#1 LIXISE LXC6110N Series Generator Controller

Brand Introduction

Manufactured by Dongguan Tuancheng Automation under the LIXISE brand, the LXC6110N series addresses critical pain points in standby and prime power management: lack of real-time monitoring, complex manual operation requirements, and potential equipment damage from unmanaged fault conditions. Through intelligent control solutions combining automation, protection, and monitoring capabilities, LIXISE enables unattended operations while extending equipment service life through multi-layer protection logic.

Core Technology & Products

The LXC6110N product line encompasses six model variants—LXC6110N, LXC6120N, LXC6110NC, LXC6120NC, LXC6110N-CAN, and LXC6120N-CAN—providing scalable solutions from basic standby power to advanced communication-enabled installations.

Industrial-Grade Hardware Architecture: Panel-mount construction with 185×139mm cutout dimensions features isolated voltage and current sampling circuits, dry-contact relay outputs, and anti-interference design suited for high-EMI environments.
Comprehensive Parameter Monitoring: Real-time tracking of 3-phase voltage, current, frequency, engine RPM, oil pressure, coolant temperature, fuel level, and battery voltage through standardized CT/PT interfaces with isolated sampling.
Programmable Control Logic: Five digital inputs and six relay outputs (two fixed, four programmable) support custom configurations for remote start signals, fault inputs, and auxiliary control functions, enabling adaptation to complex operational requirements.
Multi-Protocol Communication: RS485 networking for mid-range models, CAN (J1939) interface for electronic engine integration, and USB-C connectivity for local configuration, data export, and firmware updates.
False Trip Mitigation Technology: Protection logic incorporates delay and hysteresis mechanisms—including 10V voltage hysteresis and 1V battery hysteresis—ensuring stable performance despite grid fluctuations or transient load variations.
Automated Lifecycle Management: Pre-programmed sequences for pre-heat, cranking, idle, warm-up, cool-down, and shutdown delays eliminate manual intervention requirements while improving operational consistency.

Key Features

The LXC6110N series distinguishes itself through several operational advantages:

Multi-Language LCD Interface: Large LCD display presents real-time data in Chinese, English, Spanish, or Russian, supporting global deployment scenarios.
Safety Run Delay: Mutes oil pressure and temperature alarms during startup periods to prevent nuisance tripping from transient conditions.
Scheduled Running Capability: Supports automated daily, weekly, or monthly start/stop cycles with or without load application—ideal for unattended telecommunications stations and emergency backup systems.
Three-Level Access Control: Password-protected Technician, Operator, and Factory access levels ensure secure configuration management and prevent unauthorized parameter changes.
Historical Fault Logging: Real-time clock (RTC) integration enables comprehensive fault history recording for post-incident diagnostics and maintenance planning.
Configurable Sensor Protection: Independent protection for coolant temperature, oil pressure, and fuel level with custom curve support and selectable open-circuit detection responses (warning or stop).
Three-Level Maintenance Reminders: Proactive warning and stop notifications based on accumulated runtime support scheduled maintenance programs.
