Installing the Transducer
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).
6. Elevate the vehicle with a lift, raise each corner with a jack.
7. Perform the zero procedure on each corner of the vehicle.
Use a digital inclinometer to zero the angle and strain gage bridges on the
transducer.
A. Rotate the tire one full revolution so that the encoder can find the zero
index mark.
Note The encoder has a red dot on the mounting flange connected to the slip-
ring bracket and a black dot on the slip-ring connector housing where it
interfaces with the mounting flange. These dots, when aligned next to
each other, indicate the index mark is under the encoder sensor.
B. Rotate the tire, as necessary, until the Fz on the axes icon (see the next
figure) printed on the transducer label is pointing up.
C. If not already assembled, attach the inclinometer to the level bracket
using the two 6-32 UNC fasteners provided.
Apply Locktite 222 to the threads on the fasteners. Torque each
fastener to 2 N•m (18 lbf•in).
D. Insert the dowel pins on the level bracket into the pin pilot holes
provided in the top or bottom of the transducer, as shown in the next
figure (the transducer is shown without the conduit bracket).
Note If the cable conduit bracket interferes with the mounting of the digital
inclinometer, use the bottom mounting location shown.
