Product Overview:
HGM7220N/HGM7220S series genset controller is used for single unit automation control, which can realize functions of single unit self-start, AMF, synchronization changeover, and cloud monitoring. It integrates digitalization, intelligence, with network technology. It applies LCD graph display, optional language interface (Chinese, English and etc.) with reliable and simple operating features.

HGM7220N/HGM7220S series genset controller adopts 32-bit micro-processor technology, making it possible to precisely measure most parameters, fixed value adjustment, time setting and limit value adjusting etc. Almost parameters can be configured from front panel of controller, and all parameters can be adjusted through PC software via USB/RS485 port and monitored through PC software via RS485. It can be widely used in all types of genset control automation system with compact structure, simple connections and high reliability.

HGM7220N/HGM7220S series genset controller has network communication module putted inside, so that the genset can be connected with Internet. After the controller logins the cloud servicer, genset data information (including GPS positioning, altitude etc.) shall be uploaded to the corresponding cloud servicer at real time, so that users can monitor and check genset running status and event logs by terminal device such as mobile APP (IOS or Android system), PC etc. and at the same time controller parameters can be configured on cloud servicer. Network communication module has SMS message function.



PERFORMANCE AND CHARACTERISTICS

HGM7220N: has mains&generating power monitoring function, which are used for mains/generating automatic changeover control. It is applicable for single unit automation system consisting of one mains circuit and one generating circuit. Mains disable can be performed by parameter setting and at this time it is used for single unit automation and genset self-start and self-stop can be controlled by remote start signal.

HGM7220S: is added mains synchronization changeover function on the basis of HGM7220N.

Main features are the followings:

132x64 LCD display with backlit, and selectable language interface (Chinese, English, and other languages) that can be chosen on site, which is convenient for debugging personnel commissioning.

RS485 communication interface, by which “4 remotes” (remote control, remote measuring, remote communication and remote adjusting) function can be realized through MODBUS protocol.

Suitable for 3-phase 4-wire, 3-phase 3-wire, single phase 2-wire, and 2-phase 3-wire power systems with voltage 120/240V and frequency 50/60Hz, and HGM7220N can also be used in 400Hz system (please order alone.).

Protection control function: diesel genset automatic start/stop, ATS (Auto Transfer Switch) control with perfect fault indication and protection functions.

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

Parameter setting function: parameters can be modified and set by users and they won’t get lost in case of power outage. Most parameters can be modified on the front panel. All parameters can be adjusted on PC via USB or RS485, or modified on cloud servicer.

Multiple temperature, pressure, fuel level sensor curves can be used directly and sensor curves can also be users-defined. Pressure and auxiliary 1 can connect with resistance, voltage or current sensors.

Multiple crank disconnection conditions (speed, oil pressure, generator frequency) are optional.

Wide power supply range DC(8~35)V, which is suitable for different starting battery voltage environment.

Event log, real-time clock, scheduled start & stop (genset start once a day/week/month and load or not can be set.) functions and two gensets circular start function.

Data recording function for mains voltage, mains frequency, generator voltage, generator frequency, current, temperature, oil pressure, fuel level, speed and etc. one minute before shutdown fault and maximum records are 5.

Applicable for pumping units as indicating instrument. (only for indication and alarm, none actions for relays.)

Maintenance function: maintenance time or maintenance time due action can be set (only warning/trip shutdown/alarm shutdown).

Circular start of two gensets via CAN interface: master running time and backup running time can be set.

Connecting with cloud servicer via 4G wireless network is available.

SMS function: When an alarm occurs, the controller can automatically issue alarm information to 5 mobiles set previously and genset control and genset status check both can be realized by messages.

GPS positioning function: catching genset position information to realize genset positioning.

Applying network data communication protocol with JSON format: uploading data if there is data change, and meanwhile compression algorithm is employed to extremely reduce network flow. When an alarm occurs, it can upload data to the servicer immediately.

Waterproof security level IP65 due to rubber gasket installed between the controller enclosure and display screen.

Metal fixing clips are used.

Modular design, pluggable connection terminals and embedded installation way, and compact structure with easy mounting.
