Legend
------

OK1
  Fast response

OK2
  xPulses: max external delay 300us, if > 300us - may get external failure error

OK3
  cannot safely handle disconnection by itself - should be combined with redundant signal of other type

OK4
  OK2+OK3, ie, max external delay 300us and cannot safely handle disconnection by itself

OK5
  As OK 2) but will be developed in next step, not included in first certification.

N
  Not allowed

.. note::
   The table shows compatibility between different pulse types and system states.
   Each cell indicates the compatibility level using the codes defined in the legend above.
