2. Product overview
LXC7XXXseries of power plant automation controller for the automation and monitoring system of a single diesel generator sets, use
32-bit microprocessor technology, achieve generator sets automatic boot/shutdown, the precision measurement of various parameters,
alarm protection and three remote function. The controller uses a large-screen LCD (240*128LCD)graphics display, all the important
parameters can be displayed in page, save the page. At the same time can be displayed ChineseEnglish
and other languages, all parameters can be adjusted from the controller panel, can also be a PC through a USB interface tweaks and
RS485 or GPRS remote adjustment and monitoring. Its structure is compact, simple wiring, high reliability, automation control
systems are widely used in all types of generator sets and fire pumps.
3. Performance and characteristics
LXC7X10:Auto Stare Module, controls genset to start or stop automatically by remote start signal. LXC7X20:Auto Main Failure,
updates based on LXC7X10,especially for automatic system composed by generator and mains.
Main characteristics:
With ARM-based 32-bit CPU, highly integrated hardware, new reliability level;
240x128 LCD with backlight, multilingual interface(including English, Chinese or other languages) which can be chosen at the
site, making commissioning convenient for factory personnel;
All parameters can use the computer via USB, RS232, RS485 interface to connect and adjust, while the internal FLASH memory
within the controller in the system when power is not lost;
99% of the parameters can be set directly from the front panel for easy on-site commissioning;
RS485 communication port enabling remote control, remote measuring, remote communication via ModBus protocol (controller with
RS485 port only);
Equipped with SMS(Short Message Service)function. When genset is alarming, controller can send short messages via SMS
automatically to max.5 telephone numbers. besides, generator status can be controlled and checked using SMS. With advanced
networking capabilities, via GPRS mobile network and Internet connectivity, in any place where the network can be remotely
monitor;( Need to install the GPRS module: LXI680);
Equipped with CANBUS port and can communicate with J1939 genset. Not only can you monitoring frequently-used data(such as water
temperature, oil pressure, speed, fuel consumption and so on)of ECU machine, but also control starting up, shutdown, raising speed
and speed droop via CANBUS port (controller with CAN Bus port only);
Suitable for 3-phase 4-wire,3-phase 3wire,single phase 2-wire,and 2-phase 3-wire (120/240V)power and 50/60Hz Systems;
Collects and shows 3-phase voltage, current, power parameter and frequency of generator or mains;
For Mains, controller has over and under voltage, over and under frequency, loss of phase and phase sequence wrong detection
functions; For generator, controller has over and under voltage, over and under frequency, loss of phase, phase sequence wrong,
over and reverse power, over current functions;
3 fixed analog sensors(temperature, oil pressure and liquid level),more kinds of curves of temperature,oil pressure, fuel level
can be used directly and users can define the sensor curves by themselves;
2 configurable sensors can be set as sensor of temperature or fuel level; (Only LXC72X0 have this feature);
Protection: Automatic start/stop of the genset, ATS(Auto Transfer Switch)control with perfect fault indication and protection
function. When multiple warnings occur, the warning bar will rotate to display them, so that we can analyze the reasons;
All output ports are relay-out, And the main output 16A relay outputs and three passive relay output, more user-friendly;
Parameter setting: parameters can be modified and stored in internal FLASH memory and cannot be lost even in case of power
outage; most of them can be adjusted using front panel of the controller and all of them can be modified using PC via USB or RS485
ports.
With advanced networking capabilities, via GPRS mobile network and Internet connectivity, in any place where the network can be
remotely monitor;
A variety of starting conditions for success (speed sensor, oil pressure, power generation) to select, to facilitate the needs
of special occasions;
Wide power supply range (8 ~ 35) VDC, can adapt to different environment starting battery voltage, can under the low voltage of
starting motor moment continue to work for 3 seconds;
Fault history with 200, and can record the fault instant oil pressure ,water temperature, voltage, current and other important
parameters;
Equipped with real-time clock, scheduled start & stop generator(can be seas start gen-set once a day/week/month with load or
not),reach automatic maintenance;
Can be used on pumping units and as an indicating instrument (indicate and alarm are enable only, relay is inhibited );
3 set of maintenance functions, can be set for the machine maintenance cycle .Maintenance time to action can be set up(only
warning or alarm stop);
Waterproof security level IP55 due to rubber seal installed between the controller enclosure and panel fascia;
Improved LCD wear-resistance and scratch resistance due to hard screen acrylic;
Silicon panel and push buttons for better operation in high-temperature environment,and has a good waterproof performance;
Modular design, anti-flaming ABS plastic enclosure, plug gable connection terminals and embedded installation way, compact
structure with easy mounting.
Special industry application characteristics:
Leasing industry applications: management provides the perfect solution: leased out via PC remote Management of the unit, you
can monitor all operating parameters (oil pressure, water temperature, voltage, current, power, etc),you can always change the
configuration to protect the unit is not proper application, can record 200 detailed fault information, including: time to
failure, because ,when the voltage, current, power, oil pressure, water temperature and other key parameters, and ready to upload
to the monitoring machine. Another multi-level password management options to facilitate the lease management;
Fire pump industry applications: Close electrical parameter measurement function, use powerful Programmable input and output
ports and internal programmable logic to achieve automated pump control system. Instead of the conventional engine controller PLC
+ simple manner ,making the system more stable and reliable;
Air compressor industry applications: Close voltage measurements protection, according to the need to configure programmable
analog input, overload protection , with programmable digital inputs, complete startup control, temperature and pressure control,
protection parameter settings
