If bit OS1:2 is set (= optional trip), the "fault signals" (parameter identifier 748, 1 ,0) is registered in "group fault signal' of the main status word and a trip
is therefore generated for all "fault signals". If bit OS1:2 = 0 (= alarm), "fault signals" do not generate a trip, they are merely registered in the "group
warning signal" of the main status word. "Fault signals" can also be individually deactivated (by setting message numbers 1:101 to 1:106 to 0).
46)
If bit OS1:0 is set, an earth fault is registered in the "group fault signal" and a circuit-breaker trip is generated if an earth fault occurs. If bit OS1:0 = 0 (=
alarm), the occurrence of an earth fault is registered in the "group warning signal" of the main status word, and no trip is generated in this case.
