Test Track Vehicle for Slip Ring Sensor
Installing the Transducer
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).
Note If the anti-rotate assembly interferes with the mounting of the digital
inclinometer, use the alternate mounting location shown.
D. Place the digital inclinometer on the bracket and rotate the tire until the
inclinometer reads 0.0°, ±0.1° (or 90.0°, ±0.1° if the alternate position
is used.
E. Push the Angle Zero button on the front of the TI box. The Angle Zero
indicator will turn on for a few seconds, then turn off indicating that the
Angle Zero procedure is complete.
11. After completing the Bridge and Angle Zero procedures, rotate the wheel
one full revolution clockwise.
This allows the electronics to locate the index pulse for the encoder.
Note The wheel must rotate one-half revolution in the same direction and then
pass over the encoder index point before data collection is started.
