SWIFT 50 GLP Sensors Installation Installing the Transducer 53
If Zero Algorithm=3
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 calibration file (xxxxx.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).
6. Elevate the vehicle with a lift, or raise each corner with a jack.
7. Perform the zero procedure on each corner of the vehicle. Both the angle
and bridge zeros are computed by rotating the tire.
A. Push either the Angle Zero or Bridge Zero button on the front of the
TI box. Both indicators will light.
B. Rotate the tire 1 1/4 to 2 revolutions, until both the Angle Zero and the
Bridge Zero indicators start flashing. Follow the guidelines in
,
“Considerations for rotating a tire,” on page 45.
