Pramac Ac03 Manual

Magnetic or current transformer (CT) inputs for overload protection.

: Green LEDs indicate if the generator or mains voltage is within acceptable limits (Gen-set voltage OK / Mains voltage OK). Fault Reset : A button dedicated to acknowledging and clearing alarms. Monitoring & Data Display pramac ac03 manual

A solid red LED indicates internal failure (e.g., shorted output transistor or swollen capacitor). The manual explicitly states: "Do not attempt to repair – return to authorized service center." Opening the unit exposes lethal DC bus capacitors (up to 400V). Magnetic or current transformer (CT) inputs for overload

When a fault occurs, the AC03 stops the generator and displays a visual alarm code or icon on the LCD screen. Critical Fault Codes Alarm: Low Oil Pressure Monitoring & Data Display A solid red LED
