SUMMARY

HGM6520 controller is applicable for manual/auto synchronization system of generator and mains, which can achieve automatic start/stop, data measurement, alarm protection and “four remote” (remote controlling, remote measuring, remote communication and remote adjustment). It adopts LCD display and optional Chinese–English interface with easy operation and reliable operation. The controller owns GOV (Engine Speed Governor) and AVR (Automatic Voltage Regulator) functions. Multiple working modes can be selected, such as genset fixed active power, reactive power/power factor output, mains peak shaving and uninterruptedly restore to mains supply.

HGM6520 controller can accurately monitor various running status. When genset running is abnormal, it will disconnect bus bar and stop the genset. At the same time LCD displays the alarm information.

HGM6520 controller based on 32-bit MPU design has SAE J1939 interface which can communicate with types of ECU (Engine Control Unit) with J1939 interface. Multiple parameters, like the engine speed, water temperature, oil temperature and oil pressure can be read directly via J1939 interface and displayed in LCD. Users do not need to install a sensor. Complex connections are reduced but accurate accuracy is ensured.

PERFORMANCE AND CHARACTERISTICS

1. 32-bit MPU as the core, large LCD with back-light, optional English-Chinese display, push-button operation;
2. Multiple running states under Auto mode: AMF (Automatic Mains Failure), Island Mode, Fixed Power, Peak Shaving Mode and Load Takeover Mode;
3. Scheduling start and stop weekly/monthly. Commissioning with synchronization or without load can be chosen;
4. Through SAE J1939 interface, can directly monitor ECU;
5. RMS measuring, suitable for various occasions where electricity quantity is distorted;
6. Accurate real-time measuring and display of electrical parameter, water temperature, oil pressure, fuel level and so on;
7. Perfect mains protection: over/under frequency, over/under voltage, ROCOF and vector shift;
8. Control and protection function: automatic start/stop/synchronization, synchronous detection, load sharing and alarm protection;
9. Maintenance due warning/shutdown alarm;
10. Parameter setting: users are approved to adjust parameters. Meanwhile, the setting will be saved into the internal Flash memory and never lost even power off;
11. For the engines without J1939, temperature, pressure and fuel level sensors also can be installed and used. Sensor curve also can be user defined;
12. Contents in LCD can be defined when programmable input is active. Optional Chinese and English interface can input max. 10 Chinese characters or 20 English letters;
13. Can configure digital input as close to activate or open to activate. Can configure digital output as normally open or normally closed;
14. Logic output can be defined as continuous output or pulse output;
15. With real-time calendar, clock and hour counter;
16. Can save 99 sets of event logs in cycle which can be backtracked on the spot;
17. Multi-level password protection to avoid incorrect operations by non-professionals;
18. Parameters can be adjusted from front panel or configured via PC;
19. Power supply range: (8-35) VDC, adapt to different starting battery voltage;
20. RS485/232C communication interface uses MODBUS-RTU communication protocol to realize “four remote” of the controller;
21. Modular design, anti-flame ABS shell, plug-in terminals, embedded installation with compact structure and convenient
