OVERVIEW

HRC12 Bluetooth Module is a transition module of data communication between mobile and genset. It is connected with genset controller via RS485. By mobile APP genset information can be obtained and genset start/stop can be controlled.

PERFORMANCE AND CHARACTERISTICS

” Mobile bluetooth can monitor genset status from far away, and communication distance is longer than 50m;
” From mobile genset controller power can be controlled or genset controller can be awaken up;
” Wide supply range DC (8~35)V, which can directly use the start battery self-contained in the engine;
” Module panel has power and communication status indicator, so module working status is very clear;
” Standard 35mm rail installation and M4 fixing installation is applied;
” Modular structure design, flame retardant ABS enclosure, light weight, compact structure with easy installation.

APP CONNECTION ILLUSTRATION

(1) Download HRC12 Bluetooth Communication Module APP from SmartGen and install it in the mobile phone; open mobile APP interface as Fig. 5 Saved Device Interface, and the list shows the saved device. Click the connected device (it will jump to the connected interface if the connection is successful. If connection is overtime, or device is far to connect, it will display on the current page.). Press longer to delect (Delect Dialog Box will appear.).

(2) Click Scan Bluetooth page, pull down and refresh, as Fig. 6 Scan Bluetooth Interface.
Display contents:

Bluetooth Name
Saved Name (unsaved one is New Device.)
Bluetooth Address
Signal Intensity

Click CONNECT and jump to Connected Devices page (HRC12 Bluetooth Name – SmartGen-HRC12).

(3) Connected Devices page is as Fig. 7 Connected Devices Interface; after successful communication,

it will read out software and hardware version numbers.
Rename – Change current saved device name;
Module Address – Lower computer module address;
Alarm information occurs in the middle – When genset is running normally, Unit Run displays green, otherwise it is red; when Mains fault occurs, Mains Failure displays red.
Disconnected – Disconnect Connection (only supports one to one connection; for changing Bluetooth device, it needs to disconnect current device and then to connect with others); enter Connected Devices page, it needs to input lower computer password for the first time to operate on the lower computer.
Power On – Controller connected with WAKE UP terminal is awaken up;
Power Off – Controller connected with WAKE UP terminal is low power consumption mode;

WAKE UP OUTPUT ILLUSTRATION

When click POWER ON button in Fig. 7 Connected Devices Interface, controller connected with Bluetooth Module WAKE UP terminal goes from low power consumption to normal working mode.
