HGM7200/7100A series genset controllers are used for genset automation and monitor control system of single unit to achieve automatic start/stop, data measure, alarm protection and “three remote” (remote control, remote measuring and remote communication). The controller adopts large liquid crystal display (LCD) and selectable Chinese, English or other languages interface with easy and reliable operation. HGM7200/7100A controller adopts 32 bits micro-processor technology with precision parameters measuring, fixed value adjustment, time setting and threshold adjusting and etc. The majority of parameters can be set using front panel and all the parameters can be set using PC (via USB port) and can be adjusted and monitored with the help of RS485 ports. It can be widely used in a number of automatic genset control system with compact structure, simple connections and high reliability. HGM7X10, Auto Start Module, controls genset to start or stop automatically by remote start signal. HGM7X20, Auto Main Failure, updates based on HGM7X10, especially for automatic system composed by generator and mains. HGM7211, Auto Start Module, controls genset to start or stop automatically by remote start signal. HGM7221, Auto Main Failure, updates based on HGM7211, especially for automatic system composed by generator and mains.
