Dynapac SB30 Paving Electrical Schematics Diagrams

Out on a paving job, the SB30 lives in heat, dust, vibration, and constant stop‑and‑go work. This electrical schematic set is what I grab when a control quits, a sensor acts up, or a light won’t behave and I need to trace the circuit instead of guessing. If, for example, the screed controls cut out only when you swing the auger or hit a work light, these diagrams let me follow the wiring, find the shared power or ground, and isolate the weak connector or broken wire.

Applications & Use Cases

• Track power and ground paths to valves, sensors, and switches so you can verify supply instead of swapping parts blindly.
• Trace harness routing along the machine to locate hidden junctions, splices, and connectors for inspection or repair.
• Map which switches feed which solenoids to diagnose intermittent control issues under vibration or heat.
• Cross‑check connector IDs and wire colors when repairing damaged looms or installing replacement components.
• Plan safe test‑light or meter checks so you don’t backfeed a control module or short a circuit.

FAQ

Q: Can I use this on a tablet at the jobsite?

A: Yes, it works well digitally; you can zoom in on connector callouts and follow circuits without carrying a stack of paper.

Q: Is it worth printing parts of it?

A: Many techs print the key diagrams, laminate them, and keep them in the service truck for quick reference next to the machine.

Safety Note

Always lock out the machine and verify circuits are de‑energized before probing or disconnecting any electrical connectors.
