    What is the function of AMF in generator controller?

    AMF: Loss-of-voltage self-start control. It automatically starts the generator set to provide power in case of a power or phase loss in the grid. Once the grid is restored, the generator set automatically unloads and shuts down.

    The main classification of diesel generator set controllers

    As the central control unit of a diesel generator set, the generator set controller accurately monitors and regulates the technical parameters of the generator set. The generator set controller can be categorized into three types: single machine controller, parallel controller, and genset dual power controller.

    The single diesel generator set controller is the most commonly used product in generator sets. It generally includes functions such as start-up, parameter detection, alarm, and shutdown, which fully meet the requirements of a single generator set installation and usage standard. The biggest advantage of the stand-alone controller is its simplicity of operation.

    The diesel generator set parallel controller is mainly used when two or more units run simultaneously. It features automatic synchronization, automatic load distribution, voltage sag adjustment, and many other functions, effectively addressing the shortcomings of manual parallel operation. Compared with the single-unit controller, the parallel controller is more comprehensive in functionality.

    The diesel generator set dual power controller is mainly used in units equipped with dual power switches. It includes functions such as utility detection and power shutdown, and is widely used in automated units. This product is highly preferred by generator set users.

    How does the ATS generator controller start the generator?

     In the event of utility power loss or phase loss, overvoltage, undervoltage, or other abnormal conditions, the ATS system will initiate the standby diesel generator set according to the pre-set confirmation delay for utility power loss. Once the generator set confirms normal output voltage, the system will automatically switch to the generator set to power the load. When utility power is restored to normal, the system will switch back to resume utility power supply to the load after a pre-set confirmation delay. After the generator set is unloaded, it will automatically shut down after completing pre-set cooling operations.

    The composition of the generator controller?

    The generator controller serves as the central processing unit of the generator set. It is comprised of microprocessors, 32-bit display chips, industrial-grade components such as capacitors and resistors, buttons, LCD indicators, and other components. Its primary functions include engine start-up and shutdown, data measurement and display, and fault protection. Additionally, it offers power measurement, display, and protection capabilities for the generator. The controller also enables remote centralized monitoring, allowing users to remotely manage and monitor the generator’s performance through communication devices such as mobile phones or computers.

    Diesel generator set control structure and functional requirements

    The control system for diesel generators requires a specific structure and set of functions to operate intelligently alongside the utility. The following basic requirements must be met:

    (1) The control screen structure should be fixed and integrated with the unit.

    (2) The screen should include the intelligent control unit and battery pack for the diesel generator set.

    (3) Remote control capabilities should include on/off and emergency stop functions.

    (4) Telecommunication functions should allow for remote transmission of signals indicating working status (operation/shutdown) and working mode (automatic/manual).

    (5) Telemetry functions should include telemetry of three-phase output voltage, three-phase output current, battery voltage, and output power.

    (6) The control system should have a communication interface (RS-485) and be able to provide a complete communication protocol.

    (7) Automation functions should include self-start, self-input, self-protection, self-removal, and self-shutdown capabilities.
