Fault Phenomenon: Bomag BF600C paver automatic material feed system fails, conveyor either runs continuously or not at all.

Troubleshooting Process:
– Checked sensor: non-contact sensor surface covered with slurry.
– Checked wiring: harness worn, short to ground.
– Checked controller: parameter settings lost.
– Checked material: material obstructing sensor.

Root Cause: The surface of the conveyor material height sensor is covered with asphalt or slurry, preventing accurate detection of material level.

Required Parts: Clean sensor surface or replace sensor.
