HGM8152 Genset Parallel (with Mains) Controller is especially designed for extremely high/low temperature environment (-40~+70)°C. It applies self-luminous Vacuum Fluorescent Display (VFD) and electronic components with extreme high/low temperature resistance, therefore it can work reliably under extreme temperature condition. After careful consideration for the electromagnetic compatibility on different occasions in designing process, it provides strong guarantee for it to work under complex electromagnetic interference environment. It is plug-in wiring terminal structure, which is convenient to product maintenance and upgrade. Chinese, English, and other various languages can be displayed on controller.

HGM8152 Genset Parallel (with Mains) Controller possesses GOV (Engine Speed Governor) and AVR (Automatic Voltage Regulator) control function, and multiple running modes with Mains parallel. For example, constant active power/reactive power/power factor outputs of genset, mains peak-clipping function, and ceaseless mains supply recover function. This realizes genset automatic start/stop, parallel running, data measurement, alarm protection and "three remotes" functions. Controller can precisely monitor all kinds of working statuses of genset, and when genset is abnormal, controller shall automatically parallel off from the bus, stop the genset, and display fault information. Controller carries SAE J1939 port, which can communicate with multiple ECUs (Engine Control Unit) with J1939 port. It employs 32-bit micro-processor technology, realizing functions of precise measuring for most parameters, set value adjustment, timing and fixed value adjustment etc. Most parameters can be regulated from front panel, and all parameters can be adjusted via USB on PC. And parameters can also be regulated and monitored via RS485 or Ethernet on PC. It has compact structure, simple wiring, high reliability, and can be used widely in various genset automatic parallel system.


With ARM-based 32-bit SCM, it has high integration of hardware, and reliability is promoted to a great degree.

Large screen of graphic dot-matrix VFD, Chinese/English are optional, and can be selected on site, which provides convenience for debugging persons.

Acrylic material of hard screen for protection, with better wear resisting and scratch resistant performance;

Silicon panel and button, which makes it have stronger adaptability for high/low environment;

RS485 communication port, which can realize "three remotes" function with ModBus protocol;

Ethernet communication port, realizing Ethernet monitoring (it needs to use controller with Ethernet port);

SMS function, which can automatically send alarm information to pre-set 5 phone numbers when there is alarm occurred, and can also control and check genset status by texts;

CAN BUS port, which can connect ECU with J1939; this not only can monitor normal data (water temperature, oil pressure, speed, and fuel consumption etc.) of ECU, but also can control start, stop, speed raising, and speed dropping etc. via CANBUS port (it needs to use controller with CANBUS port);

Suitable for (120/240V) power, 50/60Hz system of 3-phase 4-wire, 3-phase 3-wire, single phase 2-wire, 2-phase 3 wire;

Collect and display 3-phase voltage, 3-phase current, frequency, and power factor of genset;

Collect and display 3-phase voltage, 3-phase current, frequency, and power factor of mains;

Complete mains parallel off protection function, over frequency, under frequency, over voltage, under voltage, frequency change ratio, vector change;

Detection functions of over voltage, under voltage, over frequency, under frequency, over current, over power, reverse power, loss of phase, reverse phase sequence for genset;

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

2 programmable analog sensors can be set to temperature, pressure, or level sensor;

Precisely collect all kinds of engine parameters:

  Temperature WT               °C/°F display can be selected;

  Oil Pressure                 kPa/psi/bar display can be selected;

  Fuel Level                   Unit: %;

  Speed                        Unit: r/min;

  Battery Voltage              Unit: V;

  Charger Voltage              Unit: V;

  Timer                        65535 hours are available;

  Accumulated Start Times      max. 65535 times are available;

Control protection function: realizing diesel genet auto start/stop, breaker close/open (switch transfer), and thorough fault display protection functions;

All outputs are relay outputs;

Parameter setting function: allowing users to change and set parameters, and this will be restored in internal FLASH memory, and will not lose at power outage. A majority of parameters can be adjusted on front panel, and all parameters can be regulated by USB port on PC, or by RS485/Ethernet port on PC;

Diverse temperature, voltage, level sensor curves can be used directly and sensor curves can also be users defined;

Multiple crank disconnect conditions can be selected (Gen frequency, speed, oil pressure);

Power supply range DC(8-35)V, which can suit different starter battery voltage environment;

Event Log, Real Time Clock, Scheduled Start/Stop(once per month/week/day, and loading or not can also be set) functions;

Can be used as indicating instrument (only indication, alarm and relay doesnt act);

Maintenance function, maintenance time due can be set;

All parameters are adjusted by digitalization, getting rid of analog adjustment of traditional potentiometer, improving reliability and stability of whole controller;

Sealing gasket is designed between enclosure and panel window; waterproof level is IP55;

Metal clips are used to fix the controller, which has outstanding performance in high temperature;

Modular structure design, pluggable wiring terminal, build-in installation with compact structure and easy mounting features;

Accumulated running A and B, Accumulated power A and B; Users can clear up the accumulations, which makes convenience for users to operate by themselves;
