Feature 1100% brand new and high quality. 2 Made of high-quality materials, durable. 3 The HGM1790N generator set controller is suitable for the automation and monitoring control of a single unit (it can also be used for the pulling unit). 4 It can be started or stopped manually, or it can be started and stopped by remote start/stop signals. 5 The HGM1790N controller can supervise and protect the operation of the generator set by collecting and analyzing generator set data (such as generation voltage, current, water temperature, oil pressure, etc.), and the graphic LCD monitor on the front panel displays fault conditions and provides effective alarm signals for Carry out early maintenance. 6 In addition, the parameter threshold and delay value can be adjusted through the front panel or USB port (communication with PC software). 7 Graphic LCD display (with backlight), LED indicator, touch button operation. 8 The hard screen acrylic material is used to protect the screen. 9 Silicone panels and buttons are used to improve high and low temperature adaptability. 10 Power range: DC (8~35)V, compatible with 12V or 24V starter battery. 11 Measure and display generator single-phase voltage, current, frequency, power and load percentage parameters. 12 Generator voltage V Generator frequency Hz. 13 Generator power kW Generator current A. 14 Load percentage. 15 Accurate measurement and display of power of the generator. 16 Oil pressure kPa temperature ºC. 17 Fuel level% total operating time H (up to 199999 hours). 18 Battery voltage V engine velocity RPM. 19 Cumulative start time (up to 199999 times, displayed on PC). 20 With generator set fault protection and display functions. 21 3 working modes: manual, automatic, stop. 22 Compatible with multiple temperature, pressure and fuel level sensors, which can be defined by the user and used directly; temperature sensors and pressure sensors can be used in parallel with the annunciator to provide analog quantities and improve the protection level at the same time. 23 A variety of crank disconnect conditions are available (engine velocity sensor, oil pressure, generator frequency). 24 1 configurable input port, which can be set as digital input or liquid level sensor. 25 4 fixed relay outputs (fuel relay, start relay, stop relay and idle velocity relay). 26 1 configurable output port, which can be set as general alarm output, non-stop output, preheat output or idle velocity control output. 27 Users can set and modify parameters and save them in the internal flash memory, which means they will not be lost in the event of a power failure. 28 Most of the parameters of the controller can be modified using the front panel, and all parameters can be adjusted through the PC software through the B-type USB port. 29 Digital adjustment of all parameters-instead of analog adjustment using conventional potentiometers-therefore, has higher reliability and stability. 30 Modular design, self-extinguishing ABS plastic shell and embedded installation; small size, compact structure, easy to install.DisplayLCD (with backlight) Operation panel rubber English language Digital input: 1 Relay output: 5 Analog input: 1 AC system: 1P2W AC voltage: (15~360)V(ph-N) Alternator frequency: 50/60Hz KW/ampere detection and display Programmable interface: USB DC power supply: DC(8-35)V Box size: 95*86*46.5mm Panel opening: 78*66mm Working temperature: (-30~+80)degree CelsiusPackage List1*HGM1790N Generator set controller 1*Instruction
