Dynapac CA512PD Compaction Full Schematics Diagrams (Electrical and Hydraulic)

On a CA512PD, you’re usually working in rough earthwork—building pads, roads, or embankments—where downtime is expensive. This full electrical and hydraulic schematic set is what I reach for when I need to trace circuits and oil flow instead of guessing. If, for example, the vibratory drum won’t start and the dash shows no obvious fault, I use these diagrams to follow power from the key switch through relays and sensors, and in parallel trace the hydraulic control path feeding the vibration circuit.

Applications & Use Cases

• Track down no-start or intermittent power issues by following the electrical feed from battery to loads.
• Isolate a dead function (vibration, drive, steering) by checking which valve, solenoid, or sensor is in that circuit.
• Verify proper routing after harness or hose repairs, so nothing is misconnected.
• Support retrofits or add-ons by seeing where to safely pick up power or tie into existing hydraulics.
• Cross-check parts calls with the circuit layout before ordering expensive components.

FAQ

Q: Can I use this on a tablet in the field?

A: Yes, it’s handy on a tablet so you can zoom in on specific circuits right beside the machine.

Q: Should I still print pages from it?

A: I often print the key sheets I’m using that day so I can mark test points and volt/pressure readings.

Safety Note

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