Model LXC701 Electronic Engine Controller Overview The LXC701 is an automatic start controller module for diesel generator sets. It supports manual start and stop from the front panel, automatic start via a remote start input, and continuous monitoring of key engine faults. Faults trigger automatic fuel relay disconnection and solenoid shutdown while panel LEDs show real time alarm status. The unit is compact, easy to install, and programmable via USB. Key benefits Reliable automatic start and stop for standby and prime power applications. Fast fault detection and clear LED indications for low oil pressure, water or cylinder temperature, emergency stop, overspeed, and start failure. Wide input voltage range adapts to different battery systems and vehicle installations. Programmable outputs and USB configuration let you match timing and thresholds to the specific genset. Small, embedded panel design fits standard cutouts for straightforward installation. Main features Supply voltage: 8 to 35 VDC compatibility with common starting batteries. Power input sensing: single phase AC 10 to 400 V at 50 or 60 Hz for speed and run detection. Protections and alarms for low oil pressure, water or cylinder temperature, overspeed, emergency stop, and start failure. Provides excitation output for generator charging circuit monitoring and excitation control. Idle speed control and poweroff function available. Speed sensing taken from generator frequency. Front panel LEDs display running and alarm states. Five relay outputs (four fixed: fuel output, start output, stop output, idle speed output; plus one programmable output). Relay outputs rated at 5 A, B plus supply type. Three digital input ports referenced to battery negative. USB interface for PC programming of delays, output definitions, and power thresholds. Builtin watchdog for reliable program execution. Modular design with ABS plastic enclosure and embedded installation profile for compact fit.

Programmable output can be assigned as common alarm, shutdown failure, preheat, nongeneration alarm, or other functions as required by the installation. Typical applications Residential backup gensets that require unattended automatic start on mains failure and clear fault indication for service technicians. Small commercial or light industrial generator sets used for emergency power, where programmable outputs and configurable protections are needed. Rental or mobile gensets where compact embedded controllers and flexible input voltage compatibility simplify installation and maintenance. What this controller delivers The LXC701 provides reliable automatic start and comprehensive engine protection in a compact package. It combines flexible programming, clear status indication, and standard relay interfaces to integrate with a wide range of diesel gensets and charging systems.
