General flow diagram [10]The causes of the failures are coded as C1, C2, C3, ...., Cn and controls and interventions that mustbe made in accordance to these causes are coded C1A1, C1A2, ...., C1An. This coding system is shownand exemplified with an alarming condition that is given below. F is the alarm condition in the systemthat is explained before and C refers to the reason of the alarm and A is the order of the action that mustbe made to resolve the alarming condition.64
