HGM4020T 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 monitor machine room temperature and voltage of battery packs to realize dual power ATS function between mains and load or mains and air conditioner.
HGM4020T genset controller adopts micro-processor technology with precision parameters measuring, fixed value adjustment, time setting and set value adjusting and etc functions. 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.

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 cycle start/stop;
6 relay output ports, including 1 start output, 1 fuel output (programmable), 4 programmable outputs, in which programmable output port 4 shares the same port with input port 5 (can be set);
7 digital input ports, in which input port 6 and input port 7 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 its parameter can be user-defined;
Able to control 2 ATS;
Multiple crank disconnect conditions (speed sensor, gen frequency 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 flywheel tooth number automatic recognition function;
With event log and real-time clock. Maximum 99 event logs can be memorized(loop save).
Parameter setting function: users can configure parameters and user-defined parameters will be stored in the internal FLASH to avoid lose parameters in case of power dropout. All parameters can be configured from front panel or through programmable interface (USB or RS485 interface) via PC.;
Widely power supply range DC(8~35)V, suitable for different starting battery voltage environment.
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.
