Troubleshooting
Dual Wall Pro Earth
Troubleshoot by LED behaviour or LCD display
If fault occurs, users can check the fault information on the LCD or by the number of blinks
of the LED indicator light. Each fault is indicated with a sequence of different numbers of
LCD blinking. A pause of 3 seconds between each sequence indicates the beginning or end
of a sequence. If multiple faults happen at the same time, each sequence of blinking shows
in chronological order at an interval of 3 seconds.
Please see the table below for detailed information:
