GU611A is a mains power failure auto start controller. It has two operating modes: auto/manual. It can monitor mains voltage failure and automatically start the generator for power supply. The controller displays the control and operation status of the generator set through the LCD, and measures and displays the generator output voltage, current, oil pressure, water temperature, frequency, and DC power supply voltage. It has backlight function and built-in communication port for easy operation and parameter setting.
This manual describes the GU611A self‑starting controller for generator sets. It covers the controller’s overview, physical dimensions, wiring diagram, operation panel, installation steps, control functions, measurement displays, warnings, parameter configuration, LCD menu system, and pre‑use preparation.
Technical specifications, including power supply ranges, current limits, relay outputs, and environmental limits, are listed at the end of the document, along with version information and safety warnings. This manual is written in Chinese.
