Product Specification

High-Performance Control Module for Road Rollers & Wheel Compactors

This electronic control unit (ECU) is specifically engineered for heavy-duty road rollers and wheel compactors, serving as the central command center for machine propulsion, vibration systems, and safety interlock functions. Designed to withstand demanding construction environments, this module processes real-time signals from multiple sensors—including speed, temperature, and pressure transducers—and delivers precise commands to actuators such as proportional valves, motors, and display panels.

Key Features & Functions

1. Propulsion System Management
The module continuously monitors and regulates hydraulic flow and pressure to the drive motors, ensuring smooth acceleration, infinite variable speed control, and precise deceleration. For dual-drum or single-drum rollers, it coordinates front and rear wheel synchronization to prevent slippage or uneven tracking, improving overall machine stability.

2. Vibration System Optimization
Based on operator-selected amplitude and frequency settings, the module governs the vibration pump displacement while monitoring bearing temperatures and vibration status. In case of anomalies, it triggers automatic alerts or shutdowns to protect critical components from damage.

3. Integrated Safety & Diagnostic Capabilities
Built-in self-diagnostics store historical fault codes accessible via the instrument panel or diagnostic tools. The module continuously monitors operator presence sensors, emergency stop circuits, and brake pressure, ensuring compliance with international safety standards.

4. Advanced Communication Interface
Equipped with CAN bus protocol support, the module seamlessly exchanges data with engine ECUs, displays, GPS tracking devices, and fleet management systems, enabling remote monitoring and efficient maintenance scheduling.

Typical Applications

• Asphalt pavement compaction (tandem vibratory rollers)

• Soil and aggregate base compaction (single-drum vibratory rollers)

• Landfill and dam compaction (wheel compactors)

• Multi-mode operations requiring rapid switching between forward/reverse, vibration/static modes

Installation & Maintenance Guidelines

• Mount the module in a sealed electrical enclosure located in the cab rear or engine compartment, away from heat sources, oil spray, and severe vibration zones.

• Verify supply voltage and connector pin assignments before energizing to prevent reverse polarity or short circuits.

• Always disconnect the battery negative terminal and allow capacitors to discharge before unplugging or servicing the module.

• For communication or drive anomalies, first inspect sensor wiring and CAN bus termination resistors before replacing the module.

Compatible Systems & Components

This control module typically integrates with:

• Proportional travel valves and speed sensors

• Vibration pump proportional solenoids

• Engine RPM sensors and temperature/pressure transmitters

• Operator joysticks or potentiometers for speed and vibration settings

• Onboard displays for parameter visualization and fault annunciation

Suitable Equipment Classes

This ECU is widely adopted in medium-to-large tandem vibratory rollers, single-drum vibratory rollers, and heavy-duty wheel compactors, particularly those featuring multi-frequency vibration, automatic idling, and intelligent fault diagnosis systems.
