MGC120 Electronic Engine Control for Single Petrol Generator Sets Model number: MGC120 Color: MGC120 Product overview The MGC120 is an AMF module designed for automation and monitoring of a single gasoline generator set. It delivers automatic start and stop, alarm protection, and automatic transfer switch control. The controller uses a LED digital tube display with touchbutton operation. Most parameters are adjustable at the front panel and all settings can be accessed from a PC via the LINK interface with the SG72 adapter. The compact, modular design and robust materials make installation quick and reliable. Key benefits Reliable automatic control and protection for single petrol generator sets, reducing manual intervention. Quick configuration from the front panel or remotely via PC for faster commissioning and maintenance. Compact, embedded design for easy installation in control panels or enclosures. Durable construction with silicone buttons, acrylic screen protection, and antiflaming ABS housing for longterm performance in varied operating environments. Main features Measures singlephase mains and generator voltage; compatible with 50 Hz and 60 Hz AC systems. Switchable display parameters: mains voltage, generator voltage, engine cylinder temperature, generator frequency, battery voltage, accumulated running time. AMF function and mains monitoring for automatic transfer and control. Protection functions: generator undervoltage, overvoltage, underfrequency, overfrequency, low oil pressure, and start failure protection. Alarm types are indicated by LEDs and the controller executes shutdown protection when needed. Speed signal input from ignition coil primary (diode must be placed in series). Crank disconnection selectable by three conditions: generator frequency, engine speed, or speed plus generator frequency. Stepper motor control and programmable outputs for air flap management. Inputs and outputs: 2 digital inputs (default: remote start and low oil pressure) 3 fixed relay outputs (fuel output, start output, ignition control) 2 programmable transistor outputs (configurable as common alarm output, ETS control, idle speed control, preheating control, GCB close output, MCB close output, air flap blocking output) LINK communication port (requires SG72 adapter) for controller parameter settings, remote monitoring, control, and firmware upgrades. User interface: digital tube and LED display with tactile button operation. Silicone panel and buttons improve tolerance to extreme temperatures. Screen protection provided by hard acrylic material. Typical applications Backup power automation for small businesses and light commercial sites where a single petrol generator provides standby power and automatic transfer is required. Portable or temporary power installations on construction sites that need robust engine control, protection, and easy setup. Residential standby systems where automatic start/stop, low oil protection, and remote parameter adjustment are required. Technical summary Model: MGC120 Functions: AMF, automatic start/stop, alarm protection, ATS switching control Measurement: singlephase mains and generator voltage, frequency, battery voltage, engine cylinder temperature, accumulated running time Inputs: 2 digital inputs (default configuration) Outputs: 3 relay outputs, 2 programmable transistor outputs Communication: LINK port (SG72 adapter required) Construction: modular design, antiflaming ABS housing, silicone panel and buttons, acrylic screen protection The MGC120 offers a straightforward, reliable solution for automating and protecting single gasoline generator sets while allowing flexible configuration and remote management.
