1OVERVIEW
HMU15 genset controller is suitable for remote monitoring single/multi HGM9510 genset
controllers, which can realize auto start/stop genset, data measurement, alarms display and “Three
Remote” functions (remote control, remote measurement and remote communication). It fits with
LCD display, multi-level operation authorities and touch screen, so as to make this module reliable
and easy to use.
With high-end microprocessor design, HMU15 controller can communicate with HGM9510
genset controller via RS485. Then parameters of genset can be read directly through communication
ports and displayed on the HMU15 screen.
2PERFORMANCE AND CHARACTERISTICS
─One or up to six HGM9510 genset controllers can be monitored remotely;
─High-end ARM microprocessor as the core, LCD with backlit, HMI display and touch screen
operation;
─Real-time display genset parameters and alarms information that detected by the
HGM9510 controller;
─HMU15 is able to control detailed parameters and keys operation of HGM9510 genset
controller;
─Operation authorities can be configured to prevent misoperation from non-professionals
resulting in abnormal operation of gensets and unnecessary accidents;
─High accuracy time display, and “engineer”or “technician”level authority can set current
time of system;
─Modular design, pluggable wiring terminals, built-in mounting, compact structure with easy
installation.

Fig.5 –Wiring Diagram
NOTE: Communication line need use shielded line, if the distance is close, 1#GND and 2#GND not need to be
connected to the shielded layer.
NOTE: Please unplug HMU15 power cable before wiring to avoid electric shock or accident.
NOTE: HMU15 communicates with HGM9510 via RS485 communication port, using the matched communication
line, one end (DB9) connects with HMU15, and the other end, which has 6 lines (two communication ports). 1#485+
and 1#485- are one communication port, which can connect with three HGM9510 controllers (communication
address can be set as 1, 3, 5); 2#485+ and 2#485- are the other communcation port, which can connect with three
HGM9510 controllers (communication address can be set as 2, 4, 6).
