To operate the Atlas Copco QAS 250-330 JD T4i generator in parallel with the grid for exporting electricity, follow these steps:

1. Verify Generator Settings: Ensure that the gensets are programmed as Power Management System (PMS) in AUTO mode.
2. Configure Mains Controller: If a Qc Mains controller is installed, program it for the required application (AMF, LTO, FP, MPE) and set it to AUTO mode.
3. Connect Communication Cables: Link the generators using the communication cable (sockets X30 & X31).
4. Check Paralleling Setup: Verify all settings related to paralleling before starting the operation.
5. Start Generators: Generators G1 & G2 should be running at a combined load, and additional generators will start based on load demand.
6. Monitor Load and Stop Signals: The system will automatically start or stop generators based on power requirements and priority settings.
7. Enable Mains Power Export Mode: This mode maintains a constant power level through the mains breaker.

Ensure that all settings are correctly configured before initiating parallel operation.

  • Page 11: Leading Particulars

    Leading particulars General description The QAS 250-330 is an AC generator, built for continuous running at sites where no electricity is available or as stand-by in cases of interruption of the mains. The generator operates at 60 Hz, 480 V - 3 phase, 240 V - 3 phase and 240 V 1 phase. The QAS 250-330 generator is driven by a water-cooled diesel engine, manufactured by John Deere. An overview of the main parts is given in the diagram below.
