HGM4020DC genset controller is specially designed for mobile communication base station, and its functions are completely followed by the actual situation of the mobile station. It not only fits with auto start/stop genset function in multiple boot conditions, data measurement function, alarm protection function and etc, but also can control switches of 6 rectifiers at most and their parameters, at the same time it can monitor machine room temperature and voltage of battery packs to automatically start/stop genset and ensure normal working of base station.

HGM4020DC genset controller adopts micro-processor technology with precise parameters measuring, fixed value adjustment, time setting and set value adjusting functions and etc. All parameters can be configured from front panel or through programmable interface (USB or RS485 interface) via PC. It can be widely used in all types of automatic genset control system with compact structure, advanced circuits, simple connections and high reliability.

PERFORMANCE AND CHARACTERISTICS

132x64 LCD with backlit, selectable language interface (Chinese and English), push-button operation;

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

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

Two ways of RS485 communication port, one of which controls rectifiers and provide 5V power for them, and the other is used for remote control.

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 and shows mains 3-phase voltage/frequency parameters.

Mains  

Line voltage (Uab, Ubc, and Uca)

Phase voltage (Ua, Ub, and Uc)  

Frequency  Hz    

Phase sequence  

For Mains, controller has over and under voltage and loss of phase detection functions, and mains have rules can be selected.

Precisely collects parameters about Engine.

Oil Pressure (OP)      kPa/psi/bar

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

Machine room temperature can be collected, if temperature is too high, air conditioner in the machine will be started;

Battery pack voltage(48V) can be collected, if battery pack is under voltage, generator will be started to charge the battery;

6 start conditions can be grouped at random: mains abnormal signal, remote start signal, mains abnormal and temperature of machine room is high, mains abnormal and battery pack voltage is low, scheduled start, and cyclic start/stop;

4 selectable stop requirements and battery charging completed groups to complete stop after mains abnormal and battery voltage low;

5 relay output ports, and they are respectively 1 start output port, 1 fuel level output port, 3 programmable output ports;

6 digital input ports, in which input port 5 and input port 6 can be multiplexed as flexible sensor 1 and flexible sensor 2;

2 flexible sensors, which can be selected as temperature sensor, pressure sensor or fuel level sensor; flexible sensor 1 also can be configured as machine room temperature sensor;

Multiple temperature, pressure and fuel level sensors can be used directly and parameters can be users-defined;

Fits with switches to control rectifiers, and functions of setting output voltage and current;

Multiple crank disconnect conditions (speed sensor, generating and oil pressure) can be selected;

Access monitoring function, which can provide security for the machine room;

With emergency start function;

With scheduled not run function(monthly, weekly, daily, duration time can be set);

With inhibit to run setting, which shall inhibit genset to run in auto mode;

With cyclic start/stop function, controlling genset start/stop for how much time circularly;

With run log and real-time clock. Maximum 50 running records can be memorized (loop save);

With maintenance log. Maximum 20 records can be memorized (loop save);

With event log. Maximum 99 records can be memorized (loop save);

Parameter setting function: users can configure parameters and users-defined parameters will be stored in the internal FLASH to avoid parameters lost in case of power dropout. All parameters can be configured from front panel or through programmable interface (USB or RS485 interface) via PC;

Waterproof security level IP65 due to rubber seal installed between the controller enclosure and panel fascia;

With metal fixing clips;

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