Product overview A genset controller for diesel, gas, and gasoline engines that provides automatic start and stop, continuous parameter monitoring, and systematic fault checking. The unit includes a 3.5 inch LCD with a bilingual user interface in Chinese and English, and supports PC programming and remote monitoring through RS485, USB, and CAN ports using the MODBUS protocol. inputs and outputs allow flexible integration with a wide range of genset installations, including singlephase 2wire and threephase 4wire systems. Key benefits Automation and uptime: Automatic start and stop plus builtin fault checking reduce manual intervention and speed recovery from fault conditions. Faster troubleshooting: Faults and operating parameters are shown clearly on the 3.5 inch LCD as indicators and text, helping technicians diagnose issues quickly. Remote access and programming: RS485, USB, and CAN connectivity with MODBUS support enables PC programming and remote monitoring for centralized management. Flexible integration: Configurable I O and sensor ports support diverse control schemes and thirdparty devices without extra hardware. Clear local operation: Bilingual CN and EN display makes local operation and configuration straightforward for multilingual teams. Core features Auto start and stop for diesel, gas, and gasoline gensets Continuous parameter monitoring and automated fault checking 3.5 inch LCD screen with bilingual user interface (Chinese and English) Visual and textual display of faults and key parameters RS485, USB, and CAN ports with MODBUS protocol support for PC programming and remote monitoring I O: six relays (four programmable), five switch inputs, three sensor ports Voltage compatibility: supports singlephase 2wire (1P2W) and threephase 4wire (3P4W) configurations Performance and compatibility Designed for use with diesel, gas, and gasoline generator sets Programmable relays and multiple inputs enable control of engine start, stop, alarm outputs, and auxiliary functions MODBUScompatible communication facilitates integration into existing monitoring and control systems Typical applications Standby power systems for commercial buildings: Automatic operation and remote monitoring simplify management of backup generators and reduce response time during mains outages. Construction and rental gensets: Rugged controller features and programmable outputs allow rapid adaptation to varying site requirements and sensor setups. Remote installations and telecommunications sites: MODBUS over RS485 or CAN plus USB access lets technicians configure units locally and monitor genset health remotely. What it solves Reduces manual oversight by automating start, stop, and fault handling Shortens diagnostic time with clear onscreen fault messages and indicators Simplifies integration with control systems through standard MODBUS communication and configurable I O Supports multiple genset fuel types and common voltage wiring schemes for broad applicability Technical highlights (at a glance) Display: 3.5 inch LCD, bilingual CN and EN Communication: RS485, USB, CAN with MODBUS protocol I O: 6 relays total, 4 relays programmable; 5 switch inputs; 3 sensor ports Voltage support: 1P2W and 3P4W systems Functions: Auto start/stop, parameter monitoring, fault checking This controller is suitable for installers, service technicians, and facility managers who need reliable genset automation, straightforward local operation, and standard remote monitoring options.
