HGM8110A/8120A genset controllers are especially designed for extremely high/low temperature environment (-40~+70)°C. The controllers can operate reliably in extreme temperature conditions with the help of VFD display and the components that resist extreme temperature. All display information is Chinese (English is optional). Operation information, status information and faults information are all displayed which make commissioning convenience for factory personnel. Controller can be used under complex electromagnetic interference environment with the strong ability of anti-electromagnetic interference. Easy to maintain and upgrade due to the plug-in terminal.

HGM8110A/8120A genset controllers integrate digitization, intelligentization and network technology which are used for genset automation and monitor control system of single unit to achieve automatic start/stop, data measuring, alarm protection and “four remotes” (remote control, remote measuring, remote communication and remote regulating). 

HGM8110A/8120A genset controllers adopt micro-processor technology with precision parameters measuring, fixed value adjustment, time setting and threshold adjusting and etc. Majority parameters can be configured from front panel, and all parameters can be configured by RS485 interface (or RS232) to adjust via PC. It can be widely used in all types of automatic genset control system with compact structure, advanced circuits, simple connections and high reliability.

● For Mains, controller has over and under voltage, over and under frequency, loss of phase and reverse phase sequence detection functions; For generator, controller has over and under voltage, over and under frequency, over current, over and reverse power, loss of phase, reverse phase sequence detection functions;

● 3 fixed analog sensors (temperature, oil pressure and liquid level);

● 2 configurable sensors can be set as sensor of temperature, oil pressure or fuel level;

● Precision measure and display parameters about Engine,

Temp. (WT)           °C/°F both be displayed 

Oil pressure (OP)      kPa/psi/bar all be displayed

Speed (RPM)

Voltage of Charger (VD)   V (unit)

Hour count (HC) can accumulate to max. 65535 hours.

Start times can accumulate to max. 65535 times.

● Protection: automatic start/stop of the gen-set, ATS (Auto Transfer Switch) control with perfect fault display and protection function;

Fault display and protection items:

High temperature alarm

High temperature shutdown 

Low oil pressure alarm

Low oil pressure shutdown

Over speed shutdown 

Low fuel level warn

Battery voltage high warn

Battery voltage low warn

Load over current shutdown 

Fail to start alarm

Fail to stop alarm

Emergency stop alarm

Oil pressure sensor open circuit alarm 

Temperature sensor open circuit alarm

● All output ports are relay-out;

● Parameter setting: parameters can be modified and stored in internal EEPROM memory and cannot be lost even in case of power outage; most of them can be adjusted using front panel of the controller and all of them can be modified using PC via RS485/RS232 ports;

● More kinds of curves of temperature, oil pressure, fuel level can be used directly and users can define the sensor curves by themselves;

● Multiple crank disconnect conditions (speed sensor, oil pressure, generator frequency) are optional;

● Real time clock and run time accumulation function. 99 pieces of event logs can be circularly stored and inquired on the spot; also can be print or be inquired via PC;

● Scheduled start & stop generator (can be set as start genset once a week/month);

● With maintenance function. Actions (warning, shutdown or trip and stop) can be set when maintenance time out;

● Can be used on pumping units and as an indicating instrument (indicate and alarm are enable only, relay is inhibited);

● Accumulative total electric energy. Users can reset it and re-accumulate the value which make convenience to users to count the total value as their wish;

● Widely power supply range: DC (8~35)V, suitable to12/24V starting battery voltage environment;

● With international standard MODBUS communication protocol, better error checking capability, and with RS232 and RS485 (coupling isolation) communication interface, can realize functions of remote control, remote measuring, remote communication and remote regulating, facilitate remote centralized monitoring of genset;

● Waterproof security level IP55 due to rubber seal installed between the controller enclosure and panel fascia;
