Reading the Codes:
In order to read the fault codes, a sequence of pauses and flashes can be seen on the LED mounted on the GP102
module. The codes are continuously displayed by the LED until the fault is cleared, the GP102 reset and no longer
detects the fault, or idle timeout becomes active.
The sequence is as follows:
1. Quarter second flashes followed by quarter second pauses indicate the first digit.
2. A 1.5 second pause.
3. Quarter second flashes followed by quarter second pauses indicate the second digit
4. A 4 second pause. Repeat steps 1-4
Since the GP102 only reports one error, only one code can be read from the LED per instance. If the error is cleared
and another error is present, it will then be presented.
