Pramac Ac03 Manual -

The is a digital control panel, based on ComAp’s InteliLite technology, designed to manage and monitor generator sets. It acts as the "brain" of the unit, overseeing critical parameters like voltage, frequency, and engine speed while ensuring the generator operates within safe limits. Core Functionality & Operation

: Steady green LED signals localized frequency and voltage are stabilized within limits.

The output voltage is outside acceptable parameters. Action: Check generator AVR (Automatic Voltage Regulator). 6. Maintenance and Safety Advice

It toggles automated motorized breakers to transfer building load from the grid to the generator. 5. Fault Management and Troubleshooting pramac ac03 manual

Operating the AC03 requires familiarity with its navigation buttons and visual indicators. Control Buttons

Sends a high-current signal to the starter motor solenoid. High-Voltage AC Terminals (Sensing & Switching)

Defines the safe operating voltage window before the unit triggers a protection trip. The is a digital control panel, based on

The AC03 relies entirely on a healthy starter battery. A weak battery will cause the controller to reset or drop out during the high-crank phase of an automatic start sequence.

The internal 12V/24V battery charging alternator driven by the engine belt is not outputting correct voltage.

The Pramac AC03 is one of the most reliable and widely used digital control panels for standby and prime power diesel generators. Whether you own a Pramac GSW, GSW manual, or a customized power system, understanding the AC03 controller is essential for ensuring uninterrupted power. The output voltage is outside acceptable parameters

Ensure the battery voltage reads above 12.4V DC (for 12V systems) or 24.8V DC (for 24V systems) while standby. A weak battery can cause the AC03 microchip to reset during cranking.

: A steady green light confirms generator output is active and sitting safely within normal operational limits.
