- Compaction System Integrity — a correctly functioning SPS Controlling unit keeps the roller's smoothness and compaction management system operating as intended, maintaining consistent mat quality and asphalt compaction output.

The SPS Controlling unit is the electronic control component responsible for managing the Bomag Smoothness Indicator and compaction monitoring functions on equipped tandem rollers. It processes sensor inputs and regulates compaction parameters, allowing the operator to monitor and adjust output for consistent asphalt mat quality. When this component fails or malfunctions, the machine may lose compaction data feedback, compromise mat smoothness, or trigger system faults — all of which affect job quality and machine usability until the unit is replaced.
