Technical manual
Description
The check zone release function for BBP is bypassed.
The differential currents of the check zone exceed the set alarm level.
BFP tripped in time step 1.
BFP tripped in time step 2.
BFP is blocked (either a bay unit or the entire system).
EFP has tripped.
EFP is blocked (either a bay unit or the entire system).
OCDT has tripped.
OCDT is blocked (either a bay unit or the entire system).
One of the feeder time-overcurrent functions has picked up.
This signal must be configured in the central unit and defined as a DR
trigger, so that the DR function of the central unit is basically able to be
started by the following input signals for general start of DR:
• 36705_General Start DR
• 16750_Start DR_10 or 16760_BP General Start DR
Without this signal, the central unit will not respond to a General Start DR.
Signals tripping by PDF.
PDF is blocked (either individual bays or the entire system).
UV has been activated (either individual bays or throughout the system).
The outputs of the bay protection functions are blocked (either individual
bays or throughout the system).
Certain bay protection output signals in specific bays or throughout the
entire system are blocked (Must be configured together with the
corresponding BU output signal 29410_BP partial blocked).

This output signal is also used as an indication, that a
general start of all appropriately configured fault
recorder has taken place in the system.
