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 adjustment, timing, and threshold setting functions etc. A

majority of parameters can be adjusted from the front panel, and all parameters can be configured by

RS485 port via 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 (awakened, but screen light not on, only stop indicator flashing, not do any action).

2PERFORMANCE AND CHARACTERISTICS

— Graphic LCD display (backlight), LED indicators, push-button operation;

— Acrylic material for hard screen protection;

— Wide power supply range DC (8~35)V, which can suits different environments of starting

battery voltages;

— Collect and display mains/gen 3-phase voltage, 3-phase current, frequency, and power

parameters;

Mains Gen

Line voltage (L12, L23, L31) Line voltage (L12, L23, L31)

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 collect 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

in case of system power off; a majority of parameters can be adjusted from front panel, and all

parameters can be configured by RS485 via PC;

— 1 digital input port, 2 fixed input ports;

— 2 fixed relay output ports (fuel output, starting output);

— 2 digital relay output ports;

— All parameters are adjusted digitally, improving the whole reliability and stability;

— Sealing gasket is designed between the enclosure and the control panel, 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.
