Product Overview:

HSC941 Genset Controller integrates the digital, intelligent and network technology for automation and monitoring system of single unit, realizes the engine speed adjustment, the genset automatic start/stop, data measurement, alarm protection and “three remotes” functions. It applies LCD display, optional interface operation with Chinese and English. It is simple to operate and reliable to run.

HSC941 Genset Controller adopts microprocessor technique to achieve precision measurement of various parameters, value adjustment, timing and threshold setting, etc. All the parameters can be configured from front panel, or adjusted and monitored via PC by USB interface or RS485 interface. Because of the characteristics of compact structure, simple wiring and high reliability, it can be widely used in all types of genset automatic systems.


HSC941: used for automation of sigle unit by driving the stepping motor to adjust the throttle opening and then adjust the speed, to control genset automatic start/stop by remote signal;

Its main characteristics are as follows:

•LCD display with backlight, 132x64 size, simple Chinese and English display, push-button operation;
•Hard acrylic screen material with great wear-resisting and scratch-resisting performance, which are used to protect the screen;
•Silicone panel and push buttons, which can better adapt to extreme temperature environment;
•RS485 communication interface, which enables “three remotes” (remote control, remote measuring, remote communication) functions by MODBUS protocol;
•Suitable for 3P4W, 1P2W, 3P3W, 2P3W power supply 50Hz/60Hz systems;
•Collect and display generation 3-phase voltage, 3-phase current, frequency and power parameters;

•With ETS, idle speed control, preheating control, speed drop/raise control, all of them are relay outputs;
•Parameter setting: allow users to modify and set parameters, meanwhile they shall be stored in the internal FLASH and will not be lost even in case of power outage; all of them can be adjusted from the front panel of the controller and also can be modified on PC via USB or RS485 interface;
•Two fixed analog sensors (temperature, oil pressure);
•A flexible analog sensor can be set as temperature, pressure or level sensor, or set as Aux. input 6 and used in different occasions;
•A variety of temperature, pressure, fuel level sensor curves can be used directly, and can be defined by users;
•Multiple conditions of crank disconnect (gen frequency, speed, oil pressure) are optional;
•Wide power supply range: DC (8~35)V, adapting to different starting battery volts;
•Scheduled start/stop functions (once for monthly/weekly/daily and can be set with or without load);
•All parameters apply digital adjustment, getting rid of conventional analog modulation of normal potentiometer, improving the reliability and stability of the whole device;
•Rubber seal designed between the shell and the screen with protection level IP65;
•Metal fixing clips are used to fix the controller;
•Modular structure design, anti-flaming ABS enclosure, pluggable connection terminals, built-in mounting with compact structure and easy installation.
