1. Overview
The SmartGen HGM93XXMPU(CAN) series genset controllers are designed for automation and monitoring of single generator units. They facilitate automatic start/stop, data measurement, alarm protection, and "three remote" functions (remote control, remote measuring, and remote communication). These controllers feature a large Liquid Crystal Display (LCD) with a user-friendly interface available in multiple languages, ensuring easy and reliable operation.
Utilizing 32-bit micro-processor technology, the HGM93XXMPU(CAN) series offers precise parameter measurement, fixed value adjustment, time setting, and threshold adjustment. Most parameters can be configured directly from the front panel, while all parameters can be set, adjusted, and monitored via a PC using the USB port or RS485 port. Their compact structure, simple connections, and high reliability make them suitable for a wide range of automatic genset control systems.
The HGM9310MPU(CAN) model is intended for single automation systems, enabling auto start/stop via remote signals. The HGM9320MPU(CAN) model includes all HGM9310MPU(CAN) functionalities, plus Automatic Mains Failure (AMF) capabilities, making it ideal for systems involving both mains and generator power.
