Indicator Light Description
|
指示灯 |
描述 |
|
1. Power indicator light |
The power supply indicator (green) flashes when the module is connected to power. If the light goes off, the module is not working properly and the power supply must be disconnected. |
|
2.Communication indicator light |
The indicator (green) flashes when downlinking data (the computer sends data to instrument), and it goes off when data is sent; when the green indicator is on without data transmission, it indicates that the module is not working properly. The indicator (green) flashes when uplinking data (instrument sends back data to the computer), and it goes off when data is sent; when the green indicator is on without returning data, it indicates that the instrument is not working properly or line failure. |
| 3. Overload Indicator |
When MBus is short-circuit or overload, the indicator (red) will be on constantly and the module will enter the protection state. Disconnect the loads and the module will recover automatically. |
1. Connect module DC+ and DC- to positive and negative power supply respectively, the power indicator (green) will flash; then connect the A+ and B- of the external 485 with the 485+ and 485- of the module.
2. Connect F1 and F2 of HBS converter to F1 and F2 of Daikin VRV communication board.
Troubleshooting Common Issues:

Issue |
Troubleshooting Methods |
|
1. The power indicator does not light up after connecting the power supply. |
Check if the power input connection is secure. |
|
2.Green communication indicator does not flash when downlinking data. |
Check if the USB port is selected correctly and if the driver is installed correctly. |
|
3. Green communication indicator is constantly on or flashes when there is no data transmission. |
The module has malfunctioned. Please contact the manufacturer for repair. |
