7.2.1 Error codes
The LED-display Error codes are displayed in up to 3 sequences, this allows the Central Unit to
declare exactly which output that is related to the error (where applicable).
First sequence: Letters E:r is presented declaring an error code
Second sequence: Type of error code
Third sequence: Additional information (where applicable)
In example:
The example would imply that there is an short circuit on output 1A
(Repeated 3 times)
