Dynapac VB1105TV Plus E Paving Electrical Schematics Diagrams

On a Dynapac VB1105TV Plus E screed that lives in hot asphalt, dust, and vibration all day, electrical issues are common—especially around the heating and control systems. This electrical schematic set is what I’d pull out when a screed heater won’t come on, a temperature zone is erratic, or a control panel light keeps flickering. It lets you trace how power and signals move through the harnesses, connectors, and sensors so you can isolate the fault instead of guessing and throwing parts at it.

Applications & Use Cases

• Trace screed heating circuits to find where power is lost—breaker, relay, switch, connector, or cable.
• Map connectors and harness routing so you unplug the correct plug and avoid damaging nearby wiring.
• Verify power and ground paths at a control unit before blaming a sensor or replacing expensive modules.
• Chase intermittent faults by following the schematic and wiggling suspect harness sections under load.
• Plan clean repairs by seeing which cables are bundled together and how to route replacements safely.

FAQ

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

A: Yes, it’s practical on a tablet; you can zoom into specific circuits and keep your hands free at the machine.

Q: Is it worth printing parts of this schematic?

A: Many techs print just the relevant pages, put them in plastic sleeves, and mark them up while testing.

Safety Note

Always de-energize circuits and lock out the machine before opening panels or disconnecting harnesses.
