LXC6620 Series Genset Automation Controller Description

Product Overview

LXC6620 series power plant automation controller is designed for automatic monitoring systems of single diesel generator sets. Adopting high-performance 32-bit ARM microprocessor technology with highly integrated hardware, it realizes automatic start/stop of gensets, high-precision measurement of all operating parameters, complete alarm protection and full three-remote functions (remote measuring, remote signaling, remote control).

Equipped with a 240*128 backlit graphic LCD screen, all core operating parameters can be displayed and saved on a single page without frequent page switching. It supports multi-language interface including Chinese, English, Russian and Spanish. 99% of parameters can be adjusted directly via front panel buttons; users can also fine-tune parameters by PC through plug-and-play USB port, or implement remote monitoring & adjustment via RS485 or external GPRS module. Featuring compact modular structure, simple wiring and outstanding stability, this automation controller is widely applied to various generator sets and fire water pump units.

Core Standard Functions

1. Average Load Rate Monitoring Real-time load rate calculation tracks genset operating status continuously to effectively avoid long-term overload operation and extend unit service life.
2. Customizable Startup Interface Supports personalized boot screen setting; users can upload company logo, enterprise name, contact information and brand slogans for brand display.
3. Installment Password Authority Management Built-in dual-level identity password system to realize installment lock and standardized management of generator equipment.
4. Multi-cycle Maintenance Reminder System Automatically accumulate total running hours, with 3 independent maintenance cycles configurable. It can trigger warning or emergency shutdown reminders when service period expires.
5. 240*128 Large Single-page LCD Display All key operating data displayed on one screen, eliminating repeated page switching for convenient on-site inspection.
6. Global Multi-language Selection Built-in multi-language packages: Chinese, English, Russian and Spanish to match global operators.
7. Plug-and-Play USB Debugging Port One-click connection with PC for parameter calibration, program upgrade and fault log export, easy for field debugging.
8. 200 Historical Fault Records Store 200 fault logs, capturing complete voltage, current, oil pressure, water temperature and power parameters at the moment of 25 fault events, supporting efficient troubleshooting and maintenance analysis.
9. Real-time Clock & Programmable Timed Test Run Support 2 groups of scheduled auto exercise runs to keep standby gensets in optimal working condition.
10. Comprehensive Mains Abnormality Alarm Detection Real-time monitoring & warning for mains overvoltage, undervoltage, overfrequency, underfrequency, phase loss and reversed phase sequence.
11. Two-level User Identity Permission Management Separate operator and administrator access authority to prevent unauthorized parameter modification and misoperation.

Professional Hardware & Communication Performance

• Adopts 32-bit ARM single-chip microcomputer, highly integrated hardware greatly improves overall reliability and anti-interference capacity.
• All parameters are stored in built-in FLASH & EEPROM memory, no data loss after power cut-off.
• Realize three-remote functions based on Modbus communication protocol; USB & RS232 are standard interfaces, RS485 is optional.
• Built-in SMS alarm function: automatically send fault alert messages to up to 5 preset mobile numbers; users can remotely query unit status or trigger start/stop via text messages.
• Advanced IoT remote monitoring: connect with internet via external LXI680 GPRS module, realize cross-regional remote supervision anywhere with network coverage; optional WIFI communication transmits real-time data to cloud platform for intelligent fault analysis.
• Compatible with 50/60Hz power systems: 3P4W, 3P3W, 1P2W, 2P3W (120/240V).
• Collect and display full electrical data: mains/generator 3-phase voltage, 3-phase current, phase sequence, frequency, active/reactive power, power factor, cumulative electric energy and all engine sensor data.
• Complete dual protection logic: Mains only trigger warning for overvoltage, undervoltage, overfrequency, underfrequency, phase loss & reversed phase sequence; generator will trigger warning and emergency shutdown for overvoltage, undervoltage, overfrequency, underfrequency, overcurrent, phase loss and reversed phase sequence.
• Reserved 3 standard analog sensor ports for coolant temperature, oil pressure and liquid level; multiple pre-stored sensor characteristic curves are selectable, and users can customize sensor curves to match various engine brands.
• Full automatic control of diesel & gas gensets: auto start/stop, ATS mains-generator breaker closing & opening, circular multi-alarm scrolling display for quick fault sorting.
• All output ports are relay-driven; main control outputs adopt 16A high-current relays, plus 3 passive relay outputs to meet complex engineering matching demands.
• Multiple startup trigger conditions optional: speed sensor, oil pressure, generator voltage and charging voltage, adapting to all special application scenarios.
• Wide DC power supply range of 8~35V, stable operation for 3 seconds under instantaneous ultra-low cranking voltage during engine startup.
• Dual usage mode: work as automatic control unit for fire pump sets, or pure power indicating instrument with alarm only (relay output locked inactive).

Mechanical & Environmental Optimization Design

• IP55 waterproof grade: rubber sealing ring embedded between panel and housing for dust & water resistance.
• Hard acrylic screen protector, wear-resistant and scratch-proof for long-term outdoor use.
• Silicone keypad panel with outstanding high & low temperature tolerance and waterproof performance.
• Modular flame-retardant ABS housing, pluggable wiring terminals, embedded installation design, compact size and simple wiring for fast assembly.
