Performance and characteristics

HGM4000N series controller has six types:
HGM4010N/HGM4010NC/HGM4010CAN: ASM (Automatic Start Module),it controls generator to start/stop by remote signal;
HGM4020N/HGM4020NC/HGM4020CAN: AMF (Auto Mains Failure), updates based on HGM4010N/HGM4010NC/HGM4010CAN, moreover, has mains
electric quantity monitoring and mains/generator automatic transfer control function, especially for automatic system composed by
generator and mains.
1. 132x64 LCD with backlight, selectable language interface (Chinese, English, Spanish, Russian, Turkish, French, Portugal, and
Polish), push-button operation.

2. Hard-screen acrylic material been used to protect screen with great wear-resisting and scratch-resisting functions.

3. Silicone panel and pushbuttons can be used in extreme temperature environment.

4. RS485 communication interface enable “Three remote functions” (remote control, remote measuring and remote communication)
according to MODBUS protocol.

5. Equipped with CANBUS port and can communicate with J1939 genset. Not only can monitor frequently-used data (such as water
temperature, oil pressure, speed, fuel consumption and so on) of ECU machine, but also control starting up, shutdown ,raising
speed and speed droop via CANBUS port (need controller with CANBUS interface).

6. 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;

7. Collects and shows 3-phase voltage, current, power parameter and frequency of generator or mains.
Mains Generator
Line voltage (Uab, Ubc, and Uca) Line voltage (Uab, Ubc, and Uca)
Phase voltage (Ua, Ub, and Uc) Phase voltage (Ua, Ub, and Uc)
Frequency Hz Frequency Hz
Phase sequence Phase sequence
Current Ia, Ib, Ic A (unit)
Each phase and total active power P kW (unit)
Reactive power Q kvar (unit)
Apparent power S kVA (unit)
Power factor PF
Accumulate total generator power W kWh, kVarh, kVAh (unit)
Output percentage with load %

8. For Mains, controller has over and under voltage and loss of phase detection functions; for generator, controller has over and
under voltage, over and under frequency, over current and over power detection functions.

9. Precision measure and display parameters about Engine.
Temp. (WT) °C/°F both be displayed
Oil Pressure (OP) kPa/psi/bar all be displayed
Fuel Level (FL) %(unit) Fuel Quantity Left L(unit)
Speed (RPM) r/min (RPM)
Voltage of Battery V (unit)
Voltage of Charger V (unit)
Hour count accumulation
Start times accumulation

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

11. With ETS (energize to stop), idle control, pre-heat control and rise/drop speed control functions, which are all relay

12. Parameter setting: parameters can be modified and stored in internal FLASH memory and cannot be lost even in case of power
outage; most of them can be adjusted using front panel of the controller and also can be modified using PC via USB or RS485 port.

13. With multiplex input port 4 and 5. Input port 4 can be configured as switch input port or fuel level sensor; input port 5 can
be set as switch input port or programmable sensor. It can flexible application in different occasions.

14. Multiple temperature, pressure, oil pressure sensor can be used and self-defined directly.

15. With one programmable sensor can be configured as temperature, pressure or liquid level sensor. It is achieved doubl
temperature, pressure or liquid level sensor detections.

16. Multiple crank disconnect conditions (speed sensor, oil pressure, generator frequency) are optional.

17. With emergency start function.

18. With flywheel tooth number automatic recognition function.

19. Widely power supply range DC(8~35)V, suitable to different starting battery voltage environment.

20. All parameters used digital adjustment, instead of conventional analog modulation with normal potentiometer, more reliability
and stability.

21. With maintenance function. Types (date and running time) can be optional and actions (warning, shutdown or trip and stop) can
be set when maintenance time out.

22. Event log, real-time clock, scheduled start & stop generator (can be set as start genset once a day/week/month whether with
load or not). Maximum 99 event logs can be memorized.

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

24. Metal fixing clips enable perfect in high temperature environment.

25. Modular design, anti-flaming ABS plastic enclosure, pluggable connection terminals and embedded installation way; compact
structure with easy mounting.embedded installation way; compact structure with easy mounting.
