Electronic Engine Control
HEM4100 High Quanlity For Diesel Generator Make In ChinaProduct Description
The HEM4100 engine controller is used to control the engine and realize the automatic start and stop of the engine, data measurement, alarm protection and "three remote" functions. The controller has a speed regulation function. In addition to the relay speed regulation output, it also has a CANBUS (SAE J1939) interface, which can control various EFI or non-EFI engines.
The HEM4100 engine controller uses a large-screen liquid crystal () display, which can display Chinese and English, and the engine working parameters can be intuitively displayed on the screen. The operation is simple and the operation is reliable.
The HEM4100 engine controller uses 32-bit ARM microprocessor technology, which realizes the precise measurement, fixed value adjustment, , and threshold value adjustment of various parameters. Most parameters can be adjusted from the front panel of the controller, and all parameters can be used by PC Adjustment and monitoring through RS485 or USB interface. Its compact structure, simple wiring and high reliability can be widely used in engine control systems such as water pumps, light towers, air compressors and construction machinery.
Performance characteristics
Its main features are as follows:
Liquid crystal display is 132x64, with backlight, Chinese and English optional, simple interface operation;
The screen protection adopts hard screen acrylic material, which has good wear resistance and scratch resistance;
The use of silicone panels and buttons, strong ability to adapt to high and low temperature environment;
With RS485 communication interface, using the MODBUS protocol can realize the "three remote" function;
With CANBUS interface, you can connect the EFI machine with J1939, not only can monitor the common data of the EFI machine (such as water temperature, oil pressure, speed, fuel consumption, etc.), you can also control the start, stop, speed up and Speed reduction, etc .;
6 analog sensors, 3 fixed resistance types, 3 channels can be flexibly configured into resistance type, current type and voltage type;
A variety of temperature, pressure, liquid level sensor curves can be used directly, and the sensor curve can be ;
Precise collection of various parameters of the engine, with various protections such as high engine water temperature, low oil pressure, overspeed and underspeed, etc.
With speed regulation function, you can manually control the engine speed up and down;
With idling / high speed switching function;
All output ports are relay outputs;
With parameter setting function, allowing users to change and set their parameters, while memorizing in internal FLASH memory, it will not be lost when the system is powered off
The starting conditions (speed, oil pressure) can be selected;
Speed can be obtained by speed sensor or charging generator W / L;
The power supply range is wide (8 ~ 35) V, which can adapt to different starting battery voltage environments;
With historical records, real-time clock, switch machine (monthly / weekly / once every day) function;
With heater, cooler and fuel pump control functions;
With maintenance function, the maintenance time can be set to action;
All parameters are adjusted digitally, abandoning the analog adjustment method of conventional potentiometers, and improving the reliability and stability of the whole machine;
The shell is designed with rubber sealing ring, and the front panel waterproof performance can IP65;
Fixed controller card adopts metal card, excellent performance in high temperature environment;
Modular structure design, flame retardant ABS shell, pluggable terminal block, embedded installation, compact structure and easy installation.
