Product Overview:
HEM4300 Engine Controller is used for electronic engine control and data display to realize engine start/stop, speed control, data measurement, maintenance, alarm protection and "four remotes" (remote control, remote measurement, remote adjusting, remote communication). It adopts color LCD, which can display Chinese, English and other languages. The engine working parameters can be visually displayed on the screen. It is easy and reliable to run.

HEM4300 Engine Controller applies 32-bit micro-processor technology, which can realize functions of precise measurement for many parameters, set-point adjustment, timing and threshold setting etc. A majority of parameters can be adjusted from the control panel. All parameters can be adjusted and monitored on PC by RS485 or USB port. It can be widely used for various engineering machinery automation system like jumbo, crushing plant, tunnel tractor, air compressor, hydraulic power station, mining machinery with compact structure, simple wiring, high protection level and high reliability.

PERFORMANCE AND CHARACTERISTICS

2. 4.3-inch LCD display with resolution 480x272, adjustable backlight; Optional Chinese, English and other languages that is convenient for commissioning;

3. Silicon and hard screen acrylic front panel;

4. CANBUS port can connect ECU with J1939, which not only can monitor ECU common data (speed, water temperature, oil pressure, fuel consumption etc.), but also can realize engine start, stop, raise speed and drop speed;

5. With 6-way analog sensors, 3-way fixed resistance type, 3-way can be flexibly configured as resistance, current or voltage type;

6. Multiple temperature, pressure, level and vibration sensor curves can be used directly, and custom sensor curve is available;

7. Precisely collect all kinds of engine parameters including speed, water temperature, oil pressure, battery voltage, charger voltage, accumulated start time and start times. Complete protection functions that provides high water temperature, low oil pressure, over speed protection etc.;

8. Optional four speed control modes (key/potentiometer/throttle/key + throttle), which can meet different speed control demands of engineering machinery;

9. Various start/stop control methods can realize controller key start/stop, remote start/stop of input port, external key start/stop, which can meet various control demands of engineering machinery;

10. With idle/high speed transfer function and high speed value can be memorized, which is convenient for returning to last adjusted speed;

11. With 2-way PWM output, which can realize drive control of hydraulic proportional valve in engineering machinery;

12. With jumbo lever control logic that can realize manual lever control;
