Test Track Vehicle for Slip Ring Sensor

Installing the Transducer

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,”

on page 66.

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 – Low-Profile

Transducer Interface Set Zero Method,”

on page 56

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.

Attach the level bracket so that it sits on top of the transducer. Insert the
locking pin through the bracket and into the pin pilot hole on the
transducer (see the next figure).
