2  PERFORMANCE AND CHARACTERISTICS 
 HGM400 series controller has two types: 
HGM410:  ASM  (Automatic  Start  Module),it  controls  generator  to  start/stop  by 
remote signal; 
HGM420: AMF (Auto Mains Failure), updates based on HGM410, moreover, has 
mains electric quantity monitoring and mains/generator automatic transfer control 
function, especially for automatic system composed by generator and mains. 
 132x64  LCD  with  backlight,  selectable  language  interface  (Chinese,  English, 
Spanish, Turkish and Russian), push-button operation; 
 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, current, power parameter and frequency of 
generator or mains.
