Model: MGC120 Electronic engine controller for single gasoline generator sets Overview The MGC120 is an AMF module designed for automation and monitoring of a single gasoline generator set. It provides automatic start and stop, alarm protection, and automatic transfer switch control. The controller combines a clear LED digital tube display with touchbutton operation and supports onpanel parameter adjustment plus PC configuration via a LINK port. The MGC120 is compact, easy to install, and built for reliable continuous operation. Key benefits Automates generator operation for unattended use: automatic start, stop, and ATS control reduce manual intervention. Protects the engine and generator: integrated alarms and shutdowns guard against common faults. Simple configuration and monitoring: most parameters adjustable from the front panel, with full setup and firmware upgrade via LINK connection. Flexible outputs and inputs: supports common control and protection functions for a wide range of generator installations. Main features Compatible with singlephase mains and generator voltage measurement in 50Hz or 60Hz systems. Switchable display parameters: mains voltage, generator voltage, engine cylinder temperature, generator frequency, battery voltage, accumulated running time. Builtin mains monitoring and AMF functions for automatic transfer and synchronization tasks. Protection functions: under and over voltage, under and over frequency, low oil pressure, and start failure detection. Alarms are indicated by LED and trigger controlled shutdown when required. Air flap control using a stepper motor and programmable outputs. Speed sensing from the ignition coil primary; a series diode is required in the speed signal line. Selectable crank disconnect conditions: generator frequency, engine speed, or combined speed and generator frequency. Inputs and outputs: 2 digital inputs by default: remote start and low oil pressure. 3 fixed relay outputs: fuel output, start output, and ignition control. 2 programmable transistor outputs: configurable as common alarm, ETS control, idle speed control, preheating, GCB close, MCB close, or air flap blocking. LINK communication port compatible with SG72 adapter for parameter setting, remote monitoring, control, and firmware upgrades. User interface: digital tube and LED display with touchbutton operation. Durable construction: silicone panel and buttons for and low temperature tolerance, hard acrylic screen protection, antiflaming ABS housing, modular design, and embedded installation format for compact mounting. Technical and material highlights Model: MGC120 Display: LED digital tube with LED alarm indicators Panel: silicone buttons rated for extreme temperature environments Screen: hard acrylic protective cover Housing: antiflaming ABS plastic, modular and compact for embedded installation Communication: LINK port with SG72 adapter support Frequency support: 50Hz and 60Hz systems Typical applications Backup power automation for small businesses: automatic start and transfer to provide reliable backup power during mains outages. Remote or unattended generator sites: automatic monitoring and fault shutdown protect the generator when no operator is present. Portable and standby gasoline generator sets: compact embedded controller for OEM installations where space and reliable control are required. Why choose the MGC120 The MGC120 provides a practical balance of automation, protection, and configurable control for single gasoline generator sets. Its onpanel and PC configuration options, combined with robust inputs and outputs and temperatureresistant materials, make it suitable for a wide range of installation environments where reliable, automated generator management is required.
