Pr.02-13 (Multi-function output 3 R1A (Relay 3)) is set to 35 Fault output option 1 (Pr.06-22).
Pr.02-14 (Multi-function output 4 R2A (Realy4)) is set to 36 Fault output option 2 (Pr.06-23).
Pr.02-15 (Multi-function output 5 (MO1)) is set to 37 Fault output option 3 (Pr.06-24).
Pr.02-16 (Multi-function output 6 (MO2)) is set to 38 Fault output option 4 (Pr.06-25).
Also assume that external fault outputs with the following signal: R1A = 1, R2A = 1, MO1 = 0 and MO2 = 1.
The corresponding Bit 3–0 is 1011.
