34 ROS SmarTrax™ Calibration & Operation Manual
SENSOR STATUS
• The Yaw Sensor Status area of the screen displays the yaw sensor diagnostic information:
◦ Current Wheel Angle - An approximation of the steering inputs detected by the yaw sensor.
◦ Current Sensor Reading - The total yaw detected by the sensor.
◦ Zero Yaw Button - Recalibrates the yaw sensor to zero. The machine must be at a full stop before
recalibrating the yaw sensor. The example above shows the Zero Yaw Sensor as already been recalibrated
to 0. During normal operation, the value will likely show a value other than 0.
• If the SmarTrax system detects a SPS/WAS during calibration, the SPS Sensor Status area of the screen displays
the SPS/WAS sensor status information. If no SPS/WAS was detected, this field will remain blank.
NOTE: SmarTrax nodes 016-0173-031 and 016-0173-042 only - The SmarTrax node must be hardware version
C or higher to utilize the SPS/WAS.
◦ Left, Center, and Right - Displays sensor readings. If the sensor is repositioned or replaced, these values
should be recalibrated before operating the SmarTrax system.
◦ Current Wheel Angle - The current wheel angle detected by the SPS/WAS.
◦ Current Sensor Reading - Current value registered by the sensor.
◦ Steering Position Sensor Auto Center - When set to Active, the SmarTrax system automatically
recalibrates the SPS/WAS center position during operation to adjust for slight shifts in the sensor’s center
position. Bypassing this feature leaves the SPS/WAS center position at its current value.
NOTE: Refer to the Wheel Angle Sensor (SPS) Calibration - If Applicable section on page 20 for sensor
calibration information.
