Error codes
The Central Unit will indicate detected errors via the double 7-segment LED display.
If the Central Unit detects an error it will be indicated by the LED STATUS flashing
red whilst the the double 7-segment LED display indicates the error code with the
digits “Er” followed by four digits in two blocks with the corresponding error code.
Example on error code sequence:
“Er” -> “15” ->”1A” -> ““Er” -> “15” ->”1A” ->“Er” -> “15” ->”1A” ->
The error code sequence will repeat itself three times if the error is considered a soft
error and reboot to standby mode, if the error is considered a hard error the error
code sequence will be continued until supply power is disconnected.
