Product Overview:
HEM4000 ENGINE CONTROLLER is used for controlling engine to realize engine auto start/stop, data measure, alarm protection and “three remotes” (remote control, remote measuring and remote communication) functions. It provides speed regulation function, not only with relay speed-adjusting output but also with GOV interface, which can control all kinds of non-EFI engines’ speed.

HEM4000 ENGINE CONTROLLER adopts large liquid crystal display (LCD) and selectable Chinese and English interface with easy and reliable operation. Users can read engine working parameters from the LCD directly.

HEM4000 ENGINE CONTROLLER uses 32 bits ARM micro-processor technology with the functions of precise parameters measuring, fixed value adjustment, time setting and threshold adjusting etc. The majority of parameters can be set on the front panel and all the parameters can be set and monitored via USB port or RS485 port by using PC. With compact structure, simple connections and high reliability, it can be widely used in a number of genset control systems, which include water pump system, bacon system, air compressor, engineering and machinery system and so on.

PERFORMANCE AND CHARACTERISTICS

132x64 LCD with backlight, multilingual interface (including English and Chinese languages) and easy operating interface;

Hard acrylic screen protection with improved wear-resistance and scratch resistance;

Silicon panel and pushbuttons for better operation in high and low temperature environment;

RS485 communication port to realize remote controlling, remote measuring, remote communicating via ModBus protocol;

6 channels of analog sensors, 3 channels of fixed resistor sensors, and 3 channels of flexible sensors, which can be configured as resistor/current/ voltage type sensors;

Multiple temperature, pressure and level sensor curves can be used and user-defined directly;

Precisely collecting various engine parameters provides complete protection functions, such as engine high water temperature/ low oil pressure, over speed and under speed protection;

With mechanical speed regulation function and GOV speed adjustment function, it can control engine speed up and down manually;

High speed/idling speed switchover function;

All outputs are relay outputs;

With the function of parameter setting, it allows users to change and set the parameters and at the same time they will be stored in the internal FLASH memorizer and cannot be lost in case of power outage;

Alternate crank disconnect conditions (engine speed, oil pressure);

Engine speed can be obtained by speed sensor or W/L charging generator;

Wide power supply range DC(8~35)V, which is suitable to different start battery voltage environment;

Event log, real-time clock, scheduled start & stop functions (start one time once a day/week/month);

Heater, cooler and fuel pump control functions;

Maintenance function. Actions (warning or shutdown) can be set when maintenance time due;

All parameters adopts digital adjustment instead of conventional analog modulation with a potentiometer, which improves the reliability and stability;

Waterproof security level IP65 of the front panel due to the rubber seal in the case design;

Metal fixing clips enable perfect performance in high temperature environment;

Modular design, flame retardant ABS case, pluggable connecting terminals and embedded installation way; Structure is compact and the installation is very easy.
