Product Overview:
HGM4100LT Power Station Automatic Controller is designed especially for adapting extremely low/high temperature (-40~+70)℃, which integrates digitization, intelligentization and network technology, and are used for single genset automation and monitoring control system, in order to achieve automatic start/stop, data measurement, alarm protection etc. functions. It applies LCD display, optional interface operation with eight languages (Chinese, English, Spanish, Russian, Turkish, French, Portugal, and Polish). It is simple to operate and reliable to work.

HGM4100LT Power Station Automatic Controller employs micro-processor technology, which makes these functions come true, including precise parameter measuring, fixed value adjustment, time setting and integer limit value adjusting etc. All parameters can be configured from the front panel. They can also be adjusted and monitored through programmable interfaces (USB or RS485 interface) via PC. Because of the characteristics of compact structure, simple wiring connection and high reliability, it can be widely used in all types of automatic genset control system.


HGM4100LT: it is used for single unit automation and genset auto Start/Stop control by remote start signals.

Main characteristics

LCD display with backlight, 132x64 size, and eight language display (Chinese, English, Spanish, Russian, Turkish, French, Portugal, and Polish), 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 pushbuttons which can better adapt extreme temperature environment;

RS485 communication interface, which enables “Three remote functions” (remote control, remote measuring and remote communication) by MODBUS protocol;

CANBUS port, which can connect with J1939-equipped electronic injection engine. Not only can it monitor frequently-used data (such as water temperature, oil pressure, speed, fuel consumption and so on) of ECU machine, but also control start-up, shutdown , speed raising and speed dropping etc. (the controller with CANBUS interface is needed);

Suitable for 3-phase 4-wire, 3-phase 3-wire, single phase 2-wire, and 2-phase 3-wire systems with voltage 120/240V and frequency 50/60Hz;

Collecting and displaying 3-phase voltage, 3-phase current, frequency, and power parameters;

Control and protection function: automatic start/stop of the diesel genset, ATS (Auto Transfer Switch) control and perfect fault indication and protection functions;

ETS (energize to stop), idling speed control, pre-heating control and speed rise/drop control functions, which are all relay outputs;

Parameter setting function: it allows users to change and set parameters and meanwhile they shall be stored in the internal FLASH. They shall 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 port;

Two multiplex input port 4 and 5; Input port 4 can be configured as switch input port or fuel level sensor; input port 5 can be set as switch input port or programmable sensor. It can be flexibly applied on different occasions.

Multiple temperature, pressure, oil level sensors can be used directly and their parameters can be self-defined;

One programmable sensor; it can be configured as temperature, pressure or liquid level sensor, which achieves the detection for double temperature, double pressure or double liquid level;

Optional crank disconnection conditions (speed sensor, oil pressure, generating);

Emergency start function;

Automatic recognition function for flywheel tooth number;

Wide power supply range (8~35)VDC, which is suitable for different starting battery voltage environment;

All parameters apply digital adjustment, getting rid of conventional analog modulation of normal potentiometer, improving the reliability and stability of the whole device;

Maintenance function; maintenance types can choose date or running time, maintenance actions can be configurable (reactive, warning, or alarm shutdown);

Event log, real-time clock, and scheduled start & stop function (start once each day/week/month and loading or not can be set); Maximum event logs are 99 items;

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 plastic enclosure, pluggable connection terminals and embedded installation way with compact structure and easy mounting.
