FuncEnab : If disable the function is disactivated

BI : Operation controlled by Blocking Digital Input

Trg : Function operation triggers the oscillographic wave form capture
(see § 2.2.3.12)

tIoH : Trip time delay
2.2.5.8 - BF (F51BF) - Breaker Failure
FuncEnab  Enable [Disable / Enable]
Options

TrR Relay1 Relay1 – Relay2 – Relay3 – Relay4

TrR
: Output relay programmed for trip command to the Circuit Breaker

tBF : Trip time delay

Operation: If after the time “tBF” from pick-up of the programmed relay “TrR” the current
measured still exceeds 5%In, the output relay associated to the “BF” function is operated
(relay another than TrR).
2.2.5.9 - RTD - Remote Trip
Remote trip is controlled via the Digital Input D2.
