3.8 - BF (F51BF) - Breaker Failure
FuncEnab → Enable [Disable / Enable]
Options → TrR Relay1 Relay1 – Relay2 – Relay3 – Relay4
TripLev → No Param No Parameters
Timers → tBF 0.2 s (0.05  0.75) step 0.01 s
Description of variables
FuncEnab : If disable the function is disactivated
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).
3.9 - I.R.F. - Internal Relay Failure
FuncEnab → No Param No Parameters
Options → Opl NoTrip [NoTrip / Trip]
TripLev → No Param No Parameters
Timers → No Param No Parameters
Description of variables
Opl : The variable “ Opl ” can be programmed to trip the output relays same as the other
protection functions (Opl = TRIP), or to only operate the “IRF” signal led without tripping
the output relays (Opl = NoTRIP).
Trip when : an internal fault in the relay is detected (see Diagnostics)
When the function is tripped : Signalization = Led “ PWR/I.R.F. ” blink
Last Trip = Is recorded
Function reset when : it returns to normal operation
Led reset when : Push-button is pressed
