Error diagnosis

All faults at the inputs/outputs of the E3G080 are individually displayed at the AlgoPilot. For
each of the 4 outputs an LED is provided on the E3G080 for error diagnosis (see chapter 4.2).
Separate LEDs are not provided for the inputs, but a special mode enables the identification of
each faulty or deactivated input and output.
