The Pramac AC03 manual serves as the definitive reference guide for operators looking to manage, monitor, and configure the digital control panel of their Pramac generator. This control system is built on the highly regarded ComAp InteliLite platform, custom-engineered specifically to handle automated mains failure (AMF) and manual generator operations. Understanding the AC03 Controller
The AC03 acts as the primary brain of the generator. It continuously monitors critical engine and alternator parameters to safeguard the machinery while ensuring a stable power supply. Core Operator Modes
You can toggle between different functional states using the physical MODE buttons on the interface:
OFF Mode: Inhibits the engine from running entirely. This mode is necessary for safety during maintenance or prolonged non-use.
MAN (Manual) Mode: Grants you complete command to manually initiate starts and stops via physical front-panel buttons.
AUT (Automatic) Mode: Actively monitors the grid. It triggers an automated sequence to start the generator and transfer load if grid power fails.
TEST Mode: Operates the engine under controlled conditions to verify system readiness without disrupting active loads. Essential Operations Guide
To operate the controller effectively, consult official digital documents such as the Pramac AC-03 Controller Operator Guide available on Scribd. Starting the Generator Manually Switch the mode to MAN. Clear active alarms by pressing the FAULT RESET button. Press the START button to begin the pre-start sequence.
Engage the circuit breakers once the unit arrives at rated speed and voltage. Halting the Generator Press the STOP button once to start the cooling delay.
Allow the cooldown to complete before full shutdown, protecting the engine.
Press STOP again if you need to bypass the cooling timer and force an immediate stop. Parameter Monitoring and Navigation pramac ac03 manual
The backlit LCD display delivers real-time diagnostic readouts to help you prevent system overload or mechanical wear. You can use the physical UP and DOWN keys to cycle through data screens. Monitored Statistics
Mains & Generator AC: Phase-to-neutral and phase-to-phase voltages.
Current & Power: True load amperage, kW, kVA, and power factor.
Engine Metrics: Battery voltage, total operational hours, and successful start counts.
Diagnostic History: Logged event lists and historical shutdown sequences. Safety Features and Fault Management
The AC03 boasts complex sensor trip-mechanisms mapped directly to continuous safety logic. Handling Active Alarms
LED Warnings: Flashing red visual cues indicate active system alarms.
Emergency Stops: Pushing the physical e-stop activates hard lockouts.
Reset Procedure: You must mechanically pull out physical e-stop buttons and press the software FAULT RESET button to restore operations.

Pramac AC-03 Controller Operator Guide | PDF - Scribd The Pramac AC03 manual serves as the definitive
The Pramac AC03 is an advanced automatic control panel designed for power generators, often utilized in standby and manual power applications. Manufactured by ComAp and rebranded for Pramac, this controller manages the starting, stopping, and protection of the engine and alternator 🛠️ Operating Modes
The AC03 controller typically features four primary modes of operation, selectable via the front panel buttons:
The generator is disabled and will not start manually or automatically. MAN (Manual) Mode:
Allows the operator to start and stop the unit manually using the Start/Stop buttons. AUT (Automatic) Mode:
The controller monitors the mains power. It starts the generator automatically if a power failure is detected. TEST Mode:
Used to test the generator's operation under load or without load, depending on configuration. 🚀 How to Start the Generator To start your generator using the AC03 controller: Check for Alarms:
Ensure the display shows no active faults. If an alarm is present (e.g., from an Emergency Stop), press the Fault Reset Select Manual Mode: Press Start: Press the green
button. The controller will initiate a pre-start delay (for glow plugs or fuel priming) before cranking the engine. Load Connection:
Once running and stable, the circuit breakers can be closed to provide power. 📊 Monitored Parameters
The AC03 display provides real-time data regarding the generator's health and performance: Engine Data: Check water levels weekly
Oil pressure, coolant temperature, battery voltage, and engine RPM. Generator Data:
Voltage (L-L, L-N), frequency (Hz), current (Amps), and power factor (cos φ). Performance Metrics:
Total operating hours, number of successful starts, and energy consumption (kWh). ⚠️ Troubleshooting & Alarms If the unit stops or fails to start, check the Alarm List on the display. Common issues include: Emergency Stop:
Triggered if the physical E-stop button is pressed. It must be pulled out and the controller reset to clear. Low Fuel/Oil: Sensor-triggered shutdowns to prevent engine damage. Cooling Delay:
When stopping in Auto or Manual, the controller may run the engine for a "Cooling Down" period (typically 120 seconds) before fully shutting off. 💻 Advanced Configuration For technical adjustments, the AC03 supports: PC Connection:
Use an RS232-to-USB interface and "Light Edit" software to modify deep parameters or monitor the unit remotely. Access Levels:
Includes a "User" level for basic operation and an "Engineer" level (password protected) for modifying input/output configurations and protection setpoints.
For official technical documentation and specific wiring diagrams, it is recommended to visit the Pramac Support Portal or contact an authorized service center. GBL30D with AC03 controller - starting.MOV
Even with a simple charger, things go wrong. Here is how the manual directly resolves five frequent issues.
Does your AC03 have power at the socket but the light won't turn on? You blew the overload. The manual shows you the exact location of the AC Reset button (usually a small black or red protrusion near the 230V sockets). You can't find it by guessing—you need the diagram.
