If you provide the exact controller part number (from its label) or photos of the controller wiring terminals, I can give a pin-by-pin wiring and parameter checklist. Summary
Note: Specifications may vary based on the specific firmware version and generator model.
| Feature | Specification | | :--- | :--- | | Supply Voltage | 8V to 32V DC (Typically 12V or 24V Battery System) | | Operating Temperature | -20°C to +70°C | | AC Input | 3-Phase, Neutral connection required for accurate voltage sensing | | Communication | RS485 (Modbus RTU Protocol) | | Dimensions | Compact DIN-rail or panel mount design | | Protection Class | IP54 (Typical for the front panel mounted on canopy) |
Operating any AC01 variant is straightforward due to Pramac's consistent logic:
The display shows real-time data cyclically. For the AC01 MP, technicians can scroll through each phase's voltage and current, making it easy to identify phase imbalances or a failed utility phase.
The system acts as a bodyguard for your engine. If parameters move outside safe operating ranges (e.g., low oil pressure or high coolant temperature), the AC01 will trigger an alarm. In critical situations, it will execute an emergency shutdown to prevent catastrophic engine failure. Common alarms include: Alternator / electrical inputs:
| Feature | Standard AC01 | AC01 MP (Mains Parallel) | AC01C (Compact) | | :--- | :--- | :--- | :--- | | Display | 3.5" Graphical LCD | 3.5" Graphical LCD | 2-line Segmented LCD | | Mains Parallel | No | Yes (Grid sync & load share) | No | | I/O Expansion | Yes (via CAN expander) | Yes (via CAN expander) | None | | J1939 Support | Yes | Yes | Limited (Read only) | | Typical Use Case | Data center backup | Factory peak lopping | Construction site rental | | Price Tier | Mid-range | High-end | Entry-level |
From an installer's perspective, the AC01 is designed for DIN-rail mounting inside the generator's control panel. Wiring is via pluggable screw terminals. Key connections include:
A common installation mistake is neglecting to set the engine parameters (e.g., number of start attempts, crank rest time, cooling run time) to match the specific diesel or gas engine. The AC01 allows these to be programmed via a password-protected engineer menu.
The AC01 system often requires firmware configuration to match the specific engine (e.g., Perkins, Volvo, Yanmar). When replacing the AC01 MP or AC01C boards:
The system provides comprehensive metering capabilities, eliminating the need for discrete analog gauges.
