be set to 0%. This ensures that no current is applied to the
absorbers. Otherwise they can overheat and be damaged. The load
control can be reset to 0% by either of the following methods. 1) Press the
“Red Hand” button on the handheld before leaving the dyno unattended.
2) Go to the manual control mode on the handheld and set the load
control to 0%. Turning off the 240Vac power to the Eddy Current absorber
will remove any chance of current flow but this method should only be
used when the dyno will sit idle for long periods.
WinDyn preferences can be set up to quickly prepare the system for testing. A Test Group can
ensure the proper configuration files are loaded into the system. WinDyn can receive data from the
data acquisition system and save it into a data file with a filename and location determined prior to
running the test. Notes can also be entered and saved with the data, Specifications can be set,
and other preferences selected using one WinDyn dialog screen.
Preparing WinDyn to accept data and store it in a specific location with a filename will help identify
the stored data files. Test Description Notes will help in recognizing the customer, vehicle, and
purpose for the test. The test itself is run from the handheld. Post-test analysis is performed with
the WinDyn Stored Data Viewer. The Quick Start (Section 6.7.1) provides a reference to the test
operation. Copy this page and place it near the computer for easy viewing.
1. Select and load the desired test group file (*.tgp) via the Install Test Group icon on the
WinDyn tool bar or by pressing the F2 function key on the computer keyboard. This step is
unnecessary if the Test Group is automatically installed when WinDyn is started.
This procedure assumes the correct configuration files are included in the
test group design. It is very important that the calibration and control files
are installed. Otherwise, you will have to re-calibrate the dyno, or
manually load the saved files from the System|Install|* menu option.
Refer to the Test Group section in the WinDyn Users Guide for more
information.
A Test Group that loads a CFA without following it with a
Calibration file (CAL) will always return the dyno’s calibration to a
default (uncalibrated) state.
2. Check screen number 2 (press #2 on the computer keyboard) for the correct barometer,
Air Temp, and Humidity readings. Check the Trq1 channel to see if it indicates
0.0, +/- 3.0
lb/ft with no vehicle on the rolls. If any of these are incorrect, the dyno is not calibrated. A
calibration must be performed (see Chapter 10) or a calibration file installed that contains
the correct calibration coefficients (See Appendix A in the WinDyn Users Guide for more
information).
3. Press “S” on the computer keyboard to access the WinDyn Test Setup screen (See Figure
6-7). This dialog will set all the preferences for WinDyn to ensure proper test results.
