HGM9420N_HGM9420LT genset controller is used for automatic control of single genset to realize automatic start/AMF/synchronous transfer/cloud monitoring. This series of controller integrates digitalization, intelligence, and network technology. It fits with LCD graphic display, optional Chinese, English and other languages interface, and it is reliable and easy to use. 

HGM9420N_HGM9420LT genset controller applies 32-bit microprocessor technology, realizing precise measuring of many parameters, value adjusting, and timing, threshold adjusting etc. functions. A majority of parameters can be adjusted from the front panel. All parameters can be adjusted via USB or RS485 port on PC. Controller fits with SAE J1939 port, which can communicate with multiple ECU (ENGINE CONTROL UNIT) units with J1939. With compact structure, simple wiring, and high reliability, it can be used in various genset automation systems. 

HGM9420N_HGM9420LT genset controller can connect with SGE02-4G network communication expansion module, which can make genset connected with Internet. After controller is logged in cloud server, it can upload the data information (includes: GPS positioning site, altitude etc.) at real time to the corresponding cloud server. Users can monitor and check genset running status and event log at real time by mobile APP (IOS or Android), or PC similar terminal device. Network communication module has SMS message function. 



HGM9420N_HGM9420LT: fits Mains-Gen power monitoring for Mains/Gen automatic transfer control (AMF). It is used for single unit automation system formed by one Mains and one Genset. Mains can be disabled by disabling mains parameters for single unit automation. By remote start signal genset auto start and stop can be controlled. Mains can be enabled only by setting mains parameters to realize mains parameter only display; by remote start signal genset auto start and stop can be controlled. Synchronous transfer function can be enabled to realize Gen and Mains synchronous transfer function.
