1OVERVIEW
MGC300 Series Genset Controller is applicable for single unit automation control to realize auto start
of single unit and AMF. The controller integrates digitalization with intelligence and applies LCD graphic
display, which is simple for operation and reliable for running.
MGC300 Series Genset Controller applies 32-bit micro-processor technology, realizing precise
measuring for various parameters, set-value adjusting, and timing, and limit value setting functions etc.
A majority of parameters can be adjusted from the front panel, and all parameters can be configured by
RS485 on PC. It has compact structure, simple wiring, high reliability, which can be used for all types of
genset automation system.
MGC300 Series Genset Controller includes true low power consumption (power off) and feign low
power consumption (awakening, but screen light not on, stop indicator flashing, not do any action).

Phase voltage (L1, L2, L3) Phase voltage (L1, L2, L3)
Frequency (Hz) Frequency (Hz)
Load
Current (Ia, Ib, Ic) Unit: A
Total active power P Unit: kW
——Mains has over volt, under volt, over frequency, under frequency, and loss of phase functions;
Gen has over volt, under volt, over frequency, under frequency, over current, over power, and
loss of phase functions;
——Precisely measure all parameter values of engines:
Temperature °C Fuel level %
Battery voltage V Accumulated running time H (max. 9999 hours)
Speed RPM Accumulated start times (max. 90000000 times, display only on PC software)
——Genset fault protection and display function;
——Controller has 4 working modes: manual, auto, stop, and test mode, and MGC310 has stop,
manual, auto modes, and MGC320 has manual, auto, stop, and test mode;
——Parameter setting function: allows users to change and set the parameters, which won't be lost
on system power off; a majority of parameters can be adjusted from front panel, and all
parameters can be configured by RS485 on PC;
——1 programmable input port, 2 fixed input ports;
——2 fixed relay output ports (fuel output, start output);
——2 programmable relay output ports;
——All parameters are adjusted digitally, improving the whole case's reliability and stability;
——Sealing gasket is designed between the closure and the control window, whose dustproof and
waterproof performance can be reached to IP65;
——Metal fixing clips are used to stable the controller;
——Modular structure design, pluggable wiring terminal, and built-in installation, make it compact in
structure and easy to install.
