HGM7211/7221 series genset controllers are used for genset automation and monitor control system of single unit to achieve automatic start/stop, data measurement, alarm protection as well as remote control, remote measurement and remote communication function. It fit with TFT display, optional Chinese, English and other languages interface, and it is reliable and easy to use.
The powerful 32-bit Microprocessor contained within the module allows for precision parameters measuring, fixed value adjustment, time setting and set value adjusting and etc..Majority parameters can be configured from front panel, and all parameters can be configured by USB interface (or RS485) to adjust via PC. It can be widely used in all types of automatic gen-set control system with compact structure, advanced circuits, simple connections and high reliability.
PERFORMANCE AND CHARACTERISTICS:
HGM7211, Auto Start Module, controls genset to start or stop automatically by remote start signal.
HGM7221, Auto Main Failure, updates based on HGM7211, especially for automatic system composed by generator and mains.
1. With ARM-based 32-bit SCM, high integration of hardware and more reliable;
2. 480x272 TFT LCD with backlight, multilingual interface (including English, Chinese or other languages) which can be chosen at the site, making commissioning convenient for factory personnel;
3. Improved TFT LCD wear-resistance and scratch resistance due to hard screen acrylic;
4. Silicon panel and pushbuttons for better operation in high/low temperature environment;
5. RS485 communication port enable remote control, remote measuring, remote communication via ModBus protocol.
6. Equipped with SMS (Short Message Service) function. When genset is alarming, controller can send short messages via SMS automatically to max. 5 telephone numbers. besides, generator status can be controlled and checked using SMS;
7. Fitted with CANBUS port and can communicate with J1939 genset. Not only can you monitoring frequently-used data (such as water temperature, oil pressure, engine speed, fuel consumption and so on) of ECU machine, but also control start, stop, raising speed and speed droop via CANBUS port.
8. 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;
9. Collects and shows 3-phase voltage, current, power parameter and frequency of generator/mains.
10. For Mains, controller has over and under voltage, over and under frequency, loss of phase and phase sequence wrong detection functions; For generator, controller has over and under voltage, over and under frequency, loss of phase, phase sequence wrong, over and reverse power, over current functions.
11. 3 fixed analog sensors (temperature, oil pressure and liquid level);
12. 2 configurable sensors can be set as sensor of temperature or fuel level;
13. Precision measure and display parameters about Engine,
14. Protection: automatic start/stop of the gen-set, ATS(Auto Transfer Switch) control with perfect fault indication and protection function;
15. All output ports are relay-out;
16. 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 USB or RS485 ports.
17. More kinds of curves of temperature, oil pressure, fuel level can be used directly and users can define the sensor curves by themselves;
18. Multiple crank disconnect conditions (speed sensor, oil pressure, generator frequency) are optional;
19. Widely power supply range DC(8~35)V, suitable to different starting battery voltage environment;
20. Event log and real-time clock.
21. Scheduled start & stop generator (can be set as start genset once a day/week/month whether with load or not; also can be set as customer weekly in which users can set the start time separately from Monday to Sunday);
22. Selectivity configuration. Users can choose different configuration by input port.
23. Can be used on pumping units and as an indicating instrument (indicate and alarm are enable only, relay is inhibited );
24. With maintenance function. Actions (warning, shutdown or trip and stop) can be set when maintenance time out;
25. All parameters used digital adjustment, instead of conventional analog modulation with normal potentiometer, more reliability and stability;
26. Waterproof security level IP55 due to rubber seal installed between the controller enclosure and panel fascia;
27. Metal fixing clips enable perfect in high temperature environment;
28. Modular design, self extinguishing ABS plastic enclosure, pluggable connection terminals and embedded installation way; compact structure with easy mounting.
