19 Automatic Fault Detection

Explanation

Fault detected between Crane Junction Box and Bottom Arm Angle Sensor

The Bottom Arm Angle Sensor measures the angle of the bottom arm.

Causes
  • Damaged sensor cable or connector plug
  • Moisture in sensor connecting plug
  • Faulty sensor

Operator Actions
  • Check connector plug firmly seated and not damaged
  • Use override code to continue operation
  • Request service

Service Tasks
  • Check sensor cable and connector plug.
  • Replace the sensor. The orientation of the sensor is important and the cable should point upwards. Recalibrate using procedure SL0005.
  • Check the calibration by hanging a plumb bob from the D-Pin and position the bottom arm in the vertical position so that the D-Pin is vertical to the A-Pin.
  • With the diesel engine not running but SMARTlift switched on, go to Manufacturers Area – View Pin Distances-View Front or Rear Pin Distances-View Horizontal Distance AD. The distance should be zero +/- 10mm.
  • Remember, all angle sensors are the same component so it is possible to swap sensors in order to help diagnose faulty wiring or a faulty sensor. Just remember to recalibrate any sensor that is moved!
