the Major Alarm OR the Minor Alarm OR both is true.

Example 2 - Inverse Overcurrent Logic Diagram

Figure 201 illustrates a typical logic diagram of two inverse overcurrent elements set up to trip outputs
and trigger fault reports. The 51-1 function is blocked when IN1 is true. The 51-1 function is blocked when
IN2 is true. OUT1 is true when either the 51-1 or 51-2 is in a trip condition. OUT2 is true when either the
51-1 or 51-2 is in a pickup condition. The fault trigger logic block ensures that faults are recorded.
