HGM7100N Genset Controller 2020-09-10 Version1.2 Page 4 of 47
1 OVERVIEW
HGM7110N/HGM7120N series power station automation controllers integrating digitization,
intelligentization and network technology, are used for genset automation and monitoring control
system of single diesel unit to achieve automatic start/stop of genset, data measurement, alarm
protection functions etc. It fits with LCD graphic display, which can display Chinese, English and other
languages. It is easy to operate and reliable to use.
HGM7110N/HGM7120N series power station automation controllers adopt 32-bit micro-processor
technology, achieving precise measuring of many parameters, fixed value adjustment, time setting and
limits adjusting and etc. A majority of parameters can be configured from front panel of controller, and
all parameters can be adjusted through PC via USB port and monitored through PC software via
RS485. It can be widely used in all types of genset automation system with compact structure, simple
connections and high reliability.
2 PERFORMANCE AND CHARACTERISTICS
HGM7110N:used for stand-alone automation, and it controls generator to start/stop by remote start
signal;
HGM7120N: Added Mains monitoring and Mains/Gens Automatic Transfer (AMF) function based
on HGM7110N, especially suitable for single unit automation system composed by one way
generator and one way Mains.
Main features are as below:
32-bit ARM SCM, high integration hardware, performance getting higher improved.
132x64 LCD with backlight, interface operation of optional languages (Chinese, English and other
languages), and languages can be selected in the field, which provides convenience for debugging
personnel commissioning.
Screen protection applies hard-screen acrylic material, with better wear-resisting and
scratch-resisting features.
Silicone panel and pushbuttons, strong adaptability in extreme high/low temperature environments.
RS485 communication port, can realize “three remote functions” (remote control, remote measuring
and remote communication) by MODBUS protocol.
Suitable for 3-phase 4-wire, 3-phase 3-wire, single phase 2-wire, and 2-phase 3-wire systems with
voltage 120/240V and frequency 50/60Hz;
Collects and shows 3-phase voltage and current, power parameter and frequency of generator or
mains.
