Installing the Transducer
H.
Push the Angle Zero button on the front of the TI box. The Angle Zero
indicator will light for a few seconds, then both the Bridge Zero and
Angle Zero indicators should turn off.
Note
If the red Fail indicator lights momentarily and the Bridge Zero and
Angle Zero indicators end up blinking slowly, problems were detected
with the zero. Try repeating the procedure. Use TISTATUS for a more
detailed explanation of the problem. If you continue to have an error,
consult the chapter
, “Troubleshooting,”
in the SWIFT 50 GLP Sensor
Product Information manual (MTS part number 100-162-722)
.
I.
Rotate the transducer slightly to update the rotational transformation.
At this point the TI should be reading absolute forces in the vehicle
coordinate system.
J.
Perform
, “Verifying the Quality of the Zero Procedure,”
K.
Look at your data acquisition system to verify that the SWIFT sensor is
gathering data.
If Zero Algorithm=1
When you zero the TI, you want the vehicle to be fairly level and the transducer
to be as close to plumb as practical.
1. Install the SWIFT sensor(s) and data collection equipment on the vehicle.
2. Connect all cables and turn on the power to the TI boxes.
3. Let the TI boxes and transducers warm up for 15-20 minutes.
4. Run the TISTATUS program to compare the supply voltages to the
reference voltages.
Type: TIstatus
If the supply voltages vary more than 0.5 V from the reference voltages,
there is a power supply problem that must be resolved before you can
continue.
5. Verify that the calibration file is set up correctly for your testing application.
A.
Download the spinning calibration file (xxxxxs.cal) to the computer
from the MTS Disk that corresponds to the serial number of the
transducer that you are setting up.
B.
If necessary, modify the zero algorithm and angle mode to fit the
application/use requirements as described in
, “Edit the Calibration
File,”
in the SWIFT 50 GLP Sensor Product Information manual (MTS
part number 100-162-722).
C.
The EncoderSize parameter should be omitted or set to EncoderSize=1
D.
Download the calibration file to the TI box.
Note
If it becomes necessary to change the zero algorithm or angle mode
after downloading the file to the TI, you can do so by using the
TISETZERO utility, as described in
, “TISETZERO – Transducer Interface
Set Zero Method,”
in the SWIFT 50 GLP Sensor Product Information
manual (MTS part number 100-162-722).
