Fault Phenomenon: Bomag BF600C paver instrument displays abnormally high screed temperature, but it is not hot.

Troubleshooting Process:
– Checked sensor: PT100 sensor open or short circuit.
– Checked wiring: wiring short to ground or open.
– Checked connector: connector water ingress, oxidation.
– Checked instrument: instrument module faulty.

Root Cause: The screed temperature sensor wiring is worn and shorted to ground, causing abnormal resistance readings, leading the instrument to misinterpret as an ultra-high temperature.

Required Parts: Repair wiring or replace temperature sensor.
