Alarm status display interface
Alarm messages can be cleared remotely and manually. Manual clearing requires long-pressing the
host's "ESC" key for 2 seconds, remote clearing requires writing "1" to register 0x0079 to clear. If an
arc trip alarm occurs, it must be cleared manually or remotely. Restarting the host will still display the
alarm message.
DC arc fault alarm interface
After the DC arc sensor detects the occurrence of a fault arc, the alarm information interface of the
host is as shown below.
In the figure above: "02" means channel arc fault alarm, and "4" means that the fault arc alarm
channel is 4.
Fault alarm clear interface
The host sends an alarm when it detects a fault, and the user can choose to handle it locally or
remotely. By long-pressing the "ESC" key for about 5 seconds locally, the system jumps out of the
interface as shown below, indicating that the alarm status has been cleared; remote processing
needs to write "1" to 0x0079 to clear, and the interface shown below will be displayed after clearing
successfully.
