* Series power station automation controllers are used in the automation and monitoring system of a single diesel generator set to realize automatic start/stop, data measurement, alarm protection and "three remote" functions of the generator set. The controller adopts a liquid crystal (LCD) graphic display, which can display Chinese, English and other languages, with simple operation and reliable operation.
The *series power station automation controller adopts 32-bit microprocessor technology, which realizes the functions of precise measurement, fixed value adjustment, timing and threshold setting of various parameters. Most of the parameters can be adjusted from the front panel of the controller, and all parameters can be used The PC can be adjusted through the USB interface, and the PC can be adjusted and monitored through the RS485 interface. It has compact structure, simple wiring and high reliability, and can be widely used in various types of generator set automation systems.
Features
*Using 32-bit ARM single-chip microcomputer, the hardware integration is high, and the reliability is further improved;
*The liquid crystal display LCD is 132x64, with backlight, optional interface operation in Chinese, English and other languages, and can be selected on site, which is convenient for factory debugging personnel to test the machine;
*The screen protection is made of hard screen acrylic material, which has better wear resistance and scratch resistance;
* Using silicone panel and buttons, the ability to adapt to the high and low temperature of the environment is stronger;
* With RS485 communication interface, the "three remote" function can be realized by using MODBUS protocol; (a controller with RS485 interface is required);
* With SMS function, when the generator set has an alarm, it can automatically send alarm information to the set 5 phone numbers, and can also control the generator set and check the status of the generator set through text messages; (a controller with a GSM interface is required);
* With CAN BUS interface, it can be connected to EFI with J1939, not only can monitor the common data of EFI (such as water temperature, oil pressure, speed, fuel consumption, etc.) speed and deceleration, etc. (a controller with CAN BUS interface is required);
*Suitable for three-phase four-wire, three-phase three-wire, single-phase two-wire, two-phase three-wire (120/240V) power supply 50/60Hz system;
* Collect and display mains/generating three-phase voltage, three-phase current, frequency, power parameters;
* Mains has the functions of overvoltage, undervoltage, overfrequency, underfrequency, phase loss, and reverse phase sequence. Power generation has functions of overvoltage, undervoltage, overfrequency, underfrequency, overcurrent, overpower, reverse power, phase loss, reverse phase sequence function;
*Three fixed analog sensors (temperature, oil pressure, liquid level);
*Two programmable analog sensors can be set as temperature or pressure or liquid level sensors (only HGM72X0 has this function);
*Precise collection of various parameters of the engine:
Temperature WT °C/ °F displayed simultaneously
Oil pressure OP kPa/Psi/Bar displayed at the same time
Fuel level FL unit: %
Speed SPD unit: RPM
Battery voltage VB unit: V
Charger voltage VD unit: V
Timer HC can accumulate 65535 hours
Cumulative boot times Up to 65535 times
*Control and protection function: realize the functions of automatic start/stop of diesel generator sets, closing and opening (ATS switching) and perfect fault display protection;
*All outputs are relay outputs;
*Parameter setting function: allows users to change and set their parameters, and at the same time, it is stored in the internal FLASH memory and will not be lost when the system is powered off. Most of the parameters can be adjusted from the front panel of the controller, all parameters can be adjusted through the USB interface using a PC, and can be adjusted through the RS485 interface using a PC;
*A variety of temperature, pressure, oil level sensor curves can be used directly, and the sensor curves can be customized;
*Various start success conditions (speed sensor, oil pressure, power generation) can be selected;
* The power supply range is wide (8~35)VDC, which can adapt to different starting battery voltage environment;
*HGM7200 series controllers have the functions of historical record, real-time clock, and timing switch (on once a month/week/day and can be set to load or not);
*It can be used for water pump unit, and can also be used as indicating instrument (only indicating, alarming, relay has no action);
* With maintenance function, the maintenance time can be set to the action (only warning or alarm shutdown);
*All parameters are digitally adjusted, abandoning the analog adjustment method of conventional potentiometers, and improving the reliability and stability of the whole machine;
*A rubber sealing ring is designed between the shell and the control panel, and the waterproof performance can reach IP55;
*The clamps for fixing the controller are metal clamps, which have better performance in high temperature environment;
* Modular structure design, flame retardant ABS shell, pluggable terminals, embedded installation, compact structure, easy installation.
