Dynapac SD115C Paving Full Schematics Diagrams (Electrical and Hydraulic)

On a Dynapac SD115C paver working hot mix all day on roads and parking lots, electrical and hydraulic issues can stop production fast. This schematic set lets you trace circuits and oil paths from one end of the machine to the other, so you can isolate faults instead of just swapping parts. For example, when the auger won’t run and you’re not sure if it’s a joystick, a solenoid, or a broken wire along the frame, these diagrams let you follow the signal and pressure path step by step and prove where it dies.

Applications & Use Cases

• Track a dead function (like conveyor or screed lift) from the control panel through wiring and valves to find the exact break point.
• Verify correct power and ground routing after replacing harness sections or connectors.
• Check hydraulic line routing and valve logic before cracking lines to bleed or reseal components.
• Confirm that a sensor, switch, or coil is actually in the right circuit before ordering or installing parts.
• Plan clean add‑on work (lights, beacons, cameras) without overloading or tapping the wrong circuits.

FAQ

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

A: Yes, it’s practical to keep it on a tablet so you can zoom in on symbols and follow circuits right at the machine.

Q: Is it worth printing parts of this schematic?

A: Many techs print the pages they use most, laminate them, and mark test points or hose IDs for quicker repeat diagnostics.

Safety Note

Always de-energize and depressurize systems before testing, disconnecting, or rerouting any electrical or hydraulic components.
