1 OVERVIEW 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.
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;...

Items Range Default Description when set value is 140, temp. high signal is not issued (only for temp. sensor, excluded the temp. high alarm signal of input port). When level is under this value for 10s, level Level Low Warning (0~200)% low warning is issued (only warning, not Value...
7.2 DEFINABLE CONTENTS OF OUTPUT PORTS Table 8 Definable Contents of Output Ports Items Function Description Not Used When this is chosen, output port won’t output. Includes all shutdown alarms and warnings; when there is only warning Common Alarm alarm input, alarms are not latched; when shutdown alarms occur, alarms are latched until they are reset.
8 CONTROLLER PARAMETER SETTINGS Under standby status, press at the same time, it will enter password entry screen (Fig. 4). At this moment the first digital flashes. Fig. 4 Password Entry Screen Press and the flashing number adds 1; Press and it decreases 1.
9 SENSOR SETTING Sensor types that can be connected inside controller are all resistance sensors; Parts of standard curves (Table 10) have been put inside the controller for users. If customized sensor curves are planned to use, users must set by PC software; When customized sensor curve is set, X value (resistance) must be inputted from small to big, otherwise mistake may occur;...
If there is something unusual, stop the running genset and check all wire connections according to this manual; For any other questions please contact with SmartGen service personnel. MGC300 Series Genset Controller User Manual Page 23 of 26...
11 TYPICAL APPLICATION Fig. 7 MGC310 Typical Application Diagram Fig. 8 MGC320 Typical Application Diagram CAUTION! Crank, fuel output ports shall expand big capacity relays. CAUTION! When sensor port is configured to "Digital High Input Active", hung up means high electrical level, and power positive connected is prohibited.
12 INSTALLATION 12.1 FIXING CLIPS — The controller is panel-embedded design and it is fixed by clips in installation. — Twist the fixing clip screw anticlockwise until it reaches proper position. — Pull the fixing clip backwards (towards the back of the module), ensuring two clips are right inside their allotted slots.
