If your AC03 utilizes a USB or RS485 communication port, check with an authorized Pramac distributor periodically for firmware updates.
In Manual Mode, the operator retains full control. Pressing the button initiates the pre-glow cycle (for diesel engines) and cranks the starter motor. The generator will run continuously until the operator presses STOP . This mode is ideal for maintenance, testing, or warm-up cycles. Automatic Mode (Auto)
The AC03 manual has a very simple troubleshooting tree. Here is the short version:
The AC03 acts as the central brain of the generator set. It continuously monitors engine parameters and alternator output, providing automatic shutdown protection if a fault occurs. Technical Overview
A list of error codes and corrective actions. 2. Front Panel Layout & Controls
Fuel relay, start relay, and auxiliary outputs.
An optional module can be integrated to detect current leakage to the ground, specifically protecting the generator equipment. Maintenance and Troubleshooting
When prompted for a password, enter the standard factory technician code (refer to your specific Pramac AC03 manual copy, as codes can vary by manufacture year).
Adjusts the duration the engine runs without load to safely lower internal temperatures before full shutdown. 5. Wiring and Terminal Connections
The output voltage is outside acceptable parameters. Action: Check generator AVR (Automatic Voltage Regulator). 6. Maintenance and Safety Advice
Crucial metric; drops indicate leaks or pump failure.
Yes – if the manual specifies "float mode" or "maintenance charger". The AC03 will automatically switch to a safe trickle voltage (13.8V) once the battery is full. However, disconnect for long-term storage (months) to avoid electrolysis.
