Parameter
Description
13797_BP Start BFP L0
Breaker failure protection with L0 - starting. The breaker failure protection timer
starts when this signal is activated by BP functions and the BFP measures a
current in the neutral system. This signal is directly activated by the bay
protection and does not therefore appear as a binary input signal.
16760_BP Global Start DR
Starts those disturbance recorders in the bay units that are configured. The
signal Central start DR in the bay units must be configured. This signal is
directly activated by the BP unit and does not therefore appear as a binary input
signal.
29110_BP TRIP
Three phase tripping commands of the bay protection functions grouped to one
three phase tripping command.
29115_BP TRIP L1
Phase L1 tripping commands of the bay protection functions grouped to one L1
tripping command.
29120_BP TRIP L2
Phase L2 tripping commands of the bay protection functions grouped to one L2
tripping command.
29125_BP TRIP L3
Phase L3 tripping commands of the bay protection functions grouped to one L3
tripping command.

Signal
Description
19205_Block BP
The BP output signals of the respective bay unit are blocked. (Internal
processing of the functions continues and therefore, measurements and
signals continue to be displayed on the local HMI.)
19600_Activation BP ParSet_1
The protection functions and settings assigned to parameter set 1 are
active. They remain active after the signal has been reset.
19605_Activation BP ParSet_2
The protection functions and settings assigned to parameter set 2 are
active. They remain active after the signal has been reset.
19610_Activation BP ParSet_3
The protection functions and settings assigned to parameter set 3 are
active. They remain active after the signal has been reset.
19615_Activation BP ParSet_4
The protection functions and settings assigned to parameter set 4 are
active. They remain active after the signal has been reset.

Signal
Description
39205_Block BP
The bay protection output signals are blocked throughout the system
(internal processing of the functions continues and therefore
measurements and signals continue to be displayed on the local HMI).

Signal
Description
29405_BP blocked
Signals that the outputs of the bay protection functions are blocked (either
the bay concerned or throughout the system).
29410_BP partial blocked
Signals certain bay protection functions are blocked (Signal must be set
explicitly in the bay protection).
29600 ParaSet_1 active
Signals that parameter set 1 is active (activated via the station bus or an
input signal).
