: Built-in logic routes provide standard engine protection (low oil pressure, high temperature) alongside optional Earth Fault Current Protection modules designed for generator electrical circuit preservation. Front Panel Interface: Buttons and Visual Indicators Understanding the front faceplate of the Pramac AC03
: Forces the generator to run on load to verify system health without waiting for an actual grid failure. 🛠️ Remote Access & Configuration

When the AC03 detects a parameter outside of safe thresholds, it will either trigger a warning (generator keeps running but alerts the user) or an absolute shutdown fault (generator stops instantly to protect components). Display Fault Code / Indicator Probable Cause Corrective Action
Let the engine run completely unloaded for . This cool-down period is vital for turbochargers and internal engine components to shed residual heat evenly. pramac ac03 manual
Monitors oil pressure, coolant temperature, engine speed, and battery voltage.
Features a high-visibility LCD display accompanied by status LEDs and tactile control buttons.
The interface features several dedicated buttons for manual and automatic control: Start/Stop : These only function in MAN (Manual)
Dedicated channels for resistive senders (oil pressure and engine temperature). : Built-in logic routes provide standard engine protection
Press the button. The corresponding LED will illuminate. Press the green START button.
: Initiates the stop sequence. Pressing it again or holding it for 2+ seconds will bypass cooling phases to force an immediate shutdown.
Note: This guide is based on the standard AC03 model. Please always consult the specific engine manual (usually Honda or Yanmar) included with your unit for exact maintenance intervals.
When utility power returns, the AC03 monitors grid stability. Once stable, it transfers the load back to the mains, runs the generator for a programmed cool-down period, and returns to standby. 3. Test Mode (TEST) 🕹️ Key Control Buttons When the AC03 detects
Q: What is the warranty period for my Pramac AC03 generator? A: Refer to the warranty section in the manual or contact the manufacturer for information.

Check the rear label. If it says "Only for lead-acid", do not use with lithium. If it has a "Li-Ion" or "LiFePO4" setting (via a jumper or DIP switch), follow the manual’s voltage chart: typically 14.2V bulk, 13.6V float. Using lead-acid algorithms on lithium will destroy the battery.
The controller relies on four standard modes that dictate how the generator responds to power failures:
