Bay protection functions REB500
Signal Description
13790_BP External s
tart BFP
Breaker failure protection with three
-
phase starting. The
breaker failure protection timer starts when this signal is acti-
vated regardless of the current measurement.
This signal is directly activated by the bay protection and does
not therefore appear as a binary input signal.
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 sys-
tem. 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 t
hose 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.

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.

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 ar
e blocked throughout the
system (internal processing of the functions continues and
therefore measurements and signals continue to be displayed
on the local HMI).
