Product Overview:
HMB9700 paralleled genset controller is designed for manual/auto parallel system generators with similar or different capacities. Additionally, it is suitable for single unit constant power output and mains paralleling to realize automatic start/stop, parallel running, data measurement, alarm protection as well as remote control, remote measurement and remote communication functions.

HMB9700 paralleled genset controller utilizes GOV (Engine Speed Governor) and AVR (Automatic Voltage Regulator) control functions, and the controller is able to synchronize and share load automatically; it can be used to parallel with other HMB9700 controllers. Controller can precisely monitor all operation statuses of genset. When abnormal condition occurs, it splits bus and shuts down the genset, simultaneously the exact failure mode information is indicated by the LCD display on the front panel. SAE J1939 interface enables the controller to communicate with various ECU (ENGINE CONTROL UNIT) which fitted with J1939 interface.

HMB9700 paralleled genset controller can handle complex applications due to its controller redundancy function, MSC redundancy function, comprehensive fault protection function and flexible scheduled start/stop functions. It can be widely used in all types of automatic gen-set control system with compact structure, advanced circuits, simple connections and high reliability.


With ARM-based 32-bit SCM, high integration of hardware and more reliable;

2 RS485 communication ports, which can realize " three remotes" functions by MODBUS;

CAN BUS port, which can connect with ECU with J1939, which not only can monitor usual data ( water temperature, oil pressure, speed, fuel consumption etc.), but also can control start/stop/speed raising/speed dropping etc.

Suitable for 3-phase 4-wire, 3-phase 3-wire, single phase 2-wire, and 2-phase 3-wire systems with voltage 120/240V and frequency 50/60Hz;

Collects 3-phase voltage of Bus/Gen, Bus/Gen frequency, Gen 3-phase current, Gen power parameter and Gen voltage harmonic parameters;

For Bus, controller has loss of phase and phase sequence wrong detection functions; For generator, controller has over voltage, under voltage, over frequency, under frequency, high unbalanced voltage, high total harmonic distortion, over current, earth fault, high unbalanced current, low power factor, over power, reverse power, loss of excitation, loss of phase, phase sequence wrong detection functions;

Synchronization parameters: voltage difference between bus and mains, frequency difference between bus and mains, phase difference between bus and mains;

Multiple running modes in auto state: on load running, off load running, demand parallel running;

Ramp on and ramp off function in paralleling/splitting;

3 fixed analogue sensor inputs (temperature, oil pressure and liquid level);

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

Oil pressure sensor and configurable sensor input 1 can directly connect with resistive/current/voltage sensors, while other sensor inputs can only connect with resistive sensors, and for connecting voltage/current sensors, please make it clear before the order;

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

Precisely collect various engine parameters, including temperature, engine oil pressure, fuel level, speed, battery voltage, charger voltage, total running time and total start times;

Control and protection function: automatic start/stop of the diesel genset, ATS(Auto Transfer Switch) control and perfect 2-class fault indication and protection function etc.;

Parameter setting function: parameters can be modified by users and stored in internal EEPROM memory, and cannot be lost even in case of power outage; most of them can be adjusted from the front panel on the controller and all of them can be modified on PC by RS485 ports;

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

Wide power supply range DC(8~35)V, suitable for different starting battery voltage environment;

Event log, real-time clock, scheduled start & stop function (allowing to start the genset once a day/week/month with load or not);

Alarm data record function, which allows to record the genset data of 5 alarms;

Accumulative total run time of A and B and total electric energy of A and B; Users can reset it as 0 and re-accumulative the value, making convenience for users to count the total value as they wish;

Heater, cooler and fuel pump control functions;

Maintenance function; From maintenance time to actions can be set;

All parameters apply digital adjustment, getting rid of conventional analogue modulation with normal potentiometer, and improving genset reliability and stability;

Modular structure design, self-extinguishing ABS plastic shell, pluggable terminal, guide real or screw mounting, compact structure with easy installation;
