The steering position sensor is a two–piece assembly located on top of the rear
wheel caster fork shaft. The sensor portion includes 2 analog hall effect sensors.
The second piece of the assembly is a bolt with a magnetic head threaded into
the caster fork shaft. The steering position sensor follows the rear caster fork
movement.
The sensor operates on 5VDC supplied by the SC7: Steering motor. Signal
voltage from the steering position sensor (along with information from the
steering input device) is used by the SC7: Steering motor to determine the
appropriate direction and current flow to operate the steering motor. The steering
position sensor signals are constantly monitored for steering fault detection. If a
steering position sensor fault occurs while the machine is moving, the machine
will slowly come to a stop. The brake pedal can be used to stop the machine
sooner if necessary. A steering sensor fault will disable the traction system until
the ignition key is cycled OFF and ON.
The InfoCenter Display can be used to monitor the direction of the steering
position sensor during machine operation.
Note:
If a the steering position sensor is removed for any reason, the steering
system must be calibrated. Calibrate the steering system – center first, then
calibrate the steering system – range; refer to
Calibrating the Steering System –
and
Calibrating the Steering System – Range (page 5–91)
.
Testing the Steering Position Sensor
The steering position sensor and its circuit wiring can be tested using the
InfoCenter Display; refer to
Using the InfoCenter Display for Troubleshooting
(page 3–39)
. If testing determines that the sensor and circuit wiring are not
functioning correctly, proceed with the following test procedure:
